Background: To determine factors associated with age-disparate sexual partners among Vancouver gay, bisexual and other men who have sex with men (GBM).Methods: Sexually active GBM aged ≥16 years were recruited from February 2012 to February 2014. Participants self-completed a questionnaire on demographics, attitudes and sexual behaviour and substance use at last sexual event with five most recent partners. Two generalised linear mixed models identified factors associated with: (1) 'same-age' (referent), 'younger' or 'much-younger' and (2) 'same-age' (referent), 'older' or 'much-older' partners. Statistical interactions between age and HIV status were tested.Results: Participants (n=719) were predominantly gay (85.1%), White (75.0%), HIV-negative/unknown status (72.9%) with median age of 33 years (Q1,Q3: 26,47). A minority of sexual events were reported with much-older/much-younger partners (13.7%). In the multivariable models, GBM reporting older partners were more likely to be Asian or Latino, have greater Escape Motivation scores, report their partner used erectile dysfunction drugs (EDDs) and have received something for sex; compared with condom-protected insertive anal sex, participants with older partners were more likely to report condomless insertive anal sex with a serodiscordant or unknown status partner or no insertive anal sex. GBM reporting older partners were less likely to be bisexual-identified, have given something for sex and report event-level alcohol and EDD use. GBM reporting younger partners were more likely to have annual incomes >$30 000 and have met their partner online. As per significant statistical interactions, age-disparate relations were more common for younger HIV-positive and older HIV-negative GBM.Conclusions: Differences among age-disparate partners highlight important targets for health promotion and future research.

Background: People living with HIV (PLHIV) who are also marginalized by social and structural inequities often face barriers to accessing and adhering to HIV treatment and care. The Dr. Peter Centre (DPC) is a non-profit integrated care facility with a supervised injection room that serves PLHIV experiencing multiple barriers to social and health services in Vancouver, Canada. This study examines whether the DPC is successful in drawing in PLHIV with complex health issues, including addiction. Methods: Using data collected by the Longitudinal Investigations into Supportive and Ancillary health services (LISA) study from July 2007 to January 2010, linked with clinical variables available through the British Columbia Centre for Excellence in HIV/AIDS Drug Treatment Program, we identified DPC and non-DPC clients with a history of injection drug use. Bivariable and multivariable logistic regression analyses compared socio-demographic and clinical characteristics of DPC clients (n = 76) and non-DPC clients (n = 482) with a history of injection drug use. Results: Of the 917 LISA participants included within this analysis, 100 (10.9%) reported being a DPC client, of which 76 reported a history of injection drug use. Adjusted results found that compared to non-DPC clients with a history of injection drug use, DPC-clients were more likely to be male (AOR: 4.18, 95% CI = 2.09-8.37); use supportive services daily vs. less than daily (AOR: 3.16, 95% CI = 1.79-5.61); to have been diagnosed with a mental health disorder (AOR: 2.11; 95% CI: 1.12-3.99); to have a history of interpersonal violence (AOR: 2.76; 95% CI: 1.23-6. 19); and to have ever experienced ART interruption longer than 1 year (AOR: 2.39; 95% CI: 1.38-4.15). Conclusions: Our analyses suggest that the DPC operating care model engages PLHIV with complex care needs, highlighting that integrated care facilities are needed to support the multiple intersecting vulnerabilities faced by PLHIV with a history of injection drug use living within urban centres in North America and beyond.

Background: Community-based HIV, harm reduction, and addiction research increasingly involve members of affected communities as Peer Research Associates (PRAs)-individuals with common experiences to the participant population (e.g. people who use drugs, people living with HIV [PLHIV]). However, there is a paucity of literature detailing the operationalization of PRA hiring and thus limited understanding regarding how affected communities can be meaningfully involved through low-barrier engagement in paid positions within community-based participatory research (CBPR) projects. We aim to address this gap by describing a low-threshold PRA hiring process. Results: In 2012, the BC Centre for Excellence in HIV/AIDS and the Dr. Peter AIDS Foundation collaborated to develop a mixed-method CBPR project evaluating the effectiveness of the Dr. Peter Centre (DPC)-an integrative HIV care facility in Vancouver, Canada. A primary objective of the study was to assess the impact of DPC services among clients who have a history of illicit drug use. In keeping with CBPR principles, affected populations, community-based organizations, and key stakeholders guided the development and dissemination of a low-barrier PRA hiring process to meaningfully engage affected communities (e.g. PLHIV who have a history of illicit drug use) in all aspects of the research project. The hiring model was implemented in a number of stages, including (1) the establishment of a hiring team; (2) the development and dissemination of the job posting; (3) interviewing applicants; and (4) the selection of participants. The hiring model presented in this paper demonstrates the benefits of hiring vulnerable PLHIV who use drugs as PRAs in community-based research. Conclusions: The provision of low-barrier access to meaningful research employment described herein attempts to engage affected communities beyond tokenistic involvement in research. Our hiring model was successful at engaging five PRAs over a 2-year period and fostered opportunities for future paid employment or volunteer opportunities through ongoing collaboration between PRAs and a diverse range of stakeholders working in HIV/AIDS and addictions. Additionally, this model has the potential to be used across a range of studies and community-based settings interested in meaningfully engaging communities in all stages of the research process.

Background: In South Africa, pervasive age and gender inequities have been exacerbated by the COVID-19 pandemic and public health response. We aimed to explore experiences of the COVID-19 pandemic among youth in eThekwini district, South Africa., Methods: Between December 2021-May 2022 we explored experiences of the COVID-19 pandemic on youth aged 16-24 residing in eThekwini, South Africa. We collated responses to the open-ended question "Has the COVID-19 pandemic affected you in any other way you want to tell us about?" in an online survey focused on understanding the pandemic's multi-levelled health and social effects. We used a thematic analysis to summarise the responses., Results: Of 2,068 respondents, 256 (12.4%, median age = 22, 60.9% women) completed the open-ended survey question (11% in isiZulu). Results were organized into three main themes encompassing (1) COVID-19-related loss, fear, grief, and exacerbated mental and physical health concerns; (2) COVID-19-related intensified hardships, which contributed to financial, employment, food, education, and relationship insecurities for individuals and households; and (3) positive effects of the pandemic response, including the benefits of government policies and silver linings to government restrictions., Conclusions: We found that South African youth experienced significant grief and multiple losses (e.g., death, income, job, and educational) during the COVID-19 pandemic. Trauma-aware interventions that provide economic and educational opportunities must be included in post-COVID recovery efforts., (© 2024. The Author(s).)

Importance: Transgender and gender-diverse (TGD) communities experience disproportionate levels of violence, yet due to limitations in measuring TGD identity, few state-representative estimates are available., Objective: To assess gender identity differences in experiences of violence among adults., Design, Setting, and Participants: Cross-sectional data from the 2023 California Violence Experiences (CalVEX) survey, weighted to provide state-representative estimates, was used to assess associations between gender identity and past-year experiences of violence among adults 18 years and older. Data were analyzed from June to December 2023., Exposure: Gender identity (cisgender women, cisgender men, transgender women, transgender men, and nonbinary individuals)., Main Outcomes and Measures: Experience of physical violence (including physical abuse and threat or use of a weapon), sexual violence (verbal sexual harassment, homophobic or transphobic slurs, cyber and physically aggressive sexual harassment, and forced sex), and intimate partner violence (IPV; emotional, physical, or sexual violence) using age-adjusted logistic regression., Results: In total 3560 individuals (weighted cumulative response rate, 5%) completed the 2023 CalVEX survey, with 1978 cisgender women, 1431 cisgender men, 35 transgender women, 52 transgender men, and 64 nonbinary respondents (mean [SD] age, 47.1 [17.5] years; 635 [17%] were Asian, 839 [37%] were Hispanic, and 1159 [37%] were White). Past-year physical violence was reported by 22 transgender men (43%), 9 transgender women (24%), and 9 nonbinary respondents (14%). Past-year sexual violence was reported by 23 transgender men (42%), 11 transgender women (14%), and 31 nonbinary respondents (56%). Compared with cisgender women, transgender women and transgender men had greater risk of past-year physical violence (any form) (transgender women adjusted incidence rate ratio [AIRR], 6.7; 95% CI, 2.5-18.2; transgender men AIRR, 9.7; 95% CI, 5.3-17.7), as well as past-year IPV (any form) (transgender women AIRR, 3.2; 95% CI, 1.3-8.0; transgender men AIRR, 6.7; 95% CI, 4.0-11.3). Relative to cisgender women, transgender men (AIRR, 3.0; 95% CI, 1.7-5.1) and nonbinary respondents (AIRR, 3.3; 95% CI, 2.1-5.2) had greater risk of past-year sexual violence (any form)., Conclusions and Relevance: In this survey study of adults in California, results showed that TGD individuals, especially transgender men, are at higher risk of experiencing all forms of violence relative to cisgender women. Results highlight the need for gender-affirming violence prevention and intervention services as well as policies that protect TGD individuals from discriminatory violence.

To deepen our understanding of the impact of the COVID-19 pandemic on intimate and/or sexual relationships, we conducted a qualitative study among 26 South African women and men aged 21-30 years in Durban and Soweto between September 2020 and March 2021. Overall, 13 women and 12 men who had been in an intimate and/or sexual relationship since the start of the COVID-19 pandemic were asked about the impact of COVID-19 on their relationships with their current or most recent primary partners. Data were analysed using reflexive thematic analysis. The three most common impacts of the COVID-19 pandemic on relationships were on (i) communication and connection; (ii) strained relationships; and (iii) job and economic loss. Both women and men discussed how COVID-19-related lockdowns provided opportunities to foster better communication, connection and support to one another. However, too little or too much time together strained relationships. Finally, income loss among young men meant that some young women became the primary income earner, changing relationship power dynamics. Findings highlight the importance of young people's relationships and the need for action to support young people in building positive relationships in challenging times.

Objective: To estimate the effect of income change on difficulty accessing food since the COVID-19 pandemic for South African youth and evaluate whether this effect was modified by receiving social grants., Design: A cross-sectional, online survey was conducted between December 2021 and May 2022. Primary outcome was increased difficulty accessing food since the COVID-19 pandemic. Income change was categorised as 'Decreased a lot', 'Decreased slightly' and 'Unchanged or increased'. Multivariable logistic regressions were used, with an interaction term between social grant receipt and income change., Setting: eThekwini district, South Africa., Participants: Youth aged 16-24 years., Results: Among 1,620 participants, median age was 22 years (IQR 19-24); 861 (53 %) were women; 476 (29 %) reported increased difficulty accessing food; 297 (18 %) reported that income decreased a lot, of whom 149 (50 %) did not receive social grants. Experiencing a large income decrease was highly associated with increased difficulty accessing food during the COVID-19 pandemic (adjusted OR [aOR] 3·63, 95 % CI 2·70, 4·88). The aOR for the effect of a large income decrease on difficulty accessing food, compared to no income change, were 1·49 (95 % CI 0·98, 2·28) among participants receiving social grants, and 6·63 (95 % CI 4·39, 9·99) among participants not receiving social grants., Conclusions: While social grant support made a great difference in lowering the effect of income decrease on difficulty accessing food, it was insufficient to fully protect youth from those difficulties. In post-pandemic recovery efforts, there is a critical need to support youth through economic empowerment programming and food schemes.

Understanding the unique ways in which queer, trans, and non-monogamous young women and non-binary youth navigate and negotiate equitable intimate relationships is a first step toward strong research, programs/resources, and policies to support healthy relationship dynamics across the life course. Using a youth-engaged collaborative Reflexive Thematic Analysis, we aimed to explore how youth of diverse genders and relationship experiences understand gender equity in their relationships. Thirty cis- and transgender inclusive young women (46.7%) and non-binary youth (53.3%) aged 17-29 who were in a current (76.6%) or recent (in past 12 months, 23.4%) non-heterosexual and/or non-monogamous intimate relationship and residing in British Columbia, Canada, completed qualitative interviews between August and November 2022. Of the 30 youth, 53.3% reported having experience living as a trans person, 33.3% identified only as bisexual and 10% identified as only lesbian or gay, whereas the remaining 56.7% identified with ≥1 of: queer, pansexual, and demisexual. Participants identified that relationship equity requires: 1) Moving away from cis-heteronormative conceptualizations of gender roles and norms; 2) Actively working to dismantle hierarchal power structures by sharing power, responsibility, labour, and decision-making; and 3) Accommodating and affirming each person's unique needs and identities in a relationship. For theme one, youth further described the ways in which they re-imagined relationship norms and discussed the various challenges to resisting ingrained hierarchical cis-heteronormativity. This research contributes a greater understanding of how to create equitable and healthy relationships and has important implications for healthcare providers, educators, and policymakers working with queer, transgender, and non-monogamous youth., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2024 The Authors.

Background: Economic hardship is a potential trigger for intimate partner violence (IPV) perpetration. While higher IPV rates have been reported in low-income regions, few African studies have focused on IPV being triggered by economic hardship among young men during the COVID-19 pandemic. We therefore estimated economic hardship's effect on IPV perpetration by young men in eThekwini District, South Africa, during the COVID-19 pandemic., Methods: A cross-sectional survey of COVID-19 pandemic experiences was conducted among youth aged 16-24 years through an anonymous self-administered questionnaire, including questions about economic hardship (increased difficulty accessing food or decreased income) and IPV perpetration. A prespecified statistical analysis plan with a directed acyclic graph of assumed exposure, outcome, and confounder relationships guided our analyses. We measured association of economic hardship and IPV perpetration through odds ratios (ORs) computed from a multivariable logistic regressions adjusted for measured confounders. Secondary outcomes of physical and sexual IPV perpetration were analyzed separately using the same specifications. Propensity score matching weights (PS-MW) were used in sensitivity analyses. Analysis code repository: https://github.com/CAndrewBasham/Economic&#95;Hardship&#95;IPV&#95;perpetration/ RESULTS: Among 592 participants, 12.5% reported perpetrating IPV, 67.6% of whom reported economic hardship, compared with 45.6% of those not reporting IPV perpetration (crude OR = 2.49). Median age was 22 years (interquartile range 20-24). Most (80%) were in a relationship and living together. Three quarters identified as Black, 92.1% were heterosexual, and half had monthly household income < R1600. We estimated an effect of economic hardship on the odds of perpetrating IPV as OR = 1.83 (CI 0.98-3.47) for IPV perpetration overall, OR = 6.99 (CI 1.85-36.59) for sexual IPV perpetration, and OR = 1.34 (CI 0.69-2.63) for physical IPV perpetration. PS-MW-weighted ORs for IPV perpetration by economic hardship were 1.57 (overall), 4.45 (sexual), and 1.26 (physical)., Conclusion: We estimated 83% higher odds of self-reported IPV perpetration by self-reported economic hardship among young South African men during the COVID-19 pandemic. The odds of sexual IPV perpetration were The seven-times higher by economic hardship, although with limited precision. Among young men in South Africa, economic hardship during COVID-19 was associated with IPV perpetration by men. Our findings warrant culturally relevant and youth-oriented interventions among young men to reduce the likelihood of IPV perpetration should they experience economic hardship. Further research into possible causal mechanisms between economic hardship and IPV perpetration could inform public health measures in future pandemic emergencies., (© 2024. The Author(s).)

Efforts to advance sexual health globally require greater understandings of youth intimate relationship dynamics. Among 38 South African youth (21 women/17 men aged 21-30 from Durban and Soweto) we conducted qualitative cognitive interviews to explore how gender and power intersect to shape intimate relationship dynamics (October 2019-March 2021). Participants discussed perceptions and relevance of each of 13 items comprising the Sexual Relationship Power (SRP) scale, a widely used measure of gender equity, and the influence of SRP on youth sexual health. Data analysis was guided by constructivist grounded theory. The findings were organized using the socio-ecological model, revealing how gender and power intersected at multiple levels to influence youth intimate relationships. Key influencing factors included individual-level gender attitudes, male partner expectations, and women's resistance to dominance; intimate relationship-level power dynamics, consent, and intimacy; family-level household configurations and parental monitoring of daughters; and societal-level traditional gender norms. At all levels, women discussed resisting power inequities through communication and rejection of inequitable relationships. While men also displayed resistance to inequitable power structures, most upheld traditional gender norms through institutional affiliation (e.g. church) and deep-rooted socialized beliefs and attitudes. Efforts to improve youth sexual health require multileveled approaches that address inequitable power dynamics.

Background: Young women and Lesbian, Gay, Bisexual, Trans, Non-binary/no gender, or Questioning (LGBTQ+) youth in South Africa face some of the highest global levels of intimate partner violence (IPV). Given limited evidence in the wake of the COVID-19 pandemic, which has fuelled IPV globally, we aimed to describe and compare experiences and perpetration of IPV of youth aged 16-24 by sexual orientation and gender identity (SOGI)., Methods: During the study period (December 2021-May 2022), youth aged 16-24 from eThekwini district, South Africa completed an online survey to understand multilevel impacts of the pandemic on youth. Participants were asked about experiences and perpetration of physical IPV since the start of the COVID-19 pandemic (March 2020). Descriptive statistics and adjusted logistic regressions compared the likelihood of experiencing and/or perpetrating physical IPV between cisgender and transgender inclusive heterosexual men; heterosexual women; gay, bisexual, or questioning men [GBQM]; lesbian, gay, bisexual, or questioning women [LGBQW]; or gender/sexual non-conforming youth [non-conforming]., Results: Of 1,588 youth (mean age = 21.7 [SD = 2.3]; 71.7% Black) with non-missing SOGI and physical IPV data, 238 (15.0%) were LGBTQ+ (40.3% LGBQW and 36.1% non-conforming). Overall, 14.6% of respondents experienced physical IPV and 9.8% perpetrated physical IPV since the start of the pandemic, which differed by SOGI (12.3% of heterosexual men, 13.9% of heterosexual women, 22.0% of GBQM, 18.2% of LGBQW, and 25.0% of non-conforming youth experienced and 10.3% of heterosexual men; 7.7% of heterosexual women; 10.0% of GBQM; 18.2% of LGBQW; and 16.7% of non-conforming youth perpetrated). In adjusted models, compared to heterosexual women, non-conforming youth had increased odds of experiencing (adjusted odds ratio [aOR] = 2.36; 95%CI, 1.26-4.39) physical IPV and compared to heterosexual men, non-conforming youth had greater odds of perpetrating physical IPV (aOR = 2.19; 95%CI, 1.07-4.48) during the pandemic., Conclusion: Over one in six youth in our study experienced and one in ten perpetrated physical IPV since the onset of the COVID-19 pandemic, with gender and sexual non-conforming youth experiencing and perpetrating IPV at significantly greater rates than cisgender/heterosexual peers. Our findings highlight the need for gender transformative efforts that move beyond the gender binary to support healthy relationships and IPV prevention for LGBTQ + youth in South Africa and globally., (© 2023.

Survivors of adverse childhood experience are at elevated risk for psychological distress. In recent years, renewed interest in psychedelic medicine has highlighted the therapeutic potential of psilocybin for those who have experienced childhood adversity. However, recreational psilocybin use remains illegal and access to approved therapies is difficult. Such use provides an opportunity to explore the therapeutic potential of psilocybin for psychological distress among people with adverse childhood experiences. Therefore, we conducted an online survey to assess interest in, acceptability of, and experiences with psilocybin. We further explored whether the association between Adverse Childhood Experiences Questionnaire (ACEQ) scores and psychological distress was lower among those who had used psilocybin in the past three months. Results showed high levels of interest in and acceptability of psilocybin that did not differ across ACEQ scores. Results also showed that the effect of adverse childhood experiences on psychological distress was lower for people who had recently used psilocybin ( p  = .019). Taken together, these findings suggest that psilocybin therapy may be potentially acceptable and may feasibly help in supporting survivors of adverse childhood experiences with particularly strong benefits to those with more severe childhood adversity.

Objective: This study examines the association between parental engagement and subsequent delayed marriage of adolescent girls and, secondarily, to assess whether parental engagement is positively associated with girls' involvement in marital decision-making regarding husband selection., Methods: The study used longitudinal survey data from the Understanding the Lives of Adolescents and Young Adults (UDAYA) in Uttar Pradesh and Bihar, India. We analysed 6168 unmarried adolescent girls aged 15-19 years at wave 1 (2015-16) who were interviewed in wave 2 (2018-19). Our outcomes were delayed marriage of girls (unmarried vs. married at 20-22 vs. married at 18-19 vs. married at <18) and, among those married at <18 years, girls' involvement in husband selection (alone vs. with parents vs. not involved). Parental discussion around school performance, friendships, menstruation, pregnancy, free time, and personal issues were the exposure variables. We applied unadjusted and adjusted multinomial regression models to assess associations between our exposure variables and each outcome variable., Results: From wave 1 to wave 2, 1551 girls (31.2%) married; 567 girls (12.5%) married as minors (<18 years). We found that parental discussion around school performance (relative risk ratio [RRR]: 1.33), friendship (RRR: 1.37) and personal matters (RRR: 1.29) were positively associated with remaining unmarried relative to early marriage of girls. However, discussion with parents about menstruation was negatively associated with marriage at 20-22 (RRR: 0.67) and remaining unmarried (RRR: 0.80), compared to early marriage. Discussing school performance was negatively associated with marriage at 18-19 (RRR: 0.62) and at 20-22 (RRR: 0.50), relative to early marriage. Discussing personal issues with parents was positively associated with joint parent-girl decision-making regarding husband selection, relative to parents alone selecting the husband (RRR: 1.43)., Conclusions: Parental engagement on school performance, friendship, and personal issues in early adolescence may help delay marriage and support marital choice for girls in India., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Background: Climate change is a threat to the mental and emotional wellbeing of all humans, but young people are particularly vulnerable. Emerging evidence has found that young people's awareness of climate change and the danger it poses to the planet can lead to negative emotions. To increase our understanding about this, survey instruments are needed that measure the negative emotions young people experience about climate change., Research Questions: (1) What survey instruments are used to measure negative emotional responses to climate change in young people? (2) Do survey instruments measuring young people's negative emotional responses to climate change have evidence of reliability and validity? (3) What factors are associated with young people's negative emotional responses to climate change?, Methods: A systematic review was conducted by searching seven academic databases on November 30, 2021, with an update on March 31, 2022. The search strategy was structured to capture three elements through various keywords and search terms: (1) negative emotions, (2) climate change, and (3) surveys., Results: A total of 43 manuscripts met the study inclusion criteria. Among the 43 manuscripts, 28% focused specifically on young people, while the other studies included young people in the sample but did not focus exclusively on this population. The number of studies using surveys to examine negative emotional responses to climate change among young people has increased substantially since 2020. Survey instruments that examined worry or concern about climate change were the most common., Conclusion: Despite growing interest in climate change emotions among young people, there is a lack of research on the validity of measures of such emotions. Further efforts to develop survey instruments geared to operationalize the emotions that young people are experiencing in relation to climate change are needed., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Intergenerational differences in inequitable gender attitudes may influence developmental outcomes, including education. In rural Karnataka, India, we examined the extent of intergenerational (adolescent girls [AGs] vs. older generation family members) dis/agreement to attitudes around gendered power inequities, including gender roles and violence against women (VAW). Unadjusted and adjusted logistic regression examined associations between intergenerational dis/agreement to attitude statements and AGs' future educational and career aspirations. Of 2,457 AGs, 90.9% had a matched family member (55% mothers). While traditional gender roles were promoted intergenerationally, more AGs supported VAW than family members. In adjusted models, discordant promotion of traditional gender roles and concordant disapproval of VAW were associated with greater aspirations. Results highlight the need for family-level programming promoting positive modeling of gender-equitable attitudes.

Little is known about how the co-occurrence of psychosocial factors affect sub-populations of people living with HIV (PLWH). We used cross-sectional data from 999 PLWH, aged ≥19, accessing antiretroviral therapy (ART) in British Columbia, Canada (2007-2010) to examine associations between psychosocial factors and ART-related outcomes separately for trans/cis inclusive women; heterosexual men; and gay, bisexual, and other men who have sex with men (gbMSM). Multivariable logistic regression examined associations between psychosocial factors (0-3): any violence in the past 6 months, depressive symptoms in the past week, and current street drug use (heroin, crack, meth or speedball) with sub-optimal adherence (outcome 1: average annual ART adherence <95% from interview until end of follow-up, death, or December 31st, 2018) and ever viral rebound (outcome 2) adjusting for potential confounders. Of 999 PLWH (264 women, 382 heterosexual men, and 353 gbMSM), women and heterosexual men had significantly higher median counts than gbMSM. Overall, higher counts were associated with sub-optimal adherence (adjusted odds ratio [aOR] = 1.26/1-unit increase, 95%CI = 1.07-1.49). All effect estimates were of a greater magnitude among gbMSM, but not significant for women or heterosexual men, highlighting the need for population (e.g., gender and sexual orientation)-centered care and research.

Objective: To describe the prevalence of diagnosed depression, anxiety, bipolar disorder, and schizophrenia in people with HIV (PWH) and the differences in HIV care continuum outcomes in those with and without mental health disorders (MHDs)., Design: Observational study of participants in the North American AIDS Cohort Collaboration on Research and Design., Methods: PWH (≥18 years) contributed data on prevalent schizophrenia, anxiety, depressive, and bipolar disorders from 2008 to 2018 based on International Classification of Diseases code mapping. Mental health (MH) multimorbidity was defined as having two or more MHD. Log binomial models with generalized estimating equations estimated adjusted prevalence ratios (aPR) and 95% confidence intervals for retention in care (≥1 visit/year) and viral suppression (HIV RNA ≤200 copies/ml) by presence vs. absence of each MHD between 2016 and 2018., Results: Among 122 896 PWH, 67 643 (55.1%) were diagnosed with one or more MHD: 39% with depressive disorders, 28% with anxiety disorders, 10% with bipolar disorder, and 5% with schizophrenia. The prevalence of depressive and anxiety disorders increased between 2008 and 2018, whereas bipolar disorder and schizophrenia remained stable. MH multimorbidity affected 24% of PWH. From 2016 to 2018 (N = 64 684), retention in care was marginally lower among PWH with depression or anxiety, however those with MH multimorbidity were more likely to be retained in care. PWH with bipolar disorder had marginally lower prevalence of viral suppression (aPR = 0.98 [0.98-0.99]) as did PWH with MH multimorbidity (aPR = 0.99 [0.99-1.00]) compared with PWH without MHD., Conclusion: The prevalence of MHD among PWH was high, including MH multimorbidity. Although retention and viral suppression were similar to people without MHD, viral suppression was lower in those with bipolar disorder and MH multimorbidity., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objective: We aimed to characterize mortality among people with HIV (PWH) and psychotic disorders (PWH/psychosis+) vs. PWH alone (PWH/psychosis-)., Method: A population-based analysis of mortality in PWH (age ≥19) in British Columbia (BC) from April 1996 to March 2017 was conducted using data from the Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) study. Deaths were identified from the Vital Statistics Data (classified as HIV vs. non-HIV causes). Mortality trends across all fiscal years were examined. Cox models assessed the hazard of psychotic disorders on mortality; possible differences between schizophrenia and nonschizophrenia types of psychotic disorders were also evaluated., Results: Among 13 410 PWH included in the analysis, 1572 (11.7%) met the case definition for at least one psychotic disorder. Over the study period, 3274 deaths (PWH/psychosis-: n  = 2785, PWH/psychosis+: n  = 489) occurred. A decline over time in all-cause mortality and HIV-related mortality was observed in both PWH/psychosis+ and PWH/psychosis- ( P value <0.0001). A decline in non-HIV mortality was observed among PWH/psychosis- ( P value = 0.003), but not PWH/psychosis+ ( P value = 0.3). Nonschizophrenia psychotic disorders were associated with increased risk of mortality; adjusted hazard ratios with (95% confidence intervals): all-cause 1.75 (1.46-2.09), HIV-related 2.08 (1.60-2.69), non-HIV-related 1.45 (1.11-1.90). Similar associations between schizophrenia and mortality were not observed., Conclusion: People with co-occurring HIV and nonschizophrenia psychotic disorders experienced a significantly higher risk of mortality vs. PWH without any psychotic disorder. Implementing care according to syndemic models considering interactions between HIV and particularly episodic psychotic disorders could help manage mortality risk more effectively among PWH/psychosis+., (Copyright © 2022 Wolters Kluwer Health, Inc.

Introduction: Many young people report experiencing negative emotional responses to their awareness of climate change and the threats it poses to their future. With that, an increasing number of survey instruments have been developed to examine young people's negative emotional responses to their awareness of climate change. This report describes a protocol for a systematic review that aims to identify, synthesise and critically appraise how negative emotional responses to climate change among young people have been measured in survey research. The research questions addressed in this review are: (1) How has negative emotional responses to climate change been defined and measured among young people? (2) How do survey instruments measuring young people's negative emotional responses to climate change vary in terms of reliability and validity? (3) What factors are associated with negative emotional responses to climate change among young people?, Methods and Analysis: Seven academic databases (CINAHL, ERIC, MEDLINE, PsycINFO, Web of Science, Scopus, and Environment Complete) will be searched to retrieve studies published between 1 January 2006 and 31 March 2022 and published in English. Studies including survey instruments that measure negative emotional responses among young people (aged 10-24 years) will be eligible for inclusion. Targeted journals will be hand-searched. This review will follow Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines for systematic reviews. The methodological quality, in terms of reliability and validity, of the included studies will be assessed using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist for risk of bias of patient-reported outcome measures. To rate the quality of the instruments, we will use a modified Grading of Recommendations, Assessment, Development and Evaluations technique defined by the COSMIN guidelines., Ethics and Dissemination: Ethical approval is not applicable for this study. We will disseminate the findings through publication in peer-reviewed journals and presentations., Prospero Registration Number: CRD42022295733., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: Sexual relationship power (SRP) inequities, including having a controlling partner, have not been widely examined among women living with HIV (WLWH). We measured the prevalence and key outcomes of relationship control among WLWH in Canada., Methods: Baseline data from WLWH (≥16 years), reporting consensual sex in the last month enrolled in a Canadian community-collaborative cohort study in British Columbia, Ontario, and Quebec, included the relationship control SRP subscale by Pulerwitz (2000). Scale scores were dichotomized into medium/low (score = 1-2.82) vs. high relationship control (score = 2.82-4), and high scores indicate greater SRP equity. Cronbach's alpha assessed scale reliability. Bivariate analyses compared women with high vs. medium/low relationship control. Crude and adjusted multinomial regression examined associations between relationship control and condom use [consistent (ref), inconsistent, or never]; any sexual, physical, and/or emotional violence; and physical and/or sexual violence [never (ref), recent (≤3 months ago), and previous (>3 months ago)]., Results: Overall, 473 sexually active WLWH (33% of cohort), median age = 39 (IQR = 33-46) years, 81% on antiretroviral therapy, and 78% with viral loads <50 copies/mL were included. The subscale demonstrated good reliability (Cronbach's alpha = 0.92). WLWH with high relationship control (80%) were more likely ( P < 0.05) to be in a relationship, have no children, have greater resilience, and report less sociostructural inequities. In adjusted models, high relationship control was associated with lower odds of inconsistent vs. consistent condom use [adjusted odds ratio (aOR): 0.39 (95% confidence interval: 0.18 to 0.85)], any recent violence [aOR: 0.14 (0.04-0.47)] as well as recent physical and/or sexual [aOR : 0.05 (0.02-0.17)] but not previous violence (vs. never)., Discussion: Prioritizing relationship equity and support for WLWH is critical for addressing violence and promoting positive health outcomes., Competing Interests: CHIWOS is funded by the Canadian Institutes of Health Research (CIHR), the CIHR Canadian HIV Trials Network (CTN 262), the Ontario HIV Treatment Network (OHTN), and the Academic Health Science Centers (AHSC) Alternative Funding Plans (AFP) Innovation Fund.

Background: Gender inequity and the subsequent health impacts disproportionately affect communities in the Global South. However, most gender equity measures, such as Pulerwitz' (2000) Sexual Relationship Power Scale (SRPS), are developed and validated in the Global North and then applied in Global South settings without investigation of context applicability or validity. This study examines the SRPS' validity evidence, comprehensiveness, and contemporary relevance for young South African women and men., Methods: Between 2019 and 2021, 38 cognitive interviews (CIs) were conducted among previous participants of a South African youth cohort study 'AYAZAZI' (2015-2017) to explore youth's perceptions of the SRPS. The SRPS measures women's perceptions of their partner's controlling behaviours, and men's perceptions of their own controlling behaviours. Using CIs, participants responded to a 13-item adaptation of the SRPS for use among South African youth (strongly agree-strongly disagree), and then were asked to think-aloud their reasoning for responses, their understanding and perceived relevance of each item, and made overall suggestions for scale adaptations. An item appraisal coding process was applied, whereby Cognitive Coding assessed the types of cognitive problems youth had with understanding the items, and Question Feature Coding assessed which item features caused problems for participant understandings. Finally, youth recommendations for scale adaptations were summarized., Results: Overall, 21 women and 17 men aged 21-30 participated in CIs in Durban and Soweto, South Africa. Cognitive Coding revealed 1. Comprehension issues, and 2. Judgements related to items' applicability to lived experiences and identities (e.g., being unmarried). Question Feature Coding revealed items' 1. Lack of clarity or vagueness in wording and 2. Logical problems in assumptions leading to multiple interpretations (e.g., item 'my partner always need to know where I am' interpreted as both controlling and caring behaviour). Multiple, overlapping issues revealed how many items failed to "fit" within the present-day living realities of South African youth. Youth recommended several item adaptations and additions, including strength-based items, to existing measures of gender equity and relationship power., Conclusion: Given identified issues, several adaptations including revising items to be more inclusive, contemporary, context specific, relational, and strength-based are needed to validly measure gender equity and power dynamics within the relationships of South African youth., (© 2022.

Gender inequity, including low sexual relationship power (SRP), is an important determinant of intimate partner violence (IPV) and negative sexual, reproductive, and mental health. Different versions of the Sexual Relationship Power Scale (SRPS) are commonly used within youth studies to examine how gender inequities, including controlling behaviors, in heterosexual relationships impact the lives of young people in sub-Saharan Africa. This review aims to (1) describe definitions and measures of SRP within sub-Saharan African youth studies and (2) review and summarize associations between SRP equity, IPV, and sexual, reproductive, and mental health. After searching Pubmed, Ovid Med, Psych info, Web of Science, Google Scholar, and relevant research forums, 304 papers were identified, of which 29 papers based on 15 distinct studies (published 2004-2019) met our criteria for being youth-specific, conducted in sub-Saharan Africa, and including a quantitative measure of SRP. Details of each SRPS are described, including any adaptations and psychometric properties, as well as associations with IPV, sexual, reproductive, and mental health behaviors and outcomes. Results indicate that there are variations to the SRPS, and a paucity of evidence has detailed the psychometric properties of such measures within sub-Saharan African youth studies. Measures of SRP equity are associated with experiences (among women) and perpetration of (among men) IPV as numerous pathways to HIV risk; however, the evidence remains mixed. In order to address overlapping epidemics of violence against women and HIV, efforts are needed to ensure that measures, including the SRPS, are valid and reliable among highly affected populations.

Background: Intimate partner violence (IPV) may affect the HIV-treatment cascade., Setting: Four high HIV-prevalence DREAMS health districts in South Africa., Methods: Secondary analysis of cross-sectional data collected March 2017-June 2018, using random household sample of young (12-24 years) girls and women. Face-to-face interviews assessed IPV and HIV-status knowledge, and finger-prick blood draws assessed ART (antiretroviral therapy) uptake and viral suppression. We used logistic regression to estimate crude and adjusted effects of IPV on HIV knowledge, ART uptake, and viral suppression., Results: Of 18,230 adolescent girls and young women, 8413 (46%) reported ever having had sex, of whom 1118 (13%) were HIV positive. The 90:90:90 benchmarks were 61% knew their status, 86% had ART present in their blood sample, and 91% were virally suppressed. Among the entire sample of young women living with HIV, 65.6% were virally suppressed. Past year IPV was reported by 15%. In adjusted models, IPV trended toward increasing the odds that a young woman was aware she was living with HIV [adjusted odds ratios (aOR) = 1.40, 2.00-9.98, P = 0.067]. There was no association between IPV and reduced treatment use (aOR = 0.73, 0.41-1.29). IPV was independently associated with reduced viral suppression (aOR = 0.30, 0.13-0.66)., Conclusions: Addressing the role of IPV in undermining the treatment cascade for adolescent and young women is a critical issue for HIV programming., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 The Author(s).

Objectives: People living with human immunodeficiency virus in Canada can face criminal charges for human immunodeficiency virus non-disclosure before sex, unless a condom is used and their viral load is <1500 copies/mL. We measured the reported impact of human immunodeficiency virus non-disclosure case law on violence from sexual partners among women living with human immunodeficiency virus in Canada., Methods: We used cross-sectional survey data from wave 3 participant visits (2017-2018) within Canadian HIV Women's Sexual and Reproductive Health Cohort Study; a longitudinal, community-based cohort of women living with human immunodeficiency virus in British Columbia, Ontario and Quebec. Our primary outcome was derived from response to the statement: '[HIV non-disclosure case law has] increased my experiences of verbal/physical/sexual violence from sexual partners'. Participants responding 'strongly agree/agree' were deemed to have experienced increased violence due to the law. Participants responding 'not applicable' (i.e. those without sexual partners) were excluded. Multivariate logistic regression identified factors independently associated with increased violence from sexual partners due to human immunodeficiency virus non-disclosure case law., Results: We included 619/937 wave 3 participants. Median age was 46 (interquartile range: 39-53) and 86% had experienced verbal/physical/sexual violence in adulthood. Due to concerns about human immunodeficiency virus non-disclosure case law, 37% had chosen not to have sex with a new partner, and 20% had disclosed their human immunodeficiency virus status to sexual partners before a witness. A total of 21% self-reported that human immunodeficiency virus non-disclosure case law had increased their experiences of verbal/physical/sexual violence from sexual partners. In adjusted analyses, women reporting non-White ethnicity (Indigenous; African/Caribbean/Black; Other), unstable housing and high human immunodeficiency virus-related stigma had significantly higher odds of reporting increased violence from sexual partners due to human immunodeficiency virus non-disclosure case law., Conclusion: Findings bolster concerns that human immunodeficiency virus criminalization is a structural driver of intimate partner violence, compromising sexual rights of women living with human immunodeficiency virus. Human immunodeficiency virus non-disclosure case law intersects with other oppressions to regulate women's sexual lives.

Purpose: This study aimed at determining to what extent sexual minority status modifies the association between HIV risk behavior and prevalent mood or anxiety disorder diagnosis in British Columbia (BC), Canada, using a population-based survey., Methods: This analysis was based on the cross-sectional 2013-2014 Canadian Community Health Survey. The sample was restricted to respondents in BC with valid responses to the survey items considered. A multivariable logistic model, where the behavioral HIV risk score exposure was nested into the sexual minority status modifier, estimated the odds of having a prevalent mood or an anxiety disorder. The behavioral HIV risk score (0, 1, 2, ≥ 3) included the following five measures: (1) age at first intercourse < 14 years, (2) condom use during last intercourse, (3) history of sexually transmitted infections, (5) number of sexual partners in the past 12 months (< 4, ≥ 4), and substance use in the past 12 months., Results: Of the weighted sample (2,521,252), 97% (95% confidence interval (CI) 97-98) were heterosexual, while 3% (95% CI 2-3) were lesbian, gay, and bisexual (LGB). The prevalence of a mood or anxiety disorder diagnosis was 12% (95% CI 11-13). For every 1-level increment in the behavioral HIV risk score, the adjusted odds ratio of having a prevalent mood or anxiety disorder diagnosis was 1.29 (95% CI 1.03-1.54) for heterosexual respondents and 2.37 (95% CI 1.84-2.90) for LGB respondents., Conclusion: Sexual minority status modified the relationship between HIV risk behavior and prevalent mood or anxiety disorders, with a stronger association among LGB respondents. Healthcare providers should prioritize integrated care that addresses the intersectionality between sexual risk, substance use, and mood or anxiety disorders., (© 2021.

Objective: To assess the prevalence of food insecurity and the independent association between depression and food insecurity among youth living in two urban settings in South Africa., Methods: Baseline cross-sectional survey data was analysed from a prospective cohort study conducted between 2014 and 2016 among youth (aged 16-24 years) in Soweto and Durban. Interviewer-administered questionnaires collecting socio-demographic, sexual and reproductive health and mental health data were conducted. Household food insecurity was measured using the 3-item Household Hunger Scale, with food insecure participants defined as having 'moderate' or 'severe hunger' compared to 'no hunger'. Depression was assessed using the 10-item Center for Epidemiological Studies Depression (CES-D 10) Scale (range 0-30, probable depression ≥ 10). Multivariable logistic regression models were used to estimate the association between depression and food insecurity., Results: There were 422 participants. Median age was 19 years (interquartile range [IQR] 18-21) and 60% were women. Overall, 18% were food insecure and 42% had probable depression. After adjustment for socio-demographic variables (age, gender, female-headed household, household size and school enrolment), participants with probable depression had higher odds of being food insecure than non-depressed participants (2.79, 95%CI 1.57-4.94)., Conclusion: Nearly one-fifth of youth in this study were food insecure. Those with probable depression had increased odds of food insecurity. Interventions are needed to address food insecurity among urban youth in South Africa, combining nutritional support and better access to quality food with mental health support., (© 2021 John Wiley & Sons Ltd.)

Background: Understanding young women and men's perceived barriers and facilitators to participation in biomedical HIV prevention research is important for designing youth friendly services (YFS) and acceptable technologies, which are necessary for preventing high sustained HIV incidence in South Africa. This study explores the multileveled barriers and facilitators to young men and women's willingness to participate in hypothetical biomedical HIV prevention research. Methods: Eight age- (16-18 and 19-24 years) and gender-stratified focus group discussions (FGDs) were conducted using semi-structured interview guides to explore young South African women and men's willingness, perceived barriers, and facilitators to participating in biomedical HIV prevention research. FGD transcripts were uploaded to NVivo and coded collaboratively with youth study team members. Thematic analysis using Bronfenbrenner's ecological model (individual, inter-personal, community, and societal) was used to guide a deductive coding procedure, which was documented and compared by gender. Results: Thirty-one participants from Durban and 34 from Soweto participated in FGDs. Individual facilitators for participation were discussed more by young men and included financial incentives and altruism. Concerns about side-effects of biomedical products were a common barrier. Interpersonal relationships with peers, intimate partners and caregivers influenced young people's willingness to participate in HIV prevention research, more so among young women. For young women, gendered power dynamics and distrust of intimate partners and parents influenced both communication regarding participation and willingness to participate in research that is often stigmatized, due to societal norms around women's sexuality. On a societal level, participants expressed distrust in medical and research institutions, however a sense of community that was developed with the study staff of this project, was a motivator to participate in future studies. Discussion: At each level of the ecological model, we found participants expressed gendered barriers and facilitators for participation. Gender norms as well as distrust of partners, parents, and health care professionals were key barriers that cut across all levels. At each level participants discussed facilitators that were youth-engaged, underscoring the need to implement YFS, establish trust and address gender inequities within future biomedical HIV prevention studies wishing to engage and retain South African youth., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Closson, Lee, Dietrich, Beksinska, Hornschuh, Smith, Smit, Ndung'u, Brockman, Gray and Kaida.)

Our study aims to define and identify correlates of social isolation among people living with HIV (PLHIV). The Longitudinal Investigation into Supportive and Ancillary health services (LISA) study provided a cross-sectional analytic sample of 996 PLHIV in British Columbia, Canada (sampled between 2007 and 2010). Individuals marginalized by socio-structural inequities were oversampled; sampling bias was addressed through inverse probability of participation weighting. Through latent class analysis, three groups were identified: Socially Connected (SC) ( n = 364, 37%), Minimally Isolated (MI) ( n = 540, 54%) and Socially Isolated (SI) ( n = 92, 9%). Correlates of the SI and MI classes, determined through multivariable multinomial regression using the SC class as a reference, include: recent violence (aOR 1.61, 95%CI 1.28-2.02 [MI vs. SC]; aOR 2.04, 95%CI 1.41-2.96 [SI vs. SC]) and a mental health diagnosis (aOR 1.50, 95% CI 1.31-1.72 [MI vs. SC]; aOR 1.43, 95%CI 1.11-1.83 [SI vs. SC]). Women (aOR 0.47; 95%CI 0.32-0.68 [SI vs. SC]), individuals of Indigenous ancestry (aOR 0.59; 95%CI 0.40-0.87 [SI vs. SC]) and people identifying as gay or lesbian (aOR 0.37; 95%CI 0.26-0.52 [SI vs. SC]) were less likely to experience isolation. These findings highlight the importance of supporting communities fostering connectedness and identifies populations susceptible to isolation.

Introduction: Universal provision of effective antiretroviral medication has been essential to reduce mortality, increase longevity, and reduce onward transmission of HIV. This study aims to illuminate persistent threats to the health and longevity of under-served PLWH in British Columbia (BC), Canada., Methods: Between 2007 and 2010, 1000 PLWH across BC were enrolled in the Longitudinal Investigation into Supportive and Ancillary health services (LISA) study and completed a cross-sectional survey on their HIV-care experiences and healthcare engagement. The sample generally reflects an under-served population of PLWH. A linkage to the provincial Vital Statistics registry is used in this analysis in order to examine overall mortality and cause-specific mortality trends; probability of death was modeled using logistic regression for participants with ongoing clinical monitoring (n = 910)., Results: By June 2017, 208 (20.8%) participants had died. The majority of deaths 57 (27.4%) were attributed to drug-related complications or overdoses, 39 (18.8%) were attributed to HIV-related complications, and 36 (17.3%) to non-AIDS-defining malignancies. We observed elevated odds of death among PLWH who smoked tobacco (aOR: 2.11, 95% CI: 1.38, 3.23), were older (aOR: 1.06 per one-year increase, 95% CI: 1.04, 1.08), indicated heavy alcohol consumption (aOR: 1.57, 95% CI: 1.11, 2.22), and reported unstable housing (aOR: 1.96, 95% CI: 1.37, 2.80); while higher CD4 cell count was protective (aOR: 0.87 per 100-unit increase, 95% CI: 0.79, 0.94) as was male gender), though non-significant (aOR: 0.73, 95% CI: 0.49, 1.07)., Conclusions: Overdose is - the leading cause of mortality among a cohort of under-served PLWH in BC, Canada. Public health efforts to end the HIV epidemic and support the health and well-being of PLWH are being thwarted by persistent health inequities and the enormous and persistent risks facing people who use drugs. Integrated low-barrier primary care is essential for supporting under-served PLWH, and safe drug supply is needed to support PLWH who use drugs.

Objectives: Psychological stress is an important determinant of health, including for mental well-being and sexual health. However, little is known about the prevalence and psychosocial and sexual health correlates of perceived stress among young people in South Africa, where elevated life-stressors are an important driver of health inequities. This study examines the association between intimate partner violence (IPV), psychosocial and sexual health, and perceived stress, by gender, among South African adolescents and young adults. Methods: Using baseline survey data from AYAZAZI, a cohort study enrolling youth (16-24 years) from Durban and Soweto, we used the 10-item Perceived Stress Scale (PSS-10) to measure the degree to which an individual perceives their life situations as unpredictable, uncontrollable, and overloaded. Possible scores range between 0 and 40; higher scores indicating higher perceived stress. Crude and adjusted gender-stratified linear regression models examined associations between sexual health factors, experiences (young women) and perpetration (young men) of IPV, anxiety (APA 3-item Scale, ≥2 = probable anxiety), and depression (10-item CES-D Scale, ≥10 = probable depression) and perceived stress. Multivariable models adjusted for age, income, sexual orientation, and financial dependents. Results: Of the 425 AYAZAZI participants, 60% were young women. At baseline, 71.5% were students//learners and 77.2% earned ≤ ZAR1600 per month (~$100 USD). The PSS-10 had moderate reliability (α = 0.70 for young women, 0.64 for young men). Young women reported significantly higher mean PSS scores than young men [18.3 (6.3) vs. 16.4 (6.0)]. In adjusted linear regression models, among young women experiences of IPV (β = 4.33; 95% CI: 1.9, 6.8), probable depression (β = 6.63; 95% CI: 5.2, 8.1), and probable anxiety (β = 5.2; 95% CI: 3.6, 6.8) were significantly associated with higher PSS scores. Among young men, ever perpetrating IPV (β = 2.95; 95% CI: 0.3, 5.6), probable depression (β = 6; 95% CI: 4.3, 7.6), and probable anxiety (β = 3.9; 95% CI: 2.1, 5.8) were significantly associated with higher perceived stress. Conclusion: We found that probable depression, anxiety, perpetration of IPV among young men, and experiences of IPV among young women, were associated with higher perceived stress. Critical efforts are needed to address the gendered stressors of young men and women and implement services to address mental health within violence prevention efforts., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Pakhomova, Dietrich, Closson, Smit, Hornschuh, Smith, Beksinska, Ndung'u, Brockman, Gray and Kaida.)

Social isolation, a risk factor for poor health within the general population, may be exacerbated by unique challenges faced by people living with HIV (PLHIV). This analysis examines the association between social isolation and all-cause mortality among a cohort of PLHIV experiencing multiple social vulnerabilities. The analytical sample included 936 PLHIV ≥ 19 years, living in British Columbia, Canada, and enrolled in the Longitudinal Investigation into Supportive and Ancillary Health Services (LISA) Study (2007-2010). Participants were classified as Socially Connected (SC), Minimally Isolated (MI) or Socially Isolated (SI) via latent class analysis. Cross-sectional survey data was linked to longitudinal clinical data from a provincial HIV treatment database. Mortality was assessed longitudinally up to and including December 31st, 2017. Through multivariable logistic regression, an association between SI and all-cause mortality was found (adjusted OR: 1.48; 95% CI 1.08, 2.01). These findings emphasize the need to mitigate effects of social isolation among PLHIV.

Background: The ubiquity of cellular phone (cellphone) use in young people's daily lives has emerged as a priority area of concern for youth mental health., Objective: This study measured the prevalence of depression and its association with high cellphone use among youth in Soweto and Durban, South Africa., Methods: We analysed cross-sectional, baseline survey data among youth aged 16-24 who participated in a dual-site cohort study, 'AYAZAZI', conducted from 2014 to 2017. The primary outcome was depression using the 10-item Center for Epidemiologic Studies Depression Scale, with a score of ≥ 10 indicating probable depression. Cellphone use was measured via self-reported average number of hours of active use, with 'high cellphone use' defined as daily usage of ≥ 8. Multivariable logistic regression models assessed the independent relationship between high cellphone use and probable depression, adjusting for potential confounders., Results: Of 425 participants with a median age of 19 years (IQR = 18-21), 59.5% were young women. Overall, 43.3% had probable depression, with a higher prevalence among women (49.0% vs. 34.9%, P = .004). Nearly all (94.6%) owned a cellphone. About one-third (29.5%) reported spending ≥ 8 hours per day using their cellphone (39.3% of women vs. 14.9% of men, P < .001). In the overall adjusted model, youth reporting high daily cellphone use had higher odds of probable depression (aOR: 1.83, 95% CI: 1.16-2.90). In gender-stratified models, high daily cellphone use was associated with probable depression among women (aOR: 2.51, 95% CI: 1.47-4.31), but not among men (aOR: 0.87, 95% CI: 0.35-2.16)., Conclusions: Among a cohort of South African youth, we found a high prevalence of probable depression and high cellphone use (30%). The findings indicate a need for intersectoral initiatives focused on meaningful mental health support for South African youth to support positive growth and development.

Background: Current human papillomavirus (HPV) vaccine coverage in the United States (in 2019, 66-70%), remains below the Healthy People 2020 coverage goal of 80%. HPV vaccine misinformation, including parental concerns of sexual risk-compensation influence vaccine uptake. We examined the association between HPV vaccination and sexually transmitted infection (STI) outcomes., Methods: Of the 20,146 participants from 2013 to 2014 and 2015-2016 cycles of the National Health and Nutrition Examination Survey, 1050 females aged 18-35 with a history of sexual activity had complete case data. Roa-Scott Chi-squared and F-tests assessed survey-weighted socio-demographic differences between vaccinated and unvaccinated participants. Weighted logistic regression assessed crude and adjusted associations between self-reported HPV vaccination (none vs. ≥ 1dose) and lab-confirmed STIs (trichomonas and chlamydia) and vaccine-type HPV (6/11/16/18). As a sensitivity analysis, we conducted weighted-propensity score (PS) models and inverse probability weighting by vaccination status. PS and logistic regression were estimated through survey-weighted logistic regression on variables including race, education, income, marital status, US citizenship, cycle year and age., Results: Overall, 325 (31.8%) females with a history of sexual activity were HPV vaccinated, of which 22 (6.1%) received the vaccine at the routine-recommended ages of 11-12, 65.7% were vaccinated after their self-reported sexual debut, 3.8% had a lab-confirmed STI and 3.5% had vaccine-type HPV. There was no association between HPV vaccination and any STIs (adjusted odds ratio [aOR] 0.67, 95%CI:0.38-1.20), and vaccinated participants had 61% reduced odds of vaccine-type HPV (vs. unvaccinated; aOR 0.39, 95%CI:0.19-0.83). Results from the PS sensitivity analysis were similar to the main findings., Conclusion: Among females who reported a history of sexual activity, HPV vaccination status was protective against vaccine-type HPV and not associated with lab-based STI outcomes. Although findings may be susceptible to reporting bias, results indicating low vaccine uptake at routine-recommended ages requires additional efforts promoting HPV vaccination before sexual-debut., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Over the past three years, MEK has received consulting fees from Biogen Inc.

The use of biologic-based therapeutics has revolutionized our ability to treat complex diseases such as cancer- and autoimmune-related disorders. Biologic-based therapeutics are known to generate anti-drug immune responses or immunogenicity in clinical patients which can lead to altered pharmacokinetics, decreased drug efficacy, and unwanted adverse clinical events. Assays designed to detect and assess anti-drug immune responses are used to help monitor patients and improve drug safety. Utilizing a tiered approach, screening assays are developed first to identify patients that are potentially positive for anti-drug-specific antibodies. Patients that screen positive are subjected to additional tiers of testing that include a confirmation assay to confirm the presence of expected anti-drug-specific antibodies, a titer assay to assess relative levels of anti-drug-specific antibodies, and, depending on the drug's mechanism of action or concerns of adverse clinical reactions, further characterization such as drug neutralization and anti-drug antibody isotyping. This tiered approach can prove to be detrimental to clinical samples from exposure to multiple cycles of testing, freeze thaws, and repeated handling by lab personnel. Multiplexing some of these assays together may streamline the characterization of anti-drug immune responses and help reduce the repeated usage of clinical samples. In this study, we combined a screening assay and anti-drug isotyping assays into one multiplexed assay using the Luminex® xMAP® Technology. The multiplexed assay was developed and validated to meet the FDA recommended guidelines for immunogenicity assessments. These results show that multiplexed assays perform comparably to industry standards. This study should encourage labs to explore the use of multiplexing immunogenicity assays to characterize anti-drug antibody responses quickly, with less repeat testing and reduced sample handling.

Objective: To examine the independent association between intimate partner violence (IPV) severity and all-cause mortality among women living with HIV (WLHIV)., Design: Cross-sectional questionnaire linked to longitudinal vital statistics data., Methods: We examined the lifetime prevalence of IPV and age-standardized all-cause mortality rates by IPV severity reported by WLHIV. Lifetime IPV (emotional/verbal, physical, or sexual) severity was assessed as a categorical variable: no history of any IPV (none); experienced one or two forms of IPV (moderate); or experienced all three forms of IPV (severe IPV). Two separate logistic regression models examined associations between any IPV (vs. none) as well as IPV severity (none vs. moderate, severe) and all-cause mortality., Results: At the time of interview (2007-2010), 260 participants self-identified as women with a median (Q1-Q3) age of 41 years (35-46). Of these women, the majority were unemployed (85%), 59% reported any IPV and 24% reported severe IPV. Of the 252 women followed until 31 December 2017, 25% (n = 63) died. Age-standardized all-cause mortality rates for WLHIV who experienced severe IPV were two-times higher than women with no history of IPV (44.7 per 1000 woman-years vs. 20.9 per 1000 woman-years). After adjustment for confounding, experiences of severe IPV (vs. none) were significantly associated with all-cause mortality (aOR = 2.42, 95% CI = 1.03-5.70)., Conclusion: Although we found that any lifetime experience of IPV was not associated with all-cause mortality, women ever experiencing severe IPV were significantly more likely to die during the study period. This may suggest a need for increased trauma- and violence-aware approaches.

Background: Due to stigma and discrimination, gay, bisexual and other men who have sex with men (gbMSM) potentially carry a heightened burden of loneliness. This analysis investigates loneliness among gbMSM and its relationship with self-rated physical health, along with the mediating effect of depression., Methods: Participants were recruited using respondent-driven sampling into the Momentum Health Study (February 2012-February 2015) with follow-up visits occurring every 6 months till February 2018. Using computer-assisted self-interviews, measures of loneliness were assessed using a 6-item Loneliness Scale for Emotional and Social Loneliness (lonely vs not lonely). Current physical health was self-assessed (poor, fair, good, very good or excellent). A multivariable generalised linear-mixed model with a logit link function was used to examine the relationship between loneliness and self-rated physical health. We further investigated the mediating effect of depressive symptomatology on this relationship via the Hospital Anxiety and Depression Scale., Results: Of the 770 participants included, we found that 61% (n=471) experienced loneliness at baseline. Of the 674 (88%) who reported good/very good/excellent physical health, 59% (n=391) reported loneliness, compared with 87% (n=80) of those in poor/fair self-rated physical health who reported feeling lonely. After adjustment for confounding, loneliness was associated with poor self-rated physical health (adjusted OR 1.71; 95% CI 1.13 to 2.60). Depressive symptomatology was found to partially mediate this relationship., Conclusion: There may be a need for the integration of social, mental and physical health programming, targeted towards gbMSM, to alleviate the degree of loneliness experienced and its co-occurrence with poor self-rated physical health., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Partner notification and treatment are essential components of sexually transmitted infection (STI) management, but little is known about such practices among adolescents and young adults. Using data from a prospective cohort study (AYAZAZI) of youth aged 16-24 years in Durban, South Africa, we assessed the STI care cascade across participant diagnosis, STI treatment, partner notification, and partner treatment; index recurrent STI and associated factors; and reasons for not notifying partner of STI. Participants completed laboratory-based STI screening ( Chlamydia trachomatis, Neisseria gonorrhoeae , Mycoplasma genitalium , Trichomonas vaginalis ) at enrollment and at 12 months. Of the 37/216 participants with STI (17%), 27/37 (73%) were women and 10/37 (27%) were men. Median age was 19 years (IQR: 18-20). Of the participants with STI, 23/37 (62%) completed a Treatment and Partner Tracing Survey within 6 months of diagnosis. All survey participants reported completing STI treatment (100%), 17/23 (74%) notified a partner, and 6/23 (35%) reported partner treatment. Overall, 4/23 (11%) participants had 12-month recurrent C. trachomatis infection, with no association with partner notification or treatment. Stigma and lack of STI knowledge were reasons for not notifying partner of STI. STI partner notification and treatment is a challenge among youth. Novel strategies are needed to overcome barriers along the STI care cascade.

Using data from the Comparison of Outcomes and Service Utilization Trends (COAST) study we examined factors associated with mood disorder diagnosis (MDD) among people living with HIV (PLHIV) and HIV-negative individuals in British Columbia, Canada. MDD cases were identified between 1998 and 2012 using International Classification of Disease 9 and 10 codes. A total of 491,796 individuals were included and 1552 (23.7%) and 60,097 (12.4%) cases of MDD were identified among the HIV-positive and HIV-negative populations, respectively. Results showed HIV status was associated with greater odds of MDD among men and lower odds among women. Among PLHIV, MDD was significantly associated with: identifying as gay, bisexual or other men who have sex with men compared to heterosexuals; higher viral load; history of injection drug use; and concurrent anxiety, dysthymia, and substance use disorders. Findings highlight the need for comprehensive and holistic HIV and mental health care.

Qualitative research suggests that men's inability to achieve dominant forms of masculinity may be related to HIV-risk behaviours and intimate partner violence (IPV) perpetration. Using clustered cross-sectional data, we assessed how young men's gender role conflict was associated with HIV-risk behaviours in urban informal settlements in KwaZulu-Natal, South Africa. Gender Role Conflict and Stress (GRC/S) was measured using a South African adaptation of the GRC/S scale comprising three sub-scales: subordination to women; restrictive emotionality; and success, power and competition. In random-effect models adjusting for socio-demographics, we tested the relationship with GRC/S sub-scales and sexual health behaviours (transactional sex, use of sex workers, ≥2 main partners and ≥2 casual/once off partners), and relationship practices (relationship satisfaction, relationship control, partnership type and perpetration of IPV). Overall, 449 young men (median age = 25, Q1, Q3 = 23-28) were included in the analysis. Higher GRC/S scores, denoting more GRC/S, were associated with increased relationship control and increased odds of having ≥2 casual or one-off partners and engaging in transactional sex. We found differences in associations between each sub-scale and sexual health and relationship practices, highlighting important implications for informing both theoretical understandings of masculinity and gender transformative efforts.

Objective: Our primary objective was to examine the syndemic effect of HIV/HCV co-infection and mental health disorders (MHD) on the acute care hospitalization rate among people living with HIV (PLW-HIV) in British Columbia, Canada. Secondarily, we aimed to characterize the longitudinal trends in the aforementioned rate, while controlling for the effect of several factors., Methods: In this retrospective cohort study, individuals were antiretroviral therapy-naïve, ≥ 18 years old, initiated treatment between 1 January 2000 and 31 December 2014, and were followed for at least 6 months until 31 December 2015 or last contact. The outcome was acute care hospitalization rate (every 6-month interval) per individual. The exposure was the interaction between HIV/HCV co-infection and MHD. Generalized non-linear mixed-effects models were built., Results: Of the 4046 individuals in the final analytical sample, 1597 (39%) were PLW-HIV without MHD, 606 (15%) were people living with HIV and HCV (PLW-HIV/HCV) without MHD, 988 (24%) were PLW-HIV with MHD, and 855 (21%) were PLW-HIV/HCV with MHD. The adjusted rate ratios for acute care hospitalizations were 1.31 (95% [confidence interval] 1.13-1.52), 2.01 (95% CI 1.71-2.36), and 2.53 (95% CI 2.20-2.92) for PLW-HIV with MHD, PLW-HIV/HCV without MHD, and PLW-HIV/HCV with MHD, respectively, relative to PLW-HIV without MHD., Conclusion: The HIV/HCV co-infection and MHD interaction demonstrated a significant effect on the rate of acute care hospitalization, particularly for PLW-HIV/HCV with MHD. Implementing widely accessible integrative care model best practices may address this public health challenge.

Introduction: Measures used to assess equitable relationship dynamics, including the sexual relationship power scale (SRPS) have previously been associated with lower HIV-risk among young women, and reduced perpetration of intimate partner violence among men. However, few studies describe how the SRPS has been adapted and validated for use within global youth sexual health studies. We examined gender-specific psychometric properties, reliability, and validity of a SRPS used within a South African youth-engaged cohort study., Methods: Young men and women (16-24 years) enrolled in community-based cohorts in Durban and Soweto (2014-2016) reporting a primary partner at 6-month follow-up completed a 13-item (strongly agree/agree/disagree/strongly disagree) South African adaptation of Pulerwitz's SRPS (range 13-52, higher scores indicating greater sexual relationship power [SRP] equity). SRPS modifications were made using gender-specific exploratory factor analyses (EFAs), removing items with factor loadings <0.3. Cronbach alphas were conducted for full and modified scales by gender. Using modified scales, unadjusted and adjusted regression models examined associations between 1. relevant socio-demographic and relationship determinants and SRP equity, and 2. SRP equity and sexual relationship related outcomes. All models adjusted for education, age, site, and current employment., Results: 235 sexually-active youth (66% women, median age = 20) were included. Mean scores across all 13 scale items were 2.71 (SD 0.30) for women and 2.70 (SD 0.4) for men. Scale Cronbach's alphas were 0.63 for women and 0.64 for men. EFAs resulted in two gender-specific single-factor SRPS. Modified SRPS Cronbach alphas increased to 0.67 for women (8-items) and 0.70 for men (9-items). After adjusting for age, site and current employment, higher education remained associated with SRP equity across genders. In adjusted models, correlates of SRP equity included primary partnerships that were age-similar (<5 years older) and <2 years in length for women and living in Soweto and younger age for men. Greater SRP equity among women was also independently associated with no recent partner violence., Conclusions: Results highlight important gender differences in SRP equity measures and associations, highlighting the critically need for future research to examine gendered constructions of SRP equity in order to accurately develop, validate and use appropriate measures within quantitative surveys., Competing Interests: The authors have declared that no competing interests exist.

Schizophrenia is a severe mental illness with important implications for morbidity and mortality. This population-based cohort study examined the impact of schizophrenia diagnoses on all-cause mortality among a sample of people living with HIV (PLHIV) and a 10% random sample of individuals living without HIV (HIV-) in British Columbia (BC), through a data linkage between the BC Centre for Excellence in HIV/AIDS and Population Data BC's data holdings. Schizophrenia diagnoses were identified via International Classification of Diseases version 9 and version 10 codes. Age- and sex-adjusted all-cause mortality rates from January 1st, 1998 to December 31st, 2012 were calculated. Multivariable logistic models assessed (1) HIV status and mortality among individuals diagnosed with schizophrenia, (2) schizophrenia diagnosis and mortality among PLHIV, and (3) correlates of mortality among PLHIV concurrently diagnosed with schizophrenia (HIV+/SZO+). From 1998 to 2012, 6.3% of those with HIV had a schizophrenia diagnosis, compared to 1.1% of those without HIV. While significant declines in mortality rates were observed throughout the study period, mortality rates were highest among HIV+/SZO+. After adjustment for substance use disorder and age at baseline, HIV+/SZO+ had a 2.64 times greater odds of mortality (95% confidence interval [CI] = 2.14-3.25) compared to HIV-/SZO+. For PLHIV, a schizophrenia diagnosis was not associated with mortality after controlling for potential confounders (adjusted odds ratio [aOR] = 0.90, 95%CI = 0.74-1.09). Among HIV+/SZO+, age, history of injection drug use, ever having an AIDS-defining illness, and never being on anti-psychotic medication or accessing psychiatric services were associated with mortality. Efforts should be made to identify and link to care individuals disproportionately affected by schizophrenia and excess mortality, including those living with HIV., (Copyright © 2019 Elsevier B.V.

Background: Young gay, bisexual, and other men who have sex with men (YGBM) may have reduced engagement and knowledge of HIV care and biomedical HIV prevention strategies, such as pre-exposure prophylaxis (PrEP), post-exposure prophylaxis (PEP), and Treatment as Prevention (TasP), compared with adult GBM. We sought to understand differences in HIV prevention awareness, health care access, and service utilization between youth (16-29 years) and adult (≥30 year) GBM, as well as factors associated with attendance in HIV leadership programming among YGBM living in the publicly funded PrEP setting of Vancouver, Canada., Methods: Sexually-active GBM were recruited using respondent-driven sampling (RDS) from February 2012 to February 2015. Participants completed an in-person computer-assisted self-interview every 6 months, up to February 2017, with questions on sociodemographic factors, awareness of biomedical HIV prevention strategies, and an HIV treatment optimism-skepticism scale. Participants were asked if they had ever attended either of two HIV-leadership programs designed for YGBM. Both programs involve multiple GBM-led education and social networking sessions operated by community-based organizations in Vancouver. Multivariable Glimmix confounder models assessed differences between youth and adult GBM. Among younger men, bivariate analyses examined factors associated with HIV-leadership program attendance., Results: Of 698 GBM who enrolled in the longitudinal study, 36.8% were less than 30 years old at the first study visit. After controlling for gender identification, sexual orientation, HIV status, and income in the past 6 months, younger GBM (n = 257/698) had lower awareness of biomedical HIV prevention strategies and less HIV treatment optimism compared with older GBM (n = 441/698). Among younger GBM who attended HIV-leadership programs (n = 50), greater awareness of biomedical HIV prevention strategies and higher HIV treatment optimism were reported, compared with non-attendees., Conclusion: Younger GBM, who are disproportionately affected by the HIV epidemic, are less aware of new prevention technologies than older GBM, but attending peer-based HIV-leadership programs ameliorates age-disparities in HIV-prevention knowledge and treatment optimism.

Purpose: We assessed differences in optimal adherence between youth (aged 15-29 years) and adults (aged ≥30 years) enrolled in the British Columbia Centre for Excellence in HIV/AIDS Drug Treatment Program from 2010 to 2016., Methods: Population-level clinical data were used to compare optimal antiretroviral therapy adherence (≥95%), based on pharmacy refill data, among youth and adults. Unadjusted and adjusted generalized estimating estimates were performed to examine the independent relationship between time-dependent age categories and optimal adherence, adjusting for confounders. Factors associated with optimal adherence among youth were examined., Results: Data for 7,485 individuals living with HIV were included. Median follow-up was 7 years (Q1-Q3: 4-7). Over the study period, the number of individuals categorized as "youth" ranged from 820 in 2010 to 291 in 2016. Multivariable models found youth living with HIV were significantly less likely to be optimally adherent than adults (adjusted odds ratio [aOR] = .55; 95% confidence interval [CI]: .49-.62), after controlling for potential confounders, although youth adherence improved significantly during the study period. Among youth, increasing time-dependent age (aOR = 1.18/year older; 95%CI: 1.11-1.25) and number of years on antiretroviral therapy (aOR = 1.15, 95%CI: 1.10-1.19) were independently associated with optimal adherence, while Hepatitis C-positive serostatus (aOR = .55; 95%CI: .33-.92) and multiple treatment regimen change (aOR = .89/regimen change; 95%CI: .81-.97) were negatively associated with optimal adherence., Conclusions: Youth were less likely to be optimally adherent throughout the study period. Findings suggest implications for increased youth-centered adherence support, particularly for youth living with HIV concurrently living with Hepatitis C, newly initiating treatment, and going through medication change., (Copyright © 2018.

Objectives: To assess the impact of physicians' patient base composition on all-cause mortality among people living with HIV (PLHIV) who initiated highly active antiretroviral therapy (HAART) in British Columbia (BC), Canada., Design: Observational cohort study from 1 January 2000 to 31 December 2013., Setting: BC Centre for Excellence in HIV/AIDS' (BC-CfE) Drug Treatment Program, where HAART is available at no cost., Participants: PLHIV aged ≥ 19 who initiated HAART in BC in the HAART Observational Medical Evaluation and Research (HOMER) Study., Outcome Measures: All-cause mortality as determined through monthly linkages to the BC Vital Statistics Agency., Statistical Analysis: We examined the relationships between patient characteristics, physicians' patient base composition, the location of the practice, and physicians' experience with PLHIV and all-cause mortality using unadjusted and adjusted Cox proportional hazards models., Results: A total of 4 445 PLHIV (median age = 42, Q1, Q3 = 34-49; 80% male) were eligible for our study. Patients were seen by 683 prescribing physicians with a median experience of 77 previously treated PLHIV in the past 2 years (Q1, Q3 = 23-170). A multivariable Cox model indicated that the following factors were associated with all-cause mortality: age (aHR = 1.05 per 1-year increase, 95% CI = 1.04 to 1.06), year of HAART initiation (2004-2007: aHR = 0.65, 95% CI = 0.53 to 0.81, 2008-2011: aHR = 0.46, 95% CI = 0.35 to 0.61, Ref: 2000-2003), CD4 cell count at baseline (aHR = 0.88 per 100-unit increase in cells/mm 3 , 95% CI = 0.82 to 0.94), and < 95% adherence in first year on HAART (aHR = 2.28, 95% CI = 1.88 to 2.76). In addition, physicians' patient base composition, specifically, the proportion of patients who have a history of injection drug use (aHR = 1.11 per 10% increase in the proportion of patients, 95% CI = 1.07 to 1.15) or Indigenous ancestry (aHR = 1.07 per 10% increase , 95% CI = 1.03-1.11) and being a patient of a physician who primarily serves individuals outside of the Vancouver Coastal Health Authority region (aHR = 1.22, 95% CI = 1.01 to 1.47) were associated with mortality., Conclusions: Our findings suggest that physicians with a higher proportion of individuals who face potential barriers to care may need additional supports to decrease mortality among their patients. Future research is required to examine these relationships in other settings and to determine strategies that may mitigate the associations between the composition of physicians' patient bases and survival., Competing Interests: Competing interests: VDL is funded by a grant from the Canadian Institutes of Health Research (PJT-148595), by a Scholar Award from the Michael Smith Foundation for Health Research and a New Investigator Award from the Canadian Institutes of Health Research.

Background In the USA, young Black gay, bisexual or other men who have sex with men (YBMSM) bear the largest burden of HIV incidence. The aim of this study is to examine the independent associations between economic dependency on a sexual partner and several HIV risk behaviours and sexual health outcomes among YBMSM living in Jackson, Mississippi, USA., Methods: Baseline data from 589 YBMSM, with a median age of 22.0 years (IQR=15-25) participating in a brief sex-positive HIV and STI prevention intervention, were used to measure the association between six sexual behaviours, sexually transmissible infections (STIs) status at baseline and economic dependence. Bivariate χ2 associations were tested and regression models adjusted for education level (≤ high school), employment and HIV-status., Results: In regressions, of the six sexual behaviours reported in the last 90 days and six STIs tested at baseline, economically dependent YBMSM were more likely to report condomless anal receptive sex (aOR=2.19, 95%CI=1.25-3.83), ≥3 partners as a top (aOR=1.99, 95%CI=1.17-340), ≥3 sex partners as a bottom (aOR=2.07, 95%CI=1.24-3.45), ≥3 sex acts as a bottom (aOR=2.10, 95%CI=1.16-3.82) and testing positive for oral gonorrhoea (aOR=2.39, 95%CI=1.18-4.83) after controlling for HIV status, employment and education., Conclusions: Interventions should consider how poverty, unemployment and economic dependence interact to influence relationship power imbalances, condom use and sexual positioning agency, and sexual health for key populations of MSM.
