BackgroundConsistent with young adults’ penchant for digital communication, young adults living with HIV use digital communication media to seek out health information. Understanding the types of health information sought online and the characteristics of these information-seeking young adults is vital when designing digital health interventions for them. ObjectiveThis study aims to describe characteristics of young adults living with HIV who seek health information through the internet. Results will be relevant to digital health interventions and patient education. MethodsYoung adults with HIV (aged 18-34 years) self-reported internet use during an evaluation of digital HIV care interventions across 10 demonstration projects in the United States (N=716). Lasso (least absolute shrinkage and selection operator) models were used to select characteristics that predicted whether participants reported seeking general health and sexual and reproductive health (SRH) information on the internet during the past 6 months. ResultsAlmost a third (211/716, 29.5%) and a fifth (155/716, 21.6%) of participants reported searching for general health and SRH information, respectively; 26.7% (36/135) of transgender young adults with HIV searched for gender-affirming care topics. Areas under the curve (>0.70) indicated success in building models to predict internet health information seeking. Consistent with prior studies, higher education and income predicted health information seeking. Higher self-reported antiretroviral therapy adherence, substance use, and not reporting transgender gender identity also predicted health information seeking. Reporting a sexual orientation other than gay, lesbian, bisexual, or straight predicted SRH information seeking. ConclusionsYoung adults living with HIV commonly seek both general health and SRH information online, particularly those exploring their sexual identity. Providers should discuss the most commonly sought SRH topics and the use of digital technology and be open to discussing information found online to better assist young adults with HIV in finding accurate information. Characteristics associated with health information–seeking behavior may also be used to develop and tailor digital health interventions for these young adults.

BackgroundTransgender youth demonstrate significantly higher rates of engagement in sexual risk behaviors relative to their cisgender or gender-conforming counterparts, including high rates of condomless anal intercourse and engagement in sex work. In addition, transgender youth experience increased physical or sexual abuse, victimization, substance use, mental health disorders, incarceration, and homelessness. Owing to these syndemic health disparities, transgender youth are at substantially increased risk of HIV infection. ObjectiveThis protocol aims to describe a randomized controlled trial (RCT), Adolescent Medicine Trials Network 160 TechStep (N=250), which assesses the differential immediate and sustained effects of each of 3 conditions (text messaging, WebApp, or information-only control) for reducing sexual risk behaviors and increasing pre-exposure prophylaxis (PrEP) uptake among high-risk, HIV-negative transgender youth and young adults (aged 15-24 years). MethodsParticipants will be recruited through web-based (targeted social media sites and apps) and offline (print ads and flyers) advertisements, peer and clinic referrals, and street- and venue-based outreach, and by contacting potential participants who have requested contact for future studies. Participants will be randomized into 1 of the 3 conditions: (1) text messaging, (2) WebApp, or (3) information-only control for 6 months. Assessments will occur at baseline and at 3, 6, and 9 months. Participants who do not show improvements in sexual risk or PrEP uptake at the 3-month assessment will be rerandomized to receive weekly electronic coaching (eCoaching) sessions in addition to their assigned text messaging or WebApp intervention, or remain in the original text messaging or WebApp intervention using a 2:1 ratio. Participants originally assigned to the information-only condition are not eligible for rerandomization. ResultsFunding for TechStep was awarded in June 2017. Phase 1 was approved by the Institutional Review Board (IRB) in April 2018. Recruitment began in November 2018 for phase 1, the formative phase. Initial phase 2 IRB approval came in June 2019. The data collection for phase 2, the RCT, is expected to be completed in April 2021. As of March 2020, 54 participants have been enrolled in TechStep. The final results are anticipated in May 2021. ConclusionsBy providing culturally responsive, technology-based interventions, TechStep aims to improve sexual health outcomes among HIV-negative transgender youth and young adults at high risk of HIV. TechStep will evaluate the efficacy of technology-based interventions for reducing HIV sexual risk behaviors and increasing PrEP initiation, adherence, and persistence. The suite of technology-based interventions developed in TechStep, and assessed for efficacy in a 3-condition RCT, represents an important advancement in intervention science toward developing tailored and scalable interventions for transgender youth and young adults.

BackgroundYoung people are disproportionately impacted by HIV infection and exhibit poor HIV care continuum outcomes. Mobile health (mHealth) interventions are promising approaches to meet the unique needs of young people living with HIV. Youth-focused interventions are needed to improve HIV care continuum outcomes. ObjectiveThis study assessed the preliminary efficacy and impact of a digital HIV care navigation intervention among young people living with HIV in San Francisco. Health electronic navigation (eNavigation or eNav) is a 6-month, text message–based, digital HIV care navigation intervention, in which young people living with HIV are connected to their own HIV care navigator through text messaging to improve engagement in HIV primary care. MethodsThis study had a single-arm, prospective, pre-post design. The analysis included 120 young men who have sex with men or transwomen living with HIV aged between 18 and 34 years. We analyzed self-reported sociobehavioral information pre- and postintervention at baseline and 6 months, which was collected using computer-assisted self-interviewing surveys. We characterized the sample and built generalized estimating equation (GEE) models to assess differences in HIV care continuum outcomes at baseline and 6 months. ResultsThe characteristics according to the intervention completion status were not different from those of the overall sample. The mean age of the participants was 27.75 years (SD 4.07). Most participants (103/120, 85.8%) identified as men, and the sample was racially/ethnically diverse. At baseline, majority (99/120, 82.5%) of the participants had recently received primary HIV care, yet this was more likely in those who completed the intervention than in those who did not (54/60, 90% vs 45/60, 75%; χ21=4.68, P=.03). More than half of the sample reported taking antiretroviral therapy (92/120, 76.7%) and having an undetectable viral load (65/120, 54.2%). The 6-month follow-up surveys were completed by 73.3% (88/120) of participants, and these participants were not characteristically different from the overall sample at baseline. GEE models indicated that participants had increased odds of viral suppression at 6 months as compared with baseline. No relevant additive or multiplicative interactions were noted on comparing outcome effects over time according to intervention completion. ConclusionsDigital HIV care navigation fills a critical gap in public health and HIV care systems, making these systems more responsive and accountable to the needs of the most vulnerable individuals. Our intervention bridges the time between primary care visits with interactive, tailored, personalized, and peer-delivered social support; information; and motivational interviewing to scaffold behavioral change. This study is part of the next wave of system-informed mHealth intervention research that will offer potentially disruptive solutions to traditional in-person delivered interventions and improve the health of the most vulnerable individuals.

BackgroundHIV continues to be a public health challenge adversely affecting youth and young adults, as they are the fastest-growing group of new HIV infections in the United States and the group with the poorest health outcomes among those living with HIV. HIV prevention science has turned to mobile health as a novel approach to reach and engage young people living with HIV (YPLWH) experiencing barriers to HIV care. ObjectiveThis study aimed to assess the feasibility and acceptability of a text message–based HIV care navigation intervention for YPLWH in San Francisco. Health eNavigation is a 6-month text message–based HIV care navigation where YPLWH are connected to their own HIV care navigator through text messaging to improve engagement in HIV primary care. Digital HIV care navigation included delivery of the following through SMS text messaging: (1) HIV care navigation, (2) health promotion and education, (3) motivational interviewing, and (4) social support. MethodsWe evaluated the feasibility and acceptability of a text message–based HIV care navigation intervention among YPLWH. We assessed feasibility using quantitative data for the overall sample (N=120) to describe participant text messaging activity during the intervention. Acceptability was assessed through semistructured, in-depth interviews with a subsample of 16 participants 12 months after enrollment. Interviews were audio-recorded, transcribed, and analyzed using grounded theory. ResultsOverall, the text message–based HIV care navigation intervention was feasible and acceptable. The majority of participants exhibited medium or high levels of engagement (50/120 [41.7%] and 26/120 [21.7%], respectively). Of the majority of participants who were newly diagnosed with HIV, 63% (24/38) had medium to high engagement. Similarly, among those who were not newly diagnosed, 63% (52/82) had medium to high engagement. The majority of participants found that the intervention added value to their lives and improved their engagement in HIV care, medication adherence, and viral suppression. ConclusionsText message–based HIV care navigation is a potentially powerful tool that may help bridge the gaps for linkage and retention and improve overall engagement in HIV care for many YPLWH. Our results indicate that participation in text message–based HIV care navigation is both feasible and acceptable across pervasive structural barriers that would otherwise hinder intervention engagement.

BackgroundYoung racial and ethnic minority men who have sex with men (MSM) and trans women are disproportionately affected by HIV and AIDS in the United States. Unrecognized infection, due to a low uptake of HIV testing, and poor linkage to care are driving forces of ongoing HIV transmission among young racial and ethnic minority MSM and trans women. Internet and mobile technologies, in combination with social network-based approaches, offer great potential to overcome and address barriers to care and effectively disseminate interventions. ObjectiveWe describe Health eNavigation (Health eNav), a digital HIV care navigation intervention that extends supportive care structures beyond clinic walls to serve youth and young adults living with HIV who are newly diagnosed, not linked to care, out of care, and not virally suppressed, at times when they need support the most. MethodsThis study leverages ecological momentary assessments for a period of 90 days and uses person-delivered short message service text messages to provide participants with digital HIV care navigation over a 6-month period. We aim to improve engagement, linkage, and retention in HIV care and improve viral suppression. Digital HIV care navigation includes the following components: (1) HIV care navigation, (2) health promotion, (3) motivational interviewing, and (4) digital social support. ResultsRecruitment began on November 18, 2016; enrollment closed on May 31, 2018. Intervention delivery ended on November 30, 2018, and follow-up evaluations concluded on October 31, 2019. In this paper, we present baseline sample characteristics. ConclusionsWe discuss real-world strategies and challenges in delivering the digital HIV care navigation intervention in a city-level, public health setting.

BackgroundEcological momentary assessments (EMAs) administered via text messaging facilitate real-time data collection. With widespread cell phone access, EMAs are becoming more available to even the most disenfranchised communities, such as those living with HIV. However, structural barriers disproportionately burden young men who have sex with men (MSM) and trans women (TW) living with HIV and threaten participation in HIV research. ObjectiveWe aim to identify structural barriers to completing EMA text surveys nested within a digital HIV care intervention for young MSM and TW living with HIV in San Francisco. MethodsA total of 10,800 EMA text messages were delivered daily over 90 days to 120 participants enrolled in the Health eNav intervention (2017-2018) at the San Francisco Department of Public Health. EMA surveys inquired about participants’ daily affect, sexual behaviors, substance use, and treatment adherence. Survey completion was calculated after 30, 60, and 90 days of follow-up. We described characteristics of nonstarters (those who provided less than four complete responses to the first seven EMA surveys) and analyzed structural correlates of days to first weeklong or more EMA survey noncompletion using multivariable Cox proportional hazards regression. Qualitative interviews were used to evaluate the acceptability of EMA surveys. ResultsParticipants completed 4384 of 10,800 (40.59%) EMA surveys. Completion of 70% or more of EMA surveys was attained by 56 of 120 participants (46.7%) at 30 days of follow-up, 40/120 (33.3%) at 60 days of follow-up, and 30/120 (25.0%) by the end of the 90-day study period. Twenty-eight participants (23.3%) were identified as nonstarters, and were more likely to be recently incarcerated (prevalence ratio [PR] 2.3, 95% CI 1.3-4.4), forego basic needs for HIV medications (PR 2.4, 95% CI 1.3-4.5), and be diagnosed with HIV in the last year (PR 2.2, 95% CI 1.1-4.1). Adjusting for nonstarters, young MSM and TW living in temporary/transitional housing (adjusted hazard ratio [aHR] 1.8, 95% CI 1.1-3.0), foregoing HIV medications to afford basic needs (aHR 1.7, 95% CI 1.1-2.7), and having less than a college education (aHR 3.5, 95% CI 1.4-9.0) had greater hazard of weeklong or more EMA survey noncompletion. Overall, there was high acceptability of the EMA surveys. ConclusionsAlthough access to and use of technology is increasingly ubiquitous, this analysis demonstrates persisting gaps in EMA completion by socioeconomic factors such as incarceration, education level, housing, and competing needs for young MSM and TW living with HIV in San Francisco. Moreover, those recently diagnosed with HIV were more likely to experience an immediate drop-off in completing EMA surveys. EMAs are feasible for individuals not experiencing social inequity and structural barriers. HIV prevention technologies addressing these barriers and leveraging similar methodology may prove effective for young MSM and TW living with HIV.

Stigma towards trans women in Nepal creates individual and system-level risks for HIV. A critical protective factor is access to HIV prevention. Research is needed to determine the impact of stigma on HIV testing among trans women in Nepal. We conducted a secondary analysis of data collected using respondent driven sampling in 2019 on HIV risk among trans women in Nepal. Data analysis was restricted to trans women who were HIV negative at testing through the parent study. Descriptive statistics, tests for bivariable associations between HIV testing and stigma variables, and binomial Poisson regression were conducted to examine HIV testing outcomes. There were 173 participants who tested negative for HIV in our sample. The majority were under age 35 (59%) and most had a grade school education or less (64.7%). No trans women were homeless and most rented a room (70.5%) or owned their home (19.7%). The majority were currently sex workers (57.8%). Almost all HIV-negative trans women had ever been tested for HIV (90.8%), but only 53.5% in the last 3 months. The most frequently cited reason for not having been tested was thinking they were at low risk for HIV (40.9%) and being afraid of receiving a positive test result (22.7%). HIV and anti-trans stigma were high across most measures, including that almost all (94.2%) believed that most people in Nepal would discriminate against people with HIV. And most participants thought trans women were not accepted in Nepali Society (65.9%). Most participants also reported high social support (70.5%). Social cohesion among participants varied, with most experiencing medium (41.6%) or high (33.5%) social cohesion. Just over half had high social participation (55.5%). Participants who reported current sex work had lower prevalence of not testing for HIV in the last 3 months (prevalence ratio, PR = 0.54, 95% confidence interval, 95%CI = 0.32-0.92, p = 0.02). Every one-unit increase in social cohesion was associated with 1.05 times the prevalence of not testing for HIV in the last 3 months (95%CI = 1.01-1.09, p-value = 0.02). Trans women who did sex work were more likely to be HIV tested while those who were more socially connected to peers were less likely to have recently been tested for HIV. HIV stigma may result in fear of social rejection from peers if one tests positive. Interventions that focus on addressing stigma within trans women's social networks and strategies to mitigate HIV stigma in society may result in increased frequency of HIV testing among trans women in Nepal.

BackgroundTo determine if improvements in social determinants of health for trans women and decreases in transphobic discrimination and violence occurred over three study periods during which extensive local programs were implemented to specifically address longstanding inequities suffered by the transgender community.MethodsInterviewer-administered surveys from repeated cross-sectional Transwomen Empowered to Advance Community Health (TEACH) studies in 2010, 2013 and 2016-2017 in San Francisco collected experiences with transphobia violence and discrimination. Respondent-driven sampling was used to obtain a sample of participants who identified as a trans woman.ResultsViolence due to gender identity was prevalent; in each study period, verbal abuse or harassment was reported by over 83% of participants, and physical abuse or harassment was reported by over 56%. Adverse social determinants of health including homelessness, living below the poverty limit, methamphetamine use, depression, PTSD, and anxiety all significantly increased from 2010 to 2016. When testing for trends, housing discrimination and physical violence were both more likely in 2016-2017 compared to the two earlier study periods. Housing discrimination (aOR 1.41, 95% CI 1.00-1.98) and physical violence due to gender identity/presentation (aOR 1.39, 95% CI 1.00-1.92) both significantly increased from 2010 to 2016.ConclusionOur findings are particularly alarming during a period when significant public health resources and community-based initiatives specifically for trans women were implemented and could have reasonably led us to expect improvements. Despite these efforts, physical violence and housing discrimination among trans women worsened during the study periods. To ensure future improvements, research and interventions need to shift the focus and burden from trans people to cisgender people who are the perpetuators of anti-trans sentiment, stigma, discrimination and victimization.

Transgender women face a serious risk of HIV infection. Despite this, there is limited knowledge and use of Pre-exposure prophylaxis (PrEP). We measured the continuity of prevention across services in the PrEP cascade and correlates of PrEP use among trans women in San Francisco enrolled in the 2019/20 National HIV Behavioral Surveillance Study. Knowledge and use of PrEP among trans women in San Francisco increased in recent years; almost all (94.0%) had heard about PrEP, 64.7% had discussed PrEP with a healthcare provider, and 44.8% had taken PrEP in the past 12 months. PrEP use was associated with participation in a PrEP demonstration project (aOR = 31.44, p = 0.001) and condomless receptive anal intercourse (aOR = 3.63, p = 0.024). Injection drug use was negatively associated (aOR = 0.19, p = 0.014). Efforts are needed to combat the gender-based stigma and discrimination faced by trans women, which can result in avoidance and mistrust of the medical system.

BackgroundTransgender women (trans women) in Nepal are underserved in the HIV response. Data are needed to determine the HIV prevalence disaggregated from other key populations and to identify the particular risks faced by this community. Trans women are marginalized around the world and research is also needed to determine the impact of stigma on HIV risk to inform trans-specific interventions.MethodsIn 2019, we conducted the first population-based HIV behavioral surveillance study of trans women disaggregated from other key populations using respondent driven sampling (RDS). We estimated the HIV prevalence for trans women, and bivariate and multivariate Poisson binomial regression models were constructed to examine the relationship between HIV risk and stigma.ResultsTrans women participants (N = 200) had a mean age of 33 years old (SD = 10.96). We found a weighted HIV prevalence of 11.3% (95% CI 6·82% - 18·13). We found that depression and anxiety (aPR 0.81; 95% CI 0.67-0.97; p = 0·02) and current engagement in sex work (aPR 1.31; 95% CI 1.01-1.71; p = 0·046) were significantly associated with greater prevalence of condomless receptive anal intercourse. We found that experienced stigma of ever being verbally abused due to gender identity was significantly associated with lower prevalence of depression and anxiety (aPR 0.42; 95% CI 0.20-0.87; p = 0·002). Feeling unaccepted in Nepali society and believing people thought they were a criminal because of their trans identity was significantly associated greater prevalence of current sex work (aPR 1.36; 95% CI 1.03-1.78; p = 0·03; aPR 1.45; 95% CI 1.03-2.07; p = 0.04). Every measure of experienced stigma assessed was significantly associated with greater prevalence of current engagement in sex work.ConclusionsTrans women are highly stigmatized in Nepal, leading to individual and systems factors that impact their risk for HIV. Interventions are needed that support the economic and mental wellbeing of trans women to prevent their heighted risk of HIV from stigma.

BACKGROUND: Trans women experience high rates of gender-based violence (GBV)-a risk factor for adverse health outcomes. Transphobic hate crimes are one such form of GBV that affect trans women. However, little is understood about factors that shape transphobic hate crimes and racial/ethnic variation in these experiences. To contextualize GBV risk and police reporting, we examined self-reported types and correlates of transphobic hate crimes by racial/ethnic group of trans women in the San Francisco Bay Area. METHODS: From 2016 to 2018, trans women participated in a longitudinal cohort study of HIV. Secondary data analyses (N = 629) examined self-reported experiences of transphobic hate crimes (i.e., robbery, physical assault, sexual assault, and battery with weapon) by race/ethnicity, and whether hate crimes were reported to the police. Chi-square tests and simple logistic regression examined demographic, sociocultural, and gender identity factors associated with transphobic violence experiences and police reporting. RESULTS: About half (45.8%) of participants reported ever experiencing a transphobic hate crime; only 51.1% of these were reported to the police. Among those who reported a hate crime experience, Black (47.9%) and Latina (49.0%) trans women reported a higher prevalence of battery with a weapon; White (26.7%) and trans women of other race/ethnicities (25.0%) reported a higher prevalence of sexual assault (p = 0.001). Having ones gender questioned, history of sex work, homelessness as a child and adult, and a history incarceration were associated with higher odds of experiencing a transphobic hate crime. Trans women who felt their gender identity questioned had lower odds of reporting a hate crime to the police compared to those did not feel questioned. CONCLUSIONS: A high proportion of trans women experienced a transphobic hate crime, with significant socio-structural risk factors and racial differences by crime type. However, crimes were underreported to the police. Interventions that address structural factors, especially among trans women of color, can yield violence prevention benefits.

IntroductionAlthough transgender women (trans women) often are conflated with men who have sex with men  (MSM) in HIV research and services, there are distinct population differences that are important for implementing effective HIV prevention. Our objective was to examine pre-exposure prophylaxis (PrEP) disparities between the two populations and compare individual, social and structural factors that influence differences between MSM and trans women along the PrEP continuum.MethodsWe analysed data from two population-based studies, one with trans women (Trans*National Study, 2016 - 18) and the other with MSM (National HIV Behavioral Surveillance, 2017). Trans women were recruited via respondent-driven sampling and MSM using time location sampling. Key indicators of the PrEP continuum were evaluated, including awareness, health insurance, provider discussions, recent use and adherence. Associations were also examined for PrEP continuum indicators and structural barriers (e.g. employment, homelessness).ResultsTranswomen were more likely than MSM to be Latino/a (30.4% vs. 25.8%; prevalence ratio (PR)=1.08, 95% CI 1.02 to 1.14) or African American (7.1% vs. 4.5%; PR = 1.12, 1.02 to 1.24), live at or below the poverty limit (70.7% vs. 15.8%; PR = 1.47; 1.41 to 1.53), be unemployed (50.1% vs. 26.3%; PR = 1.18, 1.13 to 1.24), be homeless (8.4% vs. 3.5%; PR = 1.15, 1.06 to 1.25) and to have less than a college degree (PR = 1.41, 1.34 to 1.48). Trans women were more likely than MSM to have health insurance (95.7% vs. 89.7%, PR = 1.17, 1.06 to 1.28), but less likely than MSM to have heard of PrEP (79.1% vs. 96.7%; PR = 0.77, 0.73 to 0.81), talked with a provider about PrEP (35.5% vs. 54.9%; PR = 0.87, 0.83 to 0.91) and less likely than MSM to have used PrEP in the past six months (14.6% vs. 39.8%; PR = 0.80, 0.76 to 0.84). Among PrEP users, trans women were less likely to report being adherent to PrEP than MSM (70.4% vs. 87.4%; PR = 0.80, 0.70 to 0.91).ConclusionsWe found PrEP disparities for trans women compared to MSM and the need for differentiated implementation strategies to meet the specific PrEP barriers trans women face. Inclusion of trans women's HIV risks is needed in CDC guidance for PrEP. Interventions to increase trans women's awareness of PrEP including at the provider and community level are also needed. Finally, programming that addresses trans women's barriers to housing and income is also needed to reduce PrEP disparities.

BACKGROUND Consistent with young adults’ penchant for digital communication, young adults living with HIV use digital communication media to seek out health information. Understanding the types of health information sought online and the characteristics of these information-seeking young adults is vital when designing digital health interventions for them. OBJECTIVE This study aims to describe characteristics of young adults living with HIV who seek health information through the internet. Results will be relevant to digital health interventions and patient education. METHODS Young adults with HIV (aged 18-34 years) self-reported internet use during an evaluation of digital HIV care interventions across 10 demonstration projects in the United States (N=716). Lasso (least absolute shrinkage and selection operator) models were used to select characteristics that predicted whether participants reported seeking general health and sexual and reproductive health (SRH) information on the internet during the past 6 months. RESULTS Almost a third (211/716, 29.5%) and a fifth (155/716, 21.6%) of participants reported searching for general health and SRH information, respectively; 26.7% (36/135) of transgender young adults with HIV searched for gender-affirming care topics. Areas under the curve (>0.70) indicated success in building models to predict internet health information seeking. Consistent with prior studies, higher education and income predicted health information seeking. Higher self-reported antiretroviral therapy adherence, substance use, and not reporting transgender gender identity also predicted health information seeking. Reporting a sexual orientation other than gay, lesbian, bisexual, or straight predicted SRH information seeking. CONCLUSIONS Young adults living with HIV commonly seek both general health and SRH information online, particularly those exploring their sexual identity. Providers should discuss the most commonly sought SRH topics and the use of digital technology and be open to discussing information found online to better assist young adults with HIV in finding accurate information. Characteristics associated with health information–seeking behavior may also be used to develop and tailor digital health interventions for these young adults.

PurposeYoung trans women (YTW) carry a disproportionate burden of HIV. The developmental context of HIV risk for YTW is underexamined. The aim of this analysis was to examine whether parent/caregiver responses to gender identity were associated with engagement in HIV-related sexual risk behavior for YTW and whether these associations varied by racial/ethnic identity or age.MethodsBaseline data from the SHINE study (n = 300) at San Francisco Department of Public Health (2012-2014) were analyzed. Multivariable Poisson binomial regression models characterized relationships between parent/caregiver responses to gender identity and HIV-related sexual risk behaviors, adjusting for select participant demographics. Statistically significant interactions (by race/ethnicity or age) were plotted using marginal predicted probabilities of sexual risk behaviors.ResultsThirty-seven percent of YTW engaged in any condomless anal intercourse; 12% reported income from sex work in the last month. Ever moving away from family and friends because of gender identity was associated with condomless anal intercourse (adjusted prevalence ratio [PR] = 1.44, 95% confidence interval [CI] = 1.08-1.92, p = .01) and sex work (PR = 2.07, 95% CI = 1.14-3.75, p=.02). Ever receiving poor treatment from parents/caregivers because of gender identity was associated with sex work (PR = 3.47, 95% CI = 1.52-7.95, p < .01). Greater parent/caregiver acceptance of gender identity was associated with lower adjusted prevalence of condomless anal intercourse for Hispanic/Latinx YTW.ConclusionsNegative parent/caregiver exposures related to YTW's gender identities were associated with increased HIV-related sexual risk behaviors, whereas parent/caregiver acceptance of gender identity was protective against condomless anal intercourse for Hispanic/Latinx YTW. There is a need for additional studies that inform interventions for YTW focusing on parent/caregiver relationships to prevent HIV-related risk behavior.

BackgroundTrans*female youth (TFY) carry a disproportionate burden of HIV. Few longitudinal studies have analyzed both proximal and upstream predictors of changes in HIV-related risk behaviors for TFY. The aim of the present analysis was to identify psychosocial predictors of changes in sexual risk behavior over time for TFY in the San Francisco Bay Area.MethodsData come from the SHINE cohort study conducted at the San Francisco Department of Public Health from 2012 to 2014 (n = 263). The relationship between hypothesized psychosocial factors and changes in engagement in condomless receptive anal intercourse over 12-month follow-up was modeled using generalized estimating equations, after adjusting for participant age, race/ethnicity, and education level.ResultsTFY who were ever in a serious relationship since identifying as trans* [adjusted odds ratio (aOR) = 1.89, 95% confidence interval (CI): 1.16 to 3.08], those who reported recent crack/cocaine use (aOR = 2.01, 95% CI: 1.05 to 3.85), and those with a monthly income of more than $500 (aOR = 0.55, 95% CI: 0.35 to 0.85) had significantly higher odds of condomless receptive anal intercourse over the 12-month study period compared to TFY without these exposures. Those who reported high exposure to gender-based discrimination had increased adjusted odds of engagement in condomless receptive anal intercourse compared to those who had low exposure over the study period (aOR = 1.70, 95% CI: 1.10 to 2.63).ConclusionsBoth proximal and structural factors predicted increased engagement in sexual risk behavior among TFY. Results demonstrate the need for a multilevel approach to HIV prevention strategies for this population.

Background: The Office of Disease Prevention and Health Promotion completed research to understand factors that could encourage Americans to follow the Physical Activity Guidelines for Americans, second edition, released in 2018. This study describes survey research assessing demographic characteristics that might be related to knowledge and awareness of the guidelines. Methods: An online survey of 2050 adult physical activity contemplators assessed knowledge of physical activity, awareness of the guidelines, and knowledge of dosage recommendations. Univariate and bivariate analyses were performed, and demographic differences in knowledge and awareness were analyzed using Pearson chi-square tests and Fisher exact tests. Results: Respondents had medium to high knowledge of physical activity, although knowledge varied significantly by socioeconomic factors. Knowledge of dosage recommendations was very low, with 2% and 3% of respondents correctly identifying recommended moderate- and vigorous-intensity doses, respectively. Only 22% were aware of the guidelines; awareness was greater among those with a higher education or income and those without a disability. Conclusions: These findings guided the development of the Office of Disease Prevention and Health Promotion's Move Your Way campaign and reinforced the need to raise awareness of the guidelines and promote behavior change among physical activity contemplators—particularly those from lower socioeconomic groups.
