Mobile populations such as fisherfolk show high HIV incidence and prevalence. We pilot-tested implementation strategies to enhance pre-exposure prophylaxis (PrEP) uptake and adherence in the context of healthcare outreach events in two mainland fisherfolk communities on Lake Victoria, Uganda from September 2021 to February 2022. The implementation strategies included PrEP adherence supporters (selected from PrEP users' social networks), community workshops (to address misconceptions and stigma, and empower PrEP advocacy), and check-in calls (including refill reminders). PrEP medical records data were collected from 6-months pre-intervention to 6-months post-intervention. Qualitative interviews with 20 PrEP users (10 who continued, 10 who discontinued), 9 adherence supporters, and 7 key partners (providers, community leaders) explored acceptability. Percentages of PrEP initiators (of those eligible) were significantly higher during the intervention (96.5%) than 6-months before the intervention (84.5%), p < 0.0001; percentages of PrEP users who persisted (i.e., possessed a refill) 6-months post-initiation (47.9% vs. 6.7%) and had at least 80% PrEP coverage (based on their medication possession ratio) from the initiation date to 6-months later (35.9% vs. 0%) were higher during versus pre-intervention, p < 0.0001. A comparison fisherfolk community with better healthcare access had lower uptake (78.3%; p < 0.0001) and persistence at 6-months (34.0%; p < 0.001), but higher coverage during the intervention period (70.4%; p < 0.0001). Qualitative data suggested the strategies promoted PrEP use through reduced stigma and misconceptions. The intervention bundle cost was $223.95, $172.98, and $94.66 for each additional person for PrEP initiation, persistence, and coverage, respectively. Enhanced community-based PrEP implementation that fosters a supportive community environment can improve PrEP use in mobile populations without easy access to healthcare. (NCT05084716)., (© 2024.

Perinatal depression has been shown to impede adherence to antiretroviral therapy (ART) and the prevention of mother-to-child transmission (PMTCT) care continuum; therefore, treating perinatal depression may result in increased viral suppression and PMTCT adherence. We examined the effects of the M-DEPTH (Maternal Depression Treatment in HIV) depression care model (including antidepressants and individual Problem Solving Therapy) on depression, maternal viral suppression and adherence to PMTCT care processes in an ongoing cluster-randomized controlled trial of 391 HIV-infected pregnant women (200 usual care; 191 intervention) with at least mild depressive symptoms enrolled across 8 antenatal care clinics in Uganda. At baseline, 68.3% had clinical depression and 41.7% had detectable HIV viral load. Adjusted repeated-measures multivariable regression models found that the intervention group was nearly 80% less likely to be clinically depressed [Adjusted OR (95% CI) 0.22 (0.05, 0.89)] at the 2-month post-pregnancy assessment, compared to the control group. However, the intervention and control groups did not differ meaningfully on maternal viral suppression, ART adherence, and other PMTCT care processes and outcomes. In this sample of women who were mostly virally suppressed and ART adherent at baseline, the depression care model had a strong effect on depression alleviation, but no downstream effects on viral suppression or other PMTCT care processes.Trial Registration NIH Clinical Trial Registry NCT03892915 (clinicaltrials.gov)., (© 2023.

The COVID-19 pandemic threatens the food security of people in low-income countries. This is important for people living with HIV (PLWH) because HIV medication should be taken with food to avoid side-effects. We used survey data (n = 314) and qualitative interviews (n = 95) to longitudinally explore how the pandemic impacted food insecurity among PLWH in Kampala, Uganda. Prior to March 2020, 19.7% of respondents were food insecure. Our regression models estimate that food insecurity rose by 9.1 percentage points in our first round of surveys (June-September 2020; p < 0.05; t = 2.17), increasing to 17.2 percentage points in the second round of surveys (July-November 2021; p < 0.05; t = 2.32). Qualitative interviews reveal that employment loss and deteriorating support systems led to reduced meals and purchasing of cheaper foods. Respondents reported continuing to take their HIV medication even in the presence of food insecurity. Strategies for ensuring that PLWH have enough food should be prioritized so that the millions of PLWH in sub-Saharan Africa can take their medication without experiencing uncomfortable side-effects.Clinical Trials Registration Number NCT03494777., (© 2023.

We assessed an intervention aimed at improving adherence to antiretroviral therapy (ART) among pregnant and postpartum women living with HIV (PPWLH). We randomized 133 pregnant women initiating ART in Uganda to receive text reminders generated by real time-enabled electronic monitors and data-informed counseling through 3 months postpartum (PPM3) or standard care. Intention-to-treat analyses found low adherence levels and no intervention impact. Proportions achieving ≥95% adherence in PPM3 were 16.4% vs. 9.1% (t = -1.14, p = 0.26) in intervention vs. comparison groups, respectively; 30.9% vs. 29.1% achieved ≥80% adherence. Additional analyses found significant adherence declines after delivery, and no effect on disease progression (CD4-cell count, viral load), though treatment interruptions were significantly fewer in intervention participants. Per-protocol analyses encompassing participants who used adherence monitors as designed experienced better outcomes, suggesting potential benefit for some PPWLH. The study was registered on ClinicalTrials.Gov (NCT02396394)., (© 2022. The Author(s).)

The health and economic threats posed by the COVID-19 pandemic can be sources of great distress among people living with HIV, which in turn can impact the management of their HIV disease. We examined change in depression from pre- to post-lockdown restrictions and correlates of elevated depressive symptoms, including antiretroviral therapy (ART) adherence. Participants enrolled in a randomized controlled trial of an ART adherence intervention in Uganda. The month-12 follow-up assessment was fully administered just prior to the start of the pandemic-related lockdown in March 2020; at the conclusion of the lockdown three months later, we administered a mixed-methods phone-based assessment. ART adherence was electronically monitored throughout the study period, including during and after the lockdown. Depression was assessed with the 8-item Patient health questionnaire (PHQ-8), on which scores > 9 signify a positive screen for elevated depressive symptoms. A sample of 280 participants completed both the month-12 and post-lockdown assessments. Rates of elevated depressive symptoms nearly tripled from month 12 (n = 17, 6.1%) to the post-lockdown assessment (n = 50, 17.9%; McNemar test < .001). Elevated depressive symptoms at post-lockdown were associated with being female, indicators of economic struggles at month 12 (unemployment, low income, high food insecurity), and lower ART adherence during the 3-month lockdown period [mean of 71.9% (SD = 27.9) vs. 80.8% (SD = 24.1) among those not depressed; p = .041] in bivariate analysis. In multiple regression analysis, higher food insecurity [adj. OR (95% CI) = 4.64 (2.16-9.96)] and perception that the pandemic negatively impacted ART adherence [adj. OR (95% CI) = 1.96 (1.22-3.16)] remained associated with a greater likelihood of elevated depressive symptoms, when other correlates were controlled for. Qualitative data suggested that economic stressors (lack of food, work, and money) were key contributors to elevated depressive symptoms, and these stressors led to missed ART doses because of lack of food and stress induced forgetfulness. Elevated depressive symptoms significantly increased during the COVID-19 lockdown and was associated with food insecurity and reduced ART adherence. Mechanisms for identifying and treating depression and food insecurity are needed to help PLHIV cope with and mitigate the harmful effects of unexpected crises that may impede disease management and access to food., (© 2021.

We tested an intervention that aimed to increase retention in antiretroviral therapy (ART) among HIV-positive pregnant and postpartum women, a population shown to be vulnerable to poor ART outcomes. 133 pregnant women initiating ART at 2 hospitals in Uganda used real time-enabled wireless pill monitors (WPM) for 1 month, and were then randomized to receive text message reminders (triggered by late dose-taking) and data-informed counseling through 3 months postpartum or standard care. We assessed "full retention" (proportion attending all monthly clinic visits and delivering at a study facility; "visit retention" (proportion of clinic visits attended); and "postpartum retention" (proportion retained at 3 months postpartum). Intention-to-treat and per protocol analyses found that retention was relatively low and similar between groups, with no significant differences. Retention declined significantly post-delivery. The intervention was unsuccessful in this population, which experiences suboptimal ART retention and is in urgent need of effective interventions.

Studies have documented how levels and change in depression correspond to ART non-adherence. However, few studies have examined how levels of and change in adherence may relate to levels of and change in depression, although one might expect mental health to be related to physical health and how successful one is in managing disease. To assess the bidirectional nature of the association between these two constructs, we examined data from a prospective trial of an ART adherence intervention in Uganda that followed 143 participants over 20 months. Adherence was measured using electronic monitoring caps; non-adherence was defined as missing > 10% of prescribed doses; self-reported depression was measured using the Patient Health Questionnaire (PHQ-9), and PHQ-9 > 4 defined the presence of at least minor depression. Adjusted linear and logistic regression models were used to examine the longitudinal relationships between depression and non-adherence. At baseline, 40.6% had at least minor depression and 37.1% were non-adherent. Time varying change in the classification of depression (e.g., becoming depressed) predicted change in non-adherence status (e.g., becoming non-adherent), and this association remained when examining continuous measures of the constructs. Similarly, time varying measures of increases in non-adherence predicted increases in depression, regardless of whether continuous or binary classification measures were used. A temporal trend of increased non-adherence over time was observed, and this was accelerated by an increase in depression. Furthermore, those who had at least minor depression at baseline were more likely to be non-adherent at follow-up. These findings support the potential benefits of depression care and adherence support for improving adherence and mental health, respectively, and call for further research to examine such benefits.The trial has been registered with ClinicalTrials.gov (NCT02503072).

Increasing HIV diagnosis is important for combatting HIV. We invited individuals aged ≥ 13 years seeking voluntary HIV testing at Mildmay Clinic in Uganda to undertake a computer or audio-computer-assisted self-interview to facilitate post-test counseling. We evaluated first-visit data from 12,233 consenting individuals between January 2011 and October 2013. HIV prevalence was 39.0%. Of those with HIV, 37.2% already knew they were infected. Undiagnosed infection was associated with not being single, screening positive for depression (aOR 1.16, 95% CI 1.04-1.28), and screening for harmful drinking behavior (aOR 1.23, 95% CI 1.10-1.39). The odds of retesting subsequent to HIV diagnosis were lower for males (aOR 0.80, 95% CI 0.70-0.92) and those screening positive for harmful drinking behavior (aOR 0.77, 95% CI 0.66-0.88). Retesting was also associated with higher education and perceived social status below 'better off'. Our findings reiterate the value of population-based HIV surveys to provide estimates of testing coverage.

With depression known to impede HIV care adherence and retention, we examined whether depression alleviation improves these disease management behaviors. A sample of 1028 depressed HIV clients in Uganda enrolled in a cluster randomized controlled trial of two depression care models, and were surveyed over 12 months. Serial regression analyses examined whether depression alleviation was associated with self-reported antiretroviral therapy (ART) adherence and clinic attendance at month 12, and whether these relationships were mediated by self-efficacy and motivation. Among those with major depression, depression alleviation was associated with better ART adherence and clinic attendance at month 12; these relationships were fully mediated by self-efficacy at month 12, while adherence motivation partially mediated the relationship between depression alleviation and ART adherence. When both mediators were entered simultaneously, only self-efficacy was a significant predictor and still fully mediated the relationship between depression alleviation and adherence. These findings suggest that depression alleviation benefits both ART adherence and clinic attendance, in large part through improved confidence and motivation to engage in these disease management behaviors.

We compared two community-based HIV testing models among fisherfolk in Lake Victoria, Uganda. From May to July 2015, 1364 fisherfolk residents of one island were offered (and 822 received) home-based testing, and 344 fisherfolk on another island were offered testing during eight community mobilization events (outreach event-based testing). Of 207 home-based testing clients identified as HIV-positive (15% of residents), 82 were newly diagnosed, of whom 31 (38%) linked to care within 3 months. Of 41 who screened positive during event-based testing (12% of those tested), 33 were newly diagnosed, of whom 24 (75%) linked to care within 3 months. Testing costs per capita were similar for home-based ($45.09) and event-based testing ($46.99). Compared to event-based testing, home-based testing uncovered a higher number of new HIV cases but was associated with lower linkage to care. Novel community-based test-and-treat programs are needed to ensure timely linkage to care for newly diagnosed fisherfolk., Competing Interests: COMPLIANCE WITH ETHICAL STANDARDS: There are no conflicts of interest to disclose. All human subjects procedures performed in this study were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. Informed consent was obtained from all individual participants included in the study.

Among Ugandan fisherfolk, HIV prevalence (with estimates ranging from 15 to 40 %) is higher than in the general population (about 7 %), potentially due to high-risk behaviors and low access to HIV testing and healthcare. We conducted semi-structured interviews on barriers to linkage to care with 10 key stakeholders and 25 fisherfolk within 1-2 months of their testing HIV-positive at clinic outreach events in Ugandan Lake Victoria communities. Interviews were recorded, transcribed, translated, and coded using grounded theory methods. Participants cited low healthcare access and quality of care, mobility, competing needs for work during clinic hours, stigma, and low social support as barriers. Over 10 % of clients screened positive for HIV at outreach events, and only half accessed care. Linkage to care issues may begin with the failure to attract high-risk fisherfolk to testing. New models of HIV testing and treatment delivery are needed to reach fisherfolk.
