Incidence of Health Facility Switching and Associations With HIV Viral Rebound Among Persons on Antiretroviral Therapy in Uganda: A Population-based Study.

BACKGROUND: A substantial proportion of persons on antiretroviral therapy (ART) considered lost to follow-up have actually transferred their human immunodeficiency virus (HIV) care to other facilities. However, the relationship between facility switching and virologic outcomes, including viral rebound, is poorly understood. METHODS: We used data from 40 communities (2015-2020) in the Rakai Community Cohort Study to estimate incidence of facility switching and viral rebound. Persons aged 15-49 years with serologically confirmed HIV who self-reported ART use and contributed ≥1 follow-up visit were included. Facility switching and virologic outcomes were assessed between 2 consecutive study visits (ie, index and follow-up visits, interval of approximately 18 months). Those who reported different HIV treatment facilities between index and follow-up study visits were classified as having switched facilities. Virologic outcomes included viral rebound among individuals initially suppressed (<200 copies/mL). Multivariable Poisson regression was used to estimate associations between facility switching and viral rebound. RESULTS: Overall, 2257 persons who self-reported ART use (median age, 35 years; 65% female, 92% initially suppressed) contributed 3335 visit-pairs and 5959 person-years to the analysis. Facility switching was common (4.8 per 100 person-years; 95% confidence interval [CI], 4.2-5.5) and most pronounced in persons aged <30 years and fishing community residents. Among persons suppressed at their index visit (n = 2076), incidence of viral rebound was more than twice as high in persons who switched facilities (adjusted incidence rate ratio = 2.27; 95% CI, 1.16-4.45). CONCLUSIONS: Facility switching was common and associated with viral rebound among persons initially suppressed. Investments in more agile, person-centered models for mobile clients are needed to address system inefficiencies and bottlenecks that can disrupt HIV care continuity.

Effectiveness of intensive adherence counselling in achieving an undetectable viral load among people on antiretroviral therapy with low-level viraemia in Uganda.

INTRODUCTION: Uganda was using a threshold of 1000 copies/mL to determine viral non-suppression for antiretroviral therapy monitoring among people living with HIV, prior to this study. It was not clear whether people living with HIV with low-level viraemia (LLV, ≥50 to <1000 copies/mL) would benefit from intensive adherence counselling (IAC). The purpose of this study was to determine the effectiveness of IAC among people living with HIV, receiving antiretroviral therapy, and with LLV in Uganda, to guide key policy decisions in HIV care, including the review of the viral load (VL) testing algorithm. METHODS: This cluster-randomized clinical trial comprised adults from eight HIV clinics who were living with HIV, receiving ART, and had recent VL results indicating LLV (tested from July 2022 to October 2022). Participants in the intervention arm clinics received three once-monthly sessions of IAC, and those in the comparison non-intervention arm clinics received the standard of care. At the end of the study, all participants were re-tested for VL to determine the proportions of those who then had an undetectable VL (<50 copies/mL). We assessed the statistical association between cross-tabulated variables using Fisher's exact test and then modified Poisson regression. RESULTS: A total of 136 participants were enrolled into the study at eight HIV clinics. All 68 participants in the intervention arm completed all IAC sessions. Only one participant in the non-intervention arm was lost to follow-up. The average follow-up time was 3.7 months (standard deviation [SD] 0.2) and 3.5 months (SD 0.1) in the intervention and non-intervention arms, respectively. In total, 59 (43.7%) of 135 people living with HIV achieved an undetectable VL during the study follow-up period. The effect of IAC on attaining an undetectable VL among people with LLV was nearly twice as high in the intervention arm (57.4%) than in the non-intervention arm (29.9%): adjusted risk ratio 1.9 (95% confidence interval 1.0-3.5), p = 0.037. CONCLUSION: IAC doubled the likelihood of an undetectable VL among people living with HIV with LLV. Therefore, IAC has been instituted as an intervention to manage people living with HIV with LLV in Uganda, and this should also be adopted in other Sub-Saharan African countries with similar settings.

Willingness to receive COVID-19 vaccines, associated factors and reasons for not taking a vaccine: a cross sectional study among persons aged 13-80 years in Wakiso, Central Uganda.

BACKGROUND: Vaccination has been recommended as one of the approaches for the control of COVID-19 pandemic. However, adequate vaccine coverage is critical to the effectiveness of the vaccine at population level. Data on acceptability of the vaccine in Ugandan urban areas are limited. This study examined the prevalence, factors associated with willingness to accept COVID-19 vaccine including reasons for not taking COVID-19 vaccine in a predominantly urban population of Wakiso, central Uganda. METHODS: Data were obtained from a cross-sectional study conducted between March 1st, 2021 and September 30th, 2021 in the urban population-based cohort of the Africa Medical and behavioral Sciences Organization (AMBSO). A Multivariable modified Poisson regression analysis was used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals of willingness to accept the COVID-19 vaccine. RESULTS: A total of 1,903 participants were enrolled in this study; 61% of whom were females. About 63% of participants indicated their willingness to accept the COVID-19 vaccine. Persons aged 13-19 years (aPR = 0.79; [95% CI: 0.74, 0.84]) or 20-29years (aPR = 0.93; [95% CI: 0.88, 0.98]) were less likely to accept the vaccine compared to persons aged 40-49 years. Persons with post-primary level of education (aPR = 1.05; [95% CI: 1.02, 1.09]) were more likely to accept the vaccine compared to persons with primary level of education. Additionally, students or individuals working in government (aPR = 1.13; [95% CI: 1.04, 1.23]) were more likely to accept the vaccine compared to individuals doing construction and Mechanic work as their main occupation. Reported reasons for not taking a COVID-19 vaccine included; concerns about side effects of the vaccine 154(57.0%), 64(23.7%) did not think the vaccines were effective, while 32(11.9%) did not like the vaccines. CONCLUSION: A substantial proportion of individuals were not willing to accept the COVID-19 vaccine. Health education campaigns on vaccination within urban communities could help reduce COVID-19 vaccine misconceptions in the urban populations more especially the young and persons with low levels of formal education.

Capacity to Consent to Research Among Adolescent-Parent Dyads in Rakai, Uganda.

OBJECTIVES: To assess the cognitive capacity of early, middle, and late adolescents and their parents or guardians to provide informed consent to a population-based cohort study. STUDY DESIGN: Adolescent-parent/guardian dyads including 40 early (n = 80; 10-14 years), 20 middle (15-17 years), and 20 late (18-19 years) adolescents were recruited from the Rakai Community Cohort Study, an open demographic cohort in Uganda. Participants were administered the MacArthur Competence Assessment Tool for Clinical Research, a structured open-ended assessment; interviews were recorded and transcribed. Twenty transcripts were scored independently by two coders; the intraclass correlation coefficient was 0.89. The remaining interviews were scored individually. We compared mean scores for early and middle/late adolescents using a one-sided t test and score differences between parent/guardian and adolescent dyads using two-sided paired t tests. RESULTS: Early adolescents (mean score, 28.8; 95% CI, 27.1-30.5) scored significantly lower (P < .01) than middle/late adolescents (32.4; 31.6-33.1). In paired dyad comparisons, we observed no statistically significant difference in scores between parents/guardians and middle/late adolescents (difference, -0.2; 95% CI, -1.0-0.6). We found a statistically significant difference in scores between parents/guardians and early adolescents (difference, 3.0; 95% CI, 1.2-4.8). CONCLUSIONS: The capacity of adolescents-of different ages and in diverse settings-to comprehend risks, benefits, and other elements of informed consent is a critical but understudied area in research ethics. Our findings support the practice of having middle and late adolescents provide independent informed consent for sexual and reproductive health studies. Early adolescents may benefit from supported decision-making approaches.

In the era of universal test and treat in Uganda, recent intimate partner violence is not associated with subsequent ART use or viral suppression.

Intimate partner violence (IPV) has been associated with delays throughout the HIV care continuum. This study explored prospective associations between experiences of past-year IPV and two HIV care outcomes in the context of current universal test and treat guidelines using two consecutive rounds of an ongoing HIV surveillance study conducted in the Rakai region of Uganda. Longitudinal logistic regression models examined associations between IPV, use of antiretroviral therapy (ART) and viral load suppression (VS), adjusting for outcome variables at baseline. To address differences in ART retention by IPV, propensity scores were used to create inverse-probability-of-treatment-and-censoring-weighted (IPTCW) models. At baseline, of 1923 women with HIV (WWH), 34.6%, 26.5%, 13.5% reported past-year verbal, physical and sexual IPV; a lower proportion of persons who experienced physical IPV (79.4%) were VS than those who did not (84.3%; p = 0.01). The proportion VS at baseline also significantly differed by exposure to verbal IPV (p = 0.03). However, in adjusted longitudinal models, IPV was not associated with lower odds of ART use or VS at follow-up. Among WWH in the Rakai region, IPV does not appear to be a barrier to subsequent ART use or VS. However, given the prevalence of IPV in this population, interventions are needed.

Gendered access to digital capital and mobile phone ownership among young people in Rakai, Uganda.

This article examines how gendered access to digital capital-in the form of the social and economic resources needed to own and use a mobile phone-is connected to key adult milestones, such as securing employment and engaging in romantic relationships. Descriptive statistical analysis of 11,030 young people aged 15-24 in Rakai, Uganda indicated that men were more likely to own mobile phones than women. Analysis of qualitative interviews with young people (N = 31) and ethnographic participant observations among young people (N = 24) add nuance and depth to the observed gender difference. We go beyond a 'categorical' approach to gender (i.e. comparing rates between men and women) to examine how access to digital capital is gendered both for men and for women. Mobile phone ownership both reproduces and destabilises gendered social organisation in ways that have implications for economic opportunities, social connections, HIV risk and overall health and well-being. Young men had greater access to the benefits of mobile phone ownership, whereas young women's access to those benefits was impeded by covert and overt gendered mechanisms of control that limited access to digital capital. Findings suggest that mhealth initiatives, increasingly deployed to reach under-resourced populations, must take into account gendered access to digital capital.

Dissolution of transactional sex relationships during COVID-19: a qualitative study of Ugandan men's experiences during COVID-19 lockdowns.

The COVID-19 pandemic and subsequent mitigation measures led to social disruption and negative economic shocks for a large proportion of Uganda's population. The social and economic consequences of COVID-19 on Ugandan men's sexual behaviours, including transactional sex relationships, are unclear. We conducted in-depth interviews between November 2021-February 2022 with 26 men in a high HIV prevalence region of Uganda. Data were analysed thematically to understand how sexual relationships, including transactional sex, were impacted by COVID-19. We found that COVID-19 mitigation measures had far-reaching social and economic impacts on most respondents, particularly those employed in the informal economy. Men described experiencing job loss, food insecurity and restricted mobility, which limited opportunities to provide for and meet with transactional sex partners. Inability to provide financial resources meant that men could not form new transactional sex relationships and men who could no longer provide for their existing transactional sex partners consistently reported relationship dissolution. Men who reported stable employment during the pandemic described few changes in transactional sex relationships. Similarly, men in non-transactional relationships did not report relationship dissolution despite decreased financial provision. Further research should assess the potential short- and long-term impacts of COVID-19 mitigation measures on transactional sex relationships.

Women's support for voluntary medical male circumcision in fishing communities on the shores of Lake Victoria, Uganda.

BACKGROUND: Women's support can improve uptake of voluntary medical male circumcision (VMMC). We assessed the level of women's support for VMMC and associated factors in fishing settlements on the shores of Lake Victoria in Uganda, to inform interventions aimed at increasing the uptake of safe male circumcision services in such high-risk populations. METHODS: We conducted a cross-sectional study, employing mixed methods of data collection, at Kasenyi and Kigungu landing sites in April 2018. We included women aged 18-49 years, who had stayed at the landing sites for ≥3 months. We obtained qualitative data using focus group discussions (FGDs), and interviewer-administered semi-structured questionnaires for quantitative data. The tool captured demographic characteristics, community factors including cultural norms and beliefs, women's experiences, and health facility-related factors. The dependent variable was derived from the response to the question: "Would you encourage your partner/husband to go for VMMC?", and used as a proxy for support of VMMC. We used modified Poisson regression to identify factors associated with women's support for VMMC. Qualitative data were analysed using thematic content analysis. RESULTS: We enrolled 313 women with a mean age of 28 (SD±6.8) years. Of the 313 women, 230 (73.5%) supported VMMC. Belief that VMMC increases penile hygiene (Adjusted prevalence ratio [aPR]=1.9; CI: 1.8-3.2), performing VMMC for religious reasons (aPR=1.9; CI: 1.8-2.9), preference for a circumcised man (aPR=1.3; CI: 1.2-1.5), belief that vaginal fluids facilitate wound healing (aPR=1.9; CI: 1.3-2.7), and knowledge about when a man can resume sex (4 weeks) after circumcision (aPR=2.1; CI: 1.8-3.3) were associated with women's support for VMMC. FGDs revealed that women were not adequately involved in VMMC activities for decision making. CONCLUSION: The support for VMMC was high among women in the fishing communities. However, women perceived they were not involved in decision-making for VMMC and had several misconceptions, including a belief that vaginal fluids facilitate wound healing. The Ministry of Health and VMMC implementing partners should devise strategies to increase sensitization and involvement of women in VMMC decision-making without slowing service uptake.

Prevalence and Predictors of Persistent Human Immunodeficiency Virus Viremia and Viral Rebound After Universal Test and Treat: A Population-Based Study.

BACKGROUND: There are limited data on individual human immunodeficiency virus (HIV) viral load (VL) trajectories at the population-level after the introduction of universal test and treat (UTT) in sub-Saharan Africa. METHODS: Human immunodeficiency virus VLs were assessed among HIV-positive participants through 3 population-based surveys in 4 Ugandan fishing communities surveyed between November 2011 and August 2017. The unit of analysis was a visit-pair (2 consecutive person-visits), which were categorized as exhibiting durable VL suppression, new/renewed VL suppression, viral rebound, or persistent viremia. Adjusted relative risks (adjRRs) and 95% confidence intervals (CIs) of persistent viremia were estimated using multivariate Poisson regression. RESULTS: There were 1346 HIV-positive participants (n = 1883 visit-pairs). The population-level prevalence of durable VL suppression increased from 29.7% to 67.9% during UTT rollout, viral rebound declined from 4.4% to 2.7%, and persistent viremia declined from 20.8% to 13.3%. Younger age (15-29 vs 40-49 years; adjRR = 1.80; 95% CI = 1.19-2.71), male sex (adjRR = 2.09, 95% CI = 1.47-2.95), never being married (vs currently married; adjRR = 1.88, 95% CI = 1.34-2.62), and recent migration to the community (vs long-term resident; adjRR = 1.91, 95% CI = 1.34-2.73) were factors associated with persistent viremia. CONCLUSIONS: Despite increases in durable VL suppression during roll out of UTT in hyperendemic communities, a substantial fraction of the population, whose risk profile tended to be younger, male, and mobile, remained persistently viremic.

Effectiveness of Voluntary Medical Male Circumcision for Human Immunodeficiency Virus Prevention in Rakai, Uganda.

BACKGROUND: The efficacy of voluntary male medical circumcision (VMMC) for human immunodeficiency virus (HIV) prevention in men was demonstrated in 3 randomized trials. This led to the adoption of VMMC as an integral component of the United States President's Emergency Plan for AIDS Relief (PEPFAR) combination HIV prevention program in sub-Saharan Africa. However, evidence on the individual-level effectiveness of VMMC programs in real-world, programmatic settings is limited. METHODS: A cohort of initially uncircumcised, non-Muslim, HIV-uninfected men in the Rakai Community Cohort Study in Uganda was followed between 2009 and 2016 during VMMC scale-up. Self-reported VMMC status was collected and HIV tests performed at surveys conducted every 18 months. Multivariable Poisson regression was used to estimate the incidence rate ratio (IRR) of HIV acquisition in newly circumcised vs uncircumcised men. RESULTS: A total of 3916 non-Muslim men were followed for 17 088 person-years (PY). There were 1338 newly reported VMMCs (9.8/100 PY). Over the study period, the median age of men adopting VMMC declined from 28 years (interquartile range [IQR], 21-35 years) to 22 years (IQR, 18-29 years) (P for trend < .001). HIV incidence was 0.40/100 PY (20/4992.8 PY) among newly circumcised men and 0.98/100 PY (118/12 095.1 PY) among uncircumcised men with an adjusted IRR of 0.47 (95% confidence interval, .28-.78). The effectiveness of VMMC was sustained with increasing time from surgery and was similar across age groups and calendar time. CONCLUSIONS: VMMC programs are highly effective in preventing HIV acquisition in men. The observed effectiveness is consistent with efficacy in clinical trials and supports current recommendations that VMMC is a key component of programs to reduce HIV incidence.

Novel community health worker strategy for HIV service engagement in a hyperendemic community in Rakai, Uganda: A pragmatic, cluster-randomized trial.

BACKGROUND: Effective implementation strategies are needed to increase engagement in HIV services in hyperendemic settings. We conducted a pragmatic cluster-randomized trial in a high-risk, highly mobile fishing community (HIV prevalence: approximately 38%) in Rakai, Uganda, to assess the impact of a community health worker-delivered, theory-based (situated Information, Motivation, and Behavior Skills), motivational interviewing-informed, and mobile phone application-supported counseling strategy called "Health Scouts" to promote engagement in HIV treatment and prevention services. METHODS AND FINDINGS: The study community was divided into 40 contiguous, randomly allocated clusters (20 intervention clusters, n = 1,054 participants at baseline; 20 control clusters, n = 1,094 participants at baseline). From September 2015 to December 2018, the Health Scouts were deployed in intervention clusters. Community-wide, cross-sectional surveys of consenting 15 to 49-year-old residents were conducted at approximately 15 months (mid-study) and at approximately 39 months (end-study) assessing the primary programmatic outcomes of self-reported linkage to HIV care, antiretroviral therapy (ART) use, and male circumcision, and the primary biologic outcome of HIV viral suppression (<400 copies/mL). Secondary outcomes included HIV testing coverage, HIV incidence, and consistent condom use. The primary intent-to-treat analysis used log-linear binomial regression with generalized estimating equation to estimate prevalence risk ratios (PRR) in the intervention versus control arm. A total of 2,533 (45% female, mean age: 31 years) and 1,903 (46% female; mean age 32 years) residents completed the mid-study and end-study surveys, respectively. At mid-study, there were no differences in outcomes between arms. At end-study, self-reported receipt of the Health Scouts intervention was 38% in the intervention arm and 23% in the control arm, suggesting moderate intervention uptake in the intervention arm and substantial contamination in the control arm. At end-study, intention-to-treat analysis found higher HIV care coverage (PRR: 1.06, 95% CI: 1.01 to 1.10, p = 0.011) and ART coverage (PRR: 1.05, 95% CI: 1.01 to 1.10, p = 0.028) among HIV-positive participants in the intervention compared with the control arm. Male circumcision coverage among all men (PRR: 1.05, 95% CI: 0.96 to 1.14, p = 0.31) and HIV viral suppression among HIV-positive participants (PRR: 1.04, 95% CI: 0.98 to 1.12, p = 0.20) were higher in the intervention arm, but differences were not statistically significant. No differences were seen in secondary outcomes. Study limitations include reliance on self-report for programmatic outcomes and substantial contamination which may have diluted estimates of effect. CONCLUSIONS: A novel community health worker intervention improved HIV care and ART coverage in an HIV hyperendemic setting but did not clearly improve male circumcision coverage or HIV viral suppression. This community-based, implementation strategy may be a useful component in some settings for HIV epidemic control. TRIAL REGISTRATION: ClinicalTrials.gov NCT02556957.

Transactional Sex, Alcohol Use and Intimate Partner Violence Against Women in the Rakai Region of Uganda.

Transactional sex (TS) is prevalent in sub-Saharan Africa. Women's engagement in TS is linked with HIV infection; little is known about the relationship between TS, intimate partner violence (IPV) and alcohol use-established HIV risk behaviors. Using modified Poisson regression, we assessed associations between TS and physical, verbal and sexual IPV among 8248 women (15-49 years) who participated in the Rakai Community Cohort Study across forty communities in Uganda. An interaction term assessed moderation between alcohol use and TS and no significant interaction effects were found. In adjusted analysis, alcohol use and TS were significantly associated with all forms of IPV. In stratified analysis, TS was only associated with IPV in agrarian communities; alcohol use was not associated with physical IPV in trade communities or sexual IPV in trade and fishing communities. Identifying differences in IPV risk factors by community type is critical for the development of tailored interventions.

RESUMEN: El sexo transaccional (ST) es frecuente en África subsahariana. La participación de las mujeres en el ST está relacionada con la infección por VIH; Se sabe poco sobre la relación entre el ST, la violencia de pareja íntima (VPI) y el consumo de alcohol: conductas de riesgo establecidas para el VIH. Utilizando la regresión de Poisson modificada, evaluamos las asociaciones entre el ST y la VPI física, verbal y sexual entre 8,248 mujeres (15-49 años) que participaron en el Estudio de cohorte de la comunidad Rakai en cuarenta comunidades de Uganda. Un término de interacción evaluó la moderación entre el consumo de alcohol y el ST y no se encontraron efectos de interacción significativos. En el análisis ajustado, el consumo de alcohol y el ST se asociaron significativamente con todas las formas de VPI. En el análisis estratificado, el ST solo se asoció con la VPI en las comunidades agrarias; El consumo de alcohol no se asoció con la VPI física en las comunidades comerciales ni con la VPI sexual en las comunidades comerciales y pesqueras. Identificar las diferencias en los factores de riesgo de la violencia de género por tipo de comunidad es fundamental para el desarrollo de intervenciones personalizadas.

Qualitative Assessment of Barriers and Facilitators of PrEP Use Before and After Rollout of a PrEP Program for Priority Populations in South-central Uganda.

Uganda piloted HIV pre-exposure prophylaxis (PrEP) for priority populations (sex workers, fishermen, truck drivers, discordant couples) in 2017. To assess facilitators and barriers to PrEP uptake and adherence, we explored perceptions of PrEP before and experiences after rollout among community members and providers in south-central Uganda. We conducted 75 in-depth interviews and 12 focus group discussions. We analyzed transcripts using a team-based thematic framework approach. Partners, family, peers, and experienced PrEP users provided adherence support. Occupational factors hindered adherence for sex workers and fishermen, particularly related to mobility. Pre-rollout concerns about unskilled/untrained volunteers distributing PrEP and price-gouging were mitigated. After rollout, awareness of high community HIV risk and trust in PrEP effectiveness facilitated uptake. PrEP stigma and unexpected migration persisted as barriers. Community-initiated, tailored communication with successful PrEP users may optimize future engagement by addressing fears and rumors, while flexible delivery and refill models may facilitate PrEP continuation and adherence.

RESUMEN: En 2017, Uganda introdujo profilaxis pre-exposición (PrEP), dirigida a las populaciones con alto riesgo de contraer al VIH (trabajadoras sexuales, pescadores, camioneros, parejas sero-discordantes). Para investigar facilitadores y barreras para la adopción y la adherencia a la PrEP, exploramos percepciones de PrEP antes y después de su introducción en Uganda. Realizamos 75 entrevistas y 12 grupos focales con miembros de la comunidad y trabajadores de salud. Analizamos las transcripciones temáticamente usando un marco de referencia. Parejas, familias, compañeros, y clientes usando PrEP apoyaron a los demás mantener adherencia. Movilidad fue una barrera para la adherencia a la PrEP para trabajadoras sexuales y pescadores. Preocupaciones sobre el entrenamiento de los distribuidores de PrEP y la especulación de precios no fueron realizadas. Percepciones del riesgo del VIH y confianza en la eficacia de PrEP facilitaron su adopción. Estigma y migración inesperada persistieron como barreras para la adopción de PrEP. Comunicaciones manejadas por clientes usando PrEP pueden motivar interés en PrEP y abordar rumores. Sistemas flexibles del entrego y la recarga de medicinas pueden permitir continuación de, y adherencia a, la PrEP.

The Promise and Peril of Mobile Phones for Youth in Rural Uganda: Multimethod Study of Implications for Health and HIV.

BACKGROUND: In East Africa, where landlines are used by 1% of the population and access to the internet is limited, owning a cell phone is rapidly becoming essential for acquiring information and resources. Our analysis illuminates the perils and potential promise of mobile phones with implications for future interventions to promote the health of adolescents and young adults (AYAs) and to prevent HIV infection. OBJECTIVE: The aim of this study is to describe the current state of AYAs' phone use in the region and trace out the implications for mobile health interventions. METHODS: We identified 2 trading centers that were representative of southern Uganda in terms of key demographics, proportion of cell phone ownership, and community HIV prevalence. We stratified the sample of potential informants by age group (15-19 years and 20-24 years), gender, and phone ownership and randomly sampled 31 key informant interview participants within these categories. In addition, we conducted 24 ethnographic participant observations among AYAs in the communities of study. RESULTS: AYA frequently reported barriers to using their phones, such as difficulty accessing electricity. Nearly all AYAs used mobile phones to participate in the local economy and communicate with sexual partners. Phone use was frequently a point of contention between sexual partners, with many AYAs reporting that their sexual partners associated phone use with infidelity. Few AYAs reported using their phones for health-related purposes, with most getting health information in person from health workers. However, most AYAs reported an instance when they used their phone in an emergency, with childbirth-related emergencies being the most common. Finally, most AYAs reported that they would like to use their phones for health purposes and specifically stated that they would like to use their mobile phones to access current HIV prevention information. CONCLUSIONS: This study demonstrates how mobile phones are related to income-generating practices in the region and communication with sexual partners but not access to health and HIV information. Our analysis offers some explanation for our previous study, which suggested an association between mobile phone ownership, having multiple sexual partners, and HIV risk. Mobile phones have untapped potential to serve as tools for health promotion and HIV prevention.

Not Enough Money and Too Many Thoughts: Exploring Perceptions of Mental Health in Two Ugandan Districts Through the Mental Health Literacy Framework.

Mental health disorders account for a heavy disease burden in Uganda. In order to provide culturally appropriate mental health prevention and treatment approaches, it is necessary to understand how mental health is conceptualized in the population. Three focus group discussions (FGDs) and 31 in-depth interviews (IDIs) were conducted with men and women aged 14 to 62 years residing in rural, urban, and semi-urban low-income communities in central and western Uganda to explore perceptions and knowledge of mental health. Interpretive thematic analysis was undertaken; results were organized through the lens of the mental health literacy framework. Environmental and societal stressors were identified as primary underlying causes of poor mental health. While participants recognized symptoms of poor mental health, gaps in mental health literacy also emerged. Mental health resources are needed in this setting and additional qualitative work assessing knowledge and attitudes toward mental health care seeking behavior can inform the development of acceptable integrated services.

HIV Prevention Efforts and Incidence of HIV in Uganda.

BACKGROUND: To assess the effect of a combination strategy for prevention of human immunodeficiency virus (HIV) on the incidence of HIV infection, we analyzed the association between the incidence of HIV and the scale-up of antiretroviral therapy (ART) and medical male circumcision in Rakai, Uganda. Changes in population-level viral-load suppression and sexual behaviors were also examined. METHODS: Between 1999 and 2016, data were collected from 30 communities with the use of 12 surveys in the Rakai Community Cohort Study, an open, population-based cohort of persons 15 to 49 years of age. We assessed trends in the incidence of HIV on the basis of observed seroconversion data, participant-reported use of ART, participant-reported male circumcision, viral-load suppression, and sexual behaviors. RESULTS: In total, 33,937 study participants contributed 103,011 person-visits. A total of 17,870 persons who were initially HIV-negative were followed for 94,427 person-years; among these persons, 931 seroconversions were observed. ART was introduced in 2004, and by 2016, ART coverage was 69% (72% among women vs. 61% among men, P<0.001). HIV viral-load suppression among all HIV-positive persons increased from 42% in 2009 to 75% by 2016 (P<0.001). Male circumcision coverage increased from 15% in 1999 to 59% by 2016 (P<0.001). The percentage of adolescents 15 to 19 years of age who reported never having initiated sex (i.e., delayed sexual debut) increased from 30% in 1999 to 55% in 2016 (P<0.001). By 2016, the mean incidence of HIV infection had declined by 42% relative to the period before 2006 (i.e., before the scale-up of the combination strategy for HIV prevention) - from 1.17 cases per 100 person-years to 0.66 cases per 100 person-years (adjusted incidence rate ratio, 0.58; 95% confidence interval [CI], 0.45 to 0.76); declines were greater among men (adjusted incidence rate ratio, 0.46; 95% CI, 0.29 to 0.73) than among women (adjusted incidence rate ratio, 0.68; 95% CI, 0.50 to 0.94). CONCLUSIONS: In this longitudinal study, the incidence of HIV infection declined significantly with the scale-up of a combination strategy for HIV prevention, which provides empirical evidence that interventions for HIV prevention can have a population-level effect. However, additional efforts are needed to overcome disparities according to sex and to achieve greater reductions in the incidence of HIV infection.

Elevated liver stiffness without histological evidence of liver fibrosis in rural Ugandans.

Liver fibrosis may be assessed noninvasively with transient electrography (TE). Data on the performance of TE for detecting liver fibrosis in sub-Saharan Africa are limited. We evaluated the diagnostic accuracy of TE by performing liver biopsies on persons with liver fibrosis indicated by TE. We enrolled HIV-infected and HIV-uninfected participants with TE scores consistent with at least minimal disease (liver stiffness measurement [LSM]≥7.1 kPa). Biopsies were performed and staged using the Ishak scoring system. A concordant result was defined using accepted thresholds for significant fibrosis by TE (LSM ≥ 9.3 kPa) and liver biopsy (Ishak score ≥ 2). We used modified Poisson regression methods to quantify the univariate and adjusted prevalence risk ratios (PRR) of the association between covariates and the concordance status of TE and liver biopsy in defining the presence of liver fibrosis. Of 131 participants with valid liver biopsy and TE data, only 5 participants (3.8%) had Ishak score ≥ 2 of whom 4 had LSM ≥ 9.3 kPa (sensitivity = 80%); of the 126 (96.2%) with Ishak score < 2, 76 had LSM < 9.3 kPa (specificity = 61%). In multivariable analysis, discordance was associated with female gender (adjPRR = 1.80, 95%CI 1.1-2.9; P = .019), herbal medicine use (adjPRR 1.64, 95% CI = 1.0-2.5; P = .022), exposure to lake or river water (adjPRR 2.05, 95% CI = 1.1-3.7; P = .016), and current smoking (adjPRR 1.72, 95%CI 1.0-2.9; P = .045). These data suggest that TE among rural Ugandans has low specificity for detection of histologically confirmed liver fibrosis. Caution should be exercised when using this tool to confirm significant liver fibrosis.

Cell Phones, Sexual Behaviors and HIV Prevalence in Rakai, Uganda: A Cross Sectional Analysis of Longitudinal Data.

Cell phones have increased communication and connection across the globe and particularly in sub-Saharan Africa-with potential consequences for the HIV epidemic. We examined the association among ownership of cell phones, sexual behaviors (number of sexual partners, alcohol use before sex, inconsistent condom use), and HIV prevalence. Data were from four rounds (2010-2016) of the Rakai Community Cohort Study (N = 58,275). Sexual behaviors and HIV prevalence were compared between people who owned a cell phone to people who did not own a cell phone. We stratified analysis by younger (15-24 years) and older (25+ years) age groups and by gender. Using logistic regression and after adjusting for sociodemographic characteristics, we found cell phone ownership was independently associated with increased odds of having two or more sexual partners in the past 12 months across age and gender groups (young men AOR 1.67, 95% CI 1.47-1.90; young women AOR 1.28 95% CI 1.08-1.53; older men AOR 1.54 95% CI 1.41-1.69; older women AOR 1.44 95% CI 1.26-1.65). Interestingly, young men who owned cell phones had decreased odds of using condoms inconsistently (AOR 0.66, 95% CI 0.57-0.75). For young women, cell phone ownership was associated with increased odds of using alcohol before sex (AOR 1.38 95% CI 1.17-1.63) and increased odds of inconsistent condom use (AOR 1.40, 95% 1.17-1.67). After adjusting for sociodemographic characteristics, only young women who owned cell phones had increased odds of being HIV positive (AOR 1.27 95% CI 1.07-1.50). This association was not mediated by sexual behaviors (Adjusted for sociodemographic characteristics and sexual behaviors AOR 1.24, 95% CI 1.05-1.46). While cell phone ownership appears to be associated with increased HIV risk for young women, we also see a potential opportunity for future cell phone-based health interventions.

Antiretroviral treatment sharing among highly mobile Ugandan fisherfolk living with HIV: a qualitative study.

Antiretroviral treatment (ART) diversion from prescribed to non-prescribed users (i.e., sharing or selling) is an understudied dimension of HIV treatment adherence. We sought to explore ART diversion patterns in high-prevalence fishing communities on Lake Victoria, Uganda. We implemented a qualitative study in two fishing communities on Lake Victoria in south-central Uganda to identify facilitators of and pathways to ART diversion. We conducted 25 semi-structured interviews with HIV-positive fishermen (n = 25) and female sex workers (n = 10) covering personal and community experiences with ART selling/sharing, reasons for medication diversion, and potential solutions to reduce diversion. Data were analyzed using an adapted framework analysis approach. Participants reported frequent ART sharing within occupational networks, but no selling. Mobility was the principal driver of ART sharing and was associated with other barriers to treatment access including stigma, fear of negative health provider interactions, and transportation. ART sharing appears to emerge in response to short-term treatment interruptions in this setting. Future studies should explore characteristics and drivers of ART diversion in other high-burden settings and identify how these practices are correlated with key health outcomes like virologic failure and drug resistance.

Population-level adult mortality following the expansion of antiretroviral therapy in Rakai, Uganda.

There are limited data on the impact of antiretroviral therapy (ART) on population-level adult mortality in sub-Saharan Africa. We analysed data for 2000-14 from the Rakai Community Cohort Study (RCCS) in Uganda, where free ART was scaled up after 2004. Using non-parametric and parametric (Weibull) survival analysis, we estimated trends in average person-years lived between exact ages 15 and 50, per capita life-years lost to HIV, and the mortality hazards of people living with HIV (PLHIV). Between 2000 and 2014, average adult life-years lived before age 50 increased significantly, from 26.4 to 33.5 years for all women and from 28.6 to 33.8 years for all men. As of 2014, life-years lost to HIV had declined significantly, to 1.3 years among women and 0.4 years among men. Following the roll-out of ART, mortality reductions among PLHIV were initially larger in women than men, but this is no longer the case.
