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.

Validation of self-reported male circumcision status and genital ulcer disease among Ugandan men.

OBJECTIVE: Voluntary medical male circumcision (MC) is a critical tool in combination HIV prevention programmes in Africa. Self-reported MC (SrMC) status is used in HIV epidemiological surveys to assess MC coverage but is subject to response bias with limited validation. This study evaluated the utility of SrMC status as a marker of MC as well as self-reported genital lesions for genital ulcer disease (GUD) among Ugandan men. METHODS: Male participants aged 18-49 years in the cross-sectional Sexually Transmitted Infection Prevalence study, conducted between May and October 2019, responded to a questionnaire capturing SrMC status and current genital ulcer symptoms followed by clinical assessment to verify MC and presence of GUD.Sensitivity, specificity, positive predictive value, negative predictive value and corresponding CIs (95% CI) for SrMC status and GUD were estimated. RESULTS: There were 853 male participants, of whom 470 (55.1%) self-reported being circumcised and 23 (2.7%) self-reported GUD (SrGUD). MC was clinically confirmed in 50.2% (n=428) of participants with sensitivity of SrMC status at 99% (95% CI: 98% to 100%) and specificity 89% (95% CI: 86% to 92%). Specificity of SrMC was lowest among persons living with HIV and viremic (>1000 copies/mL) at 72% (95% CI: 46% to 90%). 18 participants had clinically confirmed GUD, but only 12 SrGUD symptoms, corresponding to a sensitivity and specificity of 67% (95% CI: 41% to 87%) and 99% (95% CI: 98% to 99%), respectively. CONCLUSIONS: SrMC status is a robust proxy for clinically confirmed MC status and may reliably be used to assess MC coverage in this setting. Conversely, GUD symptoms were under-reported, which may impact effective syndromic management of sexually transmitted infections and warrants further examination.

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.

Age Patterns of HSV-2 Incidence and Prevalence in Two Ugandan Communities: A Catalytic Incidence Model Applied to Population-Based Seroprevalence Data.

BACKGROUND: Herpes simplex virus type 2 (HSV-2) is an incurable sexually transmitted infection associated with increased risk of acquiring and transmitting human immunodeficiency virus (HIV). HSV-2 is highly prevalent in sub-Saharan Africa, but population-level estimates of incidence are sparse. METHODS: We measured HSV-2 prevalence from cross-sectional serological data among adults aged 18-49 years in 2 south-central Uganda communities (fishing, inland). We identified risk factors for seropositivity, then inferred age patterns of HSV-2 with a Bayesian catalytic model. RESULTS: HSV-2 prevalence was 53.6% (n = 975/1819; 95% confidence interval, 51.3%-55.9%). Prevalence increased with age, was higher in the fishing community, and among women, reaching 93.6% (95% credible interval, 90.2%-96.6%) by age 49 years. Factors associated with HSV-2 seropositivity included more lifetime sexual partners, HIV positive status, and lower education. HSV-2 incidence peakied at age 18 years for women and 19-20 years for men. HIV prevalence was up to 10-fold higher in HSV-2-positive individuals. CONCLUSIONS: HSV-2 prevalence and incidence were extremely high, with most infections occurring in late adolescence. Interventions against HSV-2, such as future vaccines or therapeutics, must target young populations. Remarkably higher HIV prevalence among HSV-2-positive individuals underscores this population as a priority for HIV prevention.

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.

Using Population Mobility Patterns to Adapt COVID-19 Response Strategies in 3 East Africa Countries.

The COVID-19 pandemic spread between neighboring countries through land, water, and air travel. Since May 2020, ministries of health for the Democratic Republic of the Congo, Tanzania, and Uganda have sought to clarify population movement patterns to improve their disease surveillance and pandemic response efforts. Ministry of Health-led teams completed focus group discussions with participatory mapping using country-adapted Population Connectivity Across Borders toolkits. They analyzed the qualitative and spatial data to prioritize locations for enhanced COVID-19 surveillance, community outreach, and cross-border collaboration. Each country employed varying toolkit strategies, but all countries applied the results to adapt their national and binational communicable disease response strategies during the pandemic, although the Democratic Republic of the Congo used only the raw data rather than generating datasets and digitized products. This 3-country comparison highlights how governments create preparedness and response strategies adapted to their unique sociocultural and cross-border dynamics to strengthen global health security.

Severe Acute Respiratory Syndrome Coronavirus-2 seroprevalence in South-Central Uganda, during 2019-2021.

BACKGROUND: Globally, key subpopulations such as healthcare workers (HCW) may have a higher risk of contracting SARS-CoV-2. In Uganda, limited access to Personal Protective Equipment and lack of clarity on the extent/pattern of community spread may exacerbate this situation. The country established infection prevention/control measures such as lockdowns and proper hand hygiene. However, due to resource limitations and fatigue, compliance is low, posing continued onward transmission risk. This study aimed to describe extent of SARS-CoV-2 seroprevalence in selected populations within the Rakai region of Uganda. METHODS: From 30th November 2020 to 8th January 2021, we collected venous blood from 753 HCW at twenty-six health facilities in South-Central Uganda and from 227 population-cohort participants who reported specific COVID-19 like symptoms (fever, cough, loss of taste and appetite) in a prior phone-based survey conducted (between May and August 2020) during the first national lockdown. 636 plasma specimens collected from individuals considered high risk for SARS-CoV-2 infection, prior to the first confirmed COVID-19 case in Uganda were also retrieved. Specimens were tested for antibodies to SARS-CoV-2 using the CoronaChek™ rapid COVID-19 IgM/IgG lateral flow test assay. IgM only positive samples were confirmed using a chemiluminescent microparticle immunoassay (CMIA) (Architect AdviseDx SARS-CoV-2 IgM) which targets the spike protein. SARS-CoV-2 exposure was defined as either confirmed IgM, both IgM and IgG or sole IgG positivity. Overall seroprevalence in each participant group was estimated, adjusting for test performance. RESULTS: The seroprevalence of antibodies to SARS-CoV-2 in HCW was 26.7% [95%CI: 23.5, 29.8] with no difference by sex, age, or cadre. We observed no association between PPE use and seropositivity among exposed healthcare workers. Of the phone-based survey participants, 15.6% [95%CI: 10.9, 20.3] had antibodies to SARS-CoV-2, with no difference by HIV status, sex, age, or occupation. Among 636 plasma specimens collected prior to the first confirmed COVID-19 case, 2.3% [95%CI: 1.2, 3.5] were reactive. CONCLUSIONS: Findings suggest high seroprevalence of antibodies to SARS-CoV-2 among HCW and substantial exposure in persons presenting with specific COVID-19 like symptoms in the general population of South-Central Uganda. Based on current limitations in serological test confirmation, it remains unclear whether seroprevalence among plasma specimens collected prior to confirmation of the first COVID-19 case implies prior SARS-CoV-2 exposure in Uganda.

Cardiovascular (Framingham) and type II diabetes (Finnish Diabetes) risk scores: a qualitative study of local knowledge of diet, physical activity and body measurements in rural Rakai, Uganda.

BACKGROUND: Non-communicable diseases such as cardiovascular conditions and diabetes are rising in sub-Saharan Africa. Prevention strategies to mitigate non-communicable diseases include improving diet, physical activity, early diagnosis, and long-term management. Early identification of individuals at risk based on risk-score models - such as the Framingham Risk Score (FRS) for 10-year risk of cardiovascular disease and the Finnish type 2 Diabetes risk score (FINDRISC) for type 2 diabetes which are used in high-income settings - have not been well assessed in sub-Saharan Africa. The purpose of this study was to qualitatively assess local knowledge of components of these risk scores in a rural Ugandan setting. METHODS: Semi-structured qualitative in-depth interviews were conducted with a purposively selected sample of 15 participants who had responded to the FRS and FINDRISC questionnaires and procedures embedded in the Rakai Community Cohort Study. Data were summarized and categorized using content analysis, with support of Atlas.ti. RESULTS: Participants described local terms for hypertension ("pulessa") and type 2 diabetes ("sukaali"). Most participants understood physical activity as leisure physical activity, but when probed would also include physical activity linked to routine farm work. Vegetables were typically described as "plants", "leafy greens", and "side dish". Vegetable and fruit consumption was described as varying seasonally, with peak availability in December after the rainy season. Participants perceived themselves to have good knowledge about their family members' history of type 2 diabetes and hypertension. CONCLUSIONS: While most items of the FRS and FINDRISC were generally well understood, physical activity needs further clarification. It is important to consider the seasonality of fruits and vegetables, especially in rural resource-poor settings. Current risk scores will need to be locally adapted to estimate the 10-year risk of cardiovascular diseases and type 2 diabetes in this setting.

HIV status disclosure and antiretroviral therapy adherence among children in Masaka region, Uganda.

HIV-infected children are now living into adolescence and early adulthood in large numbers due to the availability and increased use of antiretroviral therapy (ART). However, receipt of HIV status disclosure among children remains low. We assessed the association between disclosure of HIV status and adherence to ART among children in the Masaka region of Uganda using multivariable logistic regression with generalised linear models with Poisson log-link function and robust variance in Stata software version 15.1. Data were collected from 524 assenting children aged 12-17 years between March and December 2020. Results show that, although not statistically significant, children who received disclosure of their HIV status reported improved ART adherence compared to children with no disclosure. Out-of-school children with post-primary education and children on first-line ART regimens were significantly more likely to report improved ART in both crude and adjusted analyses. Innovative interventions to promote progressive disclosure of HIV status to children on ART, in school, are needed to improve their ART adherence. There is also a need to evaluate the suitability of current counselling interventions provided to children being switched to second-line ART regimens to delay the need for third-line ART regimens.

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.

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.

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.

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.

Alcohol use in fishing communities and men's willingness to participate in an alcohol, violence and HIV risk reduction intervention: qualitative findings from Rakai, Uganda.

Alcohol use, intimate partner violence (IPV) and HIV infection are associated, but few programmes and interventions have addressed their synergistic relationship or been evaluated for effectiveness and acceptability. This is a critical gap in populations with high rates of alcohol use, HIV and IPV, such as Uganda's fishing communities. This study examined drinking norms, barriers and facilitators to engagement in a risk reduction programme, and ideas for tailoring. Results showed that alcohol use is common in fishing villages. While men and women drink, gendered notions of femininity deem alcohol largely unacceptable for women. Plastic sachets of liquor were the most common alcoholic drink. Participants did not understand the definition of 'hazardous drinking', but recognised connections between drinking, violence and sexual risk-taking. The idea of an alcohol, IPV and HIV risk reduction intervention was supported, but barriers need to be addressed, including how best to help those uninterested in reducing their drinking, addressing normalisation of drinking and how best to inform those who truly need intervention. Intervention to people living with HIV around the time of diagnosis and treatment may be warranted. Study findings highlight the potential to integrate alcohol and IPV reduction programmes into an HIV service provision.

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.

Women's role in male circumcision promotion in Rakai, Uganda.

Medical male circumcision (MMC) has expanded in sub-Saharan Africa, yet uptake remains sub-optimal. We sought to understand women's perceptions of and influence on MMC in Rakai, Uganda. We conducted in-depth interviews with 27 women in fishing and trading communities, including women married to circumcised and uncircumcised men, single women, and sex workers. Data analysis followed a team-based framework approach. All female participants preferred circumcised men because of perceived reduced HIV and sexually transmitted infection (STI) risk, improved penile hygiene, and increased sexual pleasure. Perceived negative aspects included abstinence during wound healing, potentially increased male sexual risk behaviors, fear of being blamed for HIV acquisition, and economic insecurity due to time off work. Participants felt women could persuade their partners to be circumcised, accompany them to the clinic, refuse sex with uncircumcised men, and participate in community MMC activities. Findings support women's important role in MMC acceptance.
