Influence of alcohol-serving venue characteristics on yield of HIV status-neutral screening in rural East Africa
Alcohol-serving venues are high-risk sites for HIV transmission in East Africa. Understanding how venue characteristics influence HIV screening outcomes may help to target venue-based outreach. In eight rural communities in Kenya and Uganda, we mapped all alcohol-serving venues (N = 530) and invited owners to participate in a cluster-randomized trial to promote biomedical HIV prevention uptake: 527 (99%) owners agreed to participate. We distribut…
Association Between Alcohol Use, CD4 Count, and Depressive Symptoms Among People with HIV with Viral Load Suppressed in Southwestern Uganda
Despite the current effective antiretroviral therapy (ART) and viral suppression, depression remains the most prevalent mental health challenge among people with HIV (PWH) in Uganda and worldwide. This study examined the relationship between CD4 cell count and depressive symptoms among PWH on ART with viral suppression, and the potential modification effect of alcohol use on this relationship. We combined baseline data from two longitudinal studi…
Perceived benefits of community-based TB preventive treatment in children in Uganda
Tuberculosis preventive treatment (TPT) uptake among children at risk for TB remains low in sub-Saharan Africa. Community-based TPT delivery is effective at increasing uptake and completion in children compared to clinic-based models, but implementation research is needed to inform scale-up in real-world settings. In this qualitative study, we assessed community and health care provider perspectives on the anticipated benefits and barriers of a c…
Association between Levels of Alcohol Use, Perceived HIV Risk, and Untreated HIV Among Persons at Alcohol-Serving Venues in Kenya and Uganda
Alcohol-serving venues in East Africa are high-risk environments for HIV transmission but few studies in sub-Saharan Africa (SSA) have examined perceived HIV risk and sexual risk behaviors by alcohol use levels on a broader population of persons at alcohol-serving venues in the era of biomedical HIV prevention. We conducted a cross-sectional analysis of adults (≥ 18 years) at alcohol-serving venues in eight communities (~ 10,000 residents/communi…
Doing more with less
Community-based organizations (CBOs) played a key role in providing health and safety net support to low-income Latino communities during the COVID-19 pandemic; yet we know little about how organizations navigated challenges during this time. Understanding how CBOs navigate challenging periods is critical to ensuring a robust safety net for Latino and other underserved populations. We examined the factors that allowed CBOs to address Latino commu…
Metrics of Mobility by Sex are Associated with HIV Incidence in Rural Kenya and Uganda
The complex and dynamic nature of human mobility requires use of multiple measures and sex-stratified analyses to fully understand its influence on HIV acquisition risk in specific populations and settings. Longitudinal population-based studies designed to measure the influence of mobility (which includes both short and long-term, temporary and permanent changes of residence across defined geopolitical boundaries) on HIV acquisition risk are rare…
Participant perspectives on incentives for TB preventative therapy adherence and reduced alcohol use
Economic incentives to promote health behavior change are highly efficacious for substance use disorders as well as increased medication adherence. Knowledge about participants’ experiences with and perceptions of incentives is needed to understand their mechanisms of action and optimize future incentive-based interventions. The Drinkers’ Intervention to Prevent Tuberculosis (DIPT) trial enrolled people with HIV (PWH) in Uganda with latent tuberc…
Five lessons from a mid-level health manager intervention to increase uptake of tuberculosis prevention therapy in Uganda
BACKGROUND: Leadership skills are essential for middle-level healthcare manager efficacy. Capacity-building efforts may attempt behavioural change by filling 'knowledge gaps' while neglecting a sustainable application of that knowledge. Sustainable application of that knowledge, or implementation know-how, must resonate with local cultural patterns. When it is neglected, root issues like unclear decision-making space and local authority to interp…
Psychometric assessment of the Runyankole-translated Marlowe-Crowne Social Desirability Scale among persons with HIV in Uganda
We detected and mitigated measurement error in the 28-item Runyankole-translated SDS, and found that the modified 27-item scale had satisfactory construct validity and internal consistency in our sample. Future studies should continue to evaluate the psychometric properties of the Runyankole-translated SDS, including retranslating Item 14 and reevaluating its performance
Lessons from Two Latino Communities Working with Academic Partners to Increase Access to Covid-19 Testing
Objective: We sought to examine the experiences of community partners in a community–academic partnership to promote COVID-19 testing in two majority Latino communities. Methods: We conducted semistructured, in-depth interviews in English and Spanish with community-based organization leaders and community health workers/ promotoras ( n = 10) from June to July 2021. Interviews focused on identifying partner roles in planning and testing implementa…
Lessons from Two Latino Communities Working with Academic Partners to Increase Access to Covid-19 Testing
Community-academic partnerships that invest in strong relationships, community leadership, and a commitment to the community's preferred language offer a promising approach to addressing COVID-19 testing barriers. Findings provide direction for future research on how community members and academic partners can come together to inform strategies to continue addressing the COVID-19 pandemic
A Qualitative Exploration of Intimate Partner Violence Among HIV/TB Coinfected Persons With Problematic Alcohol Use Participating in an Incentive-Based Alcohol/Medication Adherence Intervention in Uga…
In Uganda, four in ten women report experiencing intimate partner violence (IPV) in the past year. Salient drivers of IPV in sub-Saharan Africa include stress related to household finances, alcohol use, and partner infidelity. We conducted 42 interviews with participants ( n = 32) in the Drinkers' Intervention to Prevent Tuberculosis (DIPT) study which included economic incentives, and their partners ( n = 10) to understand how participating in D…

Feasibility and preliminary effectiveness of integrating HIV prevention into an adolescent empowerment and livelihood intervention at youth clubs in rural Uganda
The uptake of HIV prevention services is lower among youth than adults in sub-Saharan Africa. Existing youth livelihood trainings offer a potential entry point to HIV prevention services. We determined feasibility and preliminary effectiveness of integrating HIV prevention into youth clubs implementing an empowerment and livelihood for adolescents (ELA) intervention in rural Uganda. Staff conducted community mobilization for youth (15-24 years) o…
Effects of a Covid-19 Public Health Lockdown on Drinking and Health Behavior Among Persons with HIV and with Unhealthy Alcohol use in Uganda
To better understand the impact of Uganda’s initial COVID-19 lockdown on alcohol use, we conducted a cross-sectional survey (August 2020-September 2021) among persons with HIV (PWH) with unhealthy alcohol use (but not receiving an alcohol intervention), enrolled in a trial of incentives to reduce alcohol use and improve isoniazid preventive therapy. We examined associations between bar-based drinking and decreased alcohol use, and decreased alcoh…
Unhealthy alcohol use and intimate partner violence among men and women living with HIV in Uganda
Prevalence of IPV victimization was comparable to estimates from a recent national survey, while perpetration among men was lower than expected. Alcohol use level was not associated with IPV victimization. It is possible that alcohol use in this sample was too high to detect differences in IPV. Our results suggest that women and younger PWH are priority populations for IPV prevention

High Parental Vaccine Motivation at a Neighborhood-Based Vaccine and Testing Site Serving a Predominantly Latinx Community
Purpose: To understand vaccine attitudes of Latinx parents highly impacted by COVID-19. Methods: In April 2021, we surveyed parents about their attitudes for COVID-19 vaccination of their children at a community-based outdoor testing/vaccination site serving predominantly low-income Latinx persons in San Francisco. Results: Among 1033 parents (75% Latinx), 92% would “definitely” or “probably” vaccinate their children. Vaccine concerns were higher…
HIV retesting and risk behaviors among high-risk, HIV-uninfected adults in Uganda
There are limited data characterizing HIV retesting among high-risk adults in sub-Saharan Africa. From October-December 2018, we distributed recruitment cards offering health evaluations with HIV testing at venues frequented by individuals at-risk of HIV infection in Southwest Uganda. Those who attended were asked about their HIV testing history and risk factors: having >1 sexual partner, an HIV+ partner, STIs, and/or transactional sex. We define…
Planning prompts to promote uptake of HIV services among men
INTRODUCTION: Interventions informed by behavioural economics, such as planning prompts, have the potential to increase HIV testing at minimal or no cost. Planning prompts have not been previously evaluated for HIV testing uptake. We conducted a randomised clinical trial to evaluate the effectiveness of low-cost planning prompts to promote HIV testing among men. METHODS: We randomised adult men in rural Ugandan parishes to receive a calendar plan…
Predictors of isoniazid preventive therapy completion among HIV-infected patients receiving differentiated and non-differentiated HIV care in rural Uganda
Rates of Isoniazid Preventive Therapy (IPT) completion remain low in programmatic settings in sub-Saharan Africa. Differentiated HIV care models may improve IPT completion by addressing joint barriers to IPT and HIV treatment. However, the impact of differentiated care on IPT completion remains unknown. In a cross-sectional study of people with HIV on antiretroviral therapy in 5 communities in rural Uganda, we compared IPT completion between pati…

Men “missing” from population-based HIV testing
Men's uptake of HIV testing is critical to the success of "test and treat" strategies in generalized epidemics. This study sought to identify cultural factors and community processes that influence men's HIV testing uptake in the baseline year of an ongoing test-and-treat trial among 334,479 persons in eastern Africa (SEARCH, NCT#01864603). Data were collected using participant observation at mobile community health campaigns (CHCs) (n = 28); foc…
