Pre-exposure prophylaxis (PrEP) awareness, use, and discontinuation among Lake Victoria fisherfolk in Uganda
There is limited population-level data on the pre-exposure prophylaxis (PrEP) care continuum in eastern Africa. Here, we assessed the PrEP care continuum following PrEP rollout in a Ugandan community with ~40% HIV seroprevalence. We used cross-sectional population-based data collected between September 3 and December 19, 2018 from a Lake Victoria fishing community in southern Uganda to measure levels of self-reported PrEP awareness, ever-use, and…
Population-level coverage and correlates of enrollment in community-based antiretroviral therapy (ART) refill models following differentiated service delivery scale-up in Africa
Community-based antiretroviral therapy (ART) distribution is a promising strategy to increase HIV treatment accessibility in Africa, yet population-level coverage and correlates of enrollment are understudied. We pooled data from seven Population-based HIV Impact Assessment surveys (2020–2023) and used survey-weighted multivariable logistic regression with jackknife variance estimation to identify socio-demographic and clinical correlates of enro…
HIV provider perspectives on opioid use disorder care integration into outpatient HIV care in Baltimore, Maryland
Despite the high prevalence of opioid use disorders (OUD) among people with HIV (PWH), treatment among PWH remains low. Integrating OUD care into HIV care may improve OUD outcomes; however, adoption is limited due to multilevel barriers. RESTORE is a low-threshold substance use disorder (SUD) care program integrated into an outpatient HIV-care clinic that provides training and ongoing support for SUD care adoption by HIV providers. This mixed-met…
It makes all the sense in the world”
HIV epidemiologic trends among occupational groups in Rakai, Uganda
Certain occupations have been associated with heightened risk of HIV acquisition and spread in sub-Saharan Africa, including female bar and restaurant work and male transportation work. However, data on changes in population prevalence of HIV infection and HIV incidence within occupations following mass scale-up of African HIV treatment and prevention programs is very limited. We evaluated prospective data collected between 1999 and 2016 from the…
Use of mobile phones to collect data on Covid-19
During the COVID-19 pandemic lockdown, we deployed a rapid, mobile phone-based survey to assess access and participation rates when using mobile phones to collect data on COVID-19 in Rakai, south-central Uganda. We sampled prior Rakai Community Cohort Study (RCCS) participants based on HIV status using mobile phone contacts. We administered a 30-minute phone-based interview to consenting participants to assess their knowledge about different aspe…
Motivational interviewing experiences from a community health worker-led HIV prevention and care intervention in rural Uganda
Motivational Interviewing (MI) and Community Health Workers (CHWs) are increasingly utilized in global settings to improve HIV outcomes, yet research exploring implementation strategies using MI and CHWs is lacking. We examined the experiences of CHWs and their clients in a counseling intervention which used MI-informed counseling to increase engagement in HIV prevention and treatment. This study was nested within the mLAKE cluster-randomized tri…
From ‘no problem’ to ‘a lot of difficulties’
Migration is increasingly common in Africa, especially for employment. Migrants may face additional barriers to accessing health care, including human immunodeficiency virus (HIV) prevention and treatment, compared with long-term residents. Exploring migrants’ experiences with health services can provide insights to inform the design of health programmes. In this study, we used qualitative methods to understand migrants’ barriers to health servic…
Overweight and obesity in south central Uganda
Obesity is a rapidly growing global health challenge, but there are few population-level studies from non-urban settings in sub-Saharan Africa. We evaluated the prevalence of overweight (body mass index (BMI)>25 kg/m 2 ), obesity (BMI>30 kg/m 2 ), and associated factors using data from May 2018 to November 2020 from the Rakai Community Cohort Study, a population-based cohort of residents aged 15 to 49 living in forty-one fishing, trading, and agr…
Sex is supposed to be naturally more pleasurable
Global health researchers often approach Traditional, Complementary, and Alternative Medicine (TCAM) from a health efficacy perspective, asking whether the presence of plural medical systems helps or hinders the uptake of biomedicine. Medical anthropologists, by contrast, typically emphasize how plural medical systems encourage us to rethink health ontologies-that is, who and what comes to constitute the experience of health and illness, and thro…
Qualitative Assessment of Barriers and Facilitators of PrEP Use Before and After Rollout of a PrEP Program for Priority Populations in South-central Uganda
HIV Prevention and Treatment Behavior Change and the Situated Information Motivation Behavioral Skills (sIMB) Model
Community-Driven Priorities in Smartphone Application Development
Social networks have the potential to enhance Type 2 Diabetes Mellitus (T2DM) self-management. We used qualitative methods to study if and how mobile application (app) functions that mobilize social resources to improve T2DM management would be desired in a low-income African American community. Data were collected through community discussions and in-depth interviews with 78 participants in 2016-2018. Participants included individuals with self-…

Effectiveness of Peer Support on Care Engagement and Preventive Care Intervention Utilization Among Pre-antiretroviral Therapy, HIV-Infected Adults in Rakai, Uganda
Perceptions and acceptability of mHealth interventions for improving patient care at a community-based HIV/Aids clinic in Uganda
Mobile technologies for health (mHealth) represents a growing array of tools being applied in diverse health care settings. mHealth interventions for improving HIV/AIDS care is a promising strategy, but its evidence base is limited. We conducted a formative research evaluation to inform the development of novel mHealth HIV/AIDS care interventions to be used by community health workers (CHWs) in Kampala, Uganda. A mixed methods formative research …
Cost analyses of peer health worker and mHealth support interventions for improving Aids care in Rakai, Uganda
A cost analysis study calculates resources needed to deliver an intervention and can provide useful information on affordability for service providers and policy-makers. We conducted cost analyses of both a peer health worker (PHW) and a mHealth (mobile phone) support intervention. Excluding supervisory staffing costs, total yearly costs for the PHW intervention was $8475, resulting in a yearly cost per patient of $8.74, per virologic failure ave…
Guidelines for Improving Entry Into and Retention in Care and Antiretroviral Adherence for Persons With HIV
DESCRIPTION: After HIV diagnosis, timely entry into HIV medical care and retention in that care are essential to the provision of effective antiretroviral therapy (ART). Adherence to ART is among the key determinants of successful HIV treatment outcome and is essential to minimize the emergence of drug resistance. The International Association of Physicians in AIDS Care convened a panel to develop evidence-based recommendations to optimize entry …
The organization and implementation of community-based education programs for health worker training institutions in Uganda
BACKGROUND: Community-based education (CBE) is part of the training curriculum for most health workers in Uganda. Most programs have a stated purpose of strengthening clinical skills, medical knowledge, communication skills, community orientation of graduates, and encouragement of graduates to work in rural areas. This study was undertaken to assess the scope and nature of community-based education for various health worker cadres in Uganda. METH…
Perception and valuations of community-based education and service by alumni at Makerere University College of Health Sciences
BACKGROUND: Training of health professionals can be deliberately structured to enhance rural recruitment by exposing the trainees to the realities of rural life and practice through Community-Based Education and Service (COBE) programs. Few studies have surveyed the alumni of these programs to establish their post-university views and whether the positive impact of COBE programs endures into the post-university life. This study surveyed the alumn…
