dc.description.abstractUnderstanding the extent to which HIV burden diff ers across communities and the drivers of lo cal disparities is crucial for an eff ective and targeted HIV response. We assessed community-level variations in HIV prevalence, risk factors, and treatment and prevention service uptake in Rakai, Uganda. Methods The Rakai Community Cohort Study (RCCS) is an open, population-based cohort of people aged 15–49 years in 40 communities. Participants are HIV tested and interviewed to obtain sociodemographic, behavioural, and health information. RCCS data from Aug 10, 2011, to May 30, 2013, were used to classify communities as agrarian (n=27), trading (n=9), or lakeside fi shing sites (n=4). We mapped HIV prevalence with Bayesian methods, and characterised variability across and within community classifi cations. We also assessed diff erences in HIV risk factors and uptake of antiretroviral therapy and male circumcision between community types. Findings 17 119 individuals were included, 9215 (54%) of whom were female. 9931 participants resided in agrarian, 3318 in trading, and 3870 in fi shing communities. Median HIV prevalence was higher in fi shing communities (42%, range 38–43) than in trading (17%, 11–21) and agrarian communities (14%, 9–26). Antiretroviral therapy use was signifi cantly lower in both men and women in fi shing communities than in trading (age-adjusted prevalence risk ratio in men 0·64, 95% CI 0·44–0·97; women 0·53, 0·42–0·66) and agrarian communities (men 0·55, 0·42–0·72; women 0·65, 0·54–0·79), as was circumcision coverage among men (vs trading 0·48, 0·42–0·55; vs agrarian 0·64, 0·56–0·72). Self-reported risk behaviours were signifi cantly higher in men than in women and in fi shing communities than in other community types. Interpretation Substantial heterogeneity in HIV prevalence, risk factors, and service uptake in Rakai, Uganda, emphasises the need for local surveillance and the design of targeted HIV responses. High HIV burden, risk behaviours, and low use of combination HIV prevention in fi shing communities make these populations a priority for intervention.
