We assessed the ability to recruit and retain individuals from fishing communities into an HIV vaccine preparedness cohort study in Masaka, Uganda.Methods HIV high risk, sero-negative adults (18-49 years) were identified from four fishing villages bordering Lake Victoria through door-to-door HIV counselling and testing (HCT). Interested persons were referred for: screening, enrolment, and quarterly follow-up visits at a study clinic located approximately 40 kilometres away. Repeat HCT, HIV risk assessment, and evaluation and treatment for sexually transmitted infections were provided. Rates of and factors associated with study dropout were assessed using Poisson regression models.Results A total of 940 participants were screened between January 2012 and February 2015, of whom 654 were considered for the analysis. Over a two-year follow-up period, 197 (30.1%) participants dropped out of the study over 778.9 person-years, a dropout rate of 25.3 / 100 person-years. Dropout was associated with being female (aRR =1.56, 95% confidence interval [CI] 1.12-2.18), age, being 18-24 years (aRR=1.64; 95% CI 1.03-2.60), 25-34 years (aRR=1.63; 95% CI 1.04-2.55); having no education (aRR=2.02; 95% CI: 1.23-3.31); living in the community for less than one year (aRR=2.22; 95% CI: 1.46-3.38) or 1-5 years (aRR=1.68; 95% CI: 1.16-2.45) and occupation.Conclusions It is possible to recruit and retain individuals from fishing communities, however, intensified participant tracing may be necessary in a vaccine trial to keep in follow up female, young, less educated, those in mobile occupations and new residents.
