Abstract:
BackgroundSex workers are disproportionately affected by HIV and sexually transmitted infections (STI) in the Republic of Congo. We conducted a one-group pre-post test participatory mapping (PM) intervention to increase HIV/STI testing uptake with female sex professionals (FSP) in Pointe Noire, Congo.MethodsWe engaged a peer-driven sample of FSP in Pointe Noire in a 2-day PM intervention. Voluntary HIV and STI testing and treatment was offered at Time 2 (T2) (directly post-intervention) until Time 3 (T3) (8-week post intervention). To measure HIV/STI testing changes between Time 1 (T1) (baseline, lifetime HIV/STI testing), T2, and T3, we used a generalized estimating equation model with robust standard errors, using an unstructured correlation matrix to account for within-subject correlations.ResultsAmong n = 99 participants (mean age: 25.5, standard deviation = 6.5), in analyses adjusted for age and sex work duration, there were significant increases at T2 in uptake of HIV testing (adjusted Odds Ratio [aOR] = 2.42; 95% CI = 1.31-4.48) and STI testing (aOR = 2.40; 95% CI = 1.27-4.54), as well as at T3 (HIV testing: aOR = 7.37; 95% CI = 2.82-19.23, STI testing: aOR = 5.88; 95% CI = 2.82-12.24), compared to baseline.ConclusionsFindings signal the promise of community-based approaches such as participatory mapping for increasing HIV/STI testing uptake with FSP in Pointe Noire.
