Introduction Pregnant women in sub-Saharan Africa represent a high-risk group for HIV infection, but most endemic countries including Uganda do not engage specific HIV prevention measures in pregnancy. This longitudinal study aimed to assess outcomes of a comprehensive, ANC-embedded strategy to prevent seroconversions during pregnancy in Western Uganda. Methods HIV-negative ANC clients were administered an HIV risk assessment tool, followed by individual risk counselling. They received a fixed

... ppointment for repeat HIV testing after three months. Those attending ANC without partners obtained formal partner invitation letters. At follow-up after three months, women not attending repeat testing were reminded via text message. Post-intervention risk behavior engagement was captured. We analyzed uptake of the intervention, HIV incidence rate, and associations with risk behavior. Results Of 1081 participants, 116 (10.7%) reported risk behavior engagement at first ANC visit, 148/1081 (13.7%) were accompanied by partners. The repeat test visit was attended by 848/1081 (78.5%) women, 42 (5.0%, p < 0.001) reported post-intervention risk behavior engagement, and 248 (29.4%, p < 0.001) were accompanied by partners. Seroconversion occurred in two women. In multivariable logistic regression, rural facility clients compared to urban ones (aOR 3.96; 95%CI 1.53-10.26), and women with positive or unknown partner HIV-status (aOR 2.86; 1.18-6.91) and partner alcohol abuse (aOR 2.68; 1.15-6.26) had increased odds for engagement in risk behavior despite the intervention. Conclusions After our intervention, risk behavior in pregnancy was reduced by half, and partner attendance had doubled compared to baseline. Our cohort showed a 0.76/100 women-years HIV incidence rate compared to 2.85 in pre-intervention data from the same setting. Clients from rural settings and women experiencing precarious partner situations require special attention to reduce risk behavior engagement during pregnancy. Key messages • HIV incidence in pregnancy in Western Uganda can be significantly reduced through a comprehensive, ANC-based counselling intervention. • Pregnant women from rural settings and those experiencing precarious partner situations require special attention regarding sexual risk behavior.
