Alignment of PrEP use and effective contraceptive use among East African women in HIV serodiscordant partnerships.

Women who have a prevention mindset may opt for concurrent use of oral pre-exposure prophylaxis (PrEP) and all forms of contraception; we therefore assessed how contraception may influence PrEP use or vice versa. We analyzed data from Kenyan and Ugandan HIV-uninfected non-pregnant women in sero-discordant partnerships who were participating in the Partners Demonstration Project. Using multivariable generalized estimating equation models, we estimated the associations between effective contraceptive use and 1) PrEP dispensation 2) high effective PrEP use. Among the 311 women (93.1% of all those followed in the Partners Demonstration Project) median age was 29 years (interquartile range [IQR] 24.0-35.0) and 115 (37.0%) reported using effective contraception at baseline. All the women initiated PrEP during the study and moderately high PrEP adherence was recorded at 73.1% of visits over an average 7.5 months following PrEP dispensation. Women (14.8%) consistently used an effective contraceptive throughout study follow-up. PrEP dispensation was more frequent among those concurrently using effective contraception, (adjusted relative risk [aRR] = 1.19; 95% confidence interval [CI] = 1.08-1.32) and contraceptive use was more common among those on PrEP (aRR = 1.63; 95% CI = 1.18-2.25). Among East African women at high risk of HIV infection, PrEP dispensation was more frequent among women using effective contraception, indicating that family planning outlets may be efficient locations to deliver PrEP.
