Factors associated with uptake of dual contraception among HIV-infected women in Bungoma County, Kenya: a cross-sectional study

Introduction: dual contraception, the use of non-barrier contraceptive method in combination with condoms, is an effective strategy in the elimination of mother-to-child transmission (eMTCT) of human immunodeficiency virus (HIV) and the achievement of zero new HIV infections. Despite its effectiveness, dual contraception use among HIV-infected women in Kenya remains low. We identified factors associated with dual contraceptive uptake in Bungoma County, Kenya. Methods: this was a facility-based cross-sectional study in eight hospitals in Bungoma County. We interviewed women using structured questionnaires. We calculated descriptive statistics about the womens' baseline characteristics, examined the association between dual contraceptive use and other factors by calculating Odds Ratios (OR) and 95% Confidence Intervals (CI) and performed logistic regression. Results: we recruited 283 HIV-infected women.Among all enrolled women, 190 (67.1%) were aware of dual method and only 109 (38.5%) used dual contraception. The preferred dual pattern was male condom plus injectable contraceptive used by 53.2% of women (58/109). Among the 174 women who did not use dual contraception, 86 (49.4%) preferred using male condoms alone for contraception. Women were more likely to use dual contraception method if they were aware of dual contraception (AOR 12.2, 95% CI 4.7 - 31.7), used non-barrier contraceptives (AOR 9.8 95%; CI 4.5 - 21.3) and had disclosed their HIV status (AOR 7.1 95% CI 2.8 - 18.2) compared to those who did not. Conclusion: dual contraceptive prevalence was low. Advocacy on dual contraception as an approach to preventing vertical transmission of HIV should be escalated in order to improve its uptake.
