Identifying Factors Associated with Low-Adherence and Subsequent HIV Seroconversions Among South African Women...

Sub-Saharan Africa has the highest number of HIV infected individuals in the world. Developing and implementing effective biomedical interventions still remains urgent. Poor adherence has been commonly identified as one of the major barriers for the success of HIV prevention trials. A better understanding of how to improve adherence remains a research priority. In this analysis, younger age (<35 years), number of children ≤2, being single/not cohabiting and having a new partner during the study follow up were all significantly associated with poor adherence and subsequent HIV seroconversions. At population level, these three factors collectively associated with 56 % of the low level adherence and 75 % of the HIV seroconversions. Results highlighted the importance of effective adherence and comprehensive contraceptive counselling of women who enrol in HIV prevention trials. Culturally and socially appropriate methods are needed to achieve and maintain optimum adherence levels in future HIV prevention research.
