Abstract

Antiretroviral adherence in the postpartum period is crucial for maternal health and decreasing the risk of mother-to-child HIV transmission and transmission to sexual partners. Self-reported antiretroviral adherence was examined between 6- to 12-weeks and 30 months postpartum among 270 HIV-infected women enrolled in a prospective cohort study from 2008 to 2010 at multiple sites in Latin America. Adherence data were collected at each study visit to quantify the proportion of prescribed antiretrovirals taken during the previous three days, assess the timing of the last missed dose, and identify predictors of adherence. Mean adherence rates were 89.5% at 6–12 weeks and 92.4% at 30 months; the proportions with perfect adherence were 80.3% and 83.6%, respectively. The overall trend for perfect adherence was not significant (p = 0.71). In adjusted regression modelling, younger age was associated with an increased probability of non-perfect adherence at 18 and 24 months postpartum. Other factors associated with increased probability of non-perfect adherence were higher parity, current use of alcohol and tobacco, and more advanced HIV disease. Women with perfect adherence had lower viral loads. Interventions for alcohol and tobacco use cessation, and support for young women and those with advanced HIV disease should be considered to improve postpartum adherence.
