Objective: Adherence to combination antiretroviral therapy (ART) among pregnant women is essential to attaining the goal of eliminating mother-to-child HIV transmission. The objective of this study was to determine which factors affect adherence to ART among HIV-positive women enrolled in a large prevention of mother-to-child HIV transmission (PMTCT) trial in rural north-central Nigeria.
Methods: The parent study included 372 HIV-positive pregnant women enrolled in a cluster-randomized control trial conducted at 12 health facilities in Nigeria between 2013 and 2015. This secondary analysis included HIV-positive women (and their infants) from the original trial with documented adherence data (n=210, 56.5%). The primary outcome was maternal adherence to ART, determined by self-report and based on the visual analogue scale (VAS) of a validated medication adherence tool. Participants with a VAS score of ? 95% were classified as adherent. We employed multivariate logistic regression to evaluate the predictors of maternal ART adherence in the study sample.
Results: Approximately 61.0% of study participants (128/210) were adherent to ART. The majority of adherent participants (62.5%, 80/128) were enrolled in the trial intervention arm. The most common cited response for non-adherence was fear of status disclosure. Adherence to ART was associated with study arm (intervention arm vs. control arm, adjusted Odds Ratio (aOR) [95% CI]: 16.95 [5.30-54.23]), maternal ethnicity (Gwari vs. Other, aOR = 0.13 [0.05-0.38]), and partner HIV status (HIV-positive vs. unknown, aOR = 3.14 [1.22-8.07]).
Conclusion and Global Health Implications: Adherence to ART among a cohort of pregnant women enrolled in a PMTCT trial in rural North-Central Nigeria was associated with trial arm, maternal self- reported ethnicity, and partner
