Resumen
Background—Understanding patterns of antiretroviral adherence and its predictors is important for designing tailored interventions. Alcohol use is associated with non-adherence. This study aimed to evaluate: 1) if there was a difference in weekday compared with weekend adherence in
HIV-infected individuals from low and middle income countries (LMIC), and 2) whether binge drinking was associated with this difference. Methods—Data from a randomized trial conducted at 9 sites in 8 LMIC were analyzed.
Microelectronic monitors were used to measure adherence. Differences between weekday and weekend adherence in each quarter (successive 12-week periods) were compared using Wilcoxon signed rank tests and predictors of adherence, including baseline binge drinking, were evaluated
using Generalized Estimating Equations. Results—Data from 255 participants were analyzed: 49.8% were male, median age was 37 years
and 28.6% enrolled in Haiti. At study entry, only 2.7% reported illicit substance use, but 22.3% reported binge drinking at least once in the 30 days prior to enrollment. Adherence was higher on weekdays than weekends (median percent doses taken: 96.0% vs 94.4%; 93.7% vs 91.7%; 92.6% vs 89.7% and 93.7% vs 89.7% in quarters 1–4 respectively, all p<0.001). Binge drinking at baseline and time on study were both associated with greater differences between weekday and weekend adherence. Conclusions—Adherence was worse on weekends compared to weekdays: difference was small at treatment initiation, increased over time and was associated with binge drinking. Screening and new interventions to address binge drinking, a potentially modifiable behavior, may improve
adherence in HIV-infected individuals in LMIC.
