Binge drinking is associated with differences in weekday and weekend adherence in HIV-infected individuals.

ABSTRACT: 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.

Project description:INTRODUCTION:Older adults are generally considered to be at greater risk for medication non-adherence due to factors such as medication complexity, side effects, cost, and cognitive decline. However, this generalization may not apply to older adults with human immunodeficiency virus (HIV). Regardless of age, suboptimal adherence to antiretroviral therapy (ART) can lead to increased viral load, immunosuppression, drug-resistant viral strains, co-morbidities, and opportunistic infections. Understanding trends of adherence to ART among older adults is critical, especially as the population of people living with HIV grows older. OBJECTIVES:The purpose of this systematic review and meta-analysis is to determine if older individuals with HIV are less likely to be non-adherent to antiretroviral therapy than younger individuals with HIV. DESIGN:A systematic search in PubMed, Embase, and PsycINFO was conducted to identify peer-reviewed articles evaluating adherence to ART in older adults. Two independent reviewers screened abstracts, applied inclusion criteria, and appraised study quality. The bibliographies of qualifying studies were searched. Data were abstracted from studies by two independent authors. Meta-analyses were conducted, and adherence levels were reported as the relative risk of non-adherence in older individuals compared to younger individuals. RESULTS:The systematic search yielded 1,848 abstracts. Twelve studies met full inclusion criteria. The overall meta-analysis found that older age reduced risk for nonadherence by 27 % (relative risk (RR) 0.72, 95 % confidence interval (CI) 0.64–0.82). Studies assessing both short-term and long-term adherence demonstrated a significant reduction in non-adherence among older patients (RR 0.75, 95 % CI 0.64–0.87 and RR 0.65, 95 % CI 0.50–0.85, respectively). CONCLUSIONS:Older adults with HIV have a reduced risk for non-adherence to ART than their younger counterparts. Future studies should seek to elucidate contributing factors of adherence among older individuals with HIV.
