Predictors of Longitudinal Trajectories of Alcohol Consumption in People with HIV.

BACKGROUND: To describe alcohol consumption trajectories in a cohort of People Living With HIV and determine clinical and sociodemographic predictors of each trajectory.

METHODS: This is a prospective cohort study of 7906 patients in the 7 Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) sites. Alcohol consumption was categorized as none, moderate, and alcohol misuse. Predictors included age, race/ethnicity, depressive or anxiety symptoms, illicit drug use (opioids, methamphetamines, cocaine/crack), marijuana use, hepatitis C virus (HCV) infection, HIV transmission risk factor, and HIV disease progression. We estimated sex-stratified alcohol consumption trajectories and their predictors.

RESULTS: We found 7 trajectories of alcohol consumption in men: stable non-drinking and increased drinking (71% and 29% of initial non-drinking); stable moderate, reduced drinking and increased alcohol misuse (59%, 21% and 21% of initial moderate alcohol use); and stable alcohol misuse and reduced alcohol misuse (75% and 25% of initial alcohol misuse). Categories were similar in women, except lack of an increase to alcohol misuse trajectory among women that begin with moderate use. Older men and women were more likely to have stable non-drinking, while younger men were more likely to increase to or remain in alcohol misuse. Minorities, people with depressive or anxiety symptoms, HCV-infected individuals and people who injected drugs were more likely to reduce use. Illicit drug use was associated with a reduction in overall drinking, while marijuana use was associated with stable moderate drinking or misuse.

CONCLUSIONS: Longitudinal trajectories of increasing alcohol use and stable misuse highlight the need to integrate routine screening and alcohol misuse interventions into HIV primary care. This article is protected by copyright. All rights reserved.
