Alcohol use among HIV-positive women of childbearing age, United States, 2013–2014

Abstract

ABSTRACT More than one-quarter of the adults living with diagnosed HIV infection in the US are women. Binge drinking (i.e., ≥4 alcoholic drinks per occasion for women) is associated with poor HIV treatment compliance, HIV incidence, and unplanned pregnancy. However, little is known about the prevalence of binge drinking among women of childbearing age who are living with HIV (WLWH) and health risk behaviours among those who binge drink. Using the 2013–2014 data cycles of Medical Monitoring Project, we assessed the weighted prevalence of drinking patterns by socio-demographic, clinical and reproductive characteristics of 946 WLWH. Logistic regression was used to calculate unadjusted and adjusted prevalence ratios and 95% confidence intervals. Overall, 39% of WLWH reported current drinking and 10% reported binge drinking. Compared to non-drinkers, binge drinkers were less likely to adhere to antiretroviral therapy (ART) or be virally suppressed. In multivariate analyses, binge drinking among WLWH was associated with smoking, drug use, and reduced ART adherence compared to non-drinkers, increasing the likelihood of negative clinical outcomes. WLWH may benefit from a comprehensive approach to reducing binge drinking including alcohol screening and brief interventions and evidence-based policy strategies that could potentially improve adherence to HIV treatment.
