Heavy drinking trajectories among men who have sex with men: a longitudinal, group-based analysis.

ABSTRACT:

Background

Heavy episodic drinking (HED) is associated with sexual risk behavior and HIV seroconversion among men who have sex with men (MSM), yet few studies have examined heavy drinking typologies in this population.

Methods

We analyzed data from 4,075 HIV-uninfected MSM (aged 16 to 88) participating in EXPLORE, a 48-month behavioral intervention trial, to determine the patterns and predictors of HED trajectories. HED was defined as the number of days in which ≥5 alcohol drinks were consumed in the past 6 months. Longitudinal group-based mixture models were used to identify HED trajectories, and multinomial logistic regression was used to determine correlates of membership in each group.

Results

We identified 5 distinct HED trajectories: nonheavy drinkers (31.9%); i
