Poster Abstract
Abstract
Background
Sexually transmitted infections (STIs), including infection with the human immunodeficiency virus (HIV), continue to be a large public health burden among men MSM. HRSB are potentially destructive behaviors, engaged in voluntarily, regardless of the level of understanding, if any, of possible adverse consequences. HRSB encompass activities that increase the odds of developing an STI, including infection with HIV, such as [any alcohol use/heavy episodic drinking].
.
Objectives
To review, classify, and critique peer-reviewed publications analyzing measures related to alcohol use and risky sexual behaviors among MSM populations. The primary objective of this study is to estimate the total effect size of [any alcohol use/heavy episodic drinking] onto four risky sexual behaviors, namely: condomless anal intercourse (insertive, receptive, or any), condomless oral intercourse, multiple sexual partners, and transactional sex.

Methods
We searched PubMed, EMBASE, PsycINFO, LGBT Life, Web of Science, SCOPUS, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from their inception to 2016. Articles published in any language, with full English abstracts were eligible for inclusion. Our statistical analysis of the four primary measures of risky sexual behaviors among MSM included two steps: (1) identification of data sources and documenting estimates and (2) application of Cochrane Collaboration’s random-effects meta-analysis model to aggregate odds/risk ratios estimates and account for between-study variability in calculating the overall pooled estimates and 95% CI for [any alcohol use/heavy episodic drinking]. We derived standard errors where studies have provided the corresponding numerator and denominator for the odds/risk ratios estimates. We considered nonoverlapping CIs as an indication of statistically significant differences.

Results
Of the 6 studies included in the final analysis, 2 were cohort studies, 2 cross-sectional, 1 randomized controlled trial, and 1 case-control.
Of the 6 studies, 3 had situational association, 2 were globally associated, and 1 was associated by event.
Generally, reports of condomless risky sexual behaviors increased as heavy episodic binge drinking increased
