title: Binge drinking concurrent with anal intercourse and condom use among men who have sex with men.
abstract: Men who have sex with men (MSM) are the demographic group most severely affected by HIV in the USA. Global association studies have shown that MSM who binge drink are more likely to engage in risky sexual behaviors and day- and event-level analyses have linked binge drinking to sexual risk behavior on specific days and during specific sexual encounters. Despite this strong foundation of research, no studies have examined the association between the frequency of situational binge drinking (i.e., binge drinking concurrent with sexual activity) and aggregated sexual risk over periods of longer duration. We used multivariable logistic regression to assess the relationship between situational binge drinking (i.e., binge drinking concurrent with anal intercourse) and condomless anal intercourse (CAI) and among a cross-sectional sample of 124 MSM in San Francisco, CA. There was a positive relationship between frequency of situational binge drinking and CAI (1-5 times vs. never: adjusted odds ratio = 2.78, 95% CI = 1.01-7.63; 6-10 times vs. never: 6.19, 1.27-30.22; more than 10 times vs. never: 11.88, 1.31-107.60). By filling a methodological gap and complementing existing global and event-level analyses, this positive situational relationship strengthens the evidence linking binge drinking and sexual risk, enhances the comparability of the existing literature, and further suggests that the integration of dual strategies that aim to prevent HIV and reduce binge drinking may be warranted.
