Objectives: To determine whether there is an association between alcohol use and unprotected intercourse (UI).
Methods: 122 individuals were recruited via posters in bars, on street posts, and via word of mouth to participate in an 8-week diary study. Participants were aged 19-35, unmarried, non- monogamous, and had consumed alcohol and had sex at least once per week. A quantitative diary was completed daily by individuals regarding all date, drinking/drug, and sexual events. Within-subject, event-based data were analyzed using multivariate GEE.
Results: 1173 sexual and 2789 drinking events were reported. Alcohol was consumed (within 1 hour/drink) prior to 43.2% of the sexual events. Condoms were used in 40.7% of intercourse events. Individuals were more likely to use condoms with repeat (OR=2.6) and first-time (OR=4.2) partners than with primary/committed partners (p<0.001). Controlling for individual and contextual factors in events with primary partners - alcohol inebriation was associated with UI (OR=2.35, p<0.05); however with "mastery" also included, alcohol use was no longer significant. With repeat partners, feeling the effects of beer lead to UI (OR=1.81, p<0.05); this was also not significant with "mastery" and "fatalism" included. With first-time partners, individuals with low impulse-control were more likely to have UI while inebriated (OR=1.78, p<0.05).
Conclusions: The effect of alcohol upon sexual activity is complex. Little evidence is found for the disinhibition hypothesis linking alcohol to unsafe sex. Issues specific to relationship type, personal resources and personality must be taken into consideration in tailoring messages and programs for young adults.
Learning Objectives: Participants will: 1) develop an understanding of the association between alcohol and unsafe sex 2) Reassess the importance of the disinhibition messages currently found in the alcohol and HIV prevention health promotion messages
