Risk behavior for HIV transmission among gay men surveyed in Seattle bars.

Men attending four Seattle gay bars were asked to complete a self-administered questionnaire including measures of sexual behavior, perceptions of peer norms in the area of sexual safety, personal human immunodeficiency virus (HIV) risk estimate, and knowledge and use of a variety of acquired immunodeficiency syndrome (AIDS) prevention services. Twenty-nine percent of the sample reported engaging in unprotected anal intercourse at least once during the 2 months before the survey. Differences in peer norm perceptions, age, HIV risk estimate, and intent to be sexually safe in the future were found between those engaging in unprotected anal intercourse and those not reporting unprotected anal intercourse. No significant differences were found in level of education, use of AIDS prevention services, and whether or not a person had been tested for HIV. Implications for prevention programs are discussed.
