title: Condom use among gay/bisexual male substance abusers using the timeline follow-back method.
abstract: Sexual risk for HIV transmission under the influence of alcohol and/or other drugs is not simply a cause-effect relationship: not everyone who drinks or uses other drugs has unprotected sex. The purpose of this study is to explore differences between substance using gay/bisexual men who use condoms during anal sex from those who do not. These differences are identified by comparing men whose anal sex while under the influence of alcohol and/or drugs is consistently protected to men whose anal sex while under the influence of alcohol and/or drugs is consistently unprotected. Gay/bisexual men entering substance abuse treatment at a gay-identified agency in San Francisco were recruited to complete surveys and to be interviewed about sexual behavior, substance use, and related variables using an extended version of the Timeline Follow-back (TL). The TL procedure uses a blank calendar form and a series of questions to cue recall of drinking, drug use, and anal intercourse on each of the 30 days prior to the last date of alcohol and/or drug use. Men whose anal sex while under the influence of alcohol and/or drugs is consistently unprotected were significantly more likely to report having less than a college education (p = .04), more likely to have an income of less than $20,000 (p = .01), more likely to use amyl nitrite (p = .01) and cocaine (p = .02), and more likely to report a higher frequency of anal sex (p = .007). In addition, they were less likely to approve of sex without love (p = .003), less likely to perceive that safer sex is the community norm (p < .001), and less likely to have encouragement from friends to practice safer sex (p = .001). However, HIV status did not differentiate between the two groups. These two groups provide clear and interesting contrasts in terms of behavior, thus comparisons of the factors influencing sexual safety in these subgroups may enhance our understanding of risk taking. A better understanding of possible mediating variables can be important both in guiding future research in this area and in formulating intervention strategies to target gay men who drink or use drugs in combination with sexual activity.
