The objectives of this study were to determine predictors of consistent condom use in heterosexual relationships of young adults who use hard drugs in a neighbourhood with widespread drug-use-connected HIV. We interviewed 196 18-24 year olds who injected drugs or used heroin, cocaine or crack in the prior year and lived in the Bushwick neighbourhood of New York City. Interviews covered sociodemographics, substance use and sexual networks. The unit of analysis is the relationship; the dependent variable measures consistent condom use over the prior 30 days in a given relationship. Consistent condom use was reported in 26% of 377 non-commercial relationships and in all of 22 commercial relationships. Using multiple logistic regression, consistent condom use in non-commercial relationships was more likely in relationships that are not 'very close'; for men (but not women) with peers whose norms are more favourable to condom use; and for subjects who had concurrent sex partners in the last 12 months. In conclusion, we found that: (1) the lack of relationship between the peer norms of drug-using women and their condom use suggests they may have little control over condom use in their relationships--programmes should attempt to empower young women drug users and to develop ways for their peers to influence the men in their lives; (2) epidemiologically, the positive association of concurrency to consistent condom use suggests that condom use may be restricting HIV spread through the community--the presence of consistent condom use in all of the commercial sexual relationships also may restrict HIV spread; (3) prevention efforts should attempt to change peer cultures as a way to develop self-sustaining risk reduction. These changes should include changes in gender roles and power relations. [ABSTRACT FROM AUTHOR] more...

This study was set up to determine the predictors of condom use in the heterosexual non-commercial sexual relationships of young adults who neither inject drugs nor use cocaine, heroin or crack, in a neighbourhood with widespread drug-use-connected HIV. The analytic sample is 279 young adults, aged 18-24, who have never injected drugs and who have not used heroin, cocaine or crack in the last year. They were recruited in the Bushwick neighbourhood of New York City, July 1997 to September 1999. A face-to-face interview included items about their sociodemographic background, substance use and sexual networks. Sexual relationship and self-reported consistent (100%) condom use over the prior year with the partner in a given relationship was examined. Subjects had 337 heterosexual non-commercial relationships. Consistent condom use was reported in 32% of these relationships. In multiple logistic regression, consistent condom use was more likely in relationships that are not 'very close' (odds ratio = 3.92; 95% confidence interval = 2.08, 7.52); in the relationships of subjects whose peer norms support condom use (OR = 1.94; 95% CI = 1.43, 2.69), who are not problem drinkers (OR = 8.70; 95% CI = 2.22, 58.8), and (perhaps as a result of measurement issues) who are men (OR = 1.95; 95% CI = 1.04, 3.68). In conclusion, consistent condom use remains uncommon among youth in this high-risk neighbourhood. It is thus important to keep HIV from entering the sexual networks of youth in communities like this through programmes aimed at drug injectors and their sexual partners. Programmes to increase condom use among young adults should focus on strengthening norms that promote safer sex to protect oneself and others. In addition, assistance should be provided to youth who are problem drinkers. [ABSTRACT FROM AUTHOR] more...
