Popis: To determine factors associated with likelihood or failure to use condoms with primary sexual partners among injecting drug users (IDU) in two cities.Interviews were conducted with 601 IDU in Bangkok in 1989 and with 957 IDU in New York City in 1990-1991. Subjects were recruited from drug-use treatment programs and a research storefront. Informed consent was obtained and a World Health Organization standardized questionnaire about AIDS risk behaviors administered by a trained interviewer.A substantial minority (37%) of IDU in Bangkok and a majority (55%) of IDU in New York City reported penetrative intercourse (vaginal, anal or oral) with a primary partner in the 6 months before the interview. Of those reporting penetrative intercourse with a primary partner, only 12% in Bangkok and 20% in New York reported that they always used condoms. Parallel bivariate and multiple logistic regression analyses were conducted to distinguish between subjects who reported always using condoms and subjects who reported unsafe sexual activity with primary partners. The same two factor--knowing that one is HIV-seropositive and talking about AIDS with sexual partners--were most strongly associated with always using condoms with primary partners in both cities.Programs to prevent sexual transmission of HIV among IDU should provide voluntary and confidential/anonymous HIV counseling and testing, and should facilitate discussions of AIDS and sexual transmission of HIV between IDU and their sexual partners. That the same two factors were associated with always using condoms with primary partners among IDU in these two cities suggests that these factors may also be important in other groups at high risk for HIV.Trained interviewers spoke to 957 drug users attending a detoxification program, methadone maintenance program, or a research storefront in New York City in 1990-91 and to 601 drug users attending 17 drug use treatment clinics in Bangkok, Thailand, in the autumn of 1989 as part of a study to identify factors linked to the probability or failure of condom use with primary sexual partners among IV drug users. The participants also received HIV counseling and testing. IV drug users in New York City were more likely to be older (36.2 years vs. 30.1 years; p .001), female (25% vs. 5%; p .001), more ethnically diverse (p .001), and inject cocaine more often (33 injections/month vs. 0.5 injections/month) than those in Bangkok. 44% of drug users in New York City and 33% of those in Bangkok engaged in some unprotected penetrative intercourse with a primary heterosexual partner in the previous 6 months. Of drug users having penetrative sexual intercourse with a primary partner in the previous 6 months, 20% in New York City and 12% in Bangkok always used condoms (p .02). The strongest predictors of condom use among IV drug users from both countries were a previous positive HIV test and talking about AIDS with sexual partners (p = .001 for US; p = .0008 for Bangkok and p = .004 for US; p = .0596 for Bangkok, respectively). These findings indicated that unsafe sexual behavior with primary sexual partners among drug users is still a major source of HIV transmission in these 2 cities. Nevertheless, knowledge of HIV positive status and partner communication concerning AIDS are predictors of condom use shared by both groups. Thus, HIV/AIDS prevention programs should provide confidential HIV testing and counseling for drug users and should encourage frank discussions of AIDS between drug users and primary sexual partners. Peer support for risk reduction among drug users has the potential to facilitate such discussions.
