title: Evaluation of AIDS prevention among homosexual and bisexual men in Switzerland.
abstract: Attitudinal and behavioural change among gay men in Switzerland was measured between 1987 and 1990 to evaluate the effectiveness of AIDS prevention activities. The methodology used included a self-administered questionnaire published in Swiss gay magazines and distributed by gay organizations (N = 795 in 1987, N = 720 in 1990) and in-depth interviews with men recruited through advertisements and through the questionnaire (N = 42 in 1987, N = 24 in 1990). The two independent sampling procedures yielded similar samples with regard to socio-demographic characteristics, allowing comparisons to be made between the 1987 and 1990 data. Personal confrontation with AIDS (knowing someone who is HIV-positive, or who is ill or dead from AIDS) increased significantly during the period but more adequate ways of coping developed. Behavioural change towards safer sex began well before the first study. The majority of responding homosexuals have adapted their sexual behaviour to the new situation created by AIDS and generally maintain a protective behaviour. However, "exceptions" (condom rupture or episodes of non-protection) are not infrequent and should deserve more attention. Three indicators of sexual behaviour (number of sexual partners, anal sex and use of condom and oral sex with ejaculation), reported for the last 3 months before each study, exhibit few changes between 1987 and 1990: number of partners remained stable, unprotected oral sex decreased. Anal sex slightly increased, the use of condoms remaining stable. Sixty-seven percent of the sample knew their serostatus in 1990 (57% in 1987), and 13% of these stated that they were HIV+ (14% in 1987).
