To update (1992-2004, Switzerland) trends in behaviors and opinions relative to HIV prevention among men who have sex with men.


A cross sectional survey, repeated five times since 1992, among readers of the gay press and members of gay associations.


An increase was observed in the median number of partners (1994: 5; 2004: 7, p < 0.05), in the proportion of participants who practiced anal penetration with their stable partner (1992: 71%; 2004: 80%, p < 0.05) or with casual partners (1994: 59% 2004: 73%; p < 0.05). Non systematic use of condoms with casual partners during anal penetration increased between 1994 and 2004 (9% to 20%; p < 0.05). Combination therapies gave rise to growing pessimism among participants regarding the decrease in preventive behaviors among homosexuals.


The slow trend towards a reduction of safer sex practices continues among men who have sex with men. It is necessary to strengthen prevention interventions in this population.
