title: Sexual dysfunction and unprotected anal intercourse among men who have sex with men in two Chinese cities.
abstract: This study investigated the associations between sexual dysfunction and unprotected anal intercourse among adult Chinese men who have sex with men; 519 participants who had had anal sex (past 12 months) were recruited from gay venues (Hong Kong and Shenzhen) and from the Internet (Hong Kong). Respectively, 48.9% and 59.6% (p< .05) of the Hong Kong and Shenzhen participants had had at least one type of sexual dysfunction for 3 consecutive months (past 12 months); the difference may be explained by differential income levels or other factors. After adjustment for significant background variables, three variables related to sexual dysfunction (premature ejaculation, erectile dysfunction, and experienced at least one sexual dysfunction) were significantly associated with unprotected anal intercourse in the Hong Kong (adjusted odds ratio = 1.65-2.80) and Shenzhen samples (adjusted odds ratio = 5.46-6.41). Anxiety about sex was significant only in the Shenzhen sample (adjusted odds ratio = 8.67). The associations may be results of coping toward sexual dysfunction. Sexual dysfunction is prevalent and may contribute to unprotected anal intercourse among men who have sex with men in China. Physiological damages of receptive anal sex may contribute to some types of sexual dysfunction. However, one limitation is that participants were not asked about insertion/receptive anal sex. HIV interventions targeting men who have sex with men in China need to take counseling related to sexual dysfunction into account.
