Objectives: To probe some more important factors affecting the HIV epidemic by surveying the relationshipbetween AIDS high risk behaviors and childhood status,attitude/perception to gender of male/sex orientation andrare experiences/Psy-chology among Chinese gays. Methods: Data were collected from 240 Chinese gays whowere attracted by their same gender. Results: The extent of sex among China's Mainland gays issimilar to that of industrialized countries, and behaviorsthat exacerbate the HIV epidemic are universal.Perceptions 'being a girl is better',' Dislike toys likeswords or pistols in early childhood were predictors topassive anal intercourse in adulthood. Those gay men whobegan sexual intercourse younger than 16 years old tendedto have more sex partners and suffered more pain. Thosedisliked gender of male or self-regarded as female tended tohave more passive anal intercourse and related to childhoodcross-gender experience/psychology while those were raised as girls by their parentsdid not take on e above characters. Individuals who experienced sex coercion and drug abuse were the twosubgroups with the greatest high-risk behaviors. Individualswho had sex with females had the greatest number of malesex partners and were more prone to group sex. Individualswith pedophilia or gerontophilia had more casual sexpartners. Psychological problems encountered by Chinese Conclusions: The prospect of an extensive AIDSepidemic among Chinese gays does exist and somesubgroups of gays play more important roles in theepidemic. Some high risk behaviors among adult gays canbe foreseen explicitly by the predictors taking on inchildhood, and closely relate to attitude/perception, togender of male, to some rare experience/psychology. 展开更多
