Results: Of the MSM, four-fifths had engaged in oral-genital intercourse, about half had engaged in anal intercourse, and in the past year more than two-fifths had casual sexual partner(s).Very few maintained monogamous sexual relationships, and nearly half also had intercourse with women. One fourth had previously been diagnosed with a venereal diseases. One HIV+individual was found among the 40 who reported having been tested for HIV. Only two men consistently used condoms among the one-third who had ever used condoms, despite almost universal knowledge of HIV and its transmission. Conclusions: MSM in China's Mainland are very sexually active, highlighting the possibility of a serious HIV epidemic that may be directly spread to the female population. However,AIDS interventions targeting MSM face severe obstructions resulting from cultural bias and other factors.展开更多

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 behaviors that 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.

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 Chinesegays related to suicide attempts and commitment.

Methods Region-specific population, behavior, serosurveillence, and policy/program data （from 1995 to 2020） were gathered from various local and national organizations and applied to the Asian Epidemic Model （AEM） and used to derive estimates of future HIV prevalence, epidemic trends, and outcomes of intervention strategies. Results The AEM projections for 2020 included increased number of people living with HIV （PLHIV; to 136 617）, increased HIV prevalence （2.51%）, and 8037 deaths from acquired immunodeficiency syndrome （AIDS） in this region. However, the overall HIV incidence rate （per 10 000） was projected to decline from 27 in 2015 to 22 in 2020, largely due to a predicted decrease in HIV infection rate （per 10 000） from 658 in 2013 to 621 in 2020 among intravenous drug users. In contrast, the cases of HIV infection per i0 000 was projected to increase from 420 in 2010 to 503 in 2020 among men who have sex with men, and from 8 in 2010 to 15 in 2020 among the general population. The predominant risk factor for HIV transmission over the next decade in Liangshan was casual sex. Community-based outreach strategies to reduce injected drug use and casual sex, and to promote condom use, were predicted as effective interventions to decrease HIV transmission. Conclusion Implementation of a comprehensive public health program, with targeting to the region-specific at-risk populations, will help to mitigate HIV/AIDS spread in Liangshan.展开更多
