婚姻状况对男男性行为者的艾滋病高危性行为影响研究

Comparison of AIDS related high risk behaviors between married and unmarried men who have sex with men.

目的探讨中国男男性行为者(MSM)中,在婚与非在婚亚人群艾滋病高危性行为状况。方法采用定向抽样方法,对9个城市2250名MSM进行匿名问卷调查,比较在婚与非在婚亚人群的高危行为。结果在婚组累计同性性伴数、同性口交性伴数、同性肛交性伴数、近1年内向男性"买"性次数,均明显高于非在婚组(P均<0.01);在婚组与男女性交及最近1次与女性性交时安全套使用率、近6个月内"买"性时安全套使用频率,明显低于非在婚组(P<0.05或0.01);在婚组近6个月内在男同性爱者活动场所与陌生男性性交、最近1次与不熟悉或陌生男性性交、曾经向男性"买"性及有过肛交行为的百分率,明显高于非在婚组(P<0.05或0.01);在婚组近6个月女性性伴数、是男性性工作者、最近1次与男性性工作者性交、有固定的男性伴侣、近1年内性交时曾出血、近1年内在外地与男性性交的百分率,明显低于非在婚组(P<0.05或0.01)。结论MSM中,在婚与非在婚亚人群的高危行为存在诸多差异。婚姻不能制约其高危性行为,为有效阻断艾滋病病毒的传播,应对不同的MSM亚人群选择不同的艾滋病干预措施。

Objective To explore AIDS related high risk sexual behaviors between married and unmarried men who have had sex with men（ MSM）and provide relevant interventions for AIDS control and prevention. Methods Target sampling was employed to select 2 250 MSM in 9 cities and,anonymous questionnaires were administered for them to compare high risk behaviors between married and unmarried MSM. Results The accumulative number of homo-sex partners, frequency of oral intercourse with homo-sex partners and frequency of＂buying＂sex from men in the past year in the married group were significantly higher than in the unmarried group（P （0.01）. The rates of condom use in sex intercourse with men or women,in the last intercourse with women and in＂buying＂sex in the last six months among the married group were much lower than those among the unmarried group（P 〈 0.05 or 0.01 ）.The percentages of having sex with unknown men in gay venues during the past 6 months, the last intercourse with unfamiliar or strange men, ＂buying＂sex from men and having anal intercourse with men in the married group were all higher than those in the unmarried group（ P 〈 0.05 or 0.01）. The number of female sex partners in the past 6 months, being mate sex workers, having recent sex with male sex workers and having regular sex partners,as well as episodes of bleeding during sex in the past year and the rate of having sex with men in other cities in the past year in the married group were all higher than those in the unmarried group （P 〈 0.05 or 0.01 ） . Conclusion There are great differences in AIDS related high risk behaviors between the married and unmarried MSM, and marital status is not able to restrict their high risk behaviors. To effectively contain HIV transmission, relevant interventions should be adopted towards different subgroups of MSM population.
