摘　　要：目的探讨中国男男性接触者(MSM)中异性爱者与素质性同性爱者(gay)艾滋病高危性行为状况。方法采用定向抽样方法,对9城市2250例MSM进行匿名问卷调查,比较其中异性爱组与gay组的高危性行为。结果异性爱组累计同性性伴数(平均13.8个)、近6个月同性性伴数(平均3.8个)、累计同性口交性伴数(平均10.5个)和同性肛交性伴数(平均12.4个),均低于gay组;在婚异性爱组累计女性性伴数(平均4.9个)、近6个月女性性伴数(平均1.7个),均高于在婚gay组。异性爱组同性性交安全套使用率(68.8%)低于gay组;但最近1次同性肛交安全套使用率(91.3%)、与女性性交安全套使用率(63.7%)均高于gay组;两组最近1次同性肛交安全套使用率(分别为91.3%、71.0%)均高于最近1次同性口交安全套使用率。异性爱组最近1年曾参加群交百分率(9.9%)、性交时自己或对方出血过百分率(16.7%)、到外地并与当地男性性交百分率(11.4%),曾向同性买性百分率(4.6%)、16岁前遭遇过成年男性实施的强迫性交百分率(4.2%),均低于gay组。结论MSM中异性爱者与gay的高危性行为存在诸多差异,为有效阻断HIV传播,干预工作应选择重点亚人群进行。Objective To study the risk sexual behaviors related to AIDS between heterosexual and homosexual men who have had sex with men. Methods Target sampling, anonymous questionnaires were adopted to compare sexual behaviors between the two groups, Results The total amount of sex partners with same-sex was 13.8 on average among heterosexual men including 3,8 with male partners in the past 6 months, Numbers of male partners who had oral sex with was 10.5 and anal sex was 12.4 which were both less than with same sex, Among heterosexual men, the total number of female partners was 4.9 on average but number of female partners in the past 6 months was 1.7 which were both more than that among the homosexuals who were all in marriage status. The rate of condom use was 68.8 % （lower than that among homosexual men）, among heterosexual men when having sex with men. The rate of condom use among heterosexual men during last anal intercourse was 91.3 % with male partners or 63.7 % with females. Both figures were higher than that among the homosexuals. The rates of condom use among the two groups were 91.3% and 71.0% respectively during the last anal intercourse with men which were higher than the corresponding rate of condom use during the last oral sex. The rate of heterosexual men who ever had engaged in group sex was 9,9% in the previous year and the incidence of bleeding was 16.7% during sexual intercourse. 11.4 % of them reported ever having had sex with partners from other areas in the last year and 4.2 % had experienced same-sex harassment before 16 years of age. 4.6 % had paid for male-male sex. All these figures were lower than that of the homosexuals. Conclusion The characteristics of high risk sexual behaviors related to AIDS showed much difference in the two groups which called for attention among these groups of MSM.
