目的了解江苏省南通市男男性接触人群(MSM)艾滋病病毒(HIV)感染者阳性告知前后艾滋病防治知识知晓率和行为学特征改变。方法选取2005年1月—2013年9月南通市艾滋病自愿咨询检测(VCT)门诊M SM人群HIV感染者94人,在阳性告知前后进行问卷调查。结果告知后艾滋病知晓率97.85%明显高于告知前84.04%(χ~2=8.847,P<0.01),其中初中及以下文化程度组告知后知晓率95.00%明显高于告知前75.00%(χ~2=4.021,P<0.05)。同性性行为肛交方式有改变(χ~2=14.270,P<0.01);安全套使用率提高(χ~2=154.183,P<0.05),告知后每次使用比例72.73%明显高于告知前5.74%;但告知前后性伴数没有差异。在同性商业性行为中,告知后性伴数减少(χ~2=9.090,P<0.05),安全套使用率提高(χ~2=7.391,P<0.05),告知后每次使用比例71.43%高于告知前11.76%,但肛交类型没有改变。在与异性发生性行为中,安全套使用率提高(χ~2=7.400,P<0.05),告知后每次使用比例86.40%高于告知前42.50%。结论南通地区M SM人群HIV感染者知晓率整体较高,阳性告知后减少了高危行为。
Objective To understand the awareness of AIDS prevention and control knowledge and behavioral changes before and after positive HIV infection in men who have sex with men (MSM) in Nantong City, Jiangsu Province. Methods Ninety-four HIV-infected individuals in M SM population of the AIDS voluntary counseling and testing (VCT) clinic in Nantong from January 2005 to September 2013 were selected and questionnaires were conducted before and after the positive notification. The awareness rate of HIV / AIDS was 97.85%, which was significantly higher than 84.04% (χ ~ 2 = 8.847, P <0.01). The awareness rate of 95.00% in junior high school and below education group was significantly higher than that of 75.00% 2 = 4.021, P <0.05). (Χ ~ 2 = 14.270, P <0.01); condom use rate increased (χ ~ 2 = 154.183, P <0.05), and the ratio of each use 72.73% was significantly higher than that of the former 5.74% ; But there is no difference between the number of sexual partners before and after informing. In same-sex commercial sex, the number of sexual partners decreased (χ ~ 2 = 9.090, P <0.05), condom use rate increased (χ ~ 2 = 7.391, P <0.05), and the ratio of each sexual use was 71.43% Before informing the top 11.76%, but the type of anal sex did not change. Condom use was higher in sex with the opposite sex (χ ~ 2 = 7.400, P <0.05), with 86.40% being higher than 42.50% before giving notice. Conclusion The awareness rate of HIV-infected persons in M SM population in Nantong area is generally high, which reduces the high-risk behaviors after being positive.
