MSM人群梅毒高危行为同伴群干预研究

目的：综合分析男男性行为（MSM）人群梅毒（Syphilis）高危行为同伴群干预研究。方法招募2011年12月至2014年12月有过肛交或者口交（MSM）人群资料131名，并且在MSM人群知晓的情况下参与调查实验，建立同伴群干预队列。采用SPSS15.0统计学软件进行统计学分析MSM人群的资料以及干预前、干预3.5个月后的MSM同伴群的梅毒高危行为。结果干预前对艾滋病知识的知晓率为36.88%，干预后对艾滋病知识的知晓率为85.98%，干预后131名MSM对艾滋病知识的知晓率显著提高，差异有统计学意义（P<0.05）；干预前梅毒感染率为12.1%，干预后梅毒感染率为9.14%，差异有统计学意义（P<0.05）；干预前最近1次与男性固定性伴侣发生肛交或者口交的安全套使用率为46.54%，干预后最近1次与男性固定性伴侣发生肛交或者口交的安全套使用率为82.67%，差异有统计学意义（P<0.05）。结论由核心人物发起与同伴趋动相结合的方法能够显著降低梅毒感染率，减少MSM人群无保护肛交或者口交行为。
