目的了解深圳市男男性行为者(MSM)梅毒合并人类免疫缺陷病毒(HIV)感染分布特征及其影响因素。方法对2005—2011年广东省深圳市MSM梅毒/HIV监测资料进行Cochran-Armitage趋势检验和logistic回归分析。结果 5 232例接受自愿咨询检测MSM中梅毒感染率为20.97%,HIV感染率为6.46%,梅毒合并HIV感染率为3.56%;2005—2011年深圳市MSM人群梅毒合并HIV感染率呈上升趋势(Z=-3.735 9,P=0.000 2);多因素logistic回归分析结果显示,MSM年龄≥40岁者梅毒合并HIV感染的危险性是年龄<40岁者的2.165倍(OR=2.165),大专及以上文化程度者梅毒合并HIV感染的危险性是初中及以下者的0.522倍(OR=0.522),性角色以主动为主者和主、被动二者兼有者梅毒合并HIV感染的危险性分别是被动为主者的0.388倍(OR=0.388)和0.606倍(OR=0.606)。结论广东省深圳市MSM人群梅毒合并HIV感染率呈上升趋势,有针对性地开展梅毒/HIV预防控制工作迫在眉睫。
Objective To investigate the distribution and influencing factors of syphilis with human immunodeficiency virus (HIV) infection in MSM in Shenzhen. Methods Cochran-Armitage trend test and logistic regression analysis were performed on MSM syphilis / HIV surveillance data from 2005 to 2011 in Shenzhen, Guangdong Province. Results In 5 232 MSM cases, the prevalence of syphilis infection was 20.97%, the HIV infection rate was 6.46% and the syphilis infection rate was 3.56%. In 2005-2011, the syphilis infection rate among MSM population in Shenzhen increased ( Z = -3.735 9, P = 0.0002). Multivariate logistic regression analysis showed that the risk of syphilis with HIV infection in MSM aged 40 years or older was 2.165 times (OR = 2.165) The risk of syphilis with HIV infection was 0.522 times (OR = 0.522) higher than that of junior high school students or below, and the risk of syphilis with HIV infection was mainly sexual and active and both were passive Passive were 0.388 times (OR = 0.388) and 0.606 times (OR = 0.606). Conclusions There is a rising trend of syphilis with HIV infection among MSM population in Shenzhen City, Guangdong Province. It is imminent to conduct targeted syphilis / HIV prevention and control work.
