摘要:
目的 了解湖北省某市中老年男性HIV感染状况,并分析HIV感染与暗娼的关系,为制定干预措施提供依据.方法 采用分层整群抽样的方法,在该市城郊区和远离城区的街道/乡镇共抽取10个社区/村.采用自行设计的问卷,于2014年12月对抽取社区/村中634名≥50岁男性进行现场调查.结果 该市中老年男性艾滋病相关知识知晓率为13.3%(68/513),63.2%(371/587)认为自己不可能感染艾滋病,9.1%(52/573)可以接受婚外性行为,32.4%(189/583)对“付钱找小姐”表示赞同或无所谓.近半年有过性行为的人中,6.6%(15/228)报告与妻子或同居女友外的人有过性行为,其中63.6%(7/11)报告从未使用安全套,21.8%(128/586)表示身边有熟人朋友付钱找小姐.7例HIV阳性(1.2%,7/601),距离暗娼密集点近的3个调查点HIV阳性检出率分别为4.2%(5/119)、1.1%(1/95)和0.5%(1/192),而距离较远的2个乡镇未检出HIV阳性.13.2%(77/581)报告遇到过暗娼上门提供性服务,其HIV阳性检出率为5.2% (4/77),高于没有遇到过者[0.6%(3/504)](P=0.007).结论 该市中老年男性对艾滋病防治知识知晓率低,感染风险认知低,具有一定的高危性行为,该人群HIV阳性检出率较高,且HIV感染可能与其和暗娼发生性交易有关.%Objective To understand the HIV infection status in middle aged and old men and the association between HIV infection and female sex workers in a city in Hubei province and provide evidence for the targeted prevention and control of HIV infection.Methods Ten communities/villages were selected through stratified cluster sampling from the suburban and rural areas of the city.A total of 634 men aged ≥50 years were surveyed by using self-designed questionnaire in December,2014.Results The awareness rate of HIV/AIDS related knowledge was 13.3% (68/513).Among the men surveyed,63.2% (371/587) thought they couldn't be infected with HIV,9.1% (52/573) believed that extramarital sex is acceptable,and 32.4% (189/583) considered that commercial sexual behavior is just as well.Among the surveyed men reporting sexual behavior in the past 6 months,6.6% (15/228) had sex with regular sexual partners,in which 63.6% (7/11) never used condoms,21.8%(128/586) reported that some friends had commercial sexual behaviors.Among 601 men receiving HIV testing,7 were HIV positive (1.2%).The HIV detection rates among the men living at 3 communities near red light district were 4.2% (5/119),1.1% (1/95) and 0.5% (1/192) respectively;while no HIV infections were found in the men living at 2 towns far away from red light district.Seventy seven of 581 men surveyed (13.2%) reported to meet visiting female sex workers and they had higher HIV positive rate (5.2%,4/77) than those without such experiences (0.6%,3/504) (P=0.007).Conclusion The middle aged and old men in this city had low awareness of HIV/AIDs related knowledge,and high-risk sexual behaviors existed among them.HIV positive rate was relatively high in this population,and HIV infection might be associated with sex service.
