目的了解襄阳市男男性行为人群(MSM)艾滋病防治知识和行为特征以及艾滋病/性病感染状况,为在该人群中开展有针对性的干预工作提供依据。方法对襄阳市MSM人群艾滋病专题调查,资料进行描述性、单因素和多因素Logistic回归分析。结果调查1 201例MSM人群,艾滋病防治知识知晓率为97.92%。最近六个月与同性发生肛交性行为时,每次都用安全套的比例为33.25%,艾滋病病毒感染率3.91%。多因素Logistic分析显示,年龄40岁及以上(OR=1.62,95%CI=1.14~2.74)、与女性已婚或同居(OR=2.34,95%CI=1.16~4.69)是HIV感染的危险因素;最近一年接受过同伴教育(OR=0.50,95%CI=0.26~0.95)、最近一次肛交时使用安全套(OR=0.34,95%CI=0.18~0.65)是保护性因素。结论襄阳市MSM人群HIV感染率较高,影响因素复杂。应对40岁以上、与异性已婚或同居的MSM人群开展以同伴教育为主的综合干预措施,增强其艾滋病防治意识,提高安全套使用率。
Objective To understand the HIV / AIDS prevention and treatment knowledge and behavior characteristics and the status of HIV / AIDS in MSM of Xiangyang and provide the basis for targeted intervention in this population. Methods The survey of HIV / AIDS in MSM population in Xiangyang City was conducted with descriptive, univariate and multivariate Logistic regression analysis. Results A total of 1 201 cases of MSM population were surveyed. The awareness rate of AIDS prevention and treatment was 97.92%. In the last six months, with homosexual anal sex, each time the proportion of condoms was 33.25%, 3.91% of the HIV infection rate. Multivariate logistic analysis showed that those aged 40 and over (OR = 1.62, 95% CI = 1.14-2.74) were significantly associated with female HIV status (OR = 2.34,95% CI = 1.16-4.96) (OR = 0.50, 95% CI = 0.26-0.95). The most recent condom use on anal sex (OR = 0.34, 95% CI = 0.18-0.65) was a protective factor. Conclusion The HIV prevalence in MSM population in Xiangyang is high and the influencing factors are complicated. Coping strategies should be developed for those over the age of 40 who are MSM with heterosexual married or living together to enhance their HIV / AIDS awareness and condom use.
