目的了解2005-2008年嫖客艾滋病知识、行为特征及其艾滋病病毒(HIV)抗体阳性率、梅毒血清学试验(RPR)阳性率的变化趋势,为指导在嫖客人群中开展防治艾滋病行为干预提供依据。方法每年4-6月和10-12月,对新入收教所的嫖客进行普查,采用统一的男性监测调查表对调查对象进行流行病学调查。结果 2005-2008年共调查2888名嫖客,其文化程度有逐年增高趋势(χ2=146.907,P<0.05);其艾滋病传播途径的知晓率有逐年上升趋势(χ2=44.296,P<0.05),但AIDS非传播途径的知晓率低于传播途径的知晓率;最近一次与小姐发生性行为不使用安全套的比例有逐年上升的趋势(χ2=20.969,P<0.05);最近一个月与小姐发生性行为每次都使用安全套的比例呈现出逐年下降的趋势(χ2=60.455,P<0.05);最近一次与固定性伴发生性行为使用安全套的比例有逐年下降的趋势(χ2=59.795,P<0.05)。结论嫖客中HIV处于低流行水平,但嫖客感染HIV的风险有逐年上升趋势,应加强对嫖客的监测和危险行为干预,提高其安全套使用率。
Objective To understand the changes of AIDS knowledge, behavioral characteristics and HIV antibody positive rate and the positive rate of syphilis serological test (RPR) between 2005 and 2008 in order to provide basis for guiding HIV / AIDS prevention and treatment among clients. Methods From April to June and from October to December each year, the clients of newly admitted teachers were surveyed, and a uniform male monitoring questionnaire was used to conduct epidemiological investigation on the surveyed subjects. Results A total of 2,888 clients were surveyed during 2005-2008, with a gradual increase in their educational level (χ2 = 146.907, P <0.05). The awareness rate of AIDS transmission increased year by year (χ2 = 44.296, P <0.05) The awareness rate of non-AIDS transmission route is lower than the awareness rate of transmission route. The recent rate of non-use of condom in sex with lady tends to increase year by year (χ2 = 20.969, P <0.05) The ratio of condom use on each occasion showed a trend of declining year by year (χ2 = 60.455, P <0.05); the proportion of condom used on sexual intercourse with fixed sex had a trend of declining year by year (χ2 = 59.795, P <0.05) . Conclusion The prevalence of HIV among clients is low, but the risk of HIV infection among clients is increasing year by year. Surveillance of clients and risk behavior intervention should be strengthened to increase their condom use rate.
