目的了解广西贺州市中老年嫖客人群艾滋病（AIDS）相关知识、行为及艾滋病病毒（HIV）感染状况,为广西制定防治策略提供科学参考依据。方法 2013年4-8月,在广西贺州市采用方便抽样调查方法,在卖淫场所、羁押场所和自愿咨询检测门诊,对中老年嫖客进行问卷调查,并采集血样检测HIV、梅毒、丙型肝炎病毒（HCV）抗体,艾滋病相关知识和行为信息用SPSS 17.0统计软件进行分析。结果共调查800名年龄在40岁以上的嫖客,艾滋病知识知晓率为60.25%,最近1年商业性行为坚持使用安全套率为20.57%,HIV抗体检测阳性率1.63%（13/800）,梅毒抗体阳性率10.75%（86/800）,HCV抗体阳性率5.25%（42/800）。多因素Logistic回归分析显示,年龄大[比值比（OR）=11.863,95%可信区间（CI）：5.598~25.142]是嫖客人群艾滋病知识知晓的危险因素,在婚同居（OR=0.517,95%CI：0.328~0.813）和文化水平高（OR=0.062,95%CI：0.007~0.565）是嫖客人群艾滋病知识知晓的保护因素;离异或丧偶（OR=5.440,95%CI：2.371~12.481）是嫖客人群最近l年商业性行为坚持使用安全套的危险因素,中高档次性交易场所（OR=0.203,95%CI：0.113~0.365）、知晓艾滋病知识（OR=0.460,95%CI：0.266~3.796）是嫖客人群最近l年商业性行为坚持使用安全套的保护因素。结论广西贺州市嫖客人群艾滋病知识知晓率低,高危性行为比例高,需要采取针对性的干预措施,进一步遏制艾滋病通过性途径传播蔓延。

Objective To understand the status of AIDS related knowledge, behaviors and HIV prevalence a- mong mid-aged and elderly whoremasters in Hezhou, and provide scientific references for the AIDS prevention and control strategies. Methods By convenient sampling survey method, a questionnaire survey of mid-aged and elderly whoremasters was conducted in prostitution places and detention places. Blood samples were collected to detect HIV, syphilis and HCV antibodies. AIDS related knowledge and behavior were analyzed using SPSS 17 statistical software. Results A total of 800 whoremasters aged 40 and above were surveyed. The awareness rate of AIDS was 60. 250//00. The rate of persistent condom use during commercial sex activities was 20.75% in the past year. The pos- itive rate of HIV, syphilis and HCV antibody was 1. 63% （13/800） , 10.75% （86/800） and 5. 25% （42/800） , respectively. Multivariate Logistic regression analysis showed that old age （OR=11. 863,95% CI： 5. 598--25. 142） was a risk factor of AIDS related knowledge, but married or cohabitated （OR= 0. 517,95 % CI：0. 328-0. 813） and cultural level high （OR=0. 062,95 % CI：0. 007--0. 565） were protective factors of AIDS related knowledge. Divor- ced or widowed （OR= 5. 440,95 %CI：2. 371-12. 481） were risk factors of persistent condom use in commercial sex in the past year, but middle and high grade whoring places （OR=0. 203,95%CI：0. 113--0. 365） and AIDS knowl- edge mastering （OR= 0. 460,95 %CI：0. 266--3. 796） were protective factors of persistent condom use in commercial sex in the past year. Conclusions Commercial sex clients had a low awareness rate of AIDS and high-risk sexual be- haviors. Specific intervention measurements are needed to prevent the spread of AIDS through sexual transmission.
