目的 了解暗娼人群性传播疾病（STD）/艾滋病（AIDS）防治知识水平、行为特征和STD/AIDS感染状况， 为在该人群中开展针对性的干预工作提供依据。 方法 在知情同意后对杭州市区257名暗娼进行面对面问卷调查，对267名暗娼采集血样进行艾滋病病毒（HIV）抗体、梅毒抗体、乙型病毒性肝炎（乙肝）表面抗原（HBsAg）、丙型病毒性肝炎（丙肝）病毒（HCV）抗体检测。所有资料经Epi Data 2.0软件录入，用SPSS 10.0软件进行统计分析。 结果 257名暗娼以未婚低龄为主，20～30岁占86.4%，文化程度普遍偏低。仅13.2%的暗娼完全知晓艾滋病传播途径和预防方法；在最近1周平均接待10位客人，仅25.8%的暗娼在最近1个月每次与客人发生性行为均使用了安全套，36.1%的暗娼自述在最近1年出现过性病相关症状，且其中79.3%自己买药治疗。267名接受采血的暗娼中未发现HIV抗体阳性者，梅毒抗体阳性率为2.6%，HBsAg阳性率为5.6%，丙肝抗体阳性率为0.8%。 结论 针对暗娼人群加强宣传教育、推广安全套使用以及规范性病诊疗转介服务是预防和控制性病/艾滋病在这一人群中流行和蔓延的重要措施。
Objective The study was conducted to investigate the AIDS related knowledge among middle school students and to provide evidence for the development of effective health education on AIDS and sexual activity. Methods An anonymous questionnaire based survey was performed in a cluster randomized sample of students from four grades of eight secondary schools in Lucheng District in April, 2007. Results A total of 465 middle school students were surveyed, the overall awareness rate of AIDS being 74.93%. The rate in men (71.61%) was lower than that in women (78.32%, P0.01). The correctness rate was higher among senior students than junior ones (P0.01). Students of higher grades showed higher awareness rates of HIV/AIDS transmission route, which were significantly higher than those of non transmission routes (P0.01). 1.72% of the students had sexual activities, and 6.25% of them had one partner while 12.50% of them had two. 12.50% of them did not use condoms in the last sexual intercourse; 12.50% of them had made or got pregnant. Conclusion The awareness of AIDS among middle school students suggests insufficient knowledge of AIDS, in particular, misunderstanding in sexual knowledge, in this group. Therefore, further health education on the prevention and control of AIDS, especially the non transmission routes of AIDS and sexual behaviors, should be strengthened.
