目的评价重庆市某区女性性服务工作者(FSW)艾滋病防治行为干预效果。方法采取二阶段整群抽样法确定调查场所和人数,比较行为干预前后艾滋病相关知识知晓率、就医模式、安全性行为、梅毒感染率等差异,综合评价该区FSW人群艾滋病防治行为干预效果。结果行为干预后,FSW人群在艾滋病相关知识知晓率(χ2=23.52,P﹤0.005)、性病就医模式正确率(χ2=4.89,P﹤0.05)方面有显著提高;高档场所FSW人群安全性行为率(χ2=4.89,P﹤0.05)明显提高;低档场所FSW人群安全套使用率(χ2=2.69,P﹥0.1)无明显变化;梅毒感染率无根本变化(χ2=0.84,P﹥0.25)。结论该区FSW人群艾滋病防治行为干预效果显著,但低档场所FSW人群安全性行为率仍然很低,需要加强对低档场所FSW人群的行为干预。
Objective To evaluate the effectiveness of HIV / AIDS prevention and treatment interventions by female sex workers (FSWs) in a district of Chongqing. Methods Two-stage cluster sampling method was used to determine the place and number of people surveyed. The differences of awareness of AIDS-related knowledge, medical treatment patterns, safety behaviors and syphilis infection rates before and after behavioral intervention were compared to evaluate the effect of AIDS prevention and control behavior in FSW population. Results After behavioral intervention, the rate of awareness of AIDS-related knowledge (χ2 = 23.52, P <0.005) and the correct rate of STD medical treatment (χ2 = 4.89, P <0.05) were significantly increased in FSW population. (χ2 = 4.89, P <0.05). There was no significant change in condom use rate in low-grade FSW population (χ2 = 2.69, P> 0.1). There was no significant change in syphilis infection rate (χ2 = 0.84, P> 0.25). Conclusion The prevention and treatment of AIDS among FSW population in this area is significant. However, the safety behavior rate of FSW in low-grade places is still low, and it is necessary to strengthen behavioral intervention in low-grade FSW population.
