目的对不同层次娱乐场所的女性商业性工作者进行艾滋病干预并对干预效果进行评价和分析,为今后不同娱乐场所采取不同的干预措施提供科学依据。方法采取分层抽样方法,将娱乐场所分为高、中、低档三个层次,以外展服务的方式到这些娱乐场所对女性性工作者开展艾滋病干预活动,同时使其在干预前和干预后的1个月分别填写调查问卷,以便了解其在干预前后的艾滋病防治知识知晓率、使用安全套的态度以及相关行为改变情况,对干预效果进行评价。结果通过对女性性工作者的干预,提高了该人群对艾滋病防治知识的知晓率,促进了其使用安全套的态度和相关行为的转变。该人群艾滋病防治知识总体知晓率由干预前49.4%上升到77.0%(x~2=12.6,P<0.05);最近一次安全套的使用率由干预前的61.7%上升到87.8%(x~2=13.8,P<0.05);最近三次安全套的使用率由干预前的64.5%上升到82.4%(x~2=9.0,P>0.05);以上差异均有统计学意义。结论通过外展服务的方式对娱乐场所的女性性工作者进行高危行为干预,可以有效的提高她们的艾滋病防治知识和安全套的使用率,但娱乐场所档次不同干预效果也不同。
Objective To evaluate the HIV/AIDS intervention among female commercial sex workers at different levels of entertainment venues and to evaluate and analyze the effects of interventions, so as to provide scientific evidence for different interventions to be taken in different entertainment venues in the future. Methods A stratified sampling method was adopted to divide the entertainment venues into three levels: high, medium and low-end, and to provide HIV services to female sex workers at these entertainment venues. At the same time, it was used before and after intervention. One month each questionnaire was filled out to understand the awareness of HIV/AIDS prevention and treatment before and after intervention, the attitude of using condoms, and the related behavior changes, and evaluate the effectiveness of the intervention. Results Through the intervention of female sex workers, the awareness of the population about AIDS prevention and control knowledge was improved, and the attitude of using condoms and the change of related behaviors were promoted. The overall awareness rate of AIDS prevention knowledge in the population increased from 49.4% to 77.0% (x~2=12.6, P<0.05), and the rate of use of the last condom increased from 61.7% to 87.8% (x~2= 13.8, P<0.05); The use of condoms in the last three sessions increased from 64.5% before intervention to 82.4% (x~2=9.0, P>0.05); the above differences were statistically significant. Conclusion High-risk behavioral interventions for female sex workers in entertainment venues through outreaching services can effectively improve their HIV/AIDS prevention knowledge and condom use rates, but the effect of different interventions on the level of entertainment venues is also different.
