目的了解娱乐场所女性服务人员(FEWs)艾滋病病毒(HIV)、梅毒螺旋体(TP)感染状况及其相关行为学动态变化特征,为进一步完善监测、干预措施及策略的制定提供参考。方法按云南省哨点监测方案,每年在固定时间、固定地点采用重复横断面调查方法收集人口学及相关行为学资料并采集血液标本,对血清学标本进行HIV、TP检测。结果 2005-2012年,共开展FEWs行为学监测7563人份,血清学监测7512人份。其中,艾滋病知识知晓率由2005年92.58%、2006年78.89%上升到2012年99.76%;最近一次安全套使用率均在95%以上,最近1个月每次安全套使用率由2005年的81.34%上升到2012年的94.83%;HIV抗体阳性检出率0.48%(1.55%～0.24%),呈下降趋势(χ2趋势=4.83,P<0.05);TP抗体阳性检出率1.85%(4.13%～1.18%),呈逐年下降趋势(χ2趋势=25.86,P<0.01);HIV、梅毒阳性检出率与最近1个月每次均用安全套率呈负相关(HIV:OR=0.932,95%CI:0.893～0.973;梅毒:OR=0.488,95%CI:0.431～0.552,P<0.05),与知识知晓率、最近一次用安全套率、吸毒者比例均未呈现一定的相互关系(P均>0.05)。结论玉溪市娱乐场所女性服务人员HIV流行仍处于较低水平,健康教育、推广使用安全套取得一定效果。
Objective To understand the characteristics of HIV and TP infections among female service workers (FEWs) in entertainment venues and their related behavioral changes, and provide references for further improvement of surveillance, interventions and strategies. Methods According to the sentinel surveillance program in Yunnan Province, repeated cross-sectional surveys were conducted at fixed times and fixed locations to collect demographic and behavioral data and to collect blood samples. Serological samples were tested for HIV and TP. Results From 2005 to 2012, a total of 7563 FEWs behavioral surveys and 7512 serological tests were conducted. Among them, the AIDS awareness rate increased from 92.58% in 2005 and 78.89% in 2006 to 99.76% in 2012; the most recent condom use rate was above 95%; the condom use rate in each of the last month increased from 81.34% in 2005 To 94.83% in 2012; the positive rate of HIV antibody was 0.48% (1.55% -0.24%), showing a decreasing trend (χ2 trend = 4.83, P <0.05); the positive rate of TP antibody was 1.85% (4.13% -1.18 (HIV: OR = 0.932, 95% CI: 1). The positive rates of HIV and syphilis were negatively correlated with the rate of condom use in each of the most recent 1 month (χ2 trend = 25.86, 0.893-0.973; syphilis: OR = 0.488, 95% CI: 0.431-0.552, P <0.05), but no correlation was found with knowledge awareness rate, recent condom use rate and the proportion of drug users (all P> 0.05) . Conclusions HIV prevalence of female service staff in entertainment places in Yuxi City is still at a low level. Health education and promotion of condom use have achieved some results.
