目的了解实施世界银行卫生Ⅸ项目地区和非项目地区,暗娼人群性病患病率及性病知识知晓率,评估项目地区干预的效果。方法采用面对面问卷调查,同时对高、中、低挡娱乐场所的暗娼,进行皮肤、生殖器部位和有关的妇科检查;采血检测艾滋病病毒和梅毒抗体;采集宫颈分泌物做淋球菌培养及沙眼衣原体抗原检测。结果暗娼性病预防知识的知晓率总体为38.7%,项目地区为51.2%,非项目地区26.1%(P=0.000)。最近一次性行为中安全套的使用率,项目地区为68.1%,非项目地区59.8%(P>0.05)。不同档次的场所中,项目地区暗娼的的安全套使用率较非项目地区高(P<0.01)。正确就医率:项目地区为96.3%,高于非项目地区的92.5%(P>0.05)。性病患病率:总患病率为14.55%;尖锐湿疣1.46%,生殖器疱疹0.21%,生殖器溃疡2.08%,梅毒3.53%,沙眼衣原体6.03%,淋病4.99%。其中有1.66%合并两种性病感染。性病患病率项目地区低于非项目地区(P<0.05)。不同挡次场所暗娼性病患病率,非项目地区比项目地区高。非项目地区低档场所暗娼性病患病率高达28.3%。255例临床体检阴性者,经实验室检出性病感染者31例(12.2%),其中项目地区12例(10.8%),非项目地区19例(13.2%)。结论非项目地区暗娼人群各项评估指标结果都高于项目地区,表明项目地区在性病艾滋病的干预工作中取得了显著成效。
Objective To understand the prevalence rate of STD and sexually transmitted diseases (STD) among the female sex workers in the regions and non-project areas of the World Health IX in the World Bank and evaluate the effect of regional interventions. Methods The face-to-face questionnaire was used to investigate the genital area of gynecology and gynecological examination of the sex workers in high, medium and low-noise entertainment venues. Blood samples were collected for the detection of HIV and syphilis antibodies. The cervical secretions were collected for gonococcal culture and Chlamydia trachomatis antigen Detection. Results The awareness rate of STD prevention among commercial sex workers was 38.7% in total, 51.2% in the project area and 26.1% in the non-project area (P = 0.000). The rate of condom use in the most recent one-time sexual activity was 68.1% in the project area and 59.8% in the non-project area (P> 0.05). In different places, the use rate of condom in commercial sex workers in the project area was higher than that in non-project areas (P <0.01). Proper medical coverage: The project area was 96.3%, higher than non-project area 92.5% (P> 0.05). The prevalence of STDs was 14.55%. Genital warts 1.46%, Genital herpes 0.21%, Genital ulcer 2.08%, Syphilis 3.53%, Chlamydia trachomatis 6.03% and Gonorrhea 4.99%. 1.66% of them combined with two STD infections. The prevalence of STDs in the project areas was lower than that in non-project areas (P <0.05). The prevalence rates of STDs in different places were higher in non-project areas than in the project areas. The prevalence of venereal diseases in non-project places was 28.3%. Among 255 cases with negative clinical examination, 31 (12.2%) were STD-infected in the laboratory, including 12 cases (10.8%) in project area and 19 cases (13.2%) in non-project area. Conclusion The results of all the evaluation indicators of FSW among non-project areas are higher than that of the project areas, indicating that the project areas have achieved remarkable results in the intervention of STD and AIDS.
