福建省某市不同档次场所女性性工作者艾滋病/性病感染状况调查

Prevalence of HIV and sexually transmitted infections among female sex workers in different work sites of a city in Fujian Province

目的了解福建省某市不同档次场所女性性工作者(FSWs)人类免疫病毒(HIV)、梅毒、淋病、沙眼衣原体、阴道毛滴虫和单纯疱疹病毒2型(HSV-2)的感染情况并比较其行为学特征差异。方法招募FSWs调查其人口学、行为学以及生殖健康状况,采集静脉血进行HIV、HSV-2和梅毒血清学检测,采集宫颈分泌物进行淋球菌和沙眼衣原体检测,采集阴道分泌物进行阴道毛滴虫检测。结果 837例研究对象经知情同意参加调查。HIV、梅毒、淋球菌、沙眼衣原体、阴道毛滴虫、HSV-2感染率分别为2.9%、8.1%、11.5%、28.1%、11.8%和68.1%。低档场所FSWs的HIV、HSV-2感染率(5.5%、74.0%)高于中高档场所FSWs(1.5%、65.0%),差异有统计学意义。低档场所FSWs年龄较高,静脉注射和经口吸毒的比例明显高于中高档场所,最近1周嫖客数多。结论不同档次场所的FSWs有着不同的人口学和行为学特征,以及不同的HIV感染相关因素,需针对不同档次场所FSWs采取针对性的干预措施,控制HIV/性传播疾病(STIs)的传播流行。

Objective To explore the infection prevalence of HIV,syphilis,gonorrhoea,chlamydia trachomatis,vaginal trichomoniasis and herpes simplex virus-II( HSV-2) among female sex workers( FSWs) in different work sites in a city of Fujian Province and to compare the difference of behavioral characteristics. Methods FSWs were recruited to investigate their demographics,behavioral character and reproductive health status. Venous blood were collected to test HIV,HSV-2 and syphilis,cervical secretion were collected to test gonorrhoea and chlamydia trachomatis,and vaginal secretion were collected to test trichomonas vaginalis. Results A total of 837 FSWs were invited to participate in the study after gained informed consent. The prevalence rates of HIV,syphilis,gonorrhoea,chlamydia trachomatis,vaginal trichomoniasis and HSV-2 were 2. 9%,8. 1%,11. 5%,28. 1%,11. 8%,68. 1%, respectively. FSWs at low level work sites had higher prevalence of HIV and HSV-2( 5. 5%,74. 0% vs 1. 5%,65. 0%). Compared with FSWs worked at middle-high level sites,FSWs at low level work sites were elderly,the percentages of injection drug users and non-injection drug users were higher,and they had more clients in last week. Conclusion Demographics,behavioral characters and factors associated with HIV infection are distinguished among FSWs in different levels of sexual work sites. Intervention should be conducted according to FSWs in different levels of sexual work sites so that the epidemics of HIV / sexually transmitted infections( STIs) can be controlled.
