To investigate the current status of HIV infection and the related factors in HIV antibody positive clients of female sex workers (FSWs) recently reported in Shaanxi province. The HIV/AIDS cases newly diagnosed in males living in Shaanxi from January 1th of 2013 to June 30th of 2014 were selected and those infected through " commercial heterosexual behavior" were identified. The information about their demographic characteristics, previous unprotected heterosexual sex and the sample sources were collected, and serum or plasma samples were collected from them and tested with BED-CEIA. The proportion of recent HIV infections and associated factors were investigated. The proportion of recent HIV infection and HIV-antibody detection rate in 212 HIV antibody positive male clients of FSWs were 25.5% and 6.6% respectively. The cases who had the educational level of junior middle school or high middle school were wore likely to have long term HIV infections than those with lower educational level (a=0.28, 95: 0.08-0.93). Compared with patients identified by hospitals or sexually transmitted diseases clinics, recent HIV infections were more likely to be found through preoperative test or blood transfusion test (a=3.14, 95: 1.06-9.30) and blood donation test (a=4.19, 95:1.01-17.42). Compared with the cases who had commercial sex only in Xi' an or other province or both in Xi' an and other province, the cases who had commercial sex in other cities in Shaanxi were more likely to be infected recently (a=0.19, 95: 0.07-0.57). Compared with the cases had temporary heterosexual sex partner, those who had no temporary sex partners were more likely to be infected recently (a=9.03, 95: 3.00-27.18) (<0.05). The proportion of recent HIV infections among HIV antibody positive clients of FSWs was high and the HIV-antibody detection rate among them was low. The educational level, sample source, geographic area and temporary heterosexual partner were related factors for recent HIV infection. The HIV infection in the clients of FSWs, especially those with lower educational level, was serious in Shaanxi. It is necessary to strengthen behavior intervention and improve HIV defection according to the characteristics of this population.
为了解陕西省近期报告的女性性工作者（FSW）HIV抗体阳性者的HIV感染现状及相关因素。选取2013年1月1日至2014年6月30日在陕西省新诊断的男性HIV/AIDS病例，确定其中经“商业异性性行为”感染的病例。收集其人口学特征、既往无保护异性性行为及样本来源等信息，并采集血清或血浆样本，采用BED-CEIA进行检测。调查近期HIV感染比例及相关因素。212例FSW的男性HIV抗体阳性者中近期HIV感染比例和HIV抗体检测率分别为25.5%和6.6%。初中或高中学历者较学历更低者更易发生长期HIV感染（α=0.28，95%CI：0.08 - 0.93）。与经医院或性病门诊确诊的患者相比，近期HIV感染更易通过术前检测或输血检测发现（α=3.14，95%CI：1.06 - 9.30）以及献血检测发现（α=4.19，95%CI：1.01 - 17.42）。与仅在西安或其他省份或在西安和其他省份均有商业性行为的病例相比，在陕西省其他城市有商业性行为的病例近期更易感染（α=0.19，95%CI：0.07 - 0.57）。与有临时异性性伴侣的病例相比，无临时性伴侣者近期更易感染（α=9.03，95%CI：3.00 - 27.18）（P<0.05）。FSW的HIV抗体阳性者中近期HIV感染比例较高，而HIV抗体检测率较低。学历、样本来源、地域及临时异性性伴侣是近期HIV感染的相关因素。陕西省FSW的HIV感染情况严重，尤其是学历较低者。有必要根据该人群特点加强行为干预并提高HIV检测率。
