HIV infection and associated factors in HIV-antibody positive clients of female sex workers recently reported in Shaanxi province

Abstract

Objective: 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. Methods: 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. Results: 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 (aOR=0.28, 95% CI: 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 (aOR=3.14, 95% CI: 1.06-9.30) and blood donation test (aOR=4.19, 95% CI: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 (aOR=0.19, 95%CI: 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 (aOR=9.03, 95% CI: 3.00-27.18) (P<0.05). Conclusions: 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.
