OBJECTIVES: To study the prevalence of human immunodeficiency virus type-1 (HIV-1) and other sexually transmitted infections (STIs) among miners and female sex workers (FSWs) in the tin mining areas of Gejiu City in Yunnan Province, located in southwest China. To assess risk factors for acquiring HIV in these populations.
METHODS: A cross-sectional study was conducted among miners and FSWs in two townships with tin mining by direct-structured interviews and laboratory testing for HIV/STIs.
RESULTS: 1,798 miners and 96 FSWs were enrolled in the study. HIV prevalence based on plasma positivity for antibodies against HIV (anti-HIV) was 8.3% in FSWs and 0.7% in miners. HIV prevalence in FSWs was significantly associated with illegal drug use (odds ratio, OR, 62.24). In addition to illegal drug use (adjusted OR 17.81), HIV prevalence in miners was also significantly associated with the frequency of purchasing sex in the past 12 month (adjusted OR 8.68), tattoo history (adjusted OR 6.55), a history of surgical operation (adjusted OR 6.00) and a history of sharing toothbrush with others (adjusted OR 5.64). In FSWs, STIs prevalence was 12.5% for syphilis, 46.3% for Chlamydia trachomatis, 36.8% for Neisseria gonorrhoeae, 70.8% for HSV-2 and 22.1% for trichomonas vaginalis. In miners, STIs prevalence was 1.8% for syphilis, 4.8% for Chlamydia trachomatis, 0.8% for Neisseria gonorrhoeae and 9.6% for HSV-2. 11.5% of FSWs self-reported the use of illegal drugs.
CONCLUSIONS: The prevalence of HIV and other STIs in the mining areas in Gejiu of Yunnan is high, especially in FSWs. While HIV/STIs prevalence among miners is still relatively low, high-risk sexual behaviors and illegal drug use were reportedly frequent. Therefore, programs focusing on HIV/STIs prevention targeting high-risk groups can be extremely important in communities like Geiju City with high rates of HIV transmission and sizeable floating populations migrating from rural areas for work opportunities.
