Objective To estimate human immunodeficiency virus (HIV)/sexually transmitted diseases(STDs) related knowledge, the prevalence and risk factors for HIV/STDs among tin miners in Gejiu, Yunnan Province. Methods A cross-sectional study was conducted in tin miners working at 5 mining regions from March to June"2006 in Gejiu City, Yunnan Province. A total of 1796 miners were enrolled in the study, and a standardized questionnaire was administered probing socio-demographic factors, knowledge of HIV/STDs and sexual behavior. 7ml-volume venous blood and l5ml urine specimens were collected for HIV/STDs testing. Results Twelve participants [0.7% 12/1760) were identified HIV positive. While, the positive proportions for syphilis, herpes simplex virus type-2 (HSV-2), Neisseria gonorrhea and Chlamydia trachoma were 1.8% (31/1760), 9.6% (169/1760), 0.8% (14/1773) 4.8% (85/1773), respectively. The total prevalence of STDs was 14.9% (264/1776). Factors associated with HIV infection were illegal drug use ( adjusted OR = 17. 8; 95% CI: 4.0-78. 8), frequencies of visiting female sex workers in the past twelve months( adjusted OR= 8. 7;95% Cl: 1.9-39. 0), tattoos (adjusted OR =6. 6;95%CI:1.8-24. 0), surgical operation experiences (adjusted OR =6. 0;95% Cl: L 6-22. 5) and toothbrush sharing ( adjusted OR = 5.6; 95% CI: 1.0-31. 3). Factors associated with STDs infection were race (adjusted OR =2. 0;95%CI:1.5-2.7), age (adjusted OR= 1.7;95% CI:1.0-2.9), illegal drug use (adjusted OR =2.3;95%CI: L 0 -5. 2), living with spouses (adjusted OR= 1.4;95%ci: 1.11. 9) and visiting female sex workers (adjusted OR= 1.9;95%C1-.I.4 -2.6). Only 4.1% (49/1201)of respondents aware the correct transmission routes of HIV. 21.6% (339/1569) of the miners who had previous sexual experience self-reported visiting female sex workers. Conclusion HIV and other STDs are highly prevalent amongst miners in this region. In addition, the awareness of HIV/STDs is low and multiple routes of HIV transmission, such as heterosexual intercourse and IDU, were also observed in these study subject. HIV/STDs interventions should therefore be reinforced among the miners in this region.
