Abstract
Objective
To estimate HIV prevalence among injecting drug users (IDUs) in a drug trafficking city in southwest Sichuan Province, China.
Methods
A total of 314 IDUs was invited to participate in the cross-sectional survey in 2004 through community outreach recruitment and peer referrals. Blood sample was taken for HIV antibody testing and a structured questionnaire was administered to collect information on socio-demographics, drug using and sexual behaviors.
Results
HIV prevalence among IDUs was 17.8% (56/314), about one half higher than that in previous survey in 2002 (11.3%, 43/379). Yi and other minority ethnicity (Odds ratio [OR], 3.1; 95% confidence interval [CI], 1.7?5.8; P < 0.001), and total times of sharing injecting equipments 1?9 times versus none, OR, 2.7; 95% CI 1.2?6.2; P = 0.02; and ?10 times versus none, OR, 7.5; 95% CI, 3.2?17.7; P < 0.001) were independent risk factors for HIV infection.
Conclusion
IDUs with high prevalence rates of HIV and equipment sharing behavior in the drug trafficking city may serve a source for further spread of HIV to other areas in China. The increasing trend of HIV epidemic among IDUs underscores the urgency of scaling up interventions.
