title: Dual Epidemics of Drug Use and Syphilis Among Chinese Female Sex Workers: Results of Eight Consecutive Cross-Sectional Surveys from 2006 to 2013 in Qingdao, China.
abstract: Eight consecutive annual cross-sectional surveys were conducted to examine the trend of the prevalence of HIV, syphilis, drug use and their correlates among female sex workers (FSWs) in Qingdao, China. Among sampled FSWs over the 8 years, a higher proportion of older, married or cohabited, higher education levels and more on-call FSWs were observed in recent years. The syphilis prevalence increased significantly from 1.0 % in 2006 to 13.5 % in 2013, with illicit drug use rate ranging from 21.8 % in 2007 to 55.5 % in 2010. Multivariate logistic regression analyses showed that drug use, syphilis and unprotected vaginal sex predicted each other. The dual epidemics of illicit drug use and syphilis among FSWs underscore the urgency to implement a tailored intervention to curb the dual epidemics while also preventing an HIV epidemic in the context of diversified commercial sex dynamic.
