Dual Epidemics of Club Drug Use and Sexually Transmitted Infections among Chinese Female Sex Workers: New Challenges to STI Prevention

الملخص EN

Objectives.

To evaluate club drug use and its potential association with STI among female sex workers (FSWs) in China.

Methods.

From November 2008 to January 2009, participants were recruited at sex work venues in five cities for a questionnaire survey.

Free testing for syphilis, Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG) was provided.

Logistic regression models were used to assess factors associated with club drug use and its association with STI.

Results.

A total of 1604 eligible FSWs were included.

The overall prevalence of any STI infection and club drug use in the past 12 months was 22.6% and 7.4%, respectively.

STI prevalence was significantly higher among club drug users (33.1%) than among nonusers (21.7%, P<0.05).

Multivariable logistic regression found that club drug use was associated with younger age (AOR 2.4, 95% CI 1.0, 6.0), higher education, having injected drugs (AOR 24.4, 95% CI 6.2, 96.8), and having had STI symptoms (AOR 2.2, 95% CI 1.4, 3.4).

Conclusions.

Club drug use and STI were highly prevalent among FSWs in China, especially among young FSWs.

Club drug users had more risk behaviors and higher STI rates.

A coordinated risk reduction framework is urgently needed to address the dual epidemic of drug use and STI.
