Characteristics of low-tier female sex workers who engage in commercial sex with old male clients in Zhejiang province, China: a cross-sectional study.

Objectives: To characterise low-tier female sex workers (FSWs) who engage in commercial sex with old male clients (OMCs).
Design: Cross-sectional study.
Setting: Twenty-one counties in Zhejiang province, China.
Participants: A total of 2647 low-tier FSWs who participated in our survey from September to November 2013, and responded to the question regarding whether they engaged in commercial sex with OMCs during the previous month.
Main Outcome Measures: Data on sociodemographic characteristics, sexual behaviours, risk perception of HIV/sexually transmitted infection (STI), ever exposure to an HIV prevention service and degree of self-efficacy regarding condom use were collected via a face-to-face questionnaire administered by trained interviewers.
Results: Of the 2647 participants, 1165 (44.0%) had engaged in commercial sex with OMCs in the previous month. Low-tier FSWs working out of roadside shops, those who had engaged in sex work for longer, those with a larger number of clients, those who had engaged in anal or oral sex during the previous month, those currently using contraception measures, those who had STI symptoms and those who had been exposed to HIV prevention services during the previous 6 months were more likely to engage in commercial sex with OMCs. FSWs with a high level of education; those working out of small venues other than streets, hair salons and roadside shops; those who charged more for commercial sex; those who had sex with young clients during the previous month and those who had seen a doctor during the previous 6 months were less likely to engage in commercial sex with OMCs.
Conclusions: Low-tier FSWs who engaged in commercial sex with OMCs reported more risky behaviours than those who did not engage in this behaviour. Attention should be paid to these behaviours in future interventions targeting low-tier FSWs.
