Objective: To describe the different characteristics between full-time sex workers (FTSW) and part-time sex workers (PTSW) in Guangzhou, China, and to de-termine the risk factors which lead to the significantly higher prevalence of gonorrhea and trichomoniasis among FTSW. Methods: From March 1998 to October 1999 female sex workers were recruited through various outreach methods, and were interviewed and tested for the pres-ence of sexually transmitted diseases (STDs). In terms of additional regular salary female sex workers were divided into FTSW who didn't have additional regular salary and PTSW who had additional regular salary.Univariate and multivariate logistic regression analy-ses were used to identify risk factors for gonorrhea/trichomoniasis and to determine the confounders in the relationship between no regular salary and gonor-rhea/ trichomoniasis. Results: A total of 442 FTSW and 524 PTSW en-tered this study. Prevalence of gonorrhea and tri-chomoniasis was significantly higher in FTSWcompared to PTSW. FTSW were more likely tohave a lower education level, have a history of inject-ing drugs use since 1990, to recruit clients in a mas-sage/sauna, have businessmen as their clients and not have a steady partner compared to PTSW. In bivariate analyses models, age leaving education, main types of clients and recruitment locations appeared to be the strongest links between no regular salaried position and gonorrhea.A history of injecting drugs and hay-ing no steady partner (past 12 months) appeared to be the strongest links in the relationship between no regu-lar salaried position and trichomoniasis. Conclusion: Different education levels, clients, and recruitment locations between FTSW and PTSW may account for the different gonorrhea prevalence among sex workers. The higher prevalence of trichomonia-sis among FTSW may be related to the larger propor-tion of women having no steady partner or a history of injecting drugs. The results suggest strategies to prevent HIV/STDs among female sex workers should include condom negotiation with clients and aware-ness of seeking health care.
