Female sex workers (FSWs) have become one of the key populations for HIV/STI control in China. Categorization of FSWs can help prioritize HIV/STI intervention efforts. We examined two possible categorizations of FSWs and the relationship with syphilis infection risk in Liuzhou City, China. From October 2009 to February 2010, a total of 583 FSWs recruited by respondent-driven sampling in a cross-sectional survey were tested for syphilis and interviewed to collect socio-demographic and behavioural information. Respondents were categorized based on transaction price for vaginal sex and type of sex work location. The relationship between the two categorizations and syphilis infection risk was assessed using univariate and multivariate logistic regression analysis. The prevalence rates of lifetime and active syphilis infection were 8.6% and 4.1% respectively. Lifetime and active syphilis prevalence were higher among FSWs in the lowest price category (52.7% and 25.4% respectively) and those working in streets (69.7% and 39.8% respectively) or through telephone (46.3% and 17.0% respectively). Multivariate analysis showed that lifetime syphilis prevalence was significantly higher among street-(Adjusted odds ratio AOR 38.7, 95% CI 10.7-139.9) and telephone-based FSWs (AOR 10.8, 95% CI 3.3-35.1), and that active syphilis prevalence was significantly higher among street-based FSWs (AOR 15.2, 95% CI 3.7-62.1) after adjusting for demographic and behavioural factors. Categorization based on sex work location was more closely related to the risk of syphilis infection than the price classification. Street- and telephone-based FSWs had significantly higher risk of syphilis infection. Focused interventions among these particular high-risk FSWs subgroups are warranted.
