Methods In 2010-05, female sex workers were recruited from Xichang community, and their social demography, first sexual behavior and first commercial sexual behavior were investigated. Results A total of 404 female sex workers were surveyed. The incidence rate from first sex to first commercial sex was 18.65 / 100 person-years (95% CI = 16.83 to 20.47). In the multivariate Cox proportional hazards model, the first-time sexual partners (RR = 1.29, 95% CI = 1.05-1.60), ethnic groups (RR = 1.82, 95% CI = 1.28-2.59) % CI = 1.56 ~ 2.53) is the difference of the first commercial sexual behavior among female sex workers. Conclusion It is necessary to further study the occurrence of the first commercial sexual behaviors of female sex workers and its influencing factors so as to provide a scientific basis for carrying out targeted health education and behavioral interventions.
