Sexual transmission is the fastest growing route of HIV transmission in China, and Trichomonas vaginalis(TV) can facilitate HIV transmission and acquisition. Our goal was to determine the prevalence and correlates of TV infection among female sex workers (FSWs). This cross-sectional study was conducted in a city of Yunnan Province in southern China, with confidential face-to-face interviews and laboratory tests for TV (wet mount) and other sexually transmitted infections. A total of 734 FSWs participated in the study. The prevalence of TV was 9.0% (95% confidence interval [CI] 7.02-11.30). In multivariate analyses, adjusted odds ratios of TV infection were 3.0 (95% CI 1.47-6.01) for herpes simplex virus type 2 seropositive, 2.4 (95% CI 1.37-4.14) for Chlamydia trachomatis infection, 2.6 (95% CI 1.30-5.31) for genital ulcer, 1.9 (95% CI 1.11-3.30) for starting age in commercial sex <20 years, and 0.5 (95% CI 0.27-0.87) for vaginal douching. We found a relatively high prevalence of TV infection among FSWs in Yunnan Province. A range of control strategies that include TV screening are recommended among FSWs, which could contribute significantly to the disruption of transmission by the provision of immediate treatment.
