title: [Study on the association between vaginal douching and sexually transmitted diseases among female sex workers in a county of Yunnan province].
abstract: OBJECTIVE
  To explore the epidemic characteristics of vaginal douching, human immunodeficiency virus (HIV) and other sexually transmitted diseases(STD) among female sex workers (FSWs) in Yunnan province.
  
  
  METHODS
  FSWs were recruited to be investigated on their demographic data, drug abuse and sexual behavior, HIV/AIDS knowledge and procreation health status. Venous blood were collected to test for HIV, herpes simplex virus 2 (HSV-2) and syphilis while urine specimen was for morphine, cervical secretion for Gonorrhoea and Chlamydia trachomatis, and vaginal secretion for Trichomonas.
  
  
  RESULTS
  A total number of 833 blood specimen were collected, in which 84 specimen were confirmed to be HIV positive with a prevalence rate of 10.1%. The prevalence rates of syphilis and HSV-2 were 8.2% and 68.4% respectively. 832 vaginal and cervical secretion specimen were collected with the prevalence rates of Gonorrhoea, Chlamydia trachomatis and Trichomonas were 11.5%, 28.2% and 11.9% respectively. In multivariate logistic analysis, the factors associated with vaginal douching were: being Han nationality, locations of sex work at middle/high level, ever heard of HIV/AIDS, emerged hypogastric pain last year, the number of sex work location > or =4.
  
  
  CONCLUSIONS
  Vaginal douching was shown a risk factor for HIV and some STD.
