An epidemiological study on vaginitis in 6,150 women of reproductive age in Shanghai

The aim of the present study was to determine the prevalence and risk factors for vaginitis, the proportion of pathogens, and cognition of reproductive age patients on the harmful effects of vaginitis, its risk factors, and treatment.

The positive pathogen rate was 65.63% (4,036/6,150). Trichomonas infections were diagnosed in 1,416 (35.08%) cases including 761 (18.86%) cases of single trichomonas infections, which was significantly higher than the proportion of any other single pathogen infection (P
