| Objective: To investigate the incidences and correlating factors ofcommon vaginitis among outpatients in the department of gynecology.Methods: The microscopic examination, PH values and whiff testwere carded out in 172748 outpatients between January 2002 andDecember 2005, were involved. Data of the outpatients includingincidence,age and season were analyzed by Chi-square test.Results:①. 25.8% of the outpatients were positive for vaginitis.Positive result of various type of vaginitis were vulvovaginal candidiasis19.38%, bacterial vaginosis 4.48%, trichomonal vaginitis 1.93%.②. Detection rate of vulvovaginal candidiasis was deceasing year by year(P＜0.05), while in autumn and winter was obviously higher than that inspring and summer (P＜0.05). The age distribution of vulvovaginalcandidiasis were lower among the out-patients above 50 years comparedwith 20～50 years (P＜0.05), but no significant differences between 20～50years and those at ages below 20 years (P＞0.05).③. The rate of bacterialvaginosis were increasing year by year (P＜0.05), and the lowest was inspring of a year (P＜0.05). There was no differences in summer,autumnor winter(P＞0.05). The age distribution of bacterial vaginosis were lowerabove 50 years compared with 20～50years (P＜0.05). there were nosignificant differences between 20～50years and those at ages below 20years (P＞0.05).④Detection rate of trichomonal vaginitis weredecreasing year by year (P＜0.05), that the highest was in spring of a year(P＜0.05). There was no differences in summer,autumn or winter(P＞0.05). The age distribution of trichomonal vaginitis were higherabove 50 years compared with 20～50 years (P＜0.05), there were nosignificant differences between 20～50 years and those at ages below 20years (P＞0.05).Conelusion:①The incidence ofvulvovaginal candidiasis is thehighest in the vaginitis.②Vaginitis were prevalent in the child-bearingage of women.③Vaginitis seems to be related with change of season.
