Abstract:
Objective:To analyze the vulvovaginal microecological characteristics of young girls and the impact of age on these characteristics.Methods:A total of 371 young girls aged≤12 years who visited the department of Gynecological,Peking University First Hospital from January 2016 to December 2022 were selected.These girls were stratified into three age groups:＜7 years,7-9 years,and＞9-12 years.Then,the results of their vulvovagi-nal microecology were analyzed.Results:A total of 84 cases(22.6％)were clinically diagnosed with vulvovagini-tis,including 43 cases(43/84,51.2％)of bacterial vaginosis(BV),38 cases(38/84,45.2％)of vulvovaginal can-didiasis(VVC),2 cases(2/84,2.4％)of trichomoniasis vaginalis(TV),and 1 case(1/84,1.2％)of mixed vul-vovaginitis(BV+VVC).It was found that there was a statistically significant difference in VVC infection among different age groups of young girls(P＜0.001),and the infection rate was higher in the＞9-12 years group.Sig-nificant variations were also observed in BV infection among different age groups of young girls(P＜0.001).The infection rate was the highest in the 7-9 years group and the lowest in the＞9-12 years group.Among the 371 patients,165 cases(44.5％)had normal vaginal flora,176 cases(47.4％)had abnormal vaginal flora.Among them,64 cases(17.3％)had BV-type abnormal flora,and 112 cases(30.2％)had non-BV-type abnormal flora.There were 30 cases(8.1％)with flora suppression.The composition ratios of flora suppression,BV-type abnor-mal flora,non-BV-type abnormal flora,and total abnormal flora demonstrated statistically significant intergroup var-iations across age cohorts(P＜0.001).Microecological analysis showed that there were statistically significant differences in the composition ratios of factors such as dominant bacteria(Gram-positive large bacilli)and pH a-mong different age groups(P＜0.001).Conclusions:The composition of the vulvovaginal microecology varies a-mong young girls of different ages,and differences exist in reproductive tract infections across these age groups.Assisting in diagnosis through vulvovaginal microecology can better guide clinicians to provide targeted treatment for reproductive tract infections in young girls,and improve the clinical cure rates.
