ABSTRACT
Objective To explore the distribution of age,reasons for treatment,risk factors,and causes of vulvovaginitis in prepubertal girls.Methods A total of 4 214 prepubertal girls with vulvovaginitis who were admitted to the Girl's Sub-department,Zhongshan Boai Hospital from January 2010 to June 2013 was reviewed retrospectively.All clinical data were from medical records with files.Results Atotalof1 587 patients (37.7％) was0to1 years old,954 (22.6％) ＞ 1 to3 years old,1 289 (30.6％) ＞ 3 to 7 years old,and 384 (9.1％) ＞ 7 years old.Many risk factors were associated with vaginitis,including poor hygiene (2 924 girls; 69.4％),allergies and exposure to allergens (875 girls; 20.8％).Most common reason for treatment was a referral from physical examination accounting for 919 girls (21.8％),followed by vaginal secretions 812 girls (19.3％).The causes of vulvovaginitis of all patients were evaluated,1 771 of which (42.0％) were nonspecific vulvovaginitis,1 309 (31.1％) labial adhesions,375 (8.9％) bacterial vulvovaginitis,266 (6.3％) allergic vulvovaginitis,and 266 (6.3％) affective leg rubbing action.Conclusions Prepubertal vulvovaginitis occurred mainly in infancy and preschool.Floating population was common.They were caused by many risk factors including poor hygiene,allergies,poor urination habits,etc.The most common causes of vulvovaginitis were nonspecific vulvovaginitis and labia adhesion,yet allergies and affective leg rubbing action were the more common causes of recurrent vulvovaginitis.We propose that focusing on girls' reproductive health,timely treating allergic and crossing rub legs and other diseases would help reduce the prevalence of vulvovaginitis in the prepubertal girls.
