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.

Objective : To investigate the behavior problems and influencing factors of school-age students from the third to the sixth grade in Zhongshan,and to provide evidence for early intervention of behavior problems in children. Methods : According to the proportion of population in urban area and township in Zhongshan,students of Grade Three to Six from eight primary schools（three in urban area and five in township）were recruited by stratified sampling method. The behavior problems in children were assessed by the Conners Parent Symptom Questionnaire（PSQ）. Sociodemographic information,family discipline and so on was investigated by a general questionnaire. The influencing factors for behavior problems were analyzed by a logistic regression model. Results : A total of 2 292 questionnaires were issued,and 2 236 valid questionnaires were recycled,with an effective rate of 97.56%. The positive rate of behavioral problems was 11.72%. The results of multivariate logistic regression analysis showed that the risk factors for behavior problems were females（OR=1.594,95%CI：1.170-2.171）,birth asphyxia（OR=2.372,95%CI：1.320-4.261）,main family discipline（laissez-faire：OR=3.326,95%CI：1.450-7.630;doting：OR=3.244,95%CI：1.867-5.638;autocratic：OR=2.609,95%CI：1.584-4.296,mixed：OR=2.313,95%CI：1.669- 3.207）,less than four hours per week for father-child communication（OR=1.551,95%CI：1.052-2.286）,negative life events（OR=2.188,95%CI：1.448-3.308）,living in township（OR=2.031,95%CI：1.330-3.102）,academic performance （average：OR=2.786,95%CI：1.868-4.156;poor：OR=6.665,95%CI：3.236-13.727;very poor：OR=25.068,95%CI：5.786-108.617）;the protective factors were occupation of mother as civil servants or professional personnel（OR=0.449,95%CI：0.238-0.844）and higher grades（Grade Five：OR=0.496,95%CI：0.339-0.727;Grade Six：OR=0.468,95%CI：0.309-0.710）. Conclusion Females,birth asphyxia,main family discipline,less communication between father and child,occupation of mother,negative life events,place of residence,academic performance and grade were the influencing factors for behavior problems.

Objective: To analyze the status of excess heart age and its risk factors among Chinese residents aged 35 to 64 years. Methods: The study subjects were Chinese residents aged 35 to 64 years who completed the heart age assessment by WeChat official account "Heart Strengthening Action" through the internet from January 2018 to April 2021. Information such as age, gender, body mass index (BMI), blood pressure, total cholesterol (TC), smoking history, and diabetes history was collected. The heart age and excess heart age were calculated according to the characteristics of individual cardiovascular risk factors and the heart aging was defined as excess heart age≥5 years and 10 years respectively. The heart age and standardization rate were calculated respectively based on the population standardization of the 7th census in 2021.CA trend test was used to analyze the changing trend of excess heart age rate and population attributable risk (PAR) was used to calculate the contribution of risk factors. Results: The mean age of 429 047 subjects was (49.25±8.66) years. The male accounted for 51.17% (219 558/429 047) and the excess heart age was 7.00 (0.00, 11.00) years. The excess heart age rate defined by excess heart age≥5 years and ≥10 years was 57.02% (the standardized rate was 56.83%) and 38.02% (the standardized rate was 37.88%) respectively. With the increase of the age and number of risk factors, the excess heart age rate of the two definitions showed an upward trend according to the result of the trend test analysis (P<0.001). The top two risk factors of the PAR for excess heart age were overweight or obese and smoking. Among them, the male was smoking and overweight or obese, while the female was overweight or obese and having hypercholesterolemia. Conclusion: The excess heart age rate is high in Chinese residents aged 35 to 64 years and the contribution of overweight or obese, smoking and having hypercholesterolemia ranks high.
