Objective: To investigate the prevalence and associated factors of eating out among children and adolescents aged 6-17 in Hebei Province, and to explore the association between eating out and overweight/obesity. Methods: Data came from Children and Nurse Nutrition Health Monitoring of China during 2016-2017. Questionnaire surveys and anthropometric measures was conducted among 3 330 children aged 6-17 in 12 survey sites. Multivariate Logistics stepwise regression model was used to analyze the influencing factors of eating out and the relationship between eating out and overweight/obesity. Results: The proportion of eating out was 16.19%, and the rate of overweight and obesity was 29.43%. Multivariate analysis showed that the older children (junior high school students:OR=1.36; high school students:OR=3.57, both P<0.05) and adolescents from highincome families (10 000~<20 000 CNY:OR=1.48; ≥20 000 CNY:OR=2.93, both P<0.05) were more likely to eat out. Children and adolescents living in rural areas (OR=0.20, P<0.01), nononlychild (OR=0.76, P=0.02), day school students (OR=0.21, P<0.01), and the primary caregivers of the elderly (OR=0.69, P=0.03) were less likely to eat out. In addition, eating out was statistically associated with an increased risk of overweight and obesity (OR=1.31, P<0.01). Conclusion Eating out is common among children and adolescents aged 6-17 in Hebei Province. Residency, age, household income, onechild family, boarding and and eating out behaviors of primary caregivers are associated with eating out among children and adolescents. Eating out may increase the risk of overweight/obesity in children.

Objective: To investigate the safety and efficacy of transcatheter closure of ruptured sinus of Valsava aneurysm(RSVA). Methods: A total of 33 RSVA patients underwent transcatheter closure from January 2006 to March 2017 in our hospital were included in this retrospective study. The RSVA was diagnosed by echocardiography.Different type of occluders were applied for transcatheter closure based on the aortography results. All the patients were followed up after the procedure. Results: The patients were (37.6±12.1) years old,and the male patients accounted for 78.8%(26 cases).RSVA from right coronary sinus was found in 25 patients,and draining chamber was right atrium in 13 cases, right ventricle in 12 cases. RSVA from noncoronary sinus was diagnosed in 8 patients,and the draining chamber was right atrium. Aortography defined the narrowest diameter at the rupture site was (6.4±1.7)mm. The ratio of Qp/Qs was 2.2±0.5,and the mean pressure of pulmonary artery was 24.0(21.2,33.7)mmHg(1 mmHg=0.133 kPa). One patient developed serious occluder related aortic regurgitation and underwent surgery, transcatheter closure was successfully performed in 32 patients. The success rate of transcatheter closure was 97.0%. Two types of device were used in the study including small-waist double-disk ventricular septal defect(VSD) occluders in 20 cases and patent ductus arteriosus(PDA) occluders in 12 cases. During a median follow-up of 73.5(28.3,89.5) months, there were no infective endocarditis, residual shunt, thrombosis, device displacement,serious aortic regurgitation, serious arrhythmia or death.At the last follow-up, the left atrial diameter((37.4±6.5) mm vs. (41.5±5.3)mm,P<0.01),right atrial diameter((42.4±3.0) mm vs. (48.5±6.0)mm,P<0.01), right ventricular diameter((22.2±3.8) mm vs. (27.7±7.2)mm,P<0.01) and left ventricular end-diastolic diameter((51.3±4.9) mm vs.(55.0±4.3)mm,P<0.01)measured by echocardiography were all smaller than pre-procedural level. Conclusion Transcatheter closure of RVSA is a safe and effective strategy and associated with a good long-term outcome.
