Abstract: Objective To analyze the status quo of overweight and obesity among school-age children in Pudong New Area of Shanghai,so as to provide direction for further screening overweight school-age children and preventing school-age children from obesity. Method A total of 1 738 school-age children in Pudong New Area of Shanghai were randomly selected for physical measurement and questionnaire survey in October 2017.Different standards of BMI,waist circumference and waist-to-height ratio were used to evaluate the overweight and obesity status of school-age children. Results Using BMI criteria for overweight and obesity assessments would leave out children at risk of central obesity,and the missing rate was 7.6%-16.2%.Moreover,2.8%-10.9% of school-age children with systemic obesity would be neglected only using the criteria of central obesity.The overweight and obesity rate of school-age children was the highest (28.6%-39.4%) in the suburban central town of Pudong New Area,Shanghai.The systemic overweight and obesity rate of boys was 26.2%-35.5%,which was apparently higher than that of girls,(18.1%-26.4%).Significantly,the study found that the proportion of girls with above-normal waists (254/766) was similar to that of boys (316/946) (χ²=0.011,P>0.05).In addition,the overweight and obesity rate of first-and second- grade children was significantly lower than that of third grade(P＜0.05). Conclusions School-age children should be screened for both systemic and central obesity criteria,so as to prevent overweight and obese as soon as possible.Besides,corresponding intervention strategies are suggested to be formulated.
