Abstract: Objective To analyze the trends of overweight and obesity among children and adolescents aged 6 to 17 years from 2009 to 2018 in Shanghai, in order to provide evidence for the prevention and control of overweight and obesity in children and adolescents. Methods A total of 523 112 children and adolescents aged 6 to 17 years with complete data were selected from students' common diseases surveillance program in Shanghai from 2009 to 2018.Overweight and obesity were defined using the growth reference for school-age children and adolescents established by the World Health Organization in 2007 (here in after referred to as WHO standard).Multivariate linear regression model was used to examine the trends in body mass index(BMI), and multivariate Logistic regression model was used to examine the trends in the prevalence of overweight and obesity. Results The total detection rates of overweight and obesity among children and adolescents aged 6 to 17 years in Shanghai in 2018 were 19.37% and 10.78%.The detection rates of overweight and obesity were 22.33% and 16.27% for boys, and 16.31% and 5.13% for girls, respectively, which were significantly higher in boys than those in girls (χ²=253.26, 1 404.73, P<0.001).After adjusting for the age and sex, the rate of overweight and obesity increased from 16.94% and 9.22% in 2009 to 19.37% and 10.78% in 2018, respectively (P_trend<0.001). Conclusions BMI and the rate of overweight and obesity of children and adolescents aged 6 to 17 years in Shanghai show an increasing trend from 2009 to 2018.The growth rate of overweight and obesity tends to be flat, but it is still prevalent.
