To analyze the trends of overweight and obesity of children and adolescents in 9 provinces of China from 1991 to 2015. A total of 14 888 children and adolescents aged 6-17 years with complete data were selected from the China Health and Nutrition Survey from 1991 to 2015. The definitions of overweight and obesity were defined using the international body mass index (BMI) cut-offs for child overweight and obesity established by the International Obesity Task Force in 2000 (hereinafter referred to as 'IOTF Standard'), the growth reference for school-aged children and adolescents established by the World Health Organization in 2007 (hereinafter referred to as 'WHO Standard'), the BMI cut-offs for screening overweight and obesity in Chinese children established by Li Hui et al. in 2009 (hereinafter referred to as 'Expert Standard'), and the screening thresholds for overweight and obesity in Chinese school-age children and adolescents released by the National Health and Family Planning Commission in 2018 (hereinafter referred to as 'Industry Standard'). Multivariable linear regression model was used to examine the trends in BMI values from 1991 to 2015, and multivariable logistic regression model was used to examine the trends in the prevalence of overweight and obesity from 1991 to 2015. After adjusting for the age, sex and region, BMI values increased from 17.26 kg/m(2) in 1991 to 18.72 kg/m(2) in 2015 ( value for trend <0.001). The prevalence of overweight defined by the IOTF Standard, WHO Standard, Expert Standard, and Industry Standard increased from 4.06%, 5.37%, 5.16%, and 4.27% in 1991 to 13.58%, 16.23%, 13.30%, and 11.70% in 2015, respectively (all values for trend <0.001), and the prevalence of obesity increased from 1.02%, 1.86%, 2.24%, and 2.41% in 1991 to 7.45%, 10.75%, 12.08%, and 12.74% in 2015, respectively (all values for trend <0.001). The BMI values and prevalence of overweight and obesity increased significantly in Chinese children and adolescents from nine provinces from1991 to 2015.
分析1991年至2015年中国9个省份儿童及青少年超重和肥胖的趋势。从1991年至2015年的中国健康与营养调查中选取了14888名6至17岁且数据完整的儿童及青少年。超重和肥胖的定义采用国际肥胖问题工作组2000年制定的儿童超重和肥胖国际体重指数（BMI）切点（以下简称“IOTF标准”）、世界卫生组织2007年制定的学龄儿童及青少年生长参考标准（以下简称“WHO标准”）、李辉等人2009年制定的中国儿童超重和肥胖筛查BMI切点（以下简称“专家标准”）以及国家卫生和计划生育委员会2018年发布的中国学龄儿童及青少年超重和肥胖筛查界值（以下简称“行业标准”）。采用多变量线性回归模型分析1991年至2015年BMI值的变化趋势，采用多变量逻辑回归模型分析1991年至2015年超重和肥胖患病率的变化趋势。在对年龄、性别和地区进行调整后，BMI值从1991年的17.26kg/m²增加到2015年的18.72kg/m²（趋势P值<0.001）。IOTF标准、WHO标准、专家标准和行业标准定义的超重患病率分别从1991年的4.06%、5.37%、5.16%和4.27%增加到2015年的13.58%、16.23%、13.30%和11.70%（所有趋势P值<0.001），肥胖患病率分别从1991年的1.02%、1.86%、2.24%和2.41%增加到2015年 的7.45%、10.75%、12.08%和12.74%（所有趋势P值<0.001）。1991年至2015年，中国9个省份儿童及青少年的BMI值以及超重和肥胖患病率显著增加。
