To analyze the distribution characteristics and trends of overweight and obesity in children and adolescents aged 7-17 years in 16 provinces of China.
Data were collected from China health and nutrition survey in 2000, 2006, 2011, 2015 and 2018, 8398 children and adolescents aged 7-17 with complete data were selected as the research objects. Overweight and obesity were classified by body mass index(BMI) reference norm for screening overweight and obesity in Chinese children and adolescents. The distribution and trend of overweight and obesity among children and adolescents aged 7-17 in 16 provinces of China were analyzed by using Cochran-Armitage trend test and two-level random intercept model.
The prevalence of overweight and obesity in children and adolescents aged 7-17 in China showed an upward trend from 2000 to 2018(P<0.05). The prevalence of overweight increased from 5.42% in 2000 to 12.92% in 2018, and the prevalence of obesity increased from 2.45% in 2000 to 12.36% in 2018. The result of multilevel model analysis showed that gender and urban and rural areas had significant effects on centralized BMI(P<0.05), the BMI increase value of boys was greater than that of girls(β=0.2824), the BMI increase value of children and adolescents in rural areas was greater than that in urban areas(β=0.5902).
The prevalence of overweight and obesity among children and adolescents aged 7-17 in 16 provinces of China are increasing.
分析中国16个省份7-17岁儿童青少年超重与肥胖的分布特征及变化趋势。
收集2000年、2006年、2011年、2015年和2018年中国健康与营养调查数据，选取8398名7-17岁数据完整的儿童青少年作为研究对象。采用中国儿童青少年超重与肥胖筛查的身体质量指数（BMI）参考标准对超重与肥胖进行分类。运用Cochran-Armitage趋势检验和二级随机截距模型分析中国16个省份7-17岁儿童青少年超重与肥胖的分布及变化趋势。
2000年至2018年，中国7-17岁儿童青少年超重与肥胖患病率呈上升趋势（P<0.05）。超重患病率从2000年的5.42%升至2018年的12.92%，肥胖患病率从2000年的2.45%升至2018年的12.36%。多水平模型分析结果显示，性别和城乡地区对集中BMI有显著影响（P<0.05），男孩的BMI增加值大于女孩（β=0.2824），农村地区儿童青少年的BMI增加值大于城市地区（β=0.5902）。
