Little information is available on the trends in severe pediatric obesity in China. Therefore, we aimed to examine the trends in overweight, obesity, and severe obesity in Chinese children from 1991 to 2015. Overall, 17,004 children aged 6-17 years were included in this study, which was based on the China Health and Nutrition Survey 1991-2015. We defined overweight [BMI ≥85th percentile], obesity (BMI ≥95th percentile), and severe obesity (BMI ≥120% of the 95th percentile, or 35 kg/m) according to the U.S. Centers for Disease Control and Prevention Growth Charts. Controlling for age, sex, and region, we performed multivariate analyses to assess secular trends in the prevalence of overweight, obesity, and severe obesity in the pediatric population. During 1991-2015, the prevalence of overweight increased from 4.6% to 21.1%, of obesity from 1.4% to 10.1%, and of severe obesity from 0.2% to 4.0% (relative increases of 358.7%, 621.4% and 1900.0% in overweight, obesity, and severe obesity, respectively). We observed a significant positive trend in the prevalence of overweight, obesity, and severe obesity in the pediatric population [odds ratios (95% confidence intervals): 1.23 (1.21, 1.26), 1.30 (1.26, 1.34), and 1.52 (1.41, 1.63), respectively; all < 0.001]. These results did not differ significantly between subgroups of sex, age, and region, or when Chinese national reference standards were used. The prevalence of childhood overweight, obesity, and particularly severe obesity in China increased significantly from 1991 to 2015.
在中国，关于严重儿科肥胖趋势的信息有限。因此，我们旨在研究 1991 年至 2015 年期间中国儿童超重、肥胖和严重肥胖的趋势。本研究共纳入了 1991-2015 年中国健康与营养调查中 17004 名 6-17 岁的儿童。我们根据美国疾病控制与预防中心的生长图表，将超重（BMI≥第 85 百分位数）、肥胖（BMI≥第 95 百分位数）和严重肥胖（BMI≥第 95 百分位数的 120%，或 35kg/m²）定义为。控制年龄、性别和地区，我们进行了多变量分析，以评估儿科人群中超重、肥胖和严重肥胖患病率的长期趋势。1991-2015 年间，超重的患病率从 4.6%增加到 21.1%，肥胖的患病率从 1.4%增加到 10.1%，严重肥胖的患病率从 0.2%增加到 4.0%（超重、肥胖和严重肥胖的相对增长率分别为 358.7%、621.4%和 1900.0%）。我们观察到儿科人群中超重、肥胖和严重肥胖的患病率呈显著正趋势[比值比（95%置信区间）：1.23（1.21, 1.26）、1.30（1.26, 1.34）和 1.52（1.41, 1.63）；均<0.001]。这些结果在性别、年龄和地区亚组之间或使用中国国家参考标准时没有显著差异。1991 年至 2015 年期间，中国儿童超重、肥胖，尤其是严重肥胖的患病率显著增加。
