Purpose of present study is to describe the prevalence and trend of overweight and obesity, as well as its co-existence with stunting, among youngsters in China, from 1982 to 2002. Data from children 7-17 years of age from three cross-sectional national surveys: "1982 China National Nutrition Survey" (5,334 boys and 4,793 girls), "1992 China National Nutrition Survey" (8,048 boys and 7,453 girls) and "2002 China National Nutrition and Health Survey" (23,242 boys and 21,638 girls) were used in this study. Overweight and obesity were defined according to age, sex and specific BMI cut-off points from the International Obesity Task Force, while stunting was defined as height-for-age below -2 standard deviation from the NCHS/WHO reference median value.
Overweight prevalence of Chinese youngsters was 1.2%, 3.7% and 4.4%, while the obesity prevalence was 0.2%, 0.9% and 0.9% in 1982, 1992 and 2002, respectively. Both the overweight and obesity prevalence and their increment were higher among boys in urban areas. In 1982, 28.4% of overweight and 69.6% of obese youngsters were stunted, this decreased to 22.0% and 46.4% in 1992, and then to 5.7% and 7.7% in 2002, respectively.
The prevalence of overweight and obesity in Chinese youngsters were low in 1982. There has been a rapid increase since then. If this trend continues, overweight will soon reach epidemic proportions. Stunting among overweight and obese youngsters decreased dramatically at the same time.
本研究的目的是描述1982年至2002年中国青少年超重和肥胖的患病率及趋势，以及其与发育迟缓的共存情况。本研究使用了来自三项全国横断面调查中7至17岁儿童的数据：“1982年中国国家营养调查”（5334名男孩和4793名女孩）、“1992年中国国家营养调查”（8048名男孩和7453名女孩）以及“2002年中国国家营养与健康调查”（23242名男孩和21638名女孩）。超重和肥胖根据国际肥胖特别工作组的年龄、性别和特定BMI切点来定义，而发育迟缓则定义为身高低于美国国家卫生统计中心/世界卫生组织参考中位数-2个标准差。
1982年、1992年和2002年中国青少年的超重患病率分别为1.2%、3.7%和4.4%，肥胖患病率分别为0.2%、0.9%和0.9%。城市地区男孩的超重和肥胖患病率及其增幅均更高。1982年，28.4%的超重青少年和69.6%的肥胖青少年发育迟缓，1992年这一比例降至22.0%和46.4%，2002年则分别降至5.7%和7.7%。
1982年中国青少年超重和肥胖的患病率较低。此后患病率迅速上升。如果这种趋势持续下去，超重将很快达到流行程度。与此同时，超重和肥胖青少年中的发育迟缓现象大幅下降。
