Obesity Prevalence and Time Trend among Youngsters in China, 1982-2002
中国儿童肥胖率及1982－2002年间变化趋势
摘要
为了了解中国7－17岁儿童超重肥胖现况及其过去二十年间的变化趋势，以及超重肥胖儿童中生长迟缓者所占的比例，利用三个有全国代表性的营养调查，即1982年中国营养调查（男孩5,334人；女孩4,793人）、1992年中国营养调查（男孩8,048人；女孩7,453人）和2002年中国居民营养与健康状况调查（男孩23,242人；女孩21,638人）数据进行分析。根据国际肥胖工作组推荐的年龄别性别体质指数标准定义儿童超重和肥胖，生长迟缓定义为身高低于NCHS/WHO Z评分标准的2个标准差。结果表明，1982、1992和2002年我国7－17岁儿童超重率分别为1.2%、3.7%和4.4%，肥胖率分别为0.2%、0.9%和0.9%。城市男孩的超重肥胖率及其增长均最高。1982年有28.4%的超重儿童同时生长迟缓（身高发育不足），肥胖儿童中该比例更高，达到69.6%。1992年超重和肥胖儿童中合并生长迟缓的比例分别为22.0%和46.4%，到2002年，这两个比例分别降到5.7%和7.7%。本研究认为虽然1982年中国儿童肥胖尚不成问题，但从1992年迅速上升。同时，生长迟缓性肥胖在肥胖儿童中的比例逐渐下降。

Purpose of present study is to describe the prevalence and trend of overweight and obesity, as well as its coexistence 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 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. Results: 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. Conclusion: 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.
