To study on the prevalence of body overweight and obesity in China and its distribution in age, sex and economic development status.
A total of 209,849 in all ages from the 2002 China National Nutrition and Health Survey (NNAHS) database were analyzed. The year 2000 population census data was used for age standardization. 1978 WHO criteria using Z scores was applied to age 0-7 years, criteria recommended by the Working Group on Obesity in China was applied to those aged 7-17 years and criteria in the Guidelines for Prevention and Control of Overweight and Obesity in Chinese Adults was applied to those aged 18 years and above.
The overall prevalence was 17.6% for overweight and 5.6% for obesity. The combined prevalence of overweight and obesity was 23.2%. The prevalence of overweight was 25.0%, 21.6%, 17.4%, 15.1%, 19.2% and 12.8%, respectively for large city, middle-and-small city, class 1 rural, class 2 rural, class 3 rural and class 4 rural. For obesity, the rate was 10.6%, 7.2%, 6.4%, 4.3%, 6.0% and 2.7%, respectively for large city, middle-and-small city, class 1 rural, class 2 rural, class 3 rural and class 4 rural. By age groups, the prevalence of overweight was 3.4% in children age 0-6, 4.5% in adolescents age 7-17, 22.8% in adults age 18 and above; the prevalence of obesity was 2.0% in children age 0-6, 2.7% in adolescents age 7-17, 7.1% in adults age 18 and above. The sex difference in overweight and obesity differed between urban and rural, and among age groups.
Overweight and obesity should have affected nearly 1 quarter of the country's total population, and became a threatening hazard to resident's health. As the urbanization progress, obesity might doubly increase. Prevention and control of this hazard should be urgently needed.
研究中国人群超重和肥胖的患病率及其在年龄、性别和经济发展状况方面的分布情况。
分析了2002年中国居民营养与健康状况调查（NNAHS）数据库中所有年龄段的209849人。采用2000年人口普查数据进行年龄标准化。0至7岁儿童采用1978年世界卫生组织基于Z评分的标准，7至17岁人群采用中国肥胖问题工作组推荐的标准，18岁及以上人群采用《中国成人超重和肥胖症预防控制指南》中的标准。
超重的总体患病率为(17.6%)，肥胖的总体患病率为(5.6%)。超重和肥胖的合并患病率为(23.2%)。大城市、中小城市、一类农村、二类农村、三类农村和四类农村的超重患病率分别为(25.0%)、(21.6%)、(17.4%)、(15.1%)、(19.2%)和(12.8%)。肥胖率在大城市、中小城市、一类农村、二类农村、三类农村和四类农村分别为(10.6%)、(7.2%)、(6.4%)、(4.3%)、(6.0%)和(2.7%)。按年龄组划分，0至6岁儿童超重患病率为(3.4%)，7至17岁青少年超重患病率为(4.5%)，18岁及以上成年人超重患病率为(22.8%)；0至6岁儿童肥胖患病率为(2.0%)，7至17岁青少年肥胖患病率为(2.7%)，18岁及以上成年人肥胖患病率为(7.1%)。超重和肥胖的性别差异在城乡之间以及不同年龄组之间有所不同。
超重和肥胖已影响到近四分之一的中国人口，对居民健康构成威胁。随着城市化进程的推进，肥胖问题可能会加倍增加。迫切需要对这一危害进行预防和控制。
