[Prevalence and characteristics of overweight and obesity in Chinese children aged 0-5 years].

Objective: To study the prevalence and characteristics of overweight and obesity among Chinese children aged 0-5 years, in 2010-2013. Methods: Data was from the'China Nutrition and Health Surveillance-0-5-Years-Old Children and Lactating Women'project in 2013. Stratified multistage cluster sampling method was used to select 55 districts/counties from 30 provinces (autonomous regions, municipalities) with the sample size of children as 32 862. Definition of overweight and obesity were according to both the WHO 2006 growth standard in children less than 5-year-old and the WHO 2007 growth reference in children of 5-years-old. Results: were calculated by complex weight based on national census from the National Bureau of Statistics in 2010. Results The overall prevalence of overweight was 8.4% among the 0-5-year-old in 2013, with 9.4% in boys and 7.2% in girls. Both of the rates from urban and rural areas were the same, as 8.4%. The prevalence rates of overweight in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups appeared as 13.0%, 11.1%, 8.3%, 6.0%, 4.8%, 3.9% and 15.9%, respectively. The rates of overweight in low, medium and high income families were 8.0%, 8.8% and 8.9%, respectively. The prevalence of obesity was 3.1% among the 0-5-year-old, with 3.6% in boys and 2.5% in girls. There was no significant difference seen in urban (3.3%) and rural areas (2.9%). The prevalence rates for obesity in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups were 5.8%, 3.8%, 2.5%, 1.6%, 1.2%, 1.3% and 7.8%, respectively. The rates of obesity in low, medium and high income families were 2.8%, 3.3% and 3.5%, respectively. Conclusion: The prevalence rates of both overweight and obesity were increasing among the 0-5-year-olds in China, suggesting that it is necessary to timely conduct the surveillance and intervention programs on overweight and obesity in this target population.目的： 研究中国0~5岁儿童的超重肥胖现况及其分布特点。 方法： 数据来自"2010－2013年中国居民营养与健康状况监测"数据，2013年儿童调查采用多阶段分层整群抽样的方法，研究对象为全国30个省（自治区、直辖市）55个调查县（区）中0~5岁儿童32 862名。超重肥胖的判定：5岁以下儿童采用WHO 2006年生长发育标准；5岁儿童采用WHO 2007年生长发育参考值。结果采用2010年国家统计局的人口数据进行复杂加权计算。 结果： 2013年中国0~5岁儿童超重率为8.4%，男童和女童超重率分别为9.4%和7.2%；城、乡儿童超重率均为8.4%。0~、6~、12~、24~、36~、48~和60~71月龄组超重率分别为13.0%、11.1%、8.3%、6.0%、4.8%、3.9%和15.9%；家庭低、中和高收入水平儿童超重率分别为8.0%、8.8%和8.9%。0~5岁儿童肥胖率为3.1%，男童和女童肥胖率分别为3.6%和2.5%；城市和农村儿童肥胖率分别为3.3%和2.9%。0~、6~、12~、24~、36~、48~和60~71月龄组儿童的肥胖率分别为5.8%、3.8%、2.5%、1.6%、1.2%、1.3%和7.8%；低、中和高收入水平儿童肥胖率分别为2.8%、3.3%和3.5%。 结论： 中国0~5岁儿童的超重和肥胖率正在增高攀升，及时监测0~5岁儿童的超重肥胖状况和实施合理干预十分必要。.
