摘要
目的分析北京市2-18岁儿童青少年超重和肥胖检出率水平及分布特征。方法利用2004年北京市儿童代谢综合征调查总样本中21 198名2-18岁人群的体重指数数据,分别采用中国(WGOC标准)、美国疾病预防控制中心(CDC 2000标准)和国际肥胖工作组(IOTF标准)推荐的儿童青少年超重和肥胖体重指数分类标准计算超重和肥胖检出率。结果北京市2-18岁儿童青少年合并超重(包括肥胖)检出率、肥胖检出率分别是18．6％和8．1％(CDC 2000标准),17．4％和5．1％(IOTF标准);根据WGOC计算的7-18岁合并超重检出率和肥胖检出率是20．9％和8．9％。学龄儿童(6-18岁)的合并超重率高于学龄前儿童(19．8％:14．8％,CDC 2000标准);学龄儿童中,男性高于女性(26．7％:16．5％,WGOC标准),城市高于农村(27．0％:15．9％,WGOC标准);学龄前儿童城乡间差异无统计学意义。结论北京市有1／5的儿童青少年超重或肥胖,居国内最高水平。儿童青少年肥胖已经成为北京市一个重要公共卫生问题,需要引起社会高度关注。
Objective To determine the current prevalence of overweight and obesity among children and adolescents （2-18 years） in Beijing and its distribution by age, gender and urban-rural residence. Methods As part of the Beijing Child and Adolescent Metabolic Syndrome Study, a stratified cluster representative sample of 23 422 children aged 0-18 years was selected. Anthropometric measures including weight and height were collected from 21 198 subjects aged 2-18 years from April to October in 2004. Overweight and obesity were defined according to body mass index [BMI,weight（kg）/height（m^2） ] cutpoints. For national and international comparisons, three sex-age-specific BMI criteria were used：1） The BMI cutoffs recommended by the Chinese Working Group on Obesity for Children（WGOC） aged 7-18 years; 2） The US 2000 CDC Growth Charts （CDC 2000） frac 34, the 85th and 95th percentiles; 3） The international Obesity Task Force （IOTF） reference. Results The overall combined prevalence of overweight and obesity was 18.6% with obesity as 8.1% based on the CDC 2000 criteria, The figures were 17.4% and 5.1% based on the IOTF criteria. According to the WGOC criteria, the combined prevalence of obesity was 20.9 % and 8.9% in children aged 7-18 years. The combined prevalence was higher in school-age children （6-18 years） than in preschool-age children （19.8 % vs. 14.8 % ,based on the CDC 2000 criteria）. Among school-age children, the prevalence was higher in boys than in girls （26.7 % vs. 16.5 % ）, in urban than in rural areas （27.0 % vs. 15.9 % ）. However, these differences were not observed in preschool-age children. It was estimated that approximately 450 000 children from 2 through 18 years of age,were overweight or obesity in Beijing. Conclusion Data from our study indicated that one fifth of the children and adolescents in Beijing were under overweight or obesity situation which was the highest in the nation. Obesity among children and adolescents in Beijing had already become a serious public health problem which deserved greater attention.
