中国10省（自治区）农村学龄前儿童超重/肥胖现状调查

Survey on overweight and obesity of preschool children in rural areas from ten provinces of China

目的 了解中国10省（自治区）农村学龄前儿童超重/肥胖的发生情况.方法 利用“2006年中国10省农村7岁以下儿童体格发育调查”资料,选取学龄前儿童作为研究对象,以体重超过同性别、同身高参照人群均值的10％为超重,超过20％者为轻度肥胖,超过30％者为中度肥胖,超过50％为重度肥胖.利用SPSS 13.0软件对数据进行统计学分析.运用X2检验进行率的比较.结果 共纳入38 923名儿童,超重检出率为4.18％,男童的超重检出率高于女童（x2=4.343 6,P=0.037 1）,3～岁组儿童超重检出率最高（5.80％）;肥胖检出率为1.21％,以轻度肥胖为主（0.78％）,男、女童肥胖检出率差异无统计学意义（X2=0.389 0,P=0.532 8）,其中6～岁组的肥胖检出率最高（1.42％）;10省（自治区）农村超重检出率为1.38％～ 7.62％,肥胖检出率为0.57％ ～3.08％,其中吉林省超重和肥胖检出率均最高,广西壮族自治区最低.结论 中国农村地区学龄前儿童超重/肥胖总检出率较低,3～4岁为农村学龄前儿童超重/肥胖高发期,北部地区超重/肥胖检出率较高,应引起重视.

Objective To analyze the status of overweight and obesity among preschool children in rural areas of ten provinces in China.Methods Using data from ＂Physical development of rural children under the age of 7 from ten provinces of China in 2006＂,preschool children were selected as the object of study.Overweight,mild obesity,moderately obese,severe obesity were defmed as：weight was over 10%,20%,30%,50% than the same sex under height population reference mean.SPSS 13.0 software was used for statistical analysis.x2 test was used to compare rates.Results A total number of 38 923 preschool children were included in the study.The overall prevalence of overweight was 4.18%,with boy＇ s higher than girl＇ s （x2=4.343 6,P=0.037 1） and the highest rate of overweight （5.80%） was seen in the 3-year-old group.The overall prevalence of obesity was 1.21%,with majority as mild （0.78%）.There was no significant difference between boys and girls（x2=0.389 0,P=0.532 8）.The 6 to 7 year old group had the highest rate of obesity （1.42%）.In the ten provinces,the prevalence rates of overweight were 1.38%-7.62% and the obesity were 0.57%-3.08%.The prevalence rates of overweight and obesity showed the highest in Jilin and lowest in Guangxi.Conclusion The overall prevalence rates of overweight and obesity among preschool children in rural areas of China were low,with 3 to 4-year-olds appeared in the age of high incidence of overweight and obesity.The overall prevalence rates of overweight and obesity in northern area were higher than in other areas.
