目的 了解义乌市城区学龄儿童身高、体重状况,探讨当地学龄儿童超重、肥胖和矮小的发病情况,为开展儿童早期干预研究提供线索。方法 抽取义乌市城区学龄儿童共2 069名,测量身高、体重,并计算出体质指数(BMI),以2005年九省市儿童体格发育调查数据的标准,计算超重、肥胖、矮小的检出率,并分析特点。结果 1)男、女生6.0~6.5岁、8.0~11.5岁组身高、体重均高于全国水平。2)超重和肥胖的总检出率为10.68%和14.16%,男生(11.27%和14.77%),女生(9.91%和13.36%)。3)矮小的总检出率为2.80%,男生和女生为2.73%和 2.90%。结论 超重和肥胖的检出率较高,矮小的发病率稍低于全国水平,超重和肥胖问题颇为严重,矮小问题也不容忽视,都需要及时有效干预。

Objective To understand the status of height and weight of urban school-age children in Yiwu,investigate the incidence of overweight,obesity and short stature,and to provide the clues for early intervention of children. Methods Totally 2 069 school-age children were selected from urban area of Yiwu city.Data of height and weight were collected and body mass index was calculated.Using the survey data of children's physical development in nine provinces and municipalities in 2005 as a standard,the prevalences of overweight,obesity and short stature were calculated and analyzed. Results 1) The height and weight levels of boys and girls in 6.0~6.5 and 8~11.5 groups were all higher than the national levels.2)The prevalence of overweight and obesity was 10.68% and 14.16% respectively (11.27% and 14.77% for boys,9.91% and 13.36% for girls).3)The total prevalence of short stature was 2.80%( 2.73% for boys and 2.90% for girls). Conclusions The prevalence of obesity is high.The prevalence of short stature is lower than the national level.The situation of childhood overweight and obesity becomes more serious,and the short stature problem can not be ignored,they all deserve timely and effective interventions.
