目的 了解武汉市洪山区流动儿童生长发育状况,为促进流动儿童体格发育提供科学依据。方法 采用整群抽样方法,选取武汉市洪山区两所小学9~12岁学生,收集752名流动儿童的体质监测资料,对生长发育水平进行分析并与全国体质调研数据进行比较。结果 各年龄组流动儿童身高均低于全国同龄儿童的均值,差异均有统计学意义(P<0.05);男童9岁组、10岁组和女童9岁组的体重均低于相应组别,差异有统计学意义(P<0.05)。消瘦检出率男童高于全国城乡水平,而女童低于全国城乡水平;超重及肥胖检出率男童与全国城市水平接近,女童高于全国城市水平。男童的消瘦、超重及肥胖的检出率与女童相比均较高,11岁年龄组性别差异有统计学意义(P<0.05)。结论 城市流动儿童生长发育水平低于全国城乡儿童均值,流动男童营养不良的状况与女童相比更为严重。

Objective To study growth development status of migrant children in Hongshan district of Wuhan city,and to provide scientific basis for promotion of their physical development. Methods Totally 752 students aged 9~12 from two primary schools in Hongshan district of Wuhan were selected by cluster sampling.Based on monitoring data from migrant children's constitution,analysis of the growth development status and comparision with the national physique survey data were carried out. Results The average height in migrant children was lower than that in national children,and differences on height in each group were statistically significant (P<0.05).The average weight of 9~10 years old boys and 9 years old girls in migrant children were lower than those in corresponding groups,and the differences were statistically significant (P<0.05).The detection rate of emaciation among migrant boys were higher than that in national boys of rural and urban,while the rate among girls were lower.The detection rates of overweight and obesity in migrant boys were close to those in national urban boys,and the rates of girls were higher.Moreover,the detection rates of emaciation,overweight and obesity were higher in migrant boys than those in migrant girls,and the gender differences in 11 aged groups existed (P<0.05). Conclusion The growth development level of urban migrant children is below the average level of national children,and malnutrition situations of migrant boys are more serious than that of migrant girls.
