Physical development of suburban children in Guiyang county

目的了解湖南省桂阳县郊区6~7岁儿童生长发育状况。方法采用整群抽样方法,以桂阳县郊区两所小学一年级6~7岁儿童为调查对象,分别测量儿童的体重、身高、坐高、胸围、上臂围等指标。参照2005中国9市现状标准,利用均数标准差法进行生长发育评价,同时对所测数据使用年龄别体重(WAZ)、年龄别身高(HAZ)、身高别体重(WHZ)3种指标进行Z评分法评价。结果桂阳县郊区6~7岁儿童的身高、坐高、体重、胸围低于2005中国9市城郊同龄同性别儿童发育水平,差异有统计学意义(均P<0.05);WAZ、HAZ、WHZ 3项指标均在-1~1者为47.81%,WAZ-1~1为80.88%,-2^-1为9.56%;HAZ-1~1为66.53%,-2^-1为21.51%,<-2为5.98%,1~2为5.98%;WHZ-1~1为72.51%,-2^-1为3.98%,1~2为18.33%,>2、>3分别为2.79%、2.39%。结论桂阳县郊区6~7岁儿童体格生长发育水平低于现状标准,应进一步改进该地区儿童保健服务的水平,改善儿童营养状况,提高生长发育水平。

Objective To understand the status of growth and development of the suburban children in Guiyang coun- ty.
