| 目的 探讨宁波市7岁以下儿童年龄别身高、体重、BMI变化特点及体格发育现状和规律。方法 随机整群抽样调查64 038名健康儿童的身高、体重,按年龄别性别计算身高、体重、BMI的均值、标准差和百分位数,与WHO(2006年)和中国9市城区(2005年)调查结果的参照标准进行比较。结果 男女儿童体重、身高的年增长速度基本一致,各项指标随年龄增加而增长,年龄越小增长速度越快,且存在性别和城乡差异。儿童BMI随年龄和性别不同有明显变化,4～6个月时达高峰,以后随年龄增加而缓慢下降。结论宁波市7岁以下儿童身高、体重平均生长水平已达到甚至超过WHO标准,儿童体重、身高的年增长速度与2005年中国9市城区调查的同年龄人群平均水平总趋势一致。 |
