摘要
目的了解阿坝州学龄前儿童生长现状,为改善少数民族地区儿童营养状况提供依据。方法 2015年按整群随机抽样的方法选择阿坝州8个县的城区和乡镇幼儿园,用统一的仪器和方法对4 368名学龄前儿童进行身高、体重、头围和胸围的测量,采用2006年世界卫生组织(WHO)推荐使用的参考标准用Z评分方法,对儿童体格发育及营养状况进行评价。结果在体格测量值方面,大多数年龄组男童的体重、头围、胸围和BMI均大于女童(P<0.05),不同民族在身高、头围、胸围和BMI方面差异均有统计学意义(P<0.05);学龄前儿童的男女童HAZ和女童WAZ总的平均值均为负值。不同民族和不同城乡儿童身高Z评分(HAZ)和体重Z评分(WAZ)差异具有统计学意义(P<0.05)。结论阿坝州学龄前儿童体格发育水平落后于WHO标准,应加强托幼机构儿童保健工作。
