天津市城乡46 357名7岁以下儿童体格发育调查

【目的】了解天津市城乡7岁以下儿童体格生长现状和变化趋势。【方法】采取随机整群抽样的方法，分城、乡，男、女各22个年龄组，对7岁以下儿童进行体重、身高、坐高、胸围、头围、上臂围六个体格生长指标的测量，及与儿童生长发育相关资料的调查。【结果】共调查天津市城乡儿童46357人，男童的体格生长指标好于女童，城市儿童好于农村儿童，差异有显著性（P〈0．01）。天津市城区儿童体格发育指标的均值较1995年天津市儿意体格发育调查结果增高，总体水平高于国内、国际参考标准。【结论】身高、体重作为评价儿童生长发育的重要指标。体重的增长幅度大于身高，以及胸廓的大增长幅度可能是肥胖儿童增加的一种表现。上臂围的测量结果反映丁随年龄增长而增长的趋势，能否作为大人群儿童的常规测量项目值得探讨。
