母亲营养状况对子女早期生长发育影响的研究

目的研究母亲营养状况对其所生子女生长发育状况及其健康的影响。方法利用2002年中国居民营养与健康状况调查的数据，以调查中18～44岁女性身高均值156．4cm为参考值，对1380名母亲及其所生2岁子女的相关资料进行分析。结果2岁子女身高与母亲身高有显著正相关性（P〈0.0001），与身高≥156.4cm母亲所生子女身高相比，身高〈156．4cm的母亲所生2岁子女身高平均低2．4cm；2岁时的生长迟缓率是身高≥156cm母亲所生子女的2，07倍，即2岁子女生长迟缓的危险性随母亲身高的增加而降低。结论母亲营养状况影响其子女的生长发育，改善女性营养是保证下一代生长发育的关键因素之一。

The influence of maternal nutrition on children physical development

Objective To study the effect of maternal nutrition status on child growth in China. Methods The study was performed using data from 2002 China Nutrition Health Survey in which data were collected through stratified multi-stage cluster samples in 31 provinces, autonomous regions, and municipalities. Accroding to the height of women aged 18-44 y was 156.4 cm, the data on mother and children' weight and height/length (n= 1380) were analyzed. Results The findings suggest child's length (age 2) were significantly correlated with maternal heights (P<0.0001). The mean length in children born to mothers with a height below 156.4 cm was 2.4 cm less than those in children born to mothers with a height above 156.4 cm. The prevalence of stunting in children at age 2 born to mothers with a height below 156 cm was 2.07 times of that in children born to mothers with a height above 156 cm. Therefore, the risk for stunting in children at 2 is lower in children born to mothers with greater height. Conclusion The maternal nutrition status could have a significant influence on children physical development.
