摘要
目的探讨湖北省部分地区孕妇膳食营养等因素对新生儿出生体重的影响,为制定符合湖北省实际情况的干预策略和措施提供参考。方法抽取湖北省城乡孕妇进行追踪调查,对孕、产妇和新生儿进行体格测量,采集孕妇血样测定血营养生化指标,现场完成问卷调查并对结果进行处理。结果新生儿平均出生体重为3392g,低出生体重儿和巨大儿发生率分别为3.97%和13.25%。孕期增重较少、血清钙和血清维生素A浓度较低是孕妇分娩低出生体重儿的危险因素。孕期增重过多、孕前体质指数(BMI)过高是孕妇分娩巨大儿的危险因素。结论孕妇膳食、营养影响新生儿出生体重,保持合理的孕前体质指数、适当的孕期增重、提高血钙水平、维持孕期正常范围的维生素A浓度有助于分娩适宜体重的新生儿。

Anthropometric measurements of newborns and pregnant women were taken, blood samples of pregnant women were obtained for nutritional analyses, and made by ourselves were finished. All data were analyzed by t test, Fisher test, correlation analysis, and multiple regression analysis. Results The mean birthweitht of newborns was 3392g.The proportion of low birth weight and macrosomia was 3.97% and 13.25%, respectively. Pregnancy less weight gain and serum calcium and vitamin A lower concentration increased the risk in pregnant women birthing LBW. Effects on macrosomia were pregnancy more weight gain and higher BMI before pregnancy. Conclusions Dietary and nutritional status of pregnant women affected newborn birthweight. Keeping good BMI before pregnancy, pregnancy proper weight gain, increasing serum calcium concentration, and maintaining normal serum vitamin A concentration attributed to delivery of normal weight newborn.
