摘要
目的探讨湖北省部分地区孕妇膳食营养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依据。方法抽取湖北省城乡孕妇进行追踪调查,现场完成问卷调查。对孕、产妇和新生儿进行体格检查,采集孕妇血样测定血营养生化指标。结果新生儿302人均为单胎活产,其中男婴156人,女婴146人,性别比为106.85:100,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。
