孕妇孕期体重增长与饮食营养、体重增长认知程度的相关性分析

Correlation analysis of gestational weight gain and dietary nutrition and the knowledge of weight gain in pregnant women

目的探讨孕妇孕期体重增长与饮食营养和体重增长认知程度之间的关系，为进一步加强孕期的体重和营养管理提供建议。方法根据孕期体重增长情况将100例孕妇分为过低组、正常组和超重组，问卷调查孕妇对孕期饮食和体重增长等相关知识。使用单因素方差分析法比较三组孕妇饮食和增重认知评分之间的差异。结果60％的孕妇体重增长超重，25％的孕妇体重增长正常，15％的孕妇体重增长过低。三组孕妇饮食评分差异有统计学意义（P〈0．01），认知评分差异无统计学意义（P〉0．05）。结论加强孕妇的营养指导，采取有效的监管措施，对孕期体重增长有重要意义。

Objective To explore the relationship of weight gain during pregnancy and dietary nutrition and the knowledge of weight gain, to provide guidance for managing gestational weight and nutrition. Methods 100 pregnant women were investigated with self-designed questionnaire focusing on gestational dietary and weight gain. These pregnant women were divided into three groups according to weight gain during pregnancy-low, normal and high weight gain group. ANOVA was used to explore the difference of dietary nutrition and knowledge of weight gain among the groups. Results Of the 100 pregnant women surveyed, 60% had high weight gain, 25% had normal weight gain and 15% had low weight gain. The dietary scores of the normal and low weight gain group were significantly higher than the high weigh gain group （P 〈0. 01 ）, but the scores of weight gain knowledge had no statistically difference among the groups （P 〉 0. 05 ）. Conclusions It is important to strengthen nutritional guidance and take effective supervision measures on weight gain during pregnancy.
