孕妇妊娠期膳食摄入与体质量增加的相关性研究

摘要

Objective To explore the relationship between maternal diet and weight gain during pregnancy. Methods Totally 767 pregnant women were selected from our hospital,and were divided into 3 groups in accordance with pregnant stage(the early, middle and late stage),then were investigated from pregnancy 12 week to postpartum 5 days. The basic information of pregnant women and weight gain data who were in the cohort were gathered, the intake of the food and dietary nutrient that each pregnant women had eaten in the three stage of their pregnant also were recorded. Results There were significant differences in the daily intake of cereal,meat, oil, total energy, protein, fat, carbohydrates in the three stage of their pregnant (P = 0. 000); The pregnancy gain and the increase of BMI were statistically significant(P = 0. 000). Conclusion The nutrient and dietary pattern of the pregnant women is unreasonable. It should be improved by strengthening nutrition education.%目的 探讨孕妇妊娠期膳食摄入与体质量增加的相关性.方法 以该院767名孕妇为研究对象,进行前瞻性研究,将孕妇按照孕早期、孕中期、孕晚期分成3组,从孕12周开始收集孕妇不同孕周膳食食物消耗量及妊娠期体质量增加资料,追踪至产后5 d.研究膳食结构及营养素摄入对妊娠期体质量增加的影响.结果 妊娠期不同孕周孕妇每人每天摄入谷类、动物肉类、烹调油以及总能量、蛋白质、脂肪、碳水化合物、钙差异有统计学意义(P=0.000);妊娠期体质量增加及BMI增值差异有统计学意义(P=0.000).结论 孕妇膳食结构及其摄入量存在不合理现象,妊娠期营养知识教育亟待加强.
