摘　　要：目的探讨孕妇孕前身体质量指数、孕期体重增重、脂肪分布与新生儿出生体重之间的关系，为进一步加强孕期营养指导工作提供建议。方法问卷调查108名孕妇的基本情况，监测孕妇孕期体重增长情况，计算孕前身体质量指数、孕中期体重增幅及脂肪分布，并记录新生儿的出生体重。结果72％的孕妇孕前营养状况正常，但孕中期73％的孕妇体重增加超过了适宜增重标准的60％，脂肪分布〉140g／cm（肥胖）者占46％，孕中期脂肪分布与孕前身体质量指数呈正相关（rs=0．368，P〈0．001）。在已分娩的59名新生儿中，平均出生体重为3272．7±398．6g，有6人的出生体重≥4000g，新生儿出生体重与孕中期脂肪分布呈负相关（rs=-0．727，P〈0．001）。结论孕妇在孕中期体重增长过多，巨大儿发生比例较高，因此加强孕期的营养指导，合理膳食对母亲及其新生儿出生体重具有重要意义。Objective To explore relationships of pregestational body mass index （BMI）, weight gain during pregnancy, body fat distribution with birth weight of the newborn, so as to provide a guidance for gestational nutrition. Methods 108 pregnant women were investigated with a self-designed questionnaire for their general information. Pregestational BMI of the pregnant woman was calculated according to data investigated. Weight gains during whole pregnancy and in the second trimester of gestation of the pregnant woman and her body fat distribution were monitored. The birth weight of the neonate was measured and recorded. Results 72% of pregnant women had a normal pregestational nutritional status. While the weight gain of 73% of pregnant women exceeded by 60% of the proper standard of weight gain by end of the second trimester of gestation and body fat distribution of 46% of pregnant women was over 140g/cm（obesity）. There was a positive correlation between body fat distribution in the second trimester of gestation and pregestational BMI （ rs = 0.368, P 〈 0. 001 ）. Among 59 neonates, the average birth weight was 3 272.7 ± 398.6g, of which, the birth weight of 6 of them was ≥ 4 000g. Birth weight of the neonate was negatively correlated to body fat distribution of the pregnant woman in the second trimester of gestation（ rs = - 0.727, P 〈 0.001 ）. Conclusion If the weight gain of the pregnant woman in the second trimester of gestation is excessive, the incidence of macrosomia is higher. It is important to strengthen gestational nutritional guidance for pregnant women and supply them proper diet for maternal health and normal birth weight of the neonate.
