摘要
目的：探讨孕期母体体质量增加及人体成分的改变与新生儿出生体质量间的关系。方法：选择来我院建保健卡的单胎健康孕妇70例,分别于孕中期（24-25周）和孕晚期（37-38周）测人体成分,同时监测同期胎儿生长发育状况。结果：共有63例孕妇完成所有的测量项目。孕中期和孕晚期的体质指数（BMI）、蛋白质、无机盐、肌肉量、脂肪量（FM）等与新生儿出生体质量间无相关性（P〉0.05）;孕中期和晚期的基础代谢率（BMR）、细胞内液（ICW）,细胞外液（ECW）,总体水（TBW）,去脂体质（FFM）,体细胞群（BCM）、上臂肌围（AMC）等与母亲体质量的增加有关,且与胎儿出生体质量呈显著相关（P〈0.05）。结论：孕期母体体质量的增加与母亲人体成分的组成和改变有关,并且能影响胎儿的生长发育及出生体质量,FFM是新生儿出生体质量的一个预测因素。
Objective： The purpose of this study was to investigate the relationship among the maternal body composition, gestation weight gain and fetal birth weight. Methods： Pregnant women with a singleton gestation and without medical diseases before pregnancy were enrolled. Anthropometry measurements and bioelectrical impedance measurements were performed during 24 -25 weeks （the second trimester） and 37 -38 weeks（ the third trimester）. Results： Gestation weight gain was correlated significandy with gains of intracellular fluid, extracellular fluid, total body water, body fat , fat free mass, body cell mass, mother＇s basal metabolic rate and arm circumference seperately, which were correlated with the fetal birth weight（ P 〈 0.05 ）. Arm muscle circumference, protein, mineral salt and muscle mass were not correlated with fetal birth weight（ P 〉0.05 ）. Conclusion： Maternal weight gains during pregnancy were affected by their body composition. Fat free mass is considered an important predictor of fetal birth weight.
