孕妇身体质量指数与新生儿出生体重的关系

摘要

目的 探讨孕妇身体质量指数对新生儿出生体重的影响.方法 选择符合纳入标准的妊娠期妇女90例为研究对象.测量孕妇临产时身体质量指数、血糖、新生儿出生体重等指标,分析其间的关系.结果 90例孕妇的血糖水平为5.3±1.2 mmol/L、年龄为26.2±6.0岁、身体质量指数为23.8±3.9 kg/m2,新生儿出生体重为3 425.4±1 433.0g.新生儿出生体重与孕妇身体质量指数、年龄成正相关(身体质量指数偏相关系数:r=0.817,P=0.000;年龄偏相关系数:r=0.228,P=0.033),且孕妇身体质量指数与新生儿出生体重呈线性关系.结论 孕妇身体质量指数与新生儿出生体重存在正相关关系,检测孕妇身体质量指数对新生儿出生体重有一定的预测价值.%Objective To investigate effect of maternal body mass index (BMI) during pregnancy on birth weight of the neonate. Methods 90 pregnant women were included in this study. Age, BMI and blood glucose at parturition of the pregnant women and birth weight of their neonates were measured and detected, and correlation between maternal body mass index in parturition and birth weight of the neonate was analyzed. Results The mean blood glucose level of 90 pregnant women was 5.3 ± 1.2 mmol/L, their mean age was 26.2 ± 6.0 years, their BMI at parturition was 23.8 ± 3.9 kg/m2 , and mean birth weight of their neonates was 3 425.4 ± 1 433. 0g. There were positive correlations between birth weight of the neonates and maternal BMI or maternal age (r =0. 817, P =0. 000 and r =0. 228, P =0.033,respectively). Even there existed a linear correlation between maternal BMI at parturition and birth weight of the neonate ( y = 302.6, x =-3 775.0). Conclusion There is positive correlation between maternal BMI and birth weight of the neonate. Measurement of maternal BMI at parturition has some clinic values in predicting birth weight of the neonate.
