【摘要】：目的:探讨孕妇分娩年龄对妊娠期体重增长及新生儿出生体重的影响。方法:收集于哈尔滨医科大学附属第四医院产科产检并分娩的1563例孕妇,记录其年龄、身高、孕前体重、妊娠期体重增长、新生儿出生体重。根据2009年美国医学研究所(IOM)公布的妊娠期体重增长推荐值,按孕前BMI分为4组:18.5kg/m~2(293例),18.5~24.9kg/m~2(1060例),25~29.9kg/m~2(177例),≥30kg/m~2(33例);再根据妊娠期体重增长值,将每组细分为体重增长不足、增长适宜、增长过多3个亚组。结果:(1)孕前BMI值越大,妊娠期体重增长超过推荐值的发生率越大(r=0.120,P=0.000)。(2)妊娠期体重增长值随着分娩年龄(B=-0.073,P=0.004)及孕前BMI(B=-0.200,P=0.000)的增加而减少。(3)新生儿出生体重随着分娩年龄(B=0.068,P=0.016)及妊娠期体重增长(B=0.188,P=0.00)的增加而增加。结论:选择适当的年龄妊娠,合理控制孕前体重及妊娠期体重增长,有利于获得良好的母儿结局。
[Abstract]:Objective: to investigate the effect of delivery age on gestational weight gain and neonatal birth weight. Methods: 1563 pregnant women were collected from the fourth affiliated Hospital of Harbin Medical University. Their age, height, weight before pregnancy, weight gain during pregnancy and birth weight of newborn were recorded. According to the recommended value of gestational weight gain published by the American Institute of Medicine (IOM) in 2009, BMI was divided into four groups according to pre-pregnancy BMI: 18.5 kg / m-2 (293 cases), 18.5 kg / m-2 (1060 cases), 255kg / m-2 (177 cases), 鈮，
