The purpose of this study was to determine the relative importance of inadequate gestational weight gain as a cause of infant mortality. Birth and infant death certificate data were obtained from a random sample of 100,000 records from the National Center for Health Statistics (NCHS) 2002 Birth Cohort Linked Birth/Infant Death Data File. Descriptive and proportional hazards regression analyses were used to assess the odds of infant mortality associated with inadequate gestational weight gain compared to normal weight gain. Nearly 30% of women experienced inadequate weight gain. Infants born to women with inadequate gestational weight gain had odds of infant death that were 2.23 times the odds for infants born to women with normal weight gain. Increased odds remained after adjustment for gestational age, low birth weight, maternal age, maternal education, and maternal race. Among racial or ethnic subgroups, African American women were 1.3 times as likely as white women to have an infant die, but they were no more likely to have an infant die than white women if they had inadequate weight gain. There is a substantial and significant association between inadequate gestational weight gain and infant death that does not differ by race, ethnic group membership, or maternal age.
这项研究的目的是确定妊娠体重不足作为婴儿死亡原因的相对重要性。本研究从国家卫生统计中心（NCHS）2002 年出生队列链接出生/婴儿死亡数据文件中随机抽取了 100,000 个记录的出生和婴儿死亡证书数据。使用描述性和比例风险回归分析来评估与正常体重增加相比，妊娠体重不足与婴儿死亡相关的几率。近 30%的妇女经历了妊娠体重不足。与体重正常增加的妇女所生婴儿相比，体重不足的妇女所生婴儿的死亡几率高 2.23 倍。在调整了胎龄、低出生体重、母亲年龄、母亲教育和母亲种族等因素后，这种风险仍然存在。在不同种族或族裔亚组中，非裔美国妇女的婴儿死亡几率是白人妇女的 1.3 倍，但如果体重不足，她们的婴儿死亡几率并不高于白人妇女。妊娠体重不足与婴儿死亡之间存在显著且显著的关联，与种族、族裔群体成员或母亲年龄无关。
