种族、家庭收入和低出生体重之间的关系是使用从国家青年纵向调查中获得的信息来检验的，该调查每年对20世纪70年代末确定的具有全国代表性的年轻女性样本进行采访。这些妇女及其后代从1979年到1988年的数据是可用的。在横断面和纵向分析中，母亲受教育程度、母亲年龄、年龄/胎次风险、婚姻状况和怀孕期间吸烟作为协变量。无论贫穷是在研究开始前还是在研究期间确定的，贫穷的黑人妇女和贫穷的白人妇女的出生体重低的风险都处于相似的高水平。纵向分析显示，前一次怀孕生下低出生体重婴儿的妇女所生的孩子低出生体重的风险异常大。这两个发现强调了怀孕前因素对低出生体重的重要性。
The relations among race, family income, and low birth weight were examined using information obtained from the National Longitudinal Survey of Youth, which conducted yearly interviews with a nationally representative sample of young women identified in the late 1970s. Data were available for these women and their offspring from 1979 through 1988. Maternal education, maternal age, age/parity risk, marital status, and smoking during pregnancy served as covariates in cross-sectional and longitudinal analyses. The risk of low birth weight among births to black women and white women who were poor was at similarly high levels regardless of whether poverty was determined prior to study entrance or during the study period. Longitudinal analyses showed an exceptionally large increase in risk of low birth weight among children born to women whose prior pregnancy ended in a low-birth-weight infant. These two findings emphasize the importance of factors antecedent to the pregnancy in the genesis of low birth weight.
