生殖结果进行了调查，在黑人和白色女性大学毕业生，假定是类似的社会经济地位和类似的风险概况方面的环境因素。数据是通过1988年2月至6月间对格鲁吉亚亚特兰大四所大学的毕业生（1973-1985）进行的邮件调查收集的。在6,867名校友中，有3,084人回复了问卷。一项针对黑人非受访者的后续研究得到了14%（335）没有回复邮件调查的人的回复。对于在调查时有第一个活产的所有毕业生（n = 1，089），早产率、低出生体重率和婴儿死亡率分别为每千名新生儿80.8、82.6和14.6。与白色毕业生相比，黑人毕业生早产风险是白人毕业生的1.67倍，低出生体重风险是白人毕业生的2.48倍。社会和经济地位的衡量标准因种族而异。然而，与白人相比，这些变量的调整并没有降低黑人毕业生的估计风险。对无应答者调查的分析表明，仅应答者数据高估了黑人不良结局的发生率;使用无应答者数据，相对风险1.28（早产）和1.75（低出生体重）被计算为黑人风险增加的下限。
Reproductive outcomes were investigated in black and white female college graduates, presumed to be of similar socioeconomic status and similar risk profile with respect to environmental factors. Data were gathered by mail survey from graduates (1973-1985) of four Atlanta, Georgia, colleges between February and June 1988. Of 6,867 alumnae to whom questionnaires were mailed, 3,084 responded. A follow-up study of black nonrespondents yielded responses from 14% (335) of those who did not respond to the mail survey. For all graduates with a first live born at the time of survey (n = 1,089), the rates of preterm delivery, low birth weight, and infant mortality were 80.8, 82.6, and 14.6 per thousand births (primigravida), respectively. Compared with white graduates, black graduates had 1.67 times the risk of preterm delivery and 2.48 times the risk of low birth weight. Measures of social and economic status differed significantly by race. However, adjustment for these variables did not reduce the estimated risk for black graduates compared with whites. Analysis of the nonresponder survey suggested that respondent data alone overestimates the incidence of adverse outcomes in blacks; using nonresponder data, relative risks of 1.28 (preterm delivery) and 1.75 (low birth weight) were calculated as lower limits of the increased risk for blacks.
