为了研究导致美国黑人新生儿死亡率较高的一些因素，我们使用了1980年至1981年加州和1979年至1981年格鲁吉亚的匹配队列记录。我们发现，在出生体重和胎龄的任何组合下，体重低于3，000克的黑人新生儿的死亡率都低于白人，但黑人的低出生体重率要高得多，这一生存优势被抵消了。在3,000克或更高的体重下，白人具有生存优势;即使在最佳生存体重下，黑人的死亡率几乎是白人的两倍。如果要降低黑人死亡率，就需要改善黑人出生体重分布和按出生体重划分的死亡率，特别是正常出生体重范围内的死亡率。
To study some of the factors contributing to the higher rate of black neonatal mortality in the United States, we used matched cohort records for California between 1980 and 1981 and for Georgia between 1979 and 1981. We found that at any combination of birth weight and gestational age, black neonates weighing less than 3,000 g had lower mortality rates than whites, but this survival advantage was outweighed by considerably higher rates of low birth weight among blacks. At 3,000 g or more, whites had the survival advantage; even at optimal survival weight, the black mortality rate was nearly twice that for whites. If a reduction in the black mortality rate is to occur, improvements are needed both in the black birth-weight distribution and in birth-weight-specific mortality rates, particularly in the normal birth-weight ranges.
