在欧洲国家中，死亡率最低的最佳出生体重因国家而异。我们调查了一个地缘政治群体，美国足月活产婴儿，出生于同一种族父母的五个群体;白色，黑人，西班牙裔，北亚人和南亚人。北亚和南亚人的母亲因素对出生体重更有利。然而，白人的平均出生体重最高，南亚人最低。然而，白人的新生儿死亡率为每1 000例活产0.78例，明显高于北亚人和南亚人的每1 000例活产0.36例和0.72例。其他母亲因素很难解释这种出生体重或死亡率的种族差异。白人的最佳出生体重最高（3，890 g），南亚人最低（3，491 g）。然而，在最佳出生体重的新生儿死亡率显着较低的北亚人。调整母亲的因素，除了父母的种族改变这种差异不大。最佳出生体重及其死亡率因种族而异。在规划人口中的最佳出生结果时，应考虑不同种族的可变死亡风险。
Among European countries, optimal birth weight at which the mortality is minimal is shown to be different by country. We investigated this difference examining one geopolitical population, the U.S. term live births, born to the five groups of the same ethnic parents; White, Black, Hispanic, North Asian, and South Asian. North Asians and South Asians had more favorable maternal factors for birth weight. Yet, Whites had the highest mean birth weight and South Asians, the lowest. However, neonatal mortality rate in Whites was 0.78 per 1,000 live births, significantly higher than 0.36 and 0.72 per 1,000 live births in North Asians and South Asians, respectively. Other maternal factors hardly explained this ethnic disparity in birth weight or mortality. Optimal birth weight was greatest in Whites (3,890 g), and least in South Asians (3,491 g). However, neonatal mortality at optimal birth weight was significantly lower in North Asians. Adjustment of maternal factors except parental ethnicity changed little of this difference. Optimal birth weight and its mortality differ by ethnicity. On planning the best birth outcome in a population, one should consider the variable mortality risks by ethnicity.
