This study examines differentials in mean birthweight and the risk for low birthweight among various Asian-American groups in New York State (n = 499,377).
Using resident singleton live-birth records from New York State for 1985 and 1986, Asian-American births were compared with Black, American Indian, and White births. Multivariate ordinary least squares and logistic regression models were used to analyze ethnic differences.
Compared with White births, the expected mean difference in birthweight was -115 g for Chinese, -235 g for Japanese, -164 g for Filipinos, -120 g for Blacks, and 74 g for American Indians. The risk for low birthweight was 45% higher for Filipinos and 49% higher for Blacks as compared with Whites.
Results of this study suggest substantial heterogeneity in mean birthweight and risk for low birthweight among ethnic groups in general and the major Asian-American groups in particular. Interestingly, after controlling for ethnic differences in sociodemographic risk factors, Filipinos appear to resemble Blacks much more closely than they do their Japanese and Chinese counterparts with respect to risk for low birthweight.
本研究调查了纽约州不同亚裔美国人组（n = 499,377）的平均出生体重差异和低出生体重风险。
利用纽约州1985年和1986年的常住单胎活产记录，将亚裔美国人的出生情况与黑人、美洲印第安人和白人的出生情况进行比较。采用多元普通最小二乘法和逻辑回归模型分析种族差异。
与白人出生相比，中国人的出生体重预期平均差异为-115克，日本人为-235克，菲律宾人为-164克，黑人为-120克，美洲印第安人为74克。与白人相比，菲律宾人的低出生体重风险高45%，黑人高49%。
本研究结果表明，总体而言，不同种族之间，尤其是主要的亚裔美国人组之间，平均出生体重和低出生体重风险存在显著差异。有趣的是，在控制了社会人口风险因素的种族差异后，就低出生体重风险而言，菲律宾人似乎与黑人更为相似，而与日本人和中国人的差异较大。
