We sought to determine whether black race is a risk factor for very low birthweight in a developed country other than the United States.
A cross-sectional study was performed.
We analyzed a dataset of 1987-1990 birth records from three hospitals in East London, England.
All live born African (N = 3,495), West Indian (N = 3,471), and European white (N = 20,313) singleton infants born to East London residents.
For each ethnic group, we calculated the proportion of very low birthweight (< 1500g) and moderately low birthweight (1500-2499g) infants.
The very low birthweight rate was 2.9% for infants of West Indian descent and 2.2% for infants of African descent vs. 1.3% for European whites; odds ratio (95% confidence interval) = 2.1(1.7-2.8) and 1.8(1.2-3.1), respectively. West Indian and white mothers were similar in terms of age, social support, and prenatal care. African mothers were older and had less social support. The West Indian:white and African:white differentials in very low birthweight rates persisted among low risk mothers; odds ratio (95% confidence interval) = 2.7(1.7-4.0) and 2.3(1.5-3.6), respectively.
We conclude that black race is a risk factor for very low birthweight in the United Kingdom.
我们试图确定在除美国以外的发达国家中，黑人种族是否是极低出生体重的一个风险因素。
进行了一项横断面研究。
我们分析了来自英国东伦敦三家医院的1987 - 1990年出生记录数据集。
所有在东伦敦居住的非洲裔（N = 3495）、西印度裔（N = 3471）和欧洲白人（N = 20313）单胎活产婴儿。
对于每个种族群体，我们计算了极低出生体重（<1500克）和中度低出生体重（1500 - 2499克）婴儿的比例。
西印度裔婴儿的极低出生体重率为2.9%，非洲裔婴儿为2.2%，而欧洲白人婴儿为1.3%；优势比（95%置信区间）分别为2.1（1.7 - 2.8）和1.8（1.2 - 3.1）。西印度裔和白人母亲在年龄、社会支持和产前护理方面相似。非洲母亲年龄较大且社会支持较少。在低风险母亲中，西印度裔与白人、非洲裔与白人在极低出生体重率上的差异仍然存在；优势比（95%置信区间）分别为2.7（1.7 - 4.0）和2.3（1.5 - 3.6）。
我们得出结论，在英国，黑人种族是极低出生体重的一个风险因素。
