title: Relation of maternal ethnicity to infant birthweight in east London, England.
abstract: OBJECTIVE
  We sought to determine whether black race is a risk factor for very low birthweight in a developed country other than the United States.
  
  
  METHODS
  A cross-sectional study was performed.
  
  
  METHODS
  We analyzed a dataset of 1987-1990 birth records from three hospitals in East London, England.
  
  
  METHODS
  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.
  
  
  METHODS
  For each ethnic group, we calculated the proportion of very low birthweight (< 1500g) and moderately low birthweight (1500-2499g) infants.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  We conclude that black race is a risk factor for very low birthweight in the United Kingdom.
