To compare the relation of birth weight with socioeconomic status measured by an area-based measure of material deprivation and by the Registrar General's social class.
Study design-Retrospective cohort study.
Method-Birthweight data by enumeration district deciles ranked by Townsend Deprivation Index based on 1991 census data for all live births in the West Midlands Health Region were studied in three consecutive whole year birth cohorts, 1991 to 1993 and by Registrar General's social class in a 10% sample of live births (within marriage and jointly registered, provided by the Office of National Statistics) in the same region for the same period.
Estimated proportions of births<2500 g and<3500 g « attributable » to social inequalities were compared for both socioeconomic status measures.
The proportion of infants in each birthweight group were calculated for both measures.
Relative risk (95% confidence intervals) of birth in each birthweight group for lowest versus highest socioeconomic status groups were calculated.
The estimated proportions of births<2500 g « attributable » to social inequalities were 30% using the area-based measure and 27% using the Registrar General's social class.
For births<3500 g, the estimated proportions were 12% for the area-based measure and 7% for social class. (...)
