RESUMEN
Perinatal and postneonatal mortality among immigrants to England and Wales from India, Pakistan and Bangladesh (Asians) for the years 1982-85 showed significant differences not only between the immigrant and indigenous populations, but also among the different groups from the Indian subcontinent. Compared with the perinatal mortality rate of 10.1 per 1000 total births in UK born mothers, rates in infants of mothers born in India, Bangladesh, and Pakistan were 12.5, 14.3 and 18.8 respectively. In contrast, postneonatal mortality in infants of Indian and Bangladeshi origin (3.9 and 2.8 per 1000 live births respectively) was lower than in the indigenous population (4.1), with Pakistani infants experiencing the highest rate (6.4). Excess perinatal mortality in infants of Asian origin was apparent at most maternal ages and parities. Pakistani infants had the highest rates of perinatal and postneonatal mortality in all age, parity and birth weight groups. The Asian groups showed higher mortality from congenital anomalies in both the perinatal and the postneonatal period, the rates in Pakistani infants being almost double those in Indian and Bangladeshi infants. A significant finding was the lower rates of sudden infant death in all the groups of Asian origin.
