Narrowing social inequalities in health ? Analysis of trends in mortality among babies of lone mothers.
Objectives To examine trends in mortality among babies registered solely by their mother (lone mothers) and to compare these with trends in infant mortality for couple registrations overall and couple registrations subdivided by social class of father.
Design Analysis of trends in infant death rates from 1975 to 1996 for the three groups.
The data source was the national linked infant mortality file, containing all records of infant death in England and Wales linked to the respective birth records.
Setting England and Wales.
Participants All live births (n=14.3 million) from 1975 to 1996 ; all deaths of infants from birth to 12 months of age over the same period (n=135 800).
Main outcome measures Death rates in the perinatal, neonatal, and postneonatal periods and for infancy overall.
Results For the babies of lone mothers infant mortality has fallen to less than a third of the 1975 level, with a clear reduction in the gap between the mortality in these babies compared with all couple registrations : the excess mortality in solely registered births was 79% in 1975 reducing to 33% in 1996.
Most of the narrowing of the sole-couple differential was associated with the neonatal period, for which there is now no appreciable gap.
For couple registrations analysed by social class of father, infant death rates have more than halved in each social class from 1975 to 1996.
The reductions in mortality were greater in the late 1970s and early 1990s. (...)
