HL Deb 08 July 1986 vol 478 cc271-80WA
Baroness Vickers

asked Her Majesty's Government:

How many cot deaths there were of infants aged under 1 year in England and Wales in 1984 and 1985 in total and for each month of the year.

The Parliamentary Under-Secretary of State, Department of Health and Social Security (Baroness Trumpington)

The table attached shows the number of deaths under 1 year of age with any mention of cot death, sudden infant death syndrome or similar term on the death certificate, irrespective of whether it did or did not appear as the underlying cause of death, for England and Wales by month of occurrence for 1984 and 1985. Figures for 1985 are provisional, due to delays between the death and its subsequent registration while coroners complete their inquiries. Infant deaths which may have been sudden and unexpected, but where no mention of 'sudden' or 'cot' death or similar term was made on the death certificate, cannot be separately identified reliably.

Baroness Vickers

asked Her Majesty's Government:

Whether they will publish the numbers of deaths registered as cot death, sudden infant death syndrome or in similar terms in each health region in England and Wales in total, and subdivided in socio-economic class of the parents and legitimacy for the years 1983, 1984 and 1985; and also the number and percentage of live births in each socio-economic class and illegitimate live births for each region for the same years, 1983, 1984 and 1985.

Baroness Trumpington

The available information for England and Wales is given in the attached tables. These show the number of deaths registered with any mention of 'cot death', 'sudden infant death syndrome' or similar term on the death certificate, irrespective of whether it did nor did not appear as the underlying cause of death, by social class, legitimacy and regional health authority of usual residence of mother for England and Wales for 1983 and 1984. These figures are derived from a procedure which links deaths with the relevant births; the 1985 linked data are not yet available, but figures for regional health authorities only are shown from unlinked data for that year. Figures for cot deaths of all illegitimate babies have been supplied for 1983 and 1984 as these are available from the linked file, but accurate social class information concerning infants of single parents is not collected. Infant deaths which may have been sudden or unexpected, but where no mention of 'sudden' or 'cot' death or similar term was made on the death certificate, cannot reliably be separately identified. Figures for live births are given by social class, legitimacy and regional health authorities for 1983, 1984 and 1985.
