Regional variations in mortality rates in England and Wales : An analysis using multi-level modelling.
International Symposium in Medical Geography. Vancouver, British Columbia CAN, 1994/07/12.
Mortality rates in England and Wales display a persistent regional pattern indicating generally poorer health in the North and West.
Some of this is simply a reflection of regional differences in the extent of social deprivation which is known to exert a profound influence on health.
Part of the pattern may also be the result of regional differences in urbanization which also affect mortality rates.
However, there may be important regional differences over and above these compositional effects.
This study attempts to establish the magnitude of such independent regional differences in mortality rates by using the techniques of multi-level modelling.
Standardized mortality rates (SMRs) for males and females under 65 for 1989-91 in local authority districts are grouped into categories using the ACORN classification scheme.
The Townsend Index is included as a measure of social deprivation.
Using a cross-classified multi-level model, it is shown that region accounts for approximately four times more variation in SMRs than is explained by the ACORN classification.
Analysis of diagnostic residuals show a clear North-South divide in excess mortality when both regional and socio-economic classification of districts are modelled simultaneously, a possibility allowed for by the use of a multi-level model.
