The relative effects of sex and deprivation on the risk of early death.

Socio-economic factors and sex are both known to have a pronounced bearing on the risk of early death. To determine the relative effects of these factors in our Health Board, an analysis was carried out of all deaths under the age of 70 registered in Tayside during 1989 and 1990, by age, years of life lost, diagnosis and postcode sector/deprivation category. A yearly average of 14,520 years of life up to the age of 70 were lost by males compared with 8248 by females. When cancers of the breast and sex organs were excluded, just over a quarter (28 per cent) of the difference was due to the higher death rate in males resulting from injuries and poisoning and another quarter to ischaemic heart disease (23 per cent), with infant deaths in third place (17 per cent). Deprivation category analysis showed that deaths and years of lost life from ischaemic heart disease and injuries and poisoning in males in the most deprived areas were approximately one-third higher than in the most affluent. At the same time, the death rate in males from these causes in each area, from the most affluent to the most deprived, was approximately two and a half to three times as high as in females, as were lost years of life.(ABSTRACT TRUNCATED AT 250 WORDS)
