[Inequalities in mortality in Seville [Spain]]

Abstract

Objectives: To describe social inequalities in mortality in Seville from 1994 to 1998 according to socioeconomic status.

Methods: Life expectancy, crude and age-adjusted rates of total mortality as well as mortality by causes and potential years of life lost were estimated using the number of deaths and the population of Seville, aggregated by Basic Health Areas (BHA). BHA were divided in three levels according to the unemployment rate among men. The relative risks of total mortality and mortality by causes were estimated for men and women in each of these levels, using Poisson regression. The unemployment rate of each of the BHA was related to total mortality and to some of its causes.

Results: Differences in life expectancy of up to 7.9 years for men and 4.6 years for women were found among BHA. Concerning potential years of life lost, the areas with the highest mortality showed 4.1 times greater mortality in men and 2.6 times greater mortality in women than those with the lowest mortality. Total mortality increased with unemployment rate: the BHA with the highest unemployment rate showed a 15% increase in mortality in men and a 6% increase in that in women than those with the lowest unemployment rate. Among causes of mortality, AIDS showed the greatest inequalities in both men and women.

Conclusions: From 1994 to 1998, Seville presented inequalities in total mortality and premature mortality, as well as in mortality by causes per BHA. Inequalities were present in men and women, although they were greater in men. There was a clear association between socioeconomic variables and mortality.
