[Socioeconomic indicators and mortality for ischemic cardiopathy in the RIFLE population. The RIFLE Group. Risk Factors and Life Expectancy].
The aim of this paper was to evaluate the relationship between socioeconomic indicators (education, occupation and residence) and short-term CHD mortality in an Italian population sample. Socioeconomic indicators and major CHD risk factors (BMI, SBP, DBP, TOT-CH, HDL-CH and TRIG) were measured in 15,315 males aged 40-69 years; mortality data by cause were collected for the next six years. CHD mortality risk ratio (RR) in the different educational and occupational levels and by residence was computed by Cox proportional hazards models. The association between socioeconomic indicators and CHD risk factors was explored by covariance and logistic regression analysis. After six years, 632 men died, 181 of whom because of coronary fatalities. No association with educational level was found for CHD mortality (RR = 1.00 high, 0.69 intermediate, 0.92 low), nor did occupational level show a significant association. Urban vs rural residence (RR = 1.00) showed a RR for CHD mortality of 1.35. Adjustment for bio-behavioral risk factors did not change the above results; only mortality for CHD of urban vs rural residents increased (RR = 1.63, p < 0.003). By considering the interaction between schooling and occupation, it was found that education appropriated to occupational level was a protective factor. The study does not indicate any association between education/occupational level and CHD mortality in male RIFLE population samples. The mean level of major CHD risk factors within different educational/occupational levels supports these results. Status incongruity as well as residence in an urban environment proved to be risk conditions for CHD mortality.
