Abstract:   (5350 Views)
Background: Myocardial Infarction (MI) is a main cause of death and disability worldwide, which
involves a number of genetic, physiopathologic and socio-economic determinants. The aim of this
study was to assess the patterns of association between education, wealth and some other risk factors
with non-fatal MI in Tehran population.
Methods: Data derived from a second round of large cross-sectional study, Urban HEART-2, conducted
in Tehran in 2011. Out of 118542 participants, all 249 self-reported incident cases of nonfatal
MI were selected as the case group. A number of 996, matched on age and sex, were selected as
controls. Principle component analysis (PCA) was used to calculate wealth index and logistic regression
model to assess relations between the study variables.
Results: Mean (SD) age of participants was 60.25 (12.26) years. A total of 870 (69.9%) of the
study subjects were men. Education, wealth status, family violence, hypertension and diabetes were
observed as independent predictors of non-fatal MI. Overall, as the level of education increased, the
odds of non-fatal MI decreased (p<0.001). We observed an almost J-shaped association between
wealth status and non-fatal MI. No significant associations were found between marital status, BMI
and current smoking with non-fatal MI (p<0.05).
Conclusion: We found different patterns of association between education and wealth with nonfatal
MI among Tehran adults. Lower risk of non-fatal MI is linked to high educated groups whereas economically
moderate group has the lowest risk of non-fatal MI occurrence
