Longitudinal association of dietary fat intake with cardiovascular events in a prospective cohort study in Eastern Mediterranean region.

ABSTRACT

We examined the association of dietary fats intake with the 13-year risk of cardiovascular disease (CVD) among Iranian population. Totally 5432 participants of Isfahan Cohort Study (ICS) aged ≥ 35 years were included in the current study. The frequency of dietary fats including hydrogenated vegetables oil (HVO), non-hydrogenated vegetables oil (nHVO), olive oil, ghee, and animal fats during the preceding year were assessed using a validated food frequency questionnaire. After adjustment for potential confounders, individuals in the top quartile of HVO tended to have 68% greater risk for myocardial infarction compared with those in the first quartile (95% CI 1.02, 2.78; P = 0.058). No association was found for other dietary fat sources with ischaemic heart disease, stroke, all-cause and CVD mortality after adjustment for all potential confounders. Higher consumption of HVO was associated with increased risk of myocardial infarction.
