Abstract
Purpose: The association between egg consumption and cardiovascular events remains controversial. This study aims to evaluate this association in cardiovascular events including myocardial infarction (MI), ischemic coronary heart disease (ICHD), stroke, cardiovascular disease (CVD), and CVD mortality in an Iranian population.Methods: This prospective cohort study included 6504 adults (age ≥ 35 years) with no history of CVD event at baseline. The frequency of egg consumption was assessed using a validated food frequency questionnaire. Participants were followed for 12 years and incidence of new CVD cases were determined through active examinations and linkages to multiple registries. Cox frailty models were conducted to calculate adjusted hazard ratios (HR)s for cardiovascular events associated with egg consumption.Results: Over a median follow-up of 12 years, fully adjusted model [adjusted for age, sex, education, residency, smoking, daily physical activity, family history of CVD, metabolic syndrome, aspirin, body mass index and Global Dietary Index] revealed a null association between egg and cardiovascular events. Compared with non-consumers (<1 time/week), higher egg consumption (≥3 time/week) was not associated with incident MI (HR = 1.44, 95% CI: 0.86, 2.41; P = 0.48), ICHD (HR = 1.26, 95% CI: 0.80, 1.99; P = 0.41), stroke (HR = 0.79, 95% CI: 0.46, 1.38; P = 0.71) and CVD (HR = 1.05, 95% CI: 0.79, 1.40; P = 0.93).Conclusion: These findings suggest that higher egg consumption is not associated with increased risk of MI, ICHD, stroke, and CVD among Iranians. Larger studies with longer duration of follow-up are warranted to explore these associations in populations with higher egg consumption. [ABSTRACT FROM AUTHOR]
