Egg consumption and risk of cardiovascular disease: a PERSIAN cohort-based study

Cardiovascular diseases (CVDs) are one of the main causes of death worldwide. Data on the effect of eggs consumption on the risk of CVDs are still unreliable. Therefore, this study aimed to investigate the association between CVDs and the consumption of eggs.

In this case-control study, the required data were extracted from the Prospective Epidemiologic Research Studies in Iran (PERSIAN) cohort in Sabzevar, Iran. A total of 4241 adults participated including 1535 patients with CVDs as the case group and 2706 healthy people as controls. Egg consumption was assessed using a valid food frequency questionnaire (FFQ).

A significant association was observed between eggs consumption and stroke after adjustment for physical activity, body mass index (BMI), smoking, systolic blood pressure (SBP), diastolic blood pressure (DBP), using alcohol, lipid profile, diabetes, and the intake of energy, lipid, protein, carbohydrate, and cholestrol (OR:1.007, 95% CI:1.001-1.013, P = 0.03). No association was found between egg consumption with hypertension, cardiac ischemia, and myocardial infarction.

There was a significant association between the consumption of eggs and stroke. However, more studies are needed to examine the effect of eggs on CVDs.
