| Summary: | Introduction & Aim: The prevalence of diabetes is
increasing at an alarming rate in nearly all countries.
Some studies from non-Mediterranean populations
suggest that higher egg consumption is associated with an
increased risk of diabetes. The aim of our study was to
prospectively assess the association between egg
consumption and the incidence of type 2 diabetes in a
large cohort of Spanish university graduates.
Methods: In this prospective cohort including 15,956
participants (mean age: 38.5 years) during 6.6 years
(median), free of diabetes mellitus at baseline. Egg
consumption was assessed at baseline through a semiquantitative food-frequency questionnaire repeatedly
validated in Spain. Incident diabetes mellitus diagnosed
by a doctor was assessed through biennial follow-up questionnaires and confirmed subsequently by medical
reports or records, according to the American Diabetes
Association criteria. Analyses were performed through
multivariable non-conditional logistic regression.
Results: After adjustment for confounders, egg
consumption was not associated with the development of
diabetes mellitus, comparing the highest versus the lowest
quartile of egg consumption (>4 eggs/week vs<1 egg/week):
odds ratio= 0.7; 95% CI 0.3-1.7.
Conclusion: Egg consumption was not associated with
the development of diabetes mellitus in this Mediterranean cohort.
