Long-term fish intake is associated with better lipid profile, arterial blood pressure, and blood glucose levels in elderly people from Mediterranean islands (MEDIS epidemiological study).

Background: A study to evaluate the link between long-term fish intake and health status in a sample of elderly adults was undertaken.

Material/methods: Three hundred men and women from Cyprus, 142 from Mitilini, and 100 from Samothraki islands (aged 65 to 100 years) were enrolled in this study during 2005-2006. Dietary habits (including fish consumption) were assessed through a food frequency questionnaire.
