[Evaluation of a nutritional intervention among elderly people: the Edumay project].

Background: The adherence to a Mediterranean Dietary Pattern is associated with a morbi-mortality reduction, and with a better quality of life.

Objectives: To evaluate a nutritional intervention among independent elderly people enrolled in an educational program to increase the knowledge of the food and daily diets, promoting a healthy dietary pattern.

Methods: Quasi-experimental design conducted in elderly participants who lived in foster home apartments owned by the City Council of Pamplona (n = 41). The intervention was based on six group sessions and an individual motivational session in a period of three months. Adherence to Mediterranean diet was evaluated through a 14-point scale previously validated.

Results: Eighty point five per cent of participants were women, with a median age of 79 years, the majority of them widowed (48.8%) and with primary education (58.5%). After the nutritional intervention the percentage of participants who consumed two or more servings of vegetables increased significantly versus the control group (p = 0.042). Similarly, in comparison with the control group, there was an increase in the percentage of participants who consumed three servings per week of legumes (p = 0.042), three or more servings per week of nuts (p = 0.003), and those who consumed preferably meat from chicken, turkey, or rabbit instead of veal, pork, hamburgers, or sausages (p = 0.011).

Discussion: An intervention based on individual and group sessions improved significantly several parameters of a Mediterranean dietary pattern.
