Estado nutricional y adherencia a la dieta mediterránea en la población escolar de la ciudad de Mataró (Cataluña, España).

Background: there is a decrease in adherence to the Mediterranean diet (MD) and an increase in the prevalence of excess weight among the Spanish child and adolescent population. Objectives: the objective of the present study was to determine the degree of adherence to MD and the nutritional status of the school population of Mataró (Spain) in order to obtain useful information for the design and application of future interventions. Material and Methods: a cross-sectional descriptive study was carried out in a sample of 1177 schoolchildren between 6 and 18 years of age. The KIDMED index was used to assess adherence to MD, and the body mass index (BMI) to assess nutritional status. Questions were related to the students' perception of access to unhealthy foods, availability of money and parental interest in receiving nutrition education. Results: the percentage of children and adolescents with optimal adherence to MD does not reach 50 %, with secondary school youths presenting a lower percentage (30 %). Regarding the nutritional status of the sample, more than 70 % had a normal nutritional status according to their BMI, and 20.7 % of primary school students and 13.8 % of secondary school students were classified as overweight. Conclusions: the data confirm the interest of designing and implementing educational actions involving both students and parents, with the aim of improving the eating habits of the population. The results suggest that availability of money may facilitate access to unhealthy foods and, therefore, the promotion of healthy environments that increase the supply of healthy foods should be considered.
