Mediterranean diet adherence in the Mediterranean healthy eating, aging and lifestyle (MEAL) study cohort

A decline in adherence to the Mediterranean dietary pattern has been observed over the last years. The aim of this study was to assess the level of adherence to the Mediterranean diet and possible determinants in the Mediterranean healthy Eating, Aging and Lifestyle (MEAL) study cohort. Demographic and dietary data of 1937 individuals were collected in 2014-2015 from the general population of Catania, Sicily (Italy). Food frequency questionnaires and the MEDI-LITE score were used to assess adherence to the Mediterranean diet. The score well characterised consumption of major food groups, micro- and macro-nutrients. The cohort had a general good adherence, but only a minority was highly adherent. High adherence was directly associated with education, non-smoking and physical activity and inversely with high occupational status. In conclusions, Mediterranean diet is still followed in Sicily; however, nutrition education campaigns should promote healthy traditional dietary patterns in certain groups of individuals.
