Abstract

A Mediterranean dietary pattern has been associated with reducing the risk of cardiovascular and chronic disease. The aim of this study was to evaluate the role of nutrition knowledge in determining possible differences among dietary patterns in a general population from a Mediterranean region. We conducted a cross-sectional study on a subsample of 744 subjects enrolled in the population-based cohort of the Moli-sani Project. A 92-item questionnaire on nutrition knowledge was elaborated, validated and administered. Dietary information were obtained from the EPIC food frequency questionnaire and adherence to a Mediterranean dietary pattern was evaluated both by the a priori Greek Mediterranean diet score and the a posteriori approach obtained by principal component analysis. Nutrition knowledge was significantly associated with higher adherence to a Mediterranean dietary pattern. The odds of having higher adherence to a Mediterranean dietary pattern increased with greater nutrition knowledge. The odds ratio of being obese significantly decreased with increasing nutrition knowledge levels. The results showed that nutrition knowledge was significantly associated with higher adherence to a Mediterranean dietary pattern and with lower prevalence of obesity in a Southern Italian region with Mediterranean diet tradition independently from education and other socioeconomic factors.
