Abstract
BACKGROUND AND AIMS: Adherence to Mediterranean diet (MD) is reportedly declining in the last decades. We aimed to investigate the adherence to MD over the period 2005-2010 and exploring the possible role of the global economic crisis in accounting for the changing in the dietary habits in Italy. METHODS AND RESULTS: Cross-sectional analysis in a population-based cohort study which randomly recruited 21,001 southern Italian citizens enrolled within the Moli-sani study. Food intake was determined by the Italian EPIC food frequency questionnaire. Adherence to MD was appraised by the Italian Mediterranean Index (IMI). A wealth score was derived to evaluate the economic position and used together with other socioeconomic indicators. Highest prevalence of adherence to MD was observed during the years 2005-2006 (31.3%) while the prevalence dramatically fell down in the years 2007-2010 (18.3%; P<0.0001). The decrease was stronger in the elderly, less affluent groups, and among those living in urban areas. Accordingly, we observed that in 2007-2010 socioeconomic indicators were strongly associated with higher adherence to MD, whereas no association was detected in the years before the economic crisis began; both wealth score and education were major determinants of high adherence to MD with 31% (95%CI: 18-46%) higher adherence to this pattern within the wealthier group compared to the less affluent category. CONCLUSION: Adherence to MD has considerably decreased over the last few years. In 2007-2010 socioeconomic indicators have become major determinants of adherence to MD, a fact likely linked to the economic downturn.
