Abstract
- Objective: The aim of this study was to evaluate adherence to the Mediterranean Diet (MD) and its association with all-cause mortality in an elderly Italian population. Design: Data analysis of a longitudinal study of a representative, age stratified, population sample. Setting: Study data is based upon the Italian Longitudinal Study on Aging (ILSA) a prospective, community-based cohort study. The baseline evaluation was carried out in 1992 and the follow-up in 1996 and 2000. Participant: Participant food intake assessment was available at baseline for 4,232 subjects; information on survival was available for 2,665 at the 2000 follow-up. Measurements: Adherence to the MD was evaluated with an a priori score based on the Mediterranean pyramid components. Cox proportional hazard models were used to assess the relationship between the MD score and all-cause mortality. Six hundred and sixty five subjects had died at the second follow-up (identified up to the first and second follow-up together; mean follow-up: 7.1±2.6 years). Results: At the 2000 follow-up, adjusting for other confounding factors, participants with a high adherence to MD (highest tertile of the MD score distribution) had an all-cause mortality risk that was of 34% lower with respect to the subjects with low adherence (Hazard Ratio=0.66; 95% CI: 0.49-0.90; p=0.0144). Conclusion: According to study results, a higher adherence to the MD was associated with a low all-cause mortality risk in an elderly Italian population. [ABSTRACT FROM AUTHOR]
