Abstract Background and Aim: Accumulated evidence supports the effectiveness ofMediterranean-type diets (MeDiet) in reducing mortality and preventing several chronicdiseases. Widely used scores to assess adherence to MeDiet are based on specific sample characteristics;alternatively, they might be built according to absolute/normative cut-off pointsfor the consumption of specific food groups (pre-defined servings/day or/week). The aim ofthis study was to compare sample-specific MeDiet adherence scores (MDS) versus absolutenormativescores (Mediterranean Diet Adherence Screener e MEDAS) on their association withmacronutrient intake, total mortality and incidence of chronic diseases. Design: SUN (SeguimientoUniversidad de Navarra) dynamic prospective cohort study (60.5% women; mean age38.4 years).Methods and Results: In cross-sectional analyses (nZ20,155) we evaluated macronutrientdistribution according to MDS (based on 136-item FFQ), MEDAS (based on 13 questions), andvariants of both. In prospective analyses (nZ9109; mean follow-up: 6.2 years), we evaluateddisease incidence or mortality. Adherence to MeDiet increased with age and, as expected, wasassociated with higher fiber intake, lower total fat intake but higher monounsaturated/saturatedfat ratio, using all scores. Among subjects initially free of cancer, diabetes, and cardiovasculardisease (CVD), adherence to MeDiet appraised with an absolute-normative score(MEDAS) similarly predicted macronutrient distribution and disease incidence or mortality (diabetes incidence, CVD or all-cause mortality), when compared to a sample-specific scorebased on 136-item FFQ (MDS).Conclusions: Adherence to MeDiet was associated with a decreased incidence of a compositeoutcome including diabetes incidence, cardiovascular events incidence or all-cause mortality.
