    ObjectivesThe purpose of this study was to evaluate the overall diet quality of an Italian population through the use of the Mediterranean Diet Serving Score (MDSS) and its relation to clinical and biochemical nutritional markers.MethodsThe study was conducted on healthy participants ages 18 to 86 y living in central Italy. Adherence to the Mediterranean food pattern was evaluated by a semiquantitative food frequency, using the MDSS. Anthropometric measurements and biochemical analyses of nutritional interest were performed according to the standardized procedure.ResultsThe sample included a total of 349 participants (121 men and 228 women) with an average age of 54 ± 15 y and a body mass index of 27.4 ± 4.8 kg/m2, underlining an overweight status in both men and women. The mean educational level was medium-high in both sexes, whereas the occupation level was higher in women than in men (P = 0.001). The mean MDSS score was 14.4 ± 4.1 out of a total of 24 points. The adherence was higher in women (score 14.7 ± 3.9) than men (score 13.9 ± 4.4), although there were no significant differences (P = 0.25). No statistical differences in MDSS were found in relation to body mass index and educational level, whereas a higher MDSS score was observed in the older age group (P < 0.05). A positive correlation among MDSS, high-density lipoprotein cholesterol, and vitamin C has been found (P < 0.05), whereas there was a negative correlation with uric acid and triacylglycerols (P < 0.05). A logistic regression analysis highlighted smoking habit as the only predictive factor for a high adherence to MDSS (P < 0.05).ConclusionsMDSS has a low adherence to the Mediterranean diet, particularly in the youngest age group and smokers. The index shows a correlation with some parameters of nutritional interest and further larger cohorts studies are needed to confirm our findings.Copyright © 2020 Elsevier Inc. All rights reserved.
