Background/Objectives: Mediterranean diet has been related with reduced morbidity and better well-being. The aim of this study was to assess whether the adherence to the Mediterranean diet were associated with mental and physical health related to quality of life. Subjects/Methods: This analysis included 11 015 participants with 4 years of follow-up in the SUN Project (a multipurpose cohort study based on university graduates from Spain). A validated 136-item food frequency questionnaire was used to assess the adherence to the Mediterranean diet at baseline, according to a nine-point score, presented in four categories (low, low-moderate, moderate-high and high). Health-related quality of life (HRQL) was measured after 4 years of follow-up with the Spanish version of the SF-36 Health Survey. Generalized Linear Models were fitted to assess adjusted mean scores, the regression coefficients (b) and their 95% confidence intervals (95% CIs) for the SF-36 domains according to categories of adherence to Mediterranean diet. Results: Multivariate-adjusted models revealed a significant direct association between adherence to Mediterranean diet and all the physical and most mental health domains (vitality, social functioning and role emotional). Vitality (b ¼ 0.50, 95% CI ¼ 0.32-0.68) and general health (b ¼ 0.45, 95% CI ¼ 0.26-0.62) showed the highest coefficients. Mean values for physical functioning, role physical, bodily pain, general health and vitality domains were significantly better with increasing adherence to the Mediterranean diet. Those having improved their initial high diet scores have better scores in physical functioning, general health and vitality. Conclusions: Adherence to the Mediterranean diet seems to be a factor importantly associated with a better HRQL.

This communication reports, for the first time, the dependence of the SERS intensities under resonant CT conditions (SERS-CT) on the electrode potential. SERS-CT intensities have been estimated from the properties of S(0)-CT(i) transitions ranging between 200-1200 nm of selected [Ag(n)-pyridine](q) and [Ag(n)-pyrazine](q) complexes.

ObjectiveThe analysis of dietary patterns has become a valuable tool to examine diet-disease relationships but little is known about their effects on quality of life. Our aim was to ascertain the association between major dietary patterns and mental and physical quality of life after 4 years of follow-up.Materials and MethodsThis analysis included 11,128 participants from the “Seguimiento Universidad de Navarra” (SUN) cohort. Dietary habits were assessed using a validated food-frequency questionnaire. Factor analysis was used to derive dietary patterns. Quality of life was measured with the validated Spanish version of the SF-36 Health Survey.ResultsTwo major dietary patterns were identified, the ‘Western’ dietary pattern (rich in red meats, processed pastries and fast-food) and the “Mediterranean” dietary pattern (high in fruits, vegetables and olive oil). After controlling for confounders, the Western dietary pattern was associated with quality of life in all domains. The magnitude of these differences between the subjects in the highest (quintile 5) and the lowest quintile of adherence to the Western pattern ranged from −0.8 (for mental health) to −3.5 (for vitality). On the contrary, the Mediterranean dietary pattern was associated with better quality of life domains: differences ranged from +1.3 (for physical functioning) to +3.4 (for vitality) when comparing extreme quintiles of adherence. Additional sensitivity analyses did not change the reported differences.ConclusionsWhereas baseline adherence to a Western dietary pattern was inversely associated with self-perceived quality of life after 4 years of follow-up, baseline adherence to a Mediterranean dietary pattern was directly associated with better scores in quality of life four years later in the SUN Project.
