Association between Mediterranean lifestyle and perception of well-being and distress in a sample population of university Italian students

We investigated the extent to which adherence to the Mediterranean diet (MD) in combination with Mediterranean lifestyle factors influenced students’ perceptions of subjective well-being (SWB) and distress. 939 undergraduates completed a survey to assess sociodemographic and lifestyle characteristics, including adherence to the MD, depression, anxiety, stress, and SWB. Data were analysed with correlation, logistic, and multiple linear regression models. Higher adherence to MD correlated with better SWB. Fruit, red meat, sweet and caffeinated beverages contributed significantly. However, it was the combination of adherence to MD with other factors, including quality of social relationships, income, smoking, sleep, and physical activity that better predicted SWB. Our results confirm the positive influence of MD on SWB. However, they also suggest the need to consider perceptions of well-being by a more holistic approach that considers physical and social factors simultaneously to improve the development of more effective educational and motivational programmes.info:eu-repo/semantics/publishedVersio

Effect of cocoa products and its polyphenolic constituents on exercise performance and exercise-induced muscle damage and inflammation: A review of clinical trials

In recent years, the consumption of chocolate and, in particular, dark chocolate has been “rehabilitated” due to its high content of cocoa antioxidant polyphenols. Although it is recognized that regular exercise improves energy metabolism and muscle performance, excessive or unaccustomed exercise may induce cell damage and impair muscle function by triggering oxidative stress and tissue inflammation. The aim of this review was to revise the available data from literature on the effects of cocoa polyphenols on exercise-associated tissue damage and impairment of exercise performance. To this aim, PubMed and Web of Science databases were searched with the following keywords: “intervention studies”, “cocoa polyphenols”, “exercise training”, “inflammation”, “oxidative stress”, and “exercise performance”. We selected thirteen randomized clinical trials on cocoa ingestion that involved a total of 200 well-trained athletes. The retrieved data indicate that acute, sub-chronic, and chronic cocoa polyphenol intake may reduce exercise-induced oxidative stress but not inflammation, while mixed results are observed in terms of exercise performance and recovery. The interpretation of available results on the anti-oxidative and anti-inflammatory activities of cocoa polyphenols remains questionable, likely due to the variety of physiological networks involved. Further experimental studies are mandatory to clarify the role of cocoa polyphenol supplementation in exercise-mediated inflammation. © 2019 by the authors. Licensee MDPI, Basel, Switzerland

Physical activity habits prevent psychological distress in female academic students: The multiple mediating role of physical and psychosocial parameters

Background: Psychological distress is recognised as the most common mental health difficulty in emerging adult (18-to-24-year-old) female academic students. This study aimed to test a novel model positing physical activity habits as a protective factor for psychological distress through the mediating role of physical and psychological parameters. Adherence to the Mediterranean diet and self-reported physical health status were included as physical parameters. Self-reported psychological health status and time spent on leisure activities were the psychological parameters considered. Method: Data were collected between April and May 2021. Correlation analyses and a multiple mediation model were computed on 411 online questionnaires filled out by 18-to-24-year-old female students from the University of blind (Italy). Results: The multiple indirect effects were significant (β = −0.088; p < 0.001). This means that physical activity habits reduce psychological distress through high adherence to the Mediterranean diet, a good self-assessment of one's physical and psychological health status, and more time spent on leisure activities outdoors, with friends, and with family members. Conclusions: Results show that academic policies should be adopted so as to design physical activity programmes that may improve the students’ healthy behaviours and social interactions, which, in turn, mitigate the detrimental effects of psychological distress

Vitamin D levels in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL)

Besides its well known function on bone metabolism, vitamin D role in cerebrovascular pathologies including cerebral small vessel disease has been confirmed by recent meta-analysis. In this study, we measured vitamin D levels in 56 Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) patients (mean age 49.9) with no or minimal disability (modified Ranking Score, mRS 642) and in 56 age, sex and seasonality matched healthy controls. History of ischemic events was recorded and cognitive functions were assessed using the Mini-Mental State Examination. White matter hyperintensities on brain T2-weighted magnetic resonance images were classified according to a modified Fazekas scale. Comparison of vitamin D levels between patients and controls showed significant lower values (p < 0.05) in no-to-mild CADASIL patients and a higher number of subjects with severe deficiency [25(OH)D <10 ng/ml]. Vitamin D levels did not correlate with vascular risk factors, clinical data or Fazekas score. The role of vitamin D is worth to be further explored in prospective studies
