Alcohol intake is a significant predictor of coronary events. Low-to-moderate intake seems to be associated with a reduction in the prevalence of ACS in diabetes, whereas higher consumption is associated with an increase in lipids and blood pressure levels, and also the risk of developing ACS.
Low vitamin D levels have been associated with several diseases as its receptors are expressed in almost all tissues of the human body. Literature data have shown delayed diabetic foot ulcer (DFU) healing in patients with low vitamin D; however, data on the association between vitamin D levels and DFU in Mediterranean countries are scarce. In this cross-sectional study we examined for differences in serum vitamin D levels between patients with DFU, people with diabetes mellitus (DM) without DFU and healthy individuals in a Southern European country. A total of 96 subjects (33 patients with DFU, 35 patients without DFU and 28 healthy controls) were recruited. Medical and dietary history was obtained and total serum 25-hydroxyvitamin D [25(OH)D] levels were determined. Serum vitamin D levels differed significantly among the three groups of participants; sub-analysis showed that healthy individuals had higher vitamin D levels when compared with patients with and without DFU, while vitamin D levels did not differ between patients with and without DFU (17.9 ± 6.7 vs. 19.8 ± 8.7 ng/mL, P = 0.329, respectively). More than half of patients with DM with or without DFU had vitamin D levels <20 ng/ml. A positive correlation was found between vitamin D and sun exposure duration in participants without DFU. In conclusion, although serum vitamin D levels did not differ between people with and without DFU, the prevalence of deficiency and insufficiency was high in both groups in a Mediterranean country. This finding highlights the need for screening and supplementation with vitamin D in individuals with DM.
BackgroundThere are about 70 small islands in the Aegean and Ionian Sea, of less than 300 Km2 and 5000 inhabitants each, comprising a total population of more than 75,000 individuals with geographical and socioeconomic characteristics of special interest. The objective of the present study was to assess lifestyle characteristics and the state of cardiovascular risk of the population of a small Eastern Mediterranean island, Elafonisos.MethodsPERSEAS (Prospective Evaluation of cardiovascular Risk Surrogates in Elafonisos Area Study) is an ongoing, population-based, longitudinal survey of cardiovascular risk factors, life-style characteristics and related morbidity/mortality performed in a small and relatively isolated island of the Aegean Sea, named Elafonisos. Validated, closed-ended questionnaires for demographic, socio-economic, clinical and lifestyle characteristics were distributed and analyzed. The MedDietScore, a validated Mediterranean diet score was also calculated. In addition, all participants underwent measurement of anthropometric parameters, blood pressure and a full blood panel for glucose and lipids.ResultsThe analysis included 596 individuals who represented 74.5% of the target population. The mean age of the population was 49.5 ± 19.6 years and 48.2% were males. Fifty participants (8.4%) had a history of cardiovascular disease (CVD). The rates of reported diabetes, hypertension, and hypercholesterolemia were 7.7%, 30.9% and 30.9% respectively, with screen-detection of each condition accounting for an additional 4.0%, 12.9%, and 23.3% of cases, respectively. Four hundred and seven individuals (68.3%) were overweight or obese, 25% reported being physically inactive and 36.6% were active smokers. The median MedDietScore was 25 [interquartile range: 6, range 12–47] with higher values significantly associated with older age, better education, increased physical activity, absence of history of diabetes and known history of hypercholesterolemia.ConclusionsObesity and traditional risk factors for CVD are highly prevalent among the inhabitants of a small Mediterranean island. Adherence to the traditional Mediterranean diet in this population is moderate, while physical activity is low. There seems to be a need for lifestyle modification programs in order to reverse the increasing cardiovascular risk trends in rural isolated areas of the Mediterranean basin.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4053-x) contains supplementary material, which is available to authorized users.
Background Over the past decades, the prevalence of obesity has markedly increased worldwide. Stress is recognized as a substantial contributor to increased body weight; therefore, stress management interventions, especially cognitive behavioural, are becoming increasingly popular. The impact of stress management on stress‐ and obesity‐related biomarkers (eg blood lipid profile, HBA1c, inflammatory biomarkers, such as CRP) has been scarcely studied. The aim of this study was to assess the effect of a novel cognitive behavioural stress management intervention, called ‘Pythagorean Self‐Awareness Intervention’ (PSAI), in overweight/obese adults. Materials and methods This was a two‐armed 1:1 randomized, nonblind controlled study including overweight/obese individuals. The control group followed a personalized Mediterranean low‐calorie diet, and the intervention group followed the same diet in addition to the PSAI intervention for 8 weeks. Measurements included demographic, anthropometric (ie BMI, waist‐to‐hip ratio), stress (ie perceived stress, salivary cortisol), dietary behaviour (ie emotional eating) and metabolic parameters (ie blood lipid profile, HBA1c, CRP, body composition in fat and water). Outcome per‐protocol analysis was performed using mixed linear models adjusted for age and gender. Results A total of 49 of 62 eligible adults were analysed in the study (there were three dropouts in the intervention group and 10 dropouts in the control group); 28 were assigned to the intervention group (mean age 54.7 ± 11.9 years) and 21 to the control group (mean age 51.8 ± 11.9 years). The intervention group showed a statistically significant decrease in perceived stress, cortisol concentrations 30 minutes after awakening, cortisol's area under the curve, BMI, waist‐to‐hip ratio, restrained, emotional and external eating behaviour, fasting glucose, LDL, triglycerides, HbA1c and body and trunk fat, compared with the control group. Based on the observed effect sizes, clinically meaningful changes may be more evident in stress perception, restrained and external eating behaviour, Hb1ac and trunk fat. The compliance to the PSAI intervention reached 100%, and there were no adverse effects. Conclusions The PSAI technique may be an effective stress management method for overweight/obese adults. Future and larger randomized controlled studies are needed to allow generalization of these findings.
