Objectives. This work aims at exploring the association between fish intake and depressive symptoms, in older adults. Method. During 2005-2007, 1,190 men and women (>65 years) free living in various Greek islands and in Cyprus participated in the study. Depressive symptoms were assessed using the validated Geriatric Depression Scale (GDS), and foods intake through a Food Frequency Questionnaire. Results. Almost 70% of the participants scored above the depressive cutoff (i.e., GDS score > 5), with women having higher values. People classified under the 1st tertile of GDS score (i.e., GDS

Abstract Dietary fats have long been associated with human health, and especially cardiovascular disease (CVD). Some observational studies have shown that reduction in dietary fats, and particularly cholesterol is associated with lower cardiovascular risk; however, other prospective studies or randomized controlled trials of dietary fat reduction or modification have shown varying results on CVD morbidity and mortality. In this work we evaluated the relationships between dietary fats and a cluster of CVD risk factors (i.e., diabetes, obesity, hypercholesterolemia, hypertension), among elderly individuals without known CVD. In particular, dietary and clinical data from 1486 elderly (aged 65 to 100 years) men and women living in Cyprus, Mitilini, Samothraki, Cephalonia, Crete, Lemnos, Syros, Naxos, Corfu and Zakynthos islands, and participated in the MEDIS study, were analysed. Data analysis revealed that 18.5% of males and 33.3% of females had three or four cardiovascular disease risk factors; the major source of fat was olive oil (mean intake for men and women 50.0 ± 19.3 g/day and 46.0 ± 16.8 g/day, p < 0.001). In addition it was observed that a 5% increase in energy adjusted fat intake from meat was associated with a 21% increase in the likelihood of having one additional CVD risk factor (95%CI 6%-39%); no significant associations were observed regarding the other types of fat consumed by the elderly participants. These findings may state a hypothesis that the consumption of fat only from meat or its products seems to increase the burden of CVD risk factors among CVD-free, elderly people.

Abstract Background Hypercholesterolemia is one of the most important factors causing cardiovascular disease (CVD). The aim of the present work was to evaluate the relationships between socio-demographic, clinical, lifestyle and depression status and the presence of hypercholesterolemia, among elderly individuals without known CVD. Methods During 2005–2007, 1190 elderly (aged 65 to 100 years) men and women (from Cyprus, Mitilini, Samothraki, Cephalonia, Crete, Lemnos, Corfu and Zakynthos) were enrolled. Socio-demographic, clinical and lifestyle factors were assessed through standard procedures. Symptoms of depression were evaluated using the short-form of the Geriatric Depression Scale (GDS, range 0–15). Dietary habits were assessed through a semi-quantitative food frequency questionnaire. Hypercholesterolemia was defined as total serum cholesterol > 200 mg/dL or use of lipids lowering medication. Results 44.6% of males and 61.9% of females had hypercholesterolemia (p < 0.001). Only, 63% of hypercholesterolemic participants were under special diet or pharmaceutical treatment. Hypercholisterolemic individuals had higher prevalence of obesity (43% vs. 25%), hypertension (76% vs. 57%) and diabetes (25% vs. 17%) compared with normal participants (p < 0.001). Furthermore, hypercholisterolemic participants showed higher depression levels (p = 0.002). After adjusting for various confounders, GDS score and BMI correlated with 13% (95%CI 0.98–1.30) and 14% (95%CI 0.99–1.31) higher likelihood of having hypercholesterolemia. Conclusion A considerable proportion of our elderly sample had hypercholesterolemia, while 1/3 of them were untreated. Furthermore, presence of hypercholesterolemia was correlated with depressive symptomatology and increased BMI.

Background: Depression has been linked to a large and growing economic and societal burden worldwide. In Europe, depression is one of the most frequent mental disorders across all age groups, but particularly in people aged 65 years and over, and higher depressive symptoms have been reported among individuals with chronic diseases (e.g., diabetes and heart disease)., Aim: To evaluate the role of adherence to the Mediterranean diet (MedDiet) in depression in a sample of older people living in the Mediterranean basin., Methods: Standard procedures were used to determine socio-demographic, lifestyle, and clinical characteristics of the participants, as well as their dietary habits, and depressive symptoms were evaluated using the Geriatric Depression Scale (GDS). Multi-adjusted logistic and linear regression analyses were carried out to evaluate the associations between participants' characteristics and depression., Results: Participants classified as having mild or severe depression were less educated and physically active, and more diabetic, and they reported less adherence to the MedDiet. Adherence to the MedDiet was associated with the absence of depression [(OR, 95% CI): 0.65, 0.50-0.85]. In addition, daily tea drinking was also related to the absence of depression [(OR, 95% CI): 0.51, 0.40-0.65]., Conclusions: Greater adherence to the MedDiet and daily tea drinking seem to have a beneficial effect on depressive symptoms in older adults., (Copyright © 2018 Elsevier Inc.

The aim of the present study was to evaluate the role of parental longevity and parental cardiovascular disease (CVD) history in CVD risk and successful aging of a random sample of older adults living in the Mediterranean basin and who participated in the MEDiterranean Islands (MEDIS) study. During 2005 to 2011, 2663 elders were voluntarily enrolled. A multidimensional successful aging index consisting of 10 components was used. Paternal and maternal longevity was defined as those older participants of whom both parents lived above the age of 90. The burden of CVD-related factors (CVD-RFs) was calculated as the total score of 4 major CVD-RFs (range 0-4). After adjustment, parental longevity was inversely associated with the burden of CVD-RFs ( P = .04). Moreover, parental longevity was positively associated with the older adults' successful aging score (β-coefficient [95% confidence interval]: .38 [0.06-0.71]). Parent's long living was revealed as an important factor for successful aging and for reduced CVD risk, suggesting that further research is needed in the genetic predisposition of longevity.

Objectives: By the end of the 2000s, the economic situation in many European countries started to deteriorate, generating financial uncertainty, social insecurity and worse health status. The aim of the present study was to investigate how the recent financial crisis has affected the lifestyle health determinants and behaviours of older adults living in the Mediterranean islands., Methods: From 2005 to 2015, a population-based, multi-stage convenience sampling method was used to voluntarily enrol 2749 older adults (50% men) from 20 Mediterranean islands and the rural area of the Mani peninsula. Lifestyle status was evaluated as the cumulative score of four components (range, 0 to 6), that is, smoking habits, diet quality (MedDietScore), depression status (Geriatric Depression Scale) and physical activity., Results: Older Mediterranean people enrolled in the study from 2009 onwards showed social isolation and increased smoking, were more prone to depressive symptoms, and adopted less healthy dietary habits, as compared to their counterparts participating earlier in the study (p<0.05), irrespective of age, gender, several clinical characteristics, or socioeconomic status of the participants (an almost 50% adjusted increase in the lifestyle score from before 2009 to after 2009, p<0.001)., Conclusions: A shift towards less healthy behaviours was noticeable after the economic crisis had commenced. Public health interventions should focus on older adults, particularly of lower socioeconomic levels, in order to effectively reduce the burden of cardiometabolic disease at the population level.

Introduction: Omega-3 polyunsaturated fatty acids (omega 3-PUFAs) seem to favorably affect cardiac hemodynamics and may benefit the clinical course of heart failure patients. The role of omega 3-PUFAs supplementation on the left and right ventricular function of patients with chronic compensated systolic heart failure, under optimal treatment, was studied., Methods: 205 consecutive patients with chronic compensated heart failure, due to ischemic (IHF) or dilated cardiomyopathy (DCM)-NYHA classification I-III, under optimal medical treatment, were enrolled. Participants were 1-to-1 randomized on 1000 mg omega 3-PUFA supplementation or no supplementation, in a non-blinded fashion. Echocardiographic assessment was performed at first visit and 6 months after. Plasma BNP and serum creatinine levels were also measured., Results: As compared with the control group, BNP levels in omega 3-PUFA intervention group were 34.6% lower (p=0.001); end-diastolic and end-systolic left ventricle dimensions were decreased by 2.5% (p=0.047) and 3.7% (p=0.01), maximum diameter of left atrium was decreased by 8.4% (p=0.004), left atrium ejection fraction was ameliorated by 6.03% (p=0.021) and as regards tissue Doppler parameters, TDI&#95;Etv/Atv was decreased in omega 3-PUFA intervention group by 6.3% (p=0.038). Moreover, improvement in diastolic indices was more prominent in subjects with DCM as compared to IHF patients., Conclusion: Omega 3-PUFA supplementation was associated with improved left diastolic function and decreased BNP levels in patients with chronic heart failure. These findings suggest a beneficial role of omega 3-PUFAs on the hemodynamic course of patients with systolic heart failure., (Copyright © 2016 Elsevier Inc. All rights reserved.)

The aim of this work was to evaluate factors associated with arterial blood pressure in a sample of older Mediterranean people without known cardiovascular disease. During 2005 to 2011, 2813 older (aged 65-100 years) individuals from 22 Mediterranean islands and the rural Mani region (Peloponnesus) voluntarily enrolled. Standard procedures were used to determine arterial BP and pulse pressure and for the evaluation of dietary habits (including tea and alcoholic beverages consumption), lifestyle, and anthropometric and clinical characteristics of the participants. Participants who reported low alcohol consumption (ie, 0-1 glasses per day) were less likely to have hypertension (odds ratio, 0.34; 95% confidence interval, 0.14-0.84) as compared with those who reported high alcohol consumption (ie, 5+ glasses per day). Adherence to the Mediterranean diet was inversely associated with mean arterial pressure (β coefficient, -0.18; 95% confidence interval, -0.33 to -0.16). Alcohol drinking remains an important modifiable risk factor for hypertension. Adherence to the Mediterranean diet was associated with decreased arterial peripheral resistance., (© 2014 Wiley Periodicals, Inc.)

Background: Climate variation has long been studied in relation to human health. The aim of the present work was to evaluate the relationship between environmental humidity, and air temperature with the prevalence of diabetes, among elderly islanders., Methods: During 2005-2011, 1959 elderly (aged 65 to 100 years) individuals from 13 Mediterranean islands were enrolled. Socio-demographic, clinical and lifestyle factors were assessed using standard procedures. Diabetes was defined as fasting blood glucose levels > 125 mg/dl. Relative environmental humidity was measured as a percentage of air moisture and mean daily temperature in degrees Celsius., Results: For the present analysis 713 men (74 ± 7 years) and 596 women (73 ± 7 years) with complete data were studied; 27% of both men and women had diabetes. The prevalence of diabetes was 42% in the elders living in high relative humidity areas (i.e., >70%) as compared with 24% among those living at low relative humidity residential areas (p < 0.001). After adjusting for age, sex and mean temperature, an increase in the area's relative humidity by 1 degree, increased the likelihood of having diabetes by 12% (OR = 1.12, 95% CI 1.05 to 1.20). No significant association was observed between mean temperature and diabetes (OR = 0.97, 95% CI 0.74, 1.26)., Conclusions: A considerable proportion of elderly, especially those living in high relative humidity areas, had diabetes. Further research is needed to confirm this observation and to understand the underlying mechanisms.

Data regarding the factors associated with depressive symptoms are limited, especially in postmenopausal women. The aim of this study was to investigate to what extent depressive symptoms were present in postmenopausal women, to explore characteristics associated with depressive symptoms and to determine if time since menopause was independently associated with depressive symptoms. Data collected within the Mediterranean Islands (MEDIS) Study, a health and nutrition survey of elderly people living on Mediterranean islands was used. A total of 851 postmenopausal women living in various Greek islands, Cyprus, and Malta participated in the study. Depressive symptoms were evaluated using the Geriatric Depression Scale (GDS). Age-adjusted logistic regression analysis showed that a year's increase in the time since menopause increased the likelihood of postmenopausal women having severe depressive symptoms by 3% (odds ratio [OR] per 1 year = 1.03, 95% CI 1.001-1.05). This positive association was also evident when other potential confounding factors (i.e, living conditions, financial status, physical activity, adherence to the Mediterranean diet, smoking habits, and several clinical conditions) were also taken into account in multivariable analyses. Primary health care practitioners and public health care authorities could use the findings of this study to identify depressive symptoms early in postmenopausal women.

In the 1960s, the recorded dietary pattern of Southern European populations was typical of the traditional Mediterranean diet. However, diets have been rapidly changing. The aim of the current work was to examine the extent by which present food habits of inhabitants residing in various Mediterranean islands uphold past dietary traditions of the Mediterranean diet. A population-based, multi-stage sampling method was used to voluntarily enroll 876 men and 936 women (aged > 65 years) from 12 Mediterranean islands. Demographic, behavioral, clinical, and dietary data were collected. Principal component analysis derived fruits, vegetables, and greens as part of the main dietary pattern across most Mediterranean regions. Surprisingly, Crete had the highest frequency of fast-food and sweets consumption. Malta had the lowest frequency of fish and vegetable consumption and the lowest MedDietScore. As Mediterranean populations gradually move away from traditional dietary patterns, public-health efforts to preserve these diets are needed.

Systolic and diastolic functions of both ventricles play a crucial role in the progression of chronic heart failure (CHF). As data about the role of dietary habits in ventricular dysfunction are lacking, we aimed to evaluate the relationship between biventricular diastolic and systolic function and dietary habits in patients with CHF. During 2007, 372 consecutive CHF patients were enrolled. Biventricular systolic and diastolic function was evaluated through echocardiography. Dietary habits were recorded using a food frequency questionnaire, and adherence to a Mediterranean diet was evaluated using the MedDietScore. The MedDietScore was positively correlated with log Smv, left atrial EF and V (p), and inversely correlated with log EA and log Emv/Amv levels (p < 0.05). After adjusting for potential confounders, only log E/A levels were inversely associated with the MedDietScore (p < 0.05). Following analysis per specific aliments, the log E/A ratio was inversely associated with fish intake and olive oil use; the log Emv/Amv ratio was inversely associated with fish intake; log Stv was positively associated with fish, olive oil and pasta intake; log LAKE was positively associated with olive oil use and alcohol drinking (all p < 0.05). This study demonstrated, in a cross-sectional design, a potential beneficial effect of a Mediterranean diet on biventricular systolic and diastolic function.

Aim: The aim of the present work was to evaluate the relationships between sociodemographic, clinical, and lifestyle characteristics and the presence of metabolic syndrome, among high and low altitude living elderly individuals without known CVD., Methods: During 2005-2011, 1959 elderly (aged 65 to 100 years) individuals from 13 Mediterranean islands were enrolled. Sociodemographic, clinical, and lifestyle factors were assessed using standard procedures. Metabolic syndrome was defined according to the (Adult Treatment Panel) ATP III criteria. Mountainous areas were defined those more than 400 meters in height., Results: For the present analysis 713 men and 596 women were studied; the prevalence of the metabolic syndrome was 29% (24% in men, 35% in women, p < 0.001). Furthermore, the prevalence of metabolic syndrome was 55% in the elders living in mountainous areas, as compared with 26% among those living at sea-level (p = 0.01). Similarly, the prevalence of hypertension, hypercholesterolemia, and obesity were higher in high altitude as compared with low altitude areas (all p-values < 0.01). After adjusting for various confounders, elders living in high altitude areas were 3.06-times more likely to have the metabolic syndrome than those living at sea-level (OR = 3.06, 95%CI 2.02-4.65). However, when the annual number of visits to health care centers was taken into account, the effect of altitude of living was not associated with the presence of the syndrome., Conclusions: A considerable proportion of mountainous living elderly had the metabolic syndrome. Public health actions need to be taken to reduce the burden of cardiometabolic disorders by enabling better access to health care, especially in remote mountainous rural areas.

Objectives: To evaluate the prevalence of low energy reporting (LER) and associations between LER and lifestyle, psychological and clinical parameters, in elderly people living in eastern Mediterranean islands., Methods: 1190 men and women, aged 65-100 years, participated in this cross-sectional study. Socio-demographic, clinical and lifestyle characteristics were recorded for the study participants. Among others, the ratio of energy intake to estimated basal metabolic rate (EI/BMR) was calculated and was used for the assessment of LER., Results: Prevalence of LER was 47.7%. Lower EI/BMR (i.e., higher risk for LER) was associated with older age (p=0.001), male sex (p<0.001), higher body mass index (BMI; p=0.04), lower adherence to the Mediterranean diet (p<0.001) and non-current smoking (p=0.007). The sex-specific analysis revealed that, lower EI/BMR values were associated with lower adherence to the Mediterranean diet and being non-current smoker in both men and women (p≤0.05), as well as with older age (p=0.01), higher BMI (p=0.02) and hypercholesterolemia (p=0.02), only in women., Conclusion: In elderly, several clinical and lifestyle factors seem to be related to LER, and they should be taken into account in their nutritional assessment., (Copyright © 2011 Elsevier Ireland Ltd.

Background: Right ventricular (RV) systolic function has been recognized as a prognostic factor in endstage heart failure (HF) patients and in the present study we evaluated the effect of this dysfunction on prognosis in patients with newly-diagnosed systolic HF., Methods and Results: We enrolled 180 consecutive patients with newly diagnosed systolic HF (ischemic or dilated cardiomyopathy). Echocardiographic evaluation was performed to assess biventricular function. Pulse-wave tissue Doppler imaging (TDI) readings were obtained from the lateral tricuspid annulus and the peak systolic annular velocity (Stv) was recorded. Patients were followed for a 2-year period and events (death or HF hospitalization) were recorded. During the follow-up, 79 patients (44%) had an adverse event. An inverse relationship was observed between the height of Stv and the probability of an event (odds ratio (OR) 0.716, 95% confidence interval (CI) 0.583-0.880, P=0.001), after controlling for potential confounders. Furthermore, creatinine clearance (CrCl) was inversely associated with the outcome: a 1-unit increase in CrCl was associated with a 0.98-times lower likelihood of having an event. When the analysis was stratified by CrCl < 60 ml/min or ≥ 60 ml/min, Stv predicted adverse events in both groups (CrCl < 60 ml/min: OR 0.62, 95%CI 0.39-0.98, P = 0.04; CrCl ≥ 60 ml/min: OR 0.78, 95%CI 0.61-1.01, P=0.06)., Conclusions: Pulse-wave TDI readings of peak systolic velocity at the lateral tricuspid annulus, reflecting RV systolic function, has prognostic significance in newly-diagnosed systolic HF patients.

Background: The aim of the present work was to evaluate various socio-demographic, clinical, lifestyle and psychological characteristics of elderly (> 65 years) and very elderly (> 90 years) individuals without known cardiovascular disease., Methods: During 2005-7, 1190 elderly (aged > 65) men and women (from Cyprus, Mitilini, Samothraki, Cephalonia, Crete, Lemnos, Corfu and Zakynthos) were randomly enrolled. Socio-demographic, clinical, psychological and lifestyle factors were assessed using standard questionnaires and procedures., Results: From all islands, the proportion of males aged 65-80, 80-90 and > 90 years was 71.8, 24.8 and 3.4%, respectively. The proportion of women, for the same age categories, was 80.4, 17.9 and 1.7%, respectively. Walking and other activities significantly declined with age (P < 0.001); however, nearly one in five participants over the age of 90 years remained physically active. Current smoking significantly declined in males as age increased (P < 0.001). All participants above the age of 90 years reported sleeping at noon. The proportion of participants living alone differs significantly (P < 0.001) across the three age groups. However, considerably more women live alone (men vs. women living alone: aged 65-80 years 12 vs. 37%; 80-90 years 16 vs. 55%; > 90 years 52 vs. 55%). Dietary characteristics of The Mediterranean Islands Study (MEDIS) sample display a favourable adherence to dietary recommendations (Mediterranean diet)., Conclusion: A favourable adherence to the Mediterranean diet, mid-day naps and smoking cessation with an increase in age was characteristic of our elderly population. Future research should further evaluate whether the aforementioned characteristics are associated with longevity beyond the average life expectancy.

Mental disorders are among the leading causes for disability, with depression a common compilation of hypertension, and other metabolic disorders (lipid abnormalities, diabetes, and obesity). Fat (lipid) intake plays a significant role in the prevention of various chronic diseases. The present cross-sectional study was conducted to evaluate the role of fat intake in depression among hypertensive elderly people living in the Mediterranean Islands. Fish lipid intake was inversely associated with depression status among hypertensive participants (P <  0.01), while fat intake of sweets and legumes was positively associated with depression in participants with no clinical condition. The aforementioned findings may state hypotheses for further investigation about the role of dietary fat on the depression status of elderly people.

Objective: To investigate whether the socio-economic status (SES) of elderly eastern Mediterranean islanders is associated with their dietary habits, particularly with adherence to the traditional Mediterranean diet., Design: Cross-sectional., Setting: Adherence to the Mediterranean diet was measured by the MedDietScore (range: 0-55), whereas SES was estimated using education and financial status., Subjects: During 2005-2007, 300 men and women from Cyprus, 100 from Samothraki, 142 from Mitilini, 114 from Kefalonia, 131 from Crete, 150 from Lemnos, 150 from Corfu and 103 from Zakynthos (aged 65-100 years), free of known chronic diseases, participated in the survey., Results: Multiple linear regression analysis revealed that belonging to the highest SES was associated with a higher MedDietScore (P < 0.01), after adjusting for potential sociodemographic, lifestyle, dietary and clinical confounders. A significant positive association was also found between MedDietScore and years of school (P = 0.004), as well as financial status (P = 0.001)., Conclusions: Older Greek people of higher SES seem to follow a relatively healthier diet. Both education and income seem to play a role in this issue. Thus, public health policy makers should focus on people with low SES in order to improve their quality of diet and, consequently, their health status.

Introduction: There are only limited data about the role of renal function in the development of left ventricular systolic dysfunction in patients with an acute coronary syndrome (ACS). We sought to investigate whether renal insufficiency is an independent predictor for systolic dysfunction among patients who had an ACS., Methods: During 2006-2007, 814 consecutive patients who presented with an ACS event were enrolled prospectively; of these, 284 men (65 ± 14 years) and 71 women (71 ± 12 years) developed left ventricular systolic dysfunction (ejection fraction <40%), 306 men (64 ± 12 years) and 78 women (67 ± 10 years) had preserved left ventricular systolic function (ejection fraction >50%), while the rest of the patients (n=75), with ejection fraction between 40-50%, were excluded from this analysis. Creatinine clearance rates were estimated by the Cockcroft-Gault formula., Results: Eight percent of patients presented with severe and 30% with moderate renal dysfunction. Multiple logistic regression analysis revealed that a 10-unit increase of creatinine clearance levels decreases the odds of developing left ventricular systolic dysfunction by 8% (95%CI per 1 unit: 0.986-0.998), after controlling for potential confounders. Moreover, brain natriuretic peptide levels were inversely correlated with creatinine clearance (r=-0.378, p<0.001). When brain natriuretic peptide was entered into the model, creatinine clearance was not associated with left ventricular systolic dysfunction (OR=0.997, 95%CI 0.989-1.005)., Conclusions: The role of renal insufficiency in the development of left ventricular systolic dysfunction seems to be partially explained by plasma brain natriuretic peptide levels, suggesting a potential pathophysiological mechanism. Thus, patients with impaired creatinine levels and elevated brain natriuretic peptide levels should receive more aggressive medical care, as they are prone to developing left ventricular systolic dysfunction.

Dietary fats have long been associated with human health, and especially cardiovascular disease (CVD). Some observational studies have shown that reduction in dietary fats, and particularly cholesterol is associated with lower cardiovascular risk; however, other prospective studies or randomized controlled trials of dietary fat reduction or modification have shown varying results on CVD morbidity and mortality. In this work we evaluated the relationships between dietary fats and a cluster of CVD risk factors (i.e., diabetes, obesity, hypercholesterolemia, hypertension), among elderly individuals without known CVD. In particular, dietary and clinical data from 1486 elderly (aged 65 to 100 years) men and women living in Cyprus, Mitilini, Samothraki, Cephalonia, Crete, Lemnos, Syros, Naxos, Corfu and Zakynthos islands, and participated in the MEDIS study, were analysed. Data analysis revealed that 18.5% of males and 33.3% of females had three or four cardiovascular disease risk factors; the major source of fat was olive oil (mean intake for men and women 50.0 +/- 19.3 g/day and 46.0 +/- 16.8 g/day, p < 0.001). In addition it was observed that a 5% increase in energy adjusted fat intake from meat was associated with a 21% increase in the likelihood of having one additional CVD risk factor (95%CI 6%-39%); no significant associations were observed regarding the other types of fat consumed by the elderly participants. These findings may state a hypothesis that the consumption of fat only from meat or its products seems to increase the burden of CVD risk factors among CVD-free, elderly people.
