Lifestyle and health determinants of cardiovascular disease among Greek older adults living in Eastern Aegean Islands: An adventure within the MEDIS study.

OBJECTIVE: The aim of the present study was to evaluate lifestyle and health determinants of cardiovascular disease (CVD) risk among Greek elderly residents living in Eastern Aegean islands, in both Greece and Turkey. METHODS: Under the context of the MEDIS study, 724 older adults (aged 65 to 100 years) from 8 Eastern Aegean Sea Greek islands (n=100 living in Samothrace, 142 in Lesvos, 150 in Limnos, 76 in Ikaria, 52 in Kassos, 149 in Rhodes and Karpathos) and from Turkey (n=55older adults of Greek origin living on Gökçeada Island) were voluntarily recruited. Overall cardiometabolic risk was measured as the sum (range 0-4) of four common CVD risk factors (hypertension, diabetes, dyslipidemia and obesity). RESULTS: Greek islanders had higher CVD scores compared to Greeks of Gökçeada (1.9±1.1 vs 1.4±1.0 risk factors / participant, p<0.001). Further analysis revealed that the diet of Greek islanders was similar to the traditional Mediterranean diet; however, these individuals demonstrated 2-times higher odds (95% CI, 1.04-3.87) for having hypertension, 1.53-times higher odds (95% CI, 0.66-3.54) for having diabetes, 3.29-times higher odds (95% CI, 1.58-6.81) for having hypercholesterolemia; whereas they had 0.78-times lower odds (95% CI, 0.40-1.52) for being obese, compared to elderly Greek adults living on Gökçeada. CONCLUSIONS: Overall, CVD risk seems to be low among Eastern Aegean Islanders; certain differences in CVD risk factors exist between Greek islanders and their counterparts living in Gökçeada, and those differences may be attributed to various environmental, cultural and lifestyle factors

Skeletal muscle mass and body fat in relation to successful ageing of older adults: The multi-national MEDIS study

BACKGROUND: The determinants that promote successful ageing still remain unknown. The aim of the present work was to evaluate the role of skeletal muscle mass and body fat percentage (BF%), in the level of successful ageing. METHODS: during 2005-2011, 2663 older (aged 65-100 years) from 21 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece were voluntarily enrolled in the study. Appendicular skeletal muscle mass (ASM), skeletal muscle mass index (SMI) and BF% were calculated using population formulas. Dietary habits, energy intake, expenditure and energy balance were derived throughout standard procedures. A successful ageing index ranging from 0 to 10 was used. RESULTS: The mean ASM mass was 24±6.0kg, the SMI was 0.84±0.21 and the BF% was 44%. Females had lower SMI and higher BF% in comparison with males, respectively [(SMI: 0.66±0.09 vs. 1.03±0.11; BF%: 51% vs. 34%, (p<0.001)]. High successful agers had better rates in ASM (p=0.01), SMI (p<0.001) and BF% (p<0.001), compared with the medium and low successful ones. Changes in SMI [b-coefficient (95% CI):2.14 (1.57 to 2.71)] were positively associated with successful ageing, while changes in BF% [b-coefficient (95% CI): -0.04 (-0.05 to -0.03)] were inversely associated with successful ageing. Results from sensitivity analysis showed that the effects of variations on body composition were consistent, less pronounced in the positive energy balance group and more pronounced among the oldest old. CONCLUSIONS: Body composition changes seem to be associated with lower quality of life in the older adults, as measured through successful ageing

Feasibility and impact of a short training course on frailty destined for primary health care professionals

BACKGROUND: There is an unmet need for training primary health care professionals on frailty, especially in countries where geriatrics is still emerging. PURPOSE: We aimed to evaluate the feasibility and efficacy of a training course for primary health care professionals on the detection, assessment, and management of frailty. METHODS: A single-day training course, developed and facilitated by three physicians trained in geriatrics abroad, was organized by the Aristotle University of Thessaloniki Primary Hearth Care Research Network. Primary health care professionals' attitudes, knowledge, and everyday practices regarding frailty were assessed by self-administered anonymous questionnaires (using Likert-type scales) at three time-points (before, upon completion of the training course, and 3 months afterward). RESULTS: Out of 31 participants (17 physicians, 12 nurses, 2 health visitors; 87.1% women; mean age 46.4 years), 31(100%) filled in the first, 30(97%) the second, and 25(81%) the third questionnaire. Improvements were reported in familiarization with the frailty syndrome (p = 0.041) and in self-perception of knowledge and skills to detect (p < 0.001) and manage (p < 0.001) frailty, that were also sustained 3 months afterward (p = 0.001 and p = 0.003 respectively). Improvement was also observed in the attitude that frailty is an inevitable consequence of aging (p = 0.007) and in the frequency of application of screening (but not management) strategies, 3 months following the workshop compared to baseline (p = 0.014). Participants reported less disagreement with the statement that systematic screening for frailty was unfeasible in their daily practice at 3 months compared to baseline (p = 0.006), mainly due to time restrictions. CONCLUSION: A short skill-oriented training course can significantly and sustainably improve primary health care professionals' attitudes and practices regarding frailty

Primary care professionals’ experiences during the first wave of the COVID-19 pandemic in Greece: a qualitative study

Background: The coronavirus outbreak (COVID-19) tested health care systems worldwide. This qualitative study aimed to explore and understand the experiences, beliefs and concerns of Primary Care Professionals (PCPs) regarding the preparedness and response of primary care to the first wave of the pandemic in Greece, a country where a public structured primary care system has been developing. Methods: We conducted semi-structured telephone interviews with 33 PCPs (General Practitioners, community General Internal Medicine Specialists, community Paediatricians and nurses) recruited from all regions of Greece after the first wave of the pandemic (June 2020). Interviews were transcribed verbatim, data were anonymised and analysed. Thematic analysis was applied developing a conceptual framework. Results: Four main themes were identified: a) Primary care unit adaptation and issues faced during the pandemic; b) Management of suspected COVID-19 cases; c) Management of non-suspected cases; d) Consequences of the pandemic. In the first phase of the pandemic, remote management of suspected cases and their referral to the hospital were preferred as a result of a shortage of personal protective equipment and inaccessibility to coronavirus testing in primary care. Due to the discontinuation of regular medical services and the limited in-person contact between doctors and patients, chronic disease management and prevention programmes were left behind. Social and emotional consequences of the pandemic, such as workplace stigma, isolation and social seclusion, deriving from fear of viral transmission, as well as burnout symptoms and exhaustion were commonly experienced among PCPs. Positive consequences of the pandemic were considered to be the recognition of the importance of an empowered public healthcare system by citizens and the valuable insight, knowledge and experience professionals gained in times of crisis. Conclusions: Primary care has a key role to play during and after the pandemic by using its information infrastructure to identify at-risk groups, detect new cases of COVID-19, provide care according to needs, and carry out vaccination programmes. Central coordination and empowerment of primary care will increase its effectiveness, via public awareness, holistic patient management, and unburdening of hospitals

Residential altitude and fish consumption : effect on systolic blood pressure in elderly : MEDIS study cross-sectional results

Background/Aims: Frequent consumption of fish is associated with decreased SBP levels. Both aging and living at high altitude are associated with significant increases in Systolic Blood Pressure (SBP) levels. The aim of this analysis was to examine the potential interaction between fish consumption and high altitude on SBP in elderly cohort. Methods: Mediterranean islands study (MEDIS) recruited 2749 older (aged 65+ years) individuals from 2005-2015. Participants were selected from 21 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece. Dietary habits, energy intake, physical activity status, socio-demographic characteristics and clinical profile aspects (blood pressure) were measured. The altitude of the area was also recorded.

Is Parental Longevity Associated With the Cardiovascular Risk and the Successful Aging of Their Offspring? Results From the Multinational MEDIS Study

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

Anti-Inflammatory Nutrition and Successful Ageing in Elderly Individuals: The Multinational MEDIS Study

BACKGROUND: The role of diet and inflammation in successful ageing is not transparent, and as such, is still being investigated. The aim of the present work was to evaluate the inflammatory potential of dietary habits in the successful ageing of a random sample of older adults living in the Mediterranean basin and who participated in the MEDIS (MEDiterranean ISlands) study. METHODS: During 2005-2016, 3,128 older adults (aged 65-100 years) from 24 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece were enrolled in the study. A multidimensional successful ageing index consisting of 10 components was employed. A validated and reproducible Food Frequency Questionnaire (FFQ) was used to evaluate the dietary habits of the older adults. A nutrition anti-inflammatory (NAI) score based on the participants' specific dietary habits was assessed. RESULTS: Participants with high NAI scores (proinflammatory nutrition) had a higher prevalence of hypercholesterolemia and lower levels of successful ageing. After adjusting for several confounders, the NAI score was associated with successful ageing (-0.03, 95% CI -0.5 to -0.006). Stratified analysis by gender and advanced age revealed heterogeneity in the NAI score, predicting successful ageing. CONCLUSIONS: The inflammatory potential of nutrition was reported as an important factor for successful ageing, suggesting that further research is needed on the role of anti- and proinflammatory dietary habits in healthy and successful ageing

Association between siesta (daytime sleep), dietary patterns and the presence of metabolic syndrome in elderly living in Mediterranean area (MEDIS study):The moderating effect of gender

Objectives: Several lifestyle parameters including diet, physical activity and sleep were associated in isolation with the presence of Metabolic Syndrome (MetS) in adults, to date there is a paucity of studies which evaluated their combined role aging populations and especially with respect to gender. Therefore, the aim of the present study was to provide a global consideration of the lifestyle factors associated with MetS among elderly individuals. Design: Cross-sectional observational study. Setting: 21 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece. Participants: during 2005-2015, 2749 older (aged 65-100 years) from were voluntarily enrolled in the study. Measurements: Dietary habits, energy intake, physical activity status, sociodemographic characteristics, lifestyle parameters (sleeping and smoking habits) and clinical profile aspects were derived through standard procedures. The presence of MetS was defined using the definition provided by NCEP ATP III (revised) and cluster analysis was used to identify overall dietary habit patterns. Results: The overall prevalence of MetS in the study sample was 36.2%, but occurred more frequently in females (40.0% vs. 31.8%, respectively, p=0.03). Individuals with MetS were more likely to sleep during the day (89.4% vs. 76.8% respectively, p=0.039) and frequent ‘siesta’ was positively linked to the odds of MetS presence in females (Odds Ratio (OR) =3.43, 95% Confidence Intervals (CI): 1.08-10.9), but not for men (p=0.999). The lower carbohydrate (i.e., 45.2% of total daily energy, 120±16gr/day) dietary cluster was inversely associated with the odds for MetS presence, but only for men (OR=0.094, 95%CI: 0.010-0.883). Conclusions: Lifestyle parameters including sleep and diet quality are strongly associated with the presence of MetS in elderly cohort, but different their level of influence appears to be different, depending on gender. Further research is needed to better consider the role of lifestyle characteristics in the management of MetS in clinical practice

The association between lifestyle-related factors and plasma homocysteine levels in healthy individuals from the “ATTICA” Study

Objective: The aim of this work was to investigate the associations between homocysteine levels and several lifestyle-related factors, in a population-based sample of Greek adults. Methods: During 2001-2002, we randomly enrolled 1128 men and 1154 women, from Athens area. The sampling was stratified by the age-gender distribution of the underlying population. Among several demographic, lifestyle, clinical and biochemical factors, we measured plasma total homocysteine levels. For the present analysis, we excluded people who had a history of cardiovascular disease. Results: Homocysteine values were higher in men as compared to women (14.5 +/- 6 vs. 10.8 +/- 3.5 mu mol/l, p &lt; 0.001). Twenty-five percent of men and 15% of women had plasma homocysteine levels &gt; 14 mu mol/l. Postmenopausal women had higher homocysteine levels (12.0 +/- 5.2 vs. 9.9 +/- 2.9 mu mol/l, p &lt; 0.001). The lifestyle factors most strongly associated with plasma total homocysteine were number of cigarettes smoked (r = 0.12, p = 0.004), fruits (r = -0.12, p = 0.006) and vegetables consumption (r = -0.15, p = 0.02), alcohol (r = 0.11, p = 0.04) and coffee drinking (r = 0.10, p = 0.03). Additionally, aerobic exercise was related with lower homocysteine levels as compared to anaerobic or sedentary life (11.0 +/- 2.6 vs. 12.4 +/- 2.5 vs. 12.5 +/- 2.3 mu mol/l, respectively, p = 0.04). Multivariate analysis after adjusting for several potential confounders confirmed the previous associations. No relationship was observed of homocysteine with the Mediterranean diet score (r = 0.02, p = 0.85). Conclusions: Several lifestyle-related factors were associated with homocysteine levels. Identifying and understanding modifiable factors related to homocysteine, a possible risk factor for vascular disease, might be especially important for the public health.

Determinants of Physical Inactivity Among Men and Women From Greece: A 5-Year Follow-Up of the ATTICA Study

Objective: We sought to evaluate factors that are associated with physical activity changes among adults within a 5-year period. Methods: From May 2001 to December 2002 we randomly enrolled 1514 men and 1528 women without any evidence of cardiovascular or any other chronic disease. The sampling was stratified by the age-gender distribution of the greater area of Athens. Weekly energy expenditure assessed by considering frequency, duration, and intensity of sports-related physical activity. During 2006, the 5-year follow-up was performed in 1955 participants, which included, among others, current physical activity status. Results: A total of 587 (61%) men and 673 (68%) women were classified as physically inactive at baseline, whereas 661 (69%) men and 728 (73%) women were classified as physically inactive at follow-up; thus, a 13% increase in physical inactivity rate was observed in men and a 7% in women during the follow-up period (p &lt; 0.01). Multivariate analysis revealed that male gender, being a nonsmoker, healthy eating, better self-reported quality-of-life, and lower prevalence of hypercholesterolemia and incidence of cardiovascular disease were the characteristics of people that remained physically active; advanced age, anxiety and depression, overweight, and low quality-of-life were the baseline predictors of physical inactivity among initially active participants, which also had a greater incidence of cardiovascular disease. Conclusions: Gender, aging, psychological disorders, body mass, smoking, dietary habits, perceived health status, and quality-of-life were the most important discriminating factors of physical activity changes. © 2008 Elsevier Inc.
