Lessons from Studies in Middle-Aged and Older Adults Living in Mediterranean Islands: The Role of Dietary Habits and Nutrition Services

Background. Islands in the Mediterranean basin share particular habits and traditions and greater life expectancy than other European regions. In this paper, particular interest has been given to the effect of the Mediterranean diet, as well as nutritional services on CVD risk, on Mediterranean islands. Methods. Published results from observational studies were retrieved from electronic databases (Pubmed and Scopus) and summarized. Results. Prevalence of CVD risk factors is increased. Adherence to the Mediterranean diet was moderate, even among the elderly participants. Furthermore, the presence of a dietician was associated with higher adherence to the Mediterranean dietary pattern and consequently lowers CVD risk. Conclusion. Adherence to the Mediterranean diet is reduced, while the prevalence of CVD risk factors is increasing at alarming rates. Public health nutrition policy has the opportunity to improve the health and quality of life of people living in isolated insular areas of the Mediterranean basin

Η έννοια του συμβόλου του ίσον (=) στη Γεωμετρία

Η έλλειψη ερευνητικών μελετών όσον αφορά την ισότητα και την χρήση του συμβόλου του ίσον στον τομέα της Γεωμετρίας, εν αντιθέσει με τον τομέα της Άλγεβρας, οδήγησε στον σχεδιασμό της παρούσας διπλωματικής εργασίας. Η παρούσα διπλωματική εργασία αντλεί από τη θεωρητική-μεθοδολογική οπτική των Moutsios-Rentzos, Kritikos και Kalavasis (in press) για να μελετήσει αν διαφέρει η χρήση του ίσον ανάμεσα σε Άλγεβρα και Γεωμετρία, πώς εμφανίζεται το ίσον στα σχολικά εγχειρίδια, πώς αντιμετωπίζουν οι εκπαιδευτικοί το σύμβολο, πώς βιώνουν τις διαφορετικές χρήσεις του και τι θα πρότειναν οι ίδιοι σε συναδέλφους τους, στους συγγραφείς των βιβλίων και στην ομάδα σχεδιασμού της ύλης. Η έρευνα κινήθηκε σε τρεις άξονες, πρώτον τη μελέτη της υπάρχουσας βιβλιογραφίας που αφορά την ισότητα και την χρήση του ίσον στην Άλγεβρα και συσχετισμός αυτής με τη Γεωμετρία, δεύτερον ανάλυση των σχολικών εγχειριδίων με ιδιαίτερη βαρύτητα στις παραγράφους της Γεωμετρίας στη Β’ και Γ’ Γυμνασίου και στην Α’ Λυκείου και τρίτον ανάλυση των συνεντεύξεων που διεξήγαμε με εκπαιδευτικούς που αφορούσαν την χρήση του ίσον στη Γεωμετρία. Οι εκπαιδευτικοί μπορούν να διακρίνουν τις διαφορές του ίσον ανάμεσα σε Άλγεβρα και Γεωμετρία, με σαφείς οδηγίες θα μπορούσαν να διακρίνουν και τις διαφορές αποκλειστικά στη Γεωμετρία. Το βιβλίο καθηγητή χρήζει ανανέωσης με οδηγίες που αφορούν την έννοια της ισότητας στη Γεωμετρία ώστε οι εκπαιδευτικοί να μπορούν το συμβουλεύονται.The lack of research with respect to the notion of equality and the equal sign in Geometry, in contrast to the Algebra, was led to the design of the present dissertation. The dissertation drew upon the theoretical-methodological framework introduced by Moutsio-Rentzos, Kritikos and Kalavasis (in press) to investigate whether the equal sign is used in Geometry is used differently from Algebra or not, the way it is presented in school textbooks, the ways the teachers deal with this sign, the ways they experience differences in its use and what they would suggest to their colleagues, to the authors of the school books as well as the curriculum design team. The research was conducted in three axes. Firstly, the existing literature concerning equality and the use of equals sign in Algebra was studied as well as the relation between Algebra and Geometry. Secondly, school textbooks were analysed, emphasizing on the paragraphs of Geometry in the 2nd and 3rd year of Junior High School (Gymnasio) and 1st year of Senior High School (Lykeio). Thirdly, an analysis of the interviews conducted among teachers concerning the use of equals sing in Geometry was also included. Teachers can distinguish differences between Algebra and Geometry, while with clear instructions they would be able to distinguish differences within Geometry as well. The teacher's book calls for renewal so that it could include instructions on the concept of equality in Geometry in order for teachers to consult it

Skeletal muscle mass in relation to 10 year cardiovascular disease incidence among middle aged and older adults: the ATTICA study

Skeletal muscle mass (SMM) is inversely associated with cardiometabolic health and the ageing process. The aim of the present work was to evaluate the relation between SMM and 10 year cardiovascular disease (CVD) incidence, among CVD-free adults 45+ years old. METHODS: ATTICA is a prospective, population-based study that recruited 3042 adults without pre-existing CVD from the Greek general population (Caucasians; age ≥18 years; 1514 men). The 10 year study follow-up (2011-2012) captured the fatal/non-fatal CVD incidence in 2020 participants (50% men). The working sample consisted of 1019 participants, 45+ years old (men: n=534; women: n=485). A skeletal muscle mass index (SMI) was created to reflect SMM, using appendicular skeletal muscle mass (ASM) standardised by body mass index (BMI). ASM and SMI were calculated with specific indirect population formulas. RESULTS: The 10 year CVD incidence increased significantly across the baseline SMI tertiles (p<0.001). Baseline SMM showed a significant inverse association with the 10 year CVD incidence (HR 0.06, 95% CI 0.005 to 0.78), even after adjusting for various confounders. Additionally, participants in the highest SMM tertile had 81% (95% CI 0.04 to 0.85) lower risk for a CVD event as compared with those in the lowest SMM tertile. CONCLUSIONS: The presented findings support the importance of SMM evaluation in the prediction of long-term CVD risk among adults 45+ years old without pre-existing CVD. Preservation of SMM may contribute to CVD health

The burden of disease in Greece, health loss, risk factors, and health nancing, 2000–16: an analysis of the Global Burden of Disease Study 2016

Background Following the economic crisis in Greece in 2010, the country's ongoing austerity measures include a substantial contraction of health-care expenditure, with reports of subsequent negative health consequences. A comprehensive evaluation of mortality and morbidity is required to understand the current challenges of public health in Greece. Methods We used the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 to describe the patterns of death and disability among those living in Greece from 2000 to 2010 (pre-austerity) and 2010 to 2016 (post-austerity), and compared trends in health outcomes and health expenditure to those in Cyprus and western Europe. We estimated all-cause mortality from vital registration data, and we calculated cause-specific deaths and years of life lost. Age-standardised mortality rates were compared using the annualised rate of change (ARC). Mortality risk factors were assessed using a comparative risk assessment framework for 84 risk factors and clusters to calculative summary exposure values and population attributable fraction statistics. We assessed the association between trends in total, government, out-of-pocket, and prepaid public health expenditure and all-cause mortality with a segmented correlation analysis. Findings All-age mortality in Greece increased from 944·5 (95% uncertainty interval [UI] 923·1–964·5) deaths per 100 000 in 2000 to 997·8 (975·4–1018) in 2010 and 1174·9 (1107·4–1243·2) in 2016, with a higher ARC after 2010 and the introduction of austerity (2·72% [1·65 to 3·74] for 2010–16) than before (0·55% [0·24 to 0·85] for 2000–10) or in western Europe during the same period (0·86% [0·54 to 1·17]). Age-standardised reduction in ARC approximately halved from 2000–10 (−1·61 [95% UI −1·91 to −1·30]) to 2010–16 (−0·87% [–2·03 to 0·20]), with post-2010 ARC similar to that in Cyprus (−0·86% [–1·4 to −0·36]) and lower than in western Europe (−1·14% [–1·48 to −0·81]). Mortality changes in Greece coincided with a rapid decrease in government health expenditure, but also with aggregate population ageing from 2010 to 2016 that was faster than observed in Cyprus. Causes of death that increased were largely those that are responsive to health care. Comparable temporal and age patterns were noted for non-fatal health outcomes, with a somewhat faster rise in years lived with disability since 2010 in Greece compared with Cyprus and western Europe. Risk factor exposures, especially high body-mass index, smoking, and alcohol use, explained much of the mortality increase in Greek adults aged 15–49 years, but only explained a minority of that in adults older than 70 years. Interpretation The findings of increases in total deaths and accelerated population ageing call for specific focus from health policy makers to ensure the health-care system is equipped to meet the needs of the people in Greece

Mental Disorders, Musculoskeletal Disorders and Income-Driven Patterns: Evidence from the Global Burden of Disease Study 2017

Background: The aim of the present study was to use the extensive Global Burden ofDiseases, Injuries, and Risk Factors Study (GBD) database from 1990-2017 to evaluate the levels andtemporal correlation trends between disability adjusted life years (DALYs) attributed tomusculoskeletal (MSK) disorders, all mental disorders collectively and by mental disorder subcategory. Methods: We utilized results of the GBD 2017 to describe the correlation patterns betweenDALYs due to MSK disorders, mental disorders and other diseases among 195 countries. Mixedmodel analysis was also applied. Results: A consistent relation was reported between age-adjustedDALYs attributed to MSK and mental disorders (in total) among the 195 countries, in both sexes,for 1990 to 2017 (1990 Rho = 0.487; 2017 Rho =0.439 p < 0.05). Distinct regional and gender correlationpatterns between age-adjusted DALYs due to MSK and mental disorders were reported. Nocorrelation was reported between DALYs due to MSK and all mental disorders collectively, amongLow- or Middle-income countries. However, in High-income countries (HICs), the correlation wasstrong and consistent between 1990 and 2017 (1990 Rho = 0.735; 2017 Rho = 0.727, p < 0.05). Conclusions: The reported correlation patterns call for targeted preventive strategies andintervention policies for mental and MSK disorders internationally. Special attention is neededamong HICs

Population prevalence of edentulism and its association with depression and self-rated health

Edentulism is associated with various adverse health outcomes but treatment options in low- and middle-income countries (LMICs) are limited. Data on its prevalence and its effect on mental health and overall-health is lacking, especially from LMICs. Self-reported data on complete edentulism obtained by standardized questionnaires on 201,953 adults aged ≥18 years from 50 countries which participated in the World Health Survey (WHS) 2002-2004 were analyzed. Age and sex-standarized edentulism prevalence ranged from 0.1% (95% CI = 0.0-0.3) (Myanmar) to 14.5% (95% CI = 13.1-15.9) (Zimbabwe), and 2.1% (95% CI = 1.5-3.0) (Ghana) to 32.3% (95% CI = 29.0-35.8) (Brazil) in the younger and older age groups respectively. Edentulism was significantly associated with depression (OR 1.57, 95% CI = 1.23-2.00) and poor self-rated health (OR 1.38, 95% CI = 1.03-1.83) in the younger group with no significant associations in the older age group. Our findings highlight the edentulism-related health loss in younger persons from LMICs. The relative burden of edentulism is likely to grow as populations age and live longer. Given its life-long nature and common risk factors with other NCDs, edentulism surveillance and prevention should be an integral part of the global agenda of NCD control

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

Measuring performance on the Healthcare Access and Quality Index for 195 countries and territories and selected subnational locations: a systematic analysis from the Global Burden of Disease Study 2016

Background: A key component of achieving universal health coverage is ensuring that all populations have access to quality health care. Examining where gains have occurred or progress has faltered across and within countries is crucial to guiding decisions and strategies for future improvement. We used the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) to assess personal health-care access and quality with the Healthcare Access and Quality (HAQ) Index for 195 countries and territories, as well as subnational locations in seven countries, from 1990 to 2016. Methods: Drawing from established methods and updated estimates from GBD 2016, we used 32 causes from which death should not occur in the presence of effective care to approximate personal health-care access and quality by location and over time. To better isolate potential effects of personal health-care access and quality from underlying risk factor patterns, we risk-standardised cause-specific deaths due to non-cancers by location-year, replacing the local joint exposure of environmental and behavioural risks with the global level of exposure. Supported by the expansion of cancer registry data in GBD 2016, we used mortality-to-incidence ratios for cancers instead of risk-standardised death rates to provide a stronger signal of the effects of personal health care and access on cancer survival. We transformed each cause to a scale of 0–100, with 0 as the first percentile (worst) observed between 1990 and 2016, and 100 as the 99th percentile (best); we set these thresholds at the country level, and then applied them to subnational locations. We applied a principal components analysis to construct the HAQ Index using all scaled cause values, providing an overall score of 0–100 of personal health-care access and quality by location over time. We then compared HAQ Index levels and trends by quintiles on the Socio-demographic Index (SDI), a summary measure of overall development. As derived from the broader GBD study and other data sources, we examined relationships between national HAQ Index scores and potential correlates of performance, such as total health spending per capita. Findings: In 2016, HAQ Index performance spanned from a high of 97·1 (95% UI 95·8–98·1) in Iceland, followed by 96·6 (94·9–97·9) in Norway and 96·1 (94·5–97·3) in the Netherlands, to values as low as 18·6 (13·1–24·4) in the Central African Republic, 19·0 (14·3–23·7) in Somalia, and 23·4 (20·2–26·8) in Guinea-Bissau. The pace of progress achieved between 1990 and 2016 varied, with markedly faster improvements occurring between 2000 and 2016 for many countries in sub-Saharan Africa and southeast Asia, whereas several countries in Latin America and elsewhere saw progress stagnate after experiencing considerable advances in the HAQ Index between 1990 and 2000. Striking subnational disparities emerged in personal health-care access and quality, with China and India having particularly large gaps between locations with the highest and lowest scores in 2016. In China, performance ranged from 91·5 (89·1–93·6) in Beijing to 48·0 (43·4–53·2) in Tibet (a 43·5-point difference), while India saw a 30·8-point disparity, from 64·8 (59·6–68·8) in Goa to 34·0 (30·3–38·1) in Assam. Japan recorded the smallest range in subnational HAQ performance in 2016 (a 4·8-point difference), whereas differences between subnational locations with the highest and lowest HAQ Index values were more than two times as high for the USA and three times as high for England. State-level gaps in the HAQ Index in Mexico somewhat narrowed from 1990 to 2016 (from a 20·9-point to 17·0-point difference), whereas in Brazil, disparities slightly increased across states during this time (a 17·2-point to 20·4-point difference). Performance on the HAQ Index showed strong linkages to overall development, with high and high-middle SDI countries generally having higher scores and faster gains for non-communicable diseases. Nonetheless, countries across the development spectrum saw substantial gains in some key health service areas from 2000 to 2016, most notably vaccine-preventable diseases. Overall, national performance on the HAQ Index was positively associated with higher levels of total health spending per capita, as well as health systems inputs, but these relationships were quite heterogeneous, particularly among low-to-middle SDI countries. Interpretation: GBD 2016 provides a more detailed understanding of past success and current challenges in improving personal health-care access and quality worldwide. Despite substantial gains since 2000, many low-SDI and middle-SDI countries face considerable challenges unless heightened policy action and investments focus on advancing access to and quality of health care across key health services, especially non-communicable diseases. Stagnating or minimal improvements experienced by several low-middle to high-middle SDI countries could reflect the complexities of re-orienting both primary and secondary health-care services beyond the more limited foci of the Millennium Development Goals. Alongside initiatives to strengthen public health programmes, the pursuit of universal health coverage hinges upon improving both access and quality worldwide, and thus requires adopting a more comprehensive view—and subsequent provision—of quality health care for all populations
