Abstract
Background/Introduction
The association between sarcopenia and nonalcoholic fatty liver (NAFL) is highlighted in recent epidemiological studies, although results remain inconsistent.
Purpose
This study aimed to examine the association of low skeletal muscle mass with NAFL as well as the potential mediating effect of waist circumference on the examined association.
Methods
At baseline, 3,042 participants from the Attica region of Greece were recruited. NAFL was assessed through hepatic steatosis index (HSI). Skeletal muscle mass index (SMI) was indirectly calculated using a standard validated procedure.
Results
Ranking from 1st to 3rd SMI tertiles NAFL rate was 45%, 33% and 22%, respectively (p<0.001). Multi-adjusted logistic regression analysis revealed that participants assigned in the 2nd (Odds Ratio (OR): 0.50, 95% Confidence Interval (95% CI): 0.41–0.61)) and 3rd SMI tertile had 50% and 76% (OR: 0.24, 95% CI: 0.19–0.29) lower likelihood to have NAFL compared with their 1st tertile counterparts. This association remained robust after multiple adjustments; however, significance was marginally lost, when waist circumference was added to the model. Subsequently, a multi-adjusted dose-response analysis between SMI and NAFL was performed in the total sample, as well as in the subcategories of normal and abnormal waist circumference. In the total sample, a significant inverse association between SMI and NAFL was observed [OR (per 2 points increase in SMI) = 0.94 (95% CI: 0.92–0.95); p=0.001]. When categorized by waist circumference, participants with moderate/high SMI and normal waist circumference had the lowest NAFL rates (24.3%). Those with low SMI and normal waist circumference and those with moderate/high SMI and abnormal waist circumference had similar rates of NAFL (47.4% and 50.3%, respectively; p=0.25). Participants with both low SMI and abnormal waist circumference presented the highest NAFL rate (60.5%), which was significantly higher compared with the rest subgroups (p<0.001). These findings were confirmed in multi-adjusted analysis to assess NAFL odds per case: participants with adnormal waist, [OR (per 2 points increase in SMI) = 0.97 (95% CI: 0.94–1.00)] vs. participants with normal waist [OR (per 2 points increase in SMI) = 0.89 (95% CI: 0.84–0.95)].
Conclusions
Increasing SMI was associated with lower rates of NAFL independently to abdominal obesity, whereas the two interact as key determinants of NAFL.

Abstract
BACKGROUND The aging of global population has increased the scientific interest in the concept of healthy aging and its determinants. AIM The aim of this study was to investigate the association of sleep characteristics with trajectories of healthy aging. DESIGN AND SETTING Prospective observational study conducted in two cities, Maroussi and Larissa. PARTICIPANTS A total of 1226 older adults (≥65 years, 704 women) were selected through random sampling. MEASUREMENTS Sleep quality was assessed with the Sleep Index II, and sleep duration was self-reported. A healthy aging metric was introduced using an Item Response Theory approach based on validated questionnaires that assessed functionality. Four healthy aging trajectories were developed based on whether the healthy aging status of the participants was above (High) or below (Low) the median at baseline and follow-up, i.e., High-High, High-Low, Low-High, and Low-Low. The association of sleep characteristics with the trajectories was investigated using a multinomial logistic regression with the Low-Low group as reference, adjusting for potential confounders. RESULTS 34.3% participants classified to the High-High group, 15.7% to the High-Low, 18.6% to the Low-High, and 31.4% to the Low-Low group. Better sleep quality was associated with the probability of belonging to the High-High group (p-value<0.001); while, long sleep duration was inversely associated with likelihood of being classified in the High-High group (p-value < 0.05). CONCLUSION Poor sleep quality and long sleep duration seem to have a significant negative association with healthy aging. Public health policies are needed to raise awareness about the importance of sleep characteristics on human health.

Abstract
Abstract
Background/Introduction
Although cardiovascular disease (CVD) guidelines emphasize consuming minimally processed foods, such as fruits, vegetables, whole grain products, nuts and seeds, less attention has been given to the importance of minimizing ultra-processed foods, probably due to the paucity of studies that exist.
Purpose
The aim of the present work was to investigate the association between the consumption of ultra-processed foods and ten-year first fatal/non fatal CVD event in a sample from Greece.
Methods
A prospective study was conducted during 2001–2012 studying n=1,514 men and n=1,528 women (>18 years old) free of CVD. Baseline dietary assessment was based on a validated semi-quantitative food frequency questionnaire. Ultra-processed foods were defined according to a standardized procedure and included among others sweets and desserts, beverages, salty snacks, breakfast cereals and fast foods. Follow-up assessment of first fatal/non fatal CVD event (2011–2012) was achieved in n=2,020 participants (n=317 cases). Cox proportional hazards models were constructed to determine the multiadjusted association between ultra-processed food intake (energy-adjusted servings per week) and incident fatal/non fatal CVD.
Results
On average, participants consumed about 15 servings of ultra-processed foods per week. Ranking from 1st to 3rd ultra-processed food consumption tertile (low to high level of intake) CVD incidence was 8.1%, 12.2%, 16.6% (p=0.006). Each additional weekly serving of ultra-processed food was associated with 10% higher CVD risk within the decade (Hazard Ratio (HR)=1.10, 95% Confidence Interval (95% CI) (1.02, 1.21), p=0.04). This association was reexamined according to participants' level of adherence to a cardiac friendly dietary pattern i.e. Mediterranean diet (defined through MedDietScore, range 1–55). In particular, the aggravating effect of ultra-processed foods was retained and only slightly attenuated even in the subset of participants with moderate to high level of adherence to Mediterranean diet (defined as MedDietScore>27) (HRper 1 serving/week=1.08, 95% CI (0.98, 1.19), p=0.09). On the other side, it became even stronger in case of low level of adherence to this pattern (HRper 1 serving/week=1.19, 95% CI (1.12, 1.25), p=0.02).
Conclusions
Current findings support that even in a population with Mediterranean origins and easy access to healthy least processed choices, systematic consumption of ultra-processed foods on a weekly basis was associated with increased risk of hard CVD events. Tailor-made public health initiatives and nutrition policies are demanded to promote healthy and sustainable dietary patterns with less-processed foods of high nutritional value.

Abstract
Abstract
Background/Introduction
Some plant-based diets like the Mediterranean diet have been suggested to have a beneficial impact on liver disease. However, the quality of plant-based diets – in general – varies.
Purpose
The association between plant-based diet indices and non-alcoholic fatty liver disease (NAFLD) as well as their interaction on ten-year cardiovascular disease incidence was examined.
Methods
A prospective study was conducted during 2001–2012 studying n=1,514 males and n=1,528 females (aged >18 years old) free of CVD. Healthy metabolic status was defines as absence of all NCEP ATP III (2005) metabolic syndrome components (excluding waist circumference). Follow-up CVD assessment (2011–2012) was achieved in n=2,020 participants (n=317 cases). Overall, healthful and unhealthful plant-based dietary indices (PDI, hPDI and uPDI) were created through a standard procedure; hPDI was principally characterized by increased consumption of fruits/vegetables, whole grains, nuts, legumes, oils, tea/coffee while uPDI was related with increased intake of juices, sweetened beverages, refined grains, potatoes and sweets. NAFLD was defined according to validated liver steatosis indices.
Results
In total, n=707 (35%) participants presented NAFLD at baseline. Ranking from 1st to 3rd PDI tertile, NAFLD prevalence was 40.3%, 35.6% and 30.9%, respectively (p=0.04). Multiadjusted analysis revealed significant inverse associations between PDI and NAFLD prevalence [Odds Ratio (OR) (3rd vs. 1st tertile)=0.60 95% Confidence Interval (95% CI) (0.35, 0.92)] as well as hPDI [OR (3rd vs. 1st tertile) = 0.75 95% CI (0.64, 0.89)]. On the other side, increased uPDI had a positive association with NAFLD prevalence [OR (3rd vs. 1st hPDI tertile) = 1.22 95% CI (1.05, 1.34)]. NAFLD predicted CVD in multi-adjusted model [Hazard Ratio (HR) = 1.35, 95% CI (1.08, 2.10)]. Subgroup analyses according to participants' adherence to overall, healthy and unhealthy plant-based patterns revealed that this observation remained significant in the following cases: participants in the 1st PDI tertile, [HR=1.40, 95% CI (1.15, 2.09)] and participants in the 1st hPDI tertile [HR=1.47, 95% CI (1.22, 2.12)].
Conclusions
Lower adherence to plant-based diet was associated with substantially higher long-term CVD risk for a NAFLD individual. Most importantly, the healthy or unhealthy food choices within this pattern seemed to determine liver steatosis progression and in turn cardiometabolic health.

Abstract
Abstract
Background/Introduction
The role of dietary protein on cardiometabolic health remains complex influenced by concomitant changes in overall diet composition. The quality of protein sources is currently suggested as more detrimental than the level of consumption itself.
Purpose
The association between different protein-rich dietary patterns and 10-year transition to metabolically unhealthy status in a sample from Greece was evaluated.
Methods
A prospective study was conducted during 2001–2012 studying n=1,514 men and n=1,528 women (>18 years old) free of CVD. Healthy metabolic status was defined as absence of all NCEP ATP III (2005) metabolic syndrome components. Baseline dietary assessment was based on a validated semi-quantitative food frequency questionnaire. Dietary protein was calculated through standardized food database. Follow-up cardiometabolic assessment (2011–2012) was achieved in n=2,020 participants. Protein-rich dietary patterns were derived through factor analysis in the subsample of participants with high daily protein intake (>15% of total energy intake corresponding to the median consumption level). Patterns were named according to food scores that correlated most with the factor (scores>0.5).
Results
Overall, six of ten participants lost their metabolically healthy status within a decade. Multiadjusted analysis revealed an inverse yet non-significant association between total energy-standardized protein intake and transition to metabolically unhealthy status [Odds ratio (OR) (high vs. low protein intake)=0.59, 95% Confidence Interval (95% CI) (0.32, 1.10), p=0.09]. Factor analysis extracted three protein-rich dietary patterns, explained 55% of the total variation in intake. Factor A was characterized by increased consumption of processed meet, unprocessed red meat and eggs, factor B was characterized by increased consumption of nuts and seeds, legumes, whole grain products and fish while factor C was characterized by increased consumption of dairy products, poultry and vegetables. Multiadjusted logistic regression analysis revealed that factor B had the strongest protective effect against 10-year transition to metabolically unhealthy status [ORper 1 point increase in factor B score=0.74, 95% CI (0.60, 0.85), p=0.01] followed by a marginally protective effect of factor C [ORper 1 point increase in factor C score=0.89, 95% CI (0.73, 1.05), p=0.07]. Participants with higher adherence to factor A had an increased likelihood to lose their metabolically healthy status [ORper 1 point increase in factor A score=1.15, 95% CI (1.02, 1.30), p=0.04].
Conclusions
The present work confirms that within an increased level of dietary protein intake, different cardiometabolic outcomes were observed according to the quality of protein food sources consumed.

Abstract
Abstract
Background/Introduction
Inclusion of non-alcoholic fatty liver disease (NAFLD) as a component of metabolic syndrome (MetS) and/or a criterion for defining metabolically healthy vs. unhealthy obese (MHO vs MUO) status remains to be decided.
Purpose
The present work evaluated the role of NAFLD at baseline in the transition of MHO to MUO status, and its role in predicting cardiovascular disease (CVD) incidence ten years later.
Methods
A prospective longitudinal study was performed between 2001 and 2012 studying 1,514 (49·8%) men and 1,528 (50.2%) women (>18 years old) free of CVD at baseline and residing in the greater Athens area, Greece. Follow-up assessment of first fatal/non fatal CVD event (2011–2012) was achieved in n=2,020 participants (n=317 cases). Healthy metabolic status was defined as absence of all NCEP ATP III (2005) metabolic syndrome components. NAFLD was defined according to validated liver steatosis indices.
Results
Among obese participants, MHO prevalence was 9.8% (n=277). Only half of the MHO subjects retained their metabolically healthy status one decade later. NAFLD was an important predictor of this transition; MHO participants with NAFLD at baseline had about two times higher odds to develop unhealthy metabolic status compared with their non-NAFLD counterparts. Subsequently, MHO status accompanied by NAFLD was associated with increased CVD risk (Hazard Ratio=2.90 95%Confidence Interval (1.35, 5.40)) in contrast to their non-NAFLD MHO counterparts. C-statistics revealed that NAFLD significantly increased the discriminative ability of the standardly defined metabolic status (p for C-index change=0.002), yet in the total sample its contribution to the model seemed to be similar with the common metric of central obesity i.e. waist circumference (CNAFLD=0.711 vs. Cwc=0.710). When the analysis was restricted to the obese subset, it was revealed that the discriminative ability of the model adjusted for NAFLD was significantly higher compared with the one adjusted for waist circumference (CNAFLD=0.719 vs. Cwc=0.702).
Conclusions
Taking under consideration NAFLD – via validated indices – in the clinical assessment of an apparently healthy obese individual contributes to better defining future risk of conversion to metabolically unhealthy obesity and future cardiometabolic risk.

Abstract
We evaluated the role of a Mediterranean-style diet in preventing acute coronary syndromes [ACS]. Data from CARDIO2000, a multi-centre retrospective case-control study investigating the association between ACS and demographic, nutritional, lifestyle and medical risk factors were used. We studied 661 patients hospitalized for a first ACS event and 661 matched controls without clinical suspicion of cardiovascular disease. The Mediterranean diet significantly reduced [by 16%] the risk of developing ACS. The association remained significant in the presence of hypertension, hypercholesterolaemia, sedentary lifestyle, diabetes mellitus or a combination of two of these cardiovascular risk factors. Our findings illustrate the importance of the Mediterranean diet in the primary prevention of acute coronary events

Background/Introduction: Among all behaviors, nutrition makes the largest contribution to cardiovascular disease (CVD) morbidity across Europe. Purpose: The aim of the present work was to quantify the changes in 10-year CVD onset or recurrence or mortality, in relation to transitioning from low to higher level of adherence to Mediterranean diet. Methods: An individual-level microsimulation was created based on ATTICA (2002-2012, n = 3042 subjects free-of-CVD) and GREECS (2004-2014, n = 2172 patients with acute coronary syndrome (ACS)) studies (in total n = 5214). Eight scenarios regarding the proportion of participants and the size of improvement of level of adherence to Mediterranean diet were compared in terms of relative change in CVD incidence and mortality, as well as, the number of preventable CVD events and deaths. Results: Improving the level of adherence to the Mediterranean diet, even in 10% of the population, a significant relative percentage reduction was observed in the 10-year risk for CVD onset, recurrence and mortality, with the observed reductions being higher among women. In particular, at least 851 first CVD events, 374 recurrent CVD events and 205 CVD deaths per 100,000 of population could be averted or delayed. Additionally, Mediterranean diet clustering revealed that high consumption of fruits, vegetables, whole wheat products and legumes was more important than low consumption of meat and full fat dairy products against CVD. Conclusion: This microsimulation process confirms the added value of Mediterranean diet in primary and secondary CVD prevention having great achievements even with small modifications on a population basis, while challenges the orientation of a Mediterranean-diet intervention giving higher weights to plant-based part.

Background/Introduction: Consistent evidence exists for a causal association between blood cholesterol and cardiovascular disease (CVD) yet alternative lipid markers are still discussed. To this issue, non-High Density Lipoprotein (non-HDL) cholesterol offers a simple way to analyze the total amount of pro-atherogenic lipoproteins containing apolipoprotein B100. Purpose: The aim of the present work was to evaluate the 10-year first fatal/non fatal CVD incidence related to non-HDL cholesterol on the basis of existing thresholds suggested by the European Society of Cardiology (ESC) in a sample with prevalent CVD. Methods: ATTICA study was conducted during 2001-2012 including n = 1,514 men and n = 1,528 women (aged >18 years old) from the greater Athens area, Greece. Baseline serum blood lipids profile was measured. Non-HDL cholesterol was evaluated according to the formula "total cholesterol minus HDL cholesterol" and the following categories were used: <100 mg/dL; 100 to <145 mg/dL; 145 to <185 mg/dL; 185 to <220 mg/dL, and ≥220 mg/dL. Ten-year follow up was performed (2011-12) in 2,020 participants (n = 317 cases, man-to-woman CVD incidence ratio = 1.66). Results: About 42% of women had non-HDL values within the range of 100 to <145 mg/dL while in case of men about one third of them had non-HDL values within the range of 100 to 185mg/dL. Ranking from low to high non-HDL cholesterol CVD incidence was 5.3%, 13.3%, 18.0%, 20.0% and 28.9%. The man-to-woman age-standardized CVD incidence ratio was 1.50, 1.93, 1.37, 1.24, 1.64, respectively; indicating a steep rise in CVD incidence rate in favor of men when non-HDL cholesterol levels reached the 2nd category levels (i.e. 100 to <145 mg/dL) while women seemed to present CVD incidence rates closer to their men counterparts in case of higher non-HDL cholesterol values (i.e. 145 to <220 mg/dL). Multi-adjusted Cox regression analysis revealed that 30mg/dL increase in non-HDL cholesterol values corresponded to 34% higher risk to develop CVD within the decade (Hazard ratio (HR)=1.34, 95% Confidence Interval (95%CI) (1.00, 1.81)). The association remained significant only in case of men (p for gender interaction = 0.01); HR = 1.45, 95%CI (1.09, 1.95). Additionally, when the categorical non-HDL variable was used, its independent aggravating effect on CVD outcome reached the level of significance only for non-HDL cholesterol values >220mg/dL; HR5th vs. 1st category = 1.95, 95%CI (1.10, 4.30). Sex-based stratified analysis revealed significance only in men and particularly HR5th vs. 1st category = 3.14, 95%CI (1.26, 5.10). In case of women the aggravating effect was retained yet without reaching the level of significance. Conclusion: Even if non-HDL cholesterol concentrations in blood are strongly associated with long-term risk of atherosclerotic CVD, its use in daily clinical practice is challenged. These outcomes could be useful for physician–patient communication about primary prevention strategies.

Abstract
BACKGROUND AND AIMS We assessed the association of Mediterranean diet with NAFLD and their interaction in predicting ten-year diabetes onset and first fatal/non-fatal cardiovascular disease (CVD) incidence. METHODS The ATTICA prospective observational study in Athens, Greece included 1,514 men and 1,528 women (>18 years old) free-of-CVD at baseline. Liver steatosis and fibrosis indices were calculated. Mediterranean diet adherence was assessed through MedDietScore. At the ten-year follow-up visit, CVD evaluation was performed in an a priori specified subgroup of n = 2,020 participants and diabetes onset in n = 1,485 free-of-diabetes participants. RESULTS MedDietScore was inversely associated with steatosis and fibrosis; e.g. in the case of the TyG index the Odds Ratio (OR) of the 3rd vs. 1st MedDietScore tertile was = 0·53, [95% Confidence Interval (95% CI) (0·29, 0·95)] and the associations persisted in multi-adjusted models. NAFLD predicted incident diabetes prospectively over a ten year period [HR = 1·87, 95% CI (0·75, 4·61)] and the association remained significant only in subjects with low MedDietScore (below median) whereas diabetes onset among subjects with higher MedDietScore was not influenced by NAFLD. Similarly, NAFLD predicted CVD [Hazard Ratio (HR) = 3·01, 95%CI(2·28, 3·95)]; the effect remained significant only in subjects with MedDietScore below median [HR = 1·38, 95% CI (1·00, 1·93)] whereas it was essentially null [HR = 1·00,95% CI (0·38, 2·63)] among subjects with higher score. Mediation analysis revealed that adiponectin and adiponectin-to-leptin ratio were the strongest mediators. CONCLUSIONS We report an inverse association between Mediterranean diet and NAFLD. Mediterranean diet protected against diabetes and CVD prospectively among subjects with NAFLD.

Abstract
Abstract
Background
DEpICT is an ongoing observational, cross-sectional study in community-dwellers in Limassol, Cyprus aiming to combine individual-level and community-level risk factors to decode their effect on arterial health (stiffness) as measured with pulse wave velocity (PWV).
Methods
Participants are >40 years who have been living in the same address for ≥5 years. They provide personal information on quality of life and mental health (SF-12 and GHQ-12), physical activity (IPAQ), adherence to Mediterranean diet (MedDiet) and sociodemographic. Anthropometric characteristics are measured on site, as well as arterial stiffness (carotid-femoral PWV) and central blood pressure. Neighborhood is self-assessed using the “Place Standard” Tool, as well as with an independent neighborhood audit using the newly-developed CyNoTes tool.
Results
Out of the first 176 participants (53% male), 45% had a college/university degree with a further 19% having graduate degrees, while the vast majority (92%) reported home ownership. Education was not associated with net family income (p = 0.3) nor home-ownership (p = 0.28). Out of the 14 constructs in Place standard, “Public transport” and “Participation and sense of control” were rated lowest (3.1 ± 1.9 and 3.1 ± 1.8) and “Identity and sense of belonging” and “Safety” highest (4.1 ± 1.9 and 4.5 ± 1.8). Education was not associated with any construct in “Place” or with total neighbourhood score.
Conclusions
Participants rate the social and safety aspects of their neighbourhood higher than the build aspects. Educational attainment may not be a good proxy for neighbourhood socioeconomic assessment in Cyprus, given the high rates of university graduates.
Key messages
Participants express the need for more public engagement in community decision-making; sense of lacking control may affect individual health. Educational attainment is not a good proxy for neighborhood socioeconomic assessment in the cultural context of Cyprus.

Abstract
Abstract
Background/Introduction
Brain and heart interplay is highly discussed in healthy yet even more in cardiac population with inconclusive evidence regarding the sex-related interactions.
Purpose
The sex-specific effect of depressive symptomatology (DS) on 10-year first and recurrent cardiovascular disease (CVD) events was evaluated.
Methods
The samples of two cohorts were used; n=845 free of CVD males and females (2002–2012) and n=2,172 males and females with acute coronary syndrome (ACS) (2004–2014) with baseline psychological assessments (Zung Self-Rating Depression Scale and Centre of Epidemiological Studies-Depressive symptoms scale, respectively) were used. The percentage of excess mediated risk (PEMR) and the corresponding 95% Confidence Interval (95% CI) were used to evaluate the mediating effect of various factors on the examined association.
Results
ACS as well as free-of-CVD females scored significantly higher for DS. Males exceeded females against first (19.7% vs. 11.7%, p<0.001) and subsequent CVD events (38.8% vs. 32.9%, p=0.016) while in participants with DS a male-to-female first and recurrent CVD event rate ratio below -1- was noticed. Multivariate Cox regression analysis revealed that DS remained an independent aggravating factor for first (Hazard Ratio (HR) = 2.72, 95% Confidence Interval (95% CI) 1.50, 9.12, p=0.01) and recurrent (HR=1.31, 95% CI 1.01, 1.69, p<0.001) CVD events only in females. Mediation analysis in females revealed that 35% (23%, 44%) of excess first-CVD-event risk of DS was attributed to lifestyle, sociodemographic, clinical, anthropometric factors as well as lipid and inflammatory markers. The respective number for recurrent events was 46% (23%, 53%). In free-of-CVD females, factors mostly accounted for excess DS risk, close to the overall, were C-reactive protein [38% (31%, 51%)], waist-to-hip ratio [35% (31%, 42%)] and diabetes [32% (27%, 36%)]. Among lipid markers, the biggest mediating effect was observed for high density lipoprotein [28% (25%, 32%)] and triglycerides [26% (22%, 33%)]. As for non-clinical factors, financial status [23% (15%, 31%)] presented the biggest mediating effect followed by educational status, adherence to Mediterranean diet and sleep duration. In ACS females, diabetes [40% (27%, 51%)] and adherence to medication [40% (29%, 53%)] had the biggest mediating effect followed by hypertension [38% (27%, 48%)]. Patients' CVD history and discharge status, presented a very low mediating effect size (∼10%). Among the examined lifestyle factors, current smoking was revealed the strongest mediator, accounting for 33% (19%, 39%) of DS aggravating effect. Anthropometric parameters in terms of body mass index seemed to modestly mediate the examined association (∼29%).
Conclusions
The present work augments prior evidence that psychological stressors possess important drivers of CVD onset and progression mainly in females while it gives rise to research towards unidentified paths behind this claim.

Abstract
Abstract
Background/Introduction
The notion that standard weight–height tables are the proper way to determine high-risk groups for obesity-related disorders has been largely challenged, yet scarce data exist from the standpoint of sex.
Purpose
To evaluate the effect of combined weight and waist-circumference (WC) status on 10-year first fatal/non fatal cardiovascular disease (CVD) event in apparently healthy males and females.
Methods
A prospective study (2001–2012) was conducted in Greece with n=1,514 males and n=1,528 females (aged >18 years old) free of CVD. Follow-up assessment of CVD event (2011–2012) was achieved in n=2,020 participants (317 cases). Normal weight (NW) status was defined as body mass index (BMI) from 18.5kg/m2 to 25kg/m2 while central obesity as WC≥102cm for males and ≥88cm for females. NW central obesity (NWO) was defined as BMI within the normal range and abnormal WC.
Results
The prevalence of NWO reached 10% (n=302) with female:male ratio being close to 4:1 (p<0.001). Within NW group ∼25% of participants presented increased WC. Ten-year CVD incidence in NWO subjects reached 14.1% which was twice as high as the respective rate for NW participants without central obesity (7.4%) and followed by the 15.4% and 24.1% in overweight/obese participants without or with central obesity, respectively (p<0.001). The female:male CVD event rate ratio was 0.37, 0.77, 0.42, 0.64 ranking from NW participants without central obesity to NWO and overweight/obese without or with central obesity (p<0.001). Cox regression analysis revealed that NWO status was independently associated with 10-year CVD event (Hazard Ratio (HR)=1.87, 95% Confidence Interval (95% CI) 1.04, 3.37, p=0.03) when compared with their NW counterparts with normal WC, after adjusting for sociodemographic, clinical, lifestyle and biochemical factors (i.e. insulin resistance and systemic inflammation). When NWO subjects were set as reference group and compared with their overweight/obese counterparts with or without central obesity, no significant trends were observed (all ps>0.05). A significant interaction between sex and the combined weight and central obesity status was observed (p for interaction<0.001). Stratified analysis revealed that the aforementioned associations were retained only in NWO females (HR=2.35, 95% CI 1.15, 4.79, p=0.01) when compared with their NW counterparts without central obesity; in males the association did not reach the level of significance. C-statistics [C-index (95% CI)] revealed that within the NW range, WC-adjusted model had a better discriminative ability in females [0.810 (0.778, 0.842)] compared with males [0.789 (0.763, 0.810)] while a BMI-adjusted model seemed to discriminate better the CVD event in males [0.801 (0.772, 0.831)] than in females [0.762 (0.731, 0.798)].
Conclusion
Studies addressing the complex interaction between fat and BMI as well as its effect on CVD are demanded, yet with the potential to highlight sex-specific remarks.

Abstract
Abstract
Background/Introduction
Metabolically healthy obesity (MHO) status has been recently conferred to be a transient condition with cohorts revealing that a considerable proportion, from 33% to 52%, lose their status over time.
Purpose
To evaluate the stability of MHO, its effect on 10-year first fatal/non fatal CVD onset and the mediating effect of adiponectin.
Methods
A prospective study was conducted during 2001–2012 studying n=1,514 males and n=1,528 females (aged >18 years old) free of CVD. Follow-up CVD assessment (2011–2012) was achieved in n=2,020 participants; of them, n=317 incident cases were identified. Obesity was defined as body mass index≥30kg/m2 and healthy metabolic status as absence of all NCEP ATP III (2005) metabolic syndrome components (excluding waist circumference). Circulating adiponectin level was measured at baseline (4.0 (2.0) μg/mL).
Results
MHO prevalence reached 4.8% (n=146) (4.9% in males and 4.7% in females, p=0.198). 28.2% of obese participants presented a metabolically benign status at baseline. In the 5-year follow-up period, transition to metabolically unhealthy status was observed for 33% of MHO participants. Within the decade, almost half of MHO participants resulted as metabolically unhealthy obese. Unadjusted analysis revealed that stable vs. temporal MHO subjects had better lifestyle (i.e. higher adherence to Mediterranean diet and better physical activity status) at the recruitment (all ps<0.05). Temporal MHO subjects presented lower adiponectin values (2.8 (1.1) μg/mL) compared with their stable MHO counterparts (4.1 (1.9) μg/mL) (p<0.05). Multivariate Cox regression analysis revealed no significant discrepancies on 10-year CVD risk between MHO and metabolically healthy non-obese subjects (Hazard Ratio (HR)=0.95, 95% Confidence Interval (95% CI) 0.37, 2.08, p=0.32). Only the subset of temporal MHO subjects reached the level of significance (HR=1.43, 95% CI 1.02, 2.01, p=0.04). Stable MHO status was not independently associated with 10-year CVD risk (p>0.05). Low vs. high adiponectin level was associated with ∼1.3 times higher 10-year risk to move from MHO to metabolically unhealthy obesity status (HR=1.33 95% CI 1.10, 4.02). Sensitivity analyses revealed that adiponectin had a significant interacting effect on the examined associations (p for interaction=0.01); stratified analysis using the mean value of adiponectin to define the strata revealed that MHO (stable or temporal) status was positively associated with 10-year CVD event only in participants with low adiponectin levels i.e. below the mean value of 4.1 μg/mL (HR=1.45 95% CI 1.19, 3.68).
Conclusions
Weight management is needed to prevent cardiometabolic features even in participants with increased weight status with healthy metabolic status. It is noteworthy that adiponectin may be an underlying path of the stability and CVD risk corresponding to this intermediate condition probably related with insulin resistance and other relevant paths.

Abstract
Abstract
Background/Introduction
In the context of novel risk factors in cardiovascular disease (CVD) spectrum, lipoprotein (a) (Lp(a)) is a highly discussed biomarker with promising evidence.
Purpose
The association between Lp(a) and 10-year first fatal/non fatal CVD event in free of CVD males and females was evaluated.
Methods
A longitudinal prospective study was conducted during 2001–2012, studying 1,514 males and 1,528 females (aged >18 years old). Follow-up assessment of CVD (2011–2012) was achieved in n=2,020 participants (n=317 cases). Of them, baseline Lp(a) was measured in n=1,890 participants. The recommended threshold of 50mg/dL was used to define abnormal Lp(a) status (≥50mg/dL). Effect-size of Lp(a) on CVD was evaluated through Cox-regression analysis while its discrimination ability through C-statistics.
Results
Ten-year CVD event rate was 14% and 24% in participants with Lp(a)<50 mg/dL and Lp(a)≥50 mg/dL, respectively (p=0.05). In multivariate analysis those with Lp(a)≥50 mg/dL had two times higher risk to develop CVD compared with participants with normal Lp(a) (Hazard Ratio (HR)=2.18, 95% Confidence Interval (95% CI) 1.11, 4.28, p=0.04). Sex-based stratified analysis revealed that the independent Lp(a)-effect on CVD was retained only in males (HR=2.00, 95% CI 1.19, 2.56, p=0.05); while in females significance was lost when adjusting for low and high density lipoprotein (LDL-C, HDL-C), triglycerides and statins use (p for sex interaction=0.01). Sensitivity analyses revealed that Lp(a) significantly increased CVD risk only in case of abnormal HDL-C, apolipoprotein A1 and triglycerides; interestingly, the interaction between these lipid markers, sex and Lp(a) was significant (p for interaction=0.001) implying that this observation could be sex-mediated. C-indexes and correct classification rates of a standard model with three different levels of adjustment (i.e. Lp(a) or conventional lipid markers or combined lipid markers) were evaluated per sex. In females, the highest total correct classification rate was higher in model adjusted for conventional lipid markers (89.6%) with the rate corresponding to CVD cases being more than twice as high in Lp(a)-adjusted model (19.6% vs. 8.5%) and lower than in fully adjusted model (15.7%). A similar ranking was observed in case of C-indexes (0.831 vs. 0.820 vs. 0.829). Males presented the best total correct classification rate in fully adjusted model (96.5%). Case-related correct classification rate was about 3 times higher in Lp(a)-adjusted model compared with the respective rate in females (24.7% vs. 8.5%). C-index after Lp(a) adjustment in the model with conventional lipid markers increased by 0.01 (i.e. 0.772 vs. 0.784).
Conclusion
While ever increasing efforts have sought to elucidate Lp(a) as a therapeutic target or risk-prediction biomarker in CVD prevention clinical recommendations remain to be guided with appropriate conclusive evidence, mostly from a sex-centered standpoint.

Abstract
BACKGROUND AND AIMS Predictive and prognostic ability of muscle mass in CVD settings is increasingly discussed. The gender-specific effect of skeletal muscle mass index (SMI) on 10-year recurrent fatal/non fatal cardiovascular disease (CVD) event of acute coronary syndrome (ACS) patients was evaluated. METHODS AND RESULTS In 2006-2009, n = 1000 consecutive patients (n = 222 women), hospitalized at the First Cardiology Clinic of Athens with ACS diagnosis and with symptoms and left ventricular function indicative of heart failure were selected. SMI was created to reflect skeletal muscle mass through appendicular skeletal muscle mass (indirectly calculated through population formulas) divided by body mass index (BMI). In the 10-year follow-up (2016), 55% of ACS patients experienced recurrent fatal/non fatal CVD events (53% in women vs.62% in men, p = 0.04). Patients in the 2nd SMI tertile (mostly overweight) had 10% lower risk for CVD recurrence (women:men rate ratio = 0.87) over their counterparts in the 1st (mostly normalweight) and 3rd tertile (mostly obese). Multivariate analysis revealed that ACS patients in the 2nd SMI tertile presented 46% and 85% lower CVD event risk over their counterparts in the 1st tertile (Hazard Ratio (HR) = 0.54, 95% Confidence Interval (95% CI) 0.30, 0.96, p = 0.002) and 3rd tertile (HR = 1.85, 95%CI 1.05, 2.94, p = 0.03). Gender-based analysis revealed that this trend remained significant only in women. Inflammatory markers had strong confounding effect. CONCLUSION A U-shape association between SMI and 10-year CVD event especially in women was highlighted. This work reveals gender-specific remarks for "obesity-lean paradox" in secondary prevention, implying that high muscle mass accompanied by obesity and excess adiposity may not guarantee better prognosis.

Abstract
BACKGROUND AND AIM The aim of the present review is to examine evidence from published studies on the effectiveness of six or more months of low carbohydrate, macrobiotic, vegan, vegetarian, Mediterranean and intermittent fasting (IF) diets compared to low fat diets on diabetes control and management. METHODS AND RESULTS In accordance with PRISMA guidelines, Cochrane CENTRAL, PubMed and Scopus databases were systematically searched for relevant studies. Twenty randomised controlled trials (RCTs) > 6 months that investigated the effectiveness of various dietary patterns on type 2 diabetes mellitus (T2DM) were included. Risk of bias was assessed using the Cochrane tool. There were no significant differences in glycemic control, weight and lipids for the majority of low carbohydrate diets (LCDs) compared to low fat diets (LFDs). Four out of fifteen LCD interventions showed better glycemic control while weight loss was greater in one study. The Mediterranean dietary pattern demonstrated greater reduction in body weight and HbA1c levels and delayed requirement for diabetes medications. The vegan and macrobiotic diet demonstrated improved glycemic control, while the vegetarian diet showed greater body weight reduction and insulin sensitivity. CONCLUSIONS Although more long-term intervention trials are required, mounting evidence supports the view that vegan, vegetarian and Mediterranean dietary patterns should be implemented in public health strategies, in order to better control glycemic markers in individuals with T2DM.

Abstract
BACKGROUND The present study aimed to examine how different meal and snack patterns are associated with micronutrient intakes and diet quality among a nationally representative sample of Greek children and adolescents aged 1-19 years from the cross-sectional Hellenic National Nutrition and Health Survey (n = 598). METHODS Meal and snack patterns were derived using 24-h dietary recalls. Mean adequacy ratio (MAR) was used as an overall measure of diet quality. Multiple linear regression adjusted for covariates was conducted to examine associations between eating patterns, nutrient intakes and MAR. RESULTS Four most frequently reported eating schemes were identified including breakfast (B), lunch (L), dinner (D) and two snacks (S) (20.9%); B, L, D and 1S (16.2%); B, L, D and 3S (10.8%); and B, L and D (7.9%). Based on these schemes, the daily consumption of all main meals from the majority of the sample was highlighted. In children and adolescents aged 4-19 years, increasing snack frequency was positively associated with intakes of vitamin D, vitamin K, riboflavin, niacin, pantothenic acid, folate, magnesium, copper and selenium. An inverse association was recorded for vitamin E, vitamin B6 , calcium and iron. Among children aged 1-3 years, only niacin and copper were significantly associated with number of snacks, with the group of 'B-L-D-2S' presenting the highest intake. As for the overall diet quality, among all participants, there was no significant association of MAR with the type of meal and snack pattern, and thus the snack frequency. CONCLUSIONS Snacking behaviour is a common practice among children and adolescents. Modifying current snack foods with nutrient-rich choices could lead to an improvement of their diet's nutritional quality.

Abstract
Introduction The aim of the study is to present the most recent estimates of obesity (total and central) prevalence in Greek children and associated risk factors. Methods Population data are derived from a yearly, school-based health survey polled in 2015 on 336,014 (51% boys) children aged 4 to 17 years old from almost 40% of all schools of primary and secondary education in Greece. Anthropometric and physical fitness measurements were obtained by trained investigators. Dietary habits, physical activity status, sedentary activities and sleeping hours were assessed through self-completed questionnaires. The gender and age-specific Body Mass Index (BMI) cut-off points were used in order to define BMI groups. Results The prevalence of overweight and obesity in the whole population was 22.2% and 9.0% in boys and 21.6% and 7.5% in girls, respectively. Obesity presented decreasing trends in the transition from childhood to adolescence. Central obesity was diagnosed in 95.3% and 93.5% of the simple obese boys and girls, respectively, in almost two to three of overweight children (68.6% of boys and 64.3% of girls), and in 12% of normal weight children. Age, physical fitness, low adherence to Mediterranean diet, insufficient sleeping hours, inadequate physical activity levels and increased screen time were all associated with higher odds of total and central obesity. Conclusions Serious and urgent actions need to be taken from public health policy makers in order not only to prevent a further increase in obesity rates but, more important, to treat obesity and/or the obesity associated co-morbidities.

Abstract
BACKGROUND AND AIMS Visceral adiposity index (VAI) has been proposed as a marker of visceral adipose tissue accumulation/dysfunction. Our aim was to evaluate potential associations between the VAI and the 10-year cardiovascular disease (CVD) incidence. METHODS AND RESULTS During 2001-2002, 3042 Greek adults (1514 men; age: ≥18 years) without previous CVD were recruited into the ATTICA study, whilst the 10-year study follow-up was performed in 2011-2012, recording the fatal/non-fatal CVD incidence in 2020 (1010 men) participants. The baseline VAI scores for these participants were calculated based on anthropometric and lipid variables, while VAI tertiles were extracted for further analyses. During the study follow-up a total of 317 CVD events (15.7%) were observed. At baseline, the participants' age and the prevalence of hypertension, diabetes, hypercholesterolemia and metabolic syndrome increased significantly across the VAI tertiles. After adjusting for multiple confounders, VAI exhibited a significantly independent positive association with the 10-year CVD incidence (OR = 1.05, 95%CI: 1.01, 1.10), whereas the association of the body mass index (HR = 1.03, 95%CI: 0.99, 1.08), or the waist circumference (HR = 1.01, 95%CI: 0.99, 1.02) was less prominent. Sex-specific analysis further showed that VAI remained significantly predictive of CVD in men alone (HR = 1.06, 95%CI: 1.00, 1.11) but not in women (HR = 1.06, 95%CI: 0.96, 1.10). CONCLUSIONS Our findings show for the first time in a large-sample, long-term, prospective study in Europe that the VAI is independently associated with elevated 10-year CVD risk, particularly in men. This suggests that the VAI may be utilized as an additional indicator of long-term CVD risk for Caucasian/Mediterranean men without previous CVD.

Abstract
Objective The objective of this study was to examine the validity of EuroSCORE II in the Greek population. Methods A prospective single-center study was performed during November 1, 2013 and November 5, 2016; 621 patients undergoing cardiac surgery were enrolled. The EuroSCORE II values and the actual mortality of the patients were recorded in a special database. Calibration of the model was evaluated with the Hosmer-Lemeshow goodness-of-fit test, and discrimination with the areas under the receiver operating characteristic (ROC) curve. Results The observed in-hospital mortality rate was 3% (i.e. 18/621 patients). The median EuroSCORE II value was 1.3% (1st quartile: 0.86%, 3rd quartile: 2.46%), which indicates a low in-hospital mortality. Area under the ROC curve for EuroSCORE II was 0.85 (95% CI: 0.75-0.94), suggesting very good correct classification of the patients. Conclusion The findings of the present work suggest that EuroSCORE II is a very good predictor of in-hospital mortality after cardiac surgery, in our population and, therefore can safely be used for quality assurance and risk assessment.

Abstract
BACKGROUND/OBJECTIVES The aims of the study were as follows: (1) examine fluid intake and urinary hydration markers of children in Greece, (2) determine the calculated relative risk of hypohydration in children who did not meet the recommendations for daily water intake provided by the Institute of Medicine and the European Food Safety Authority compared with those who did and (3) analyze the efficacy of the recommendations as a method to achieve euhydration in children. SUBJECTS/METHODS One hundred and fifty Greek boys and girls (age 9-13) recorded their fluid intake for 2 consecutive days. A 24-h urine collection was obtained during the second day. Fluid intake records were analyzed for total water intake from fluids (TWI-F), and urine samples were analyzed for osmolality, color, specific gravity and volume. Urine osmolality ⩾800 mmol/kg H2O was defined as hypohydration. RESULTS Water intake from fluids was 1729 (1555-1905) and 1550 (1406-1686) ml/d for boys and girls, respectively. Prevalence of hypohydration was 33% (44% of boys, 23% of girls). Children who failed to meet TWI-F recommendations demonstrated a risk of hypohydration that was 1.99-2.12 times higher than those who met recommendations (P⩽0.01). Boys between 9 and 13 years displayed urine osmolality of 777 (725-830) mmol/kg, and urine specific gravity of 1.021 (1.019-1.022), which was higher than those in girls between 9-13 years (P⩽0.015), and >27% were classified as hypohydrated despite meeting water intake recommendations. CONCLUSIONS Failure to meet TWI-F guidelines increased calculated relative risk of hypohydration in children. Boys between 9 and 13 years are at greater hazard regardless of meeting guidelines and may require greater water intake to avoid elevated urine concentration and ensure adequate hydration.

Abstract
BACKGROUND The present study aimed to investigate the association between gestational weight gain (GWG) and birth weight, as well as the body mass index (BMI) status, of children at the ages of 2 and 8 years. METHODS Population-based data were obtained from a database of all 7-9-year-old Greek children who attended primary school during 1997-2007. The study sample consisted of 5125 children matched with their mothers, randomly selected according to region and place of residence, and equally distributed (approximately 500 per year) throughout the study period (1997-2007). A standardised questionnaire was applied; telephone interviews were carried out to collect maternal age, BMI status at the beginning and the end of pregnancy and GWG, birth weight of offspring and BMI status at the ages of 2 and 8 years, as well as several other pregnancy characteristics (e.g. pregnancy duration, gestational medical problems, maternal smoking and alcohol consumption habits, and lactation of offspring after pregnancy). RESULTS Gestational weight gain was positively associated with the weight status of offspring at all three life stages studied: newborn (birth weight), infant (BMI) and child (BMI) [b = 0.008 (0.001), b = 0.053 (0.009) and b = 0.034 (0.007), respectively, all P < 0.001], after adjusting for maternal age at pregnancy (significant inverse predictor only at age 2 years). The same applied to excessive GWG, as defined by the Institute of Medicine guidelines. CONCLUSIONS Excessive GWG was associated with a higher risk of greater infant size at birth and a higher BMI status at the ages of 2 and 8 years. Healthcare providers should encourage women to limit their GWG to the range indicated by the current guidelines.

Abstract
According to American Diabetes Association "as many as 1 in 3 American adults will have diabetes by 2050" imposing a serious burden on healthcare services and highlighting a substantial need to reduce "new-cases" incidence. Diabetes is inextricably linked to diet, in the prevention-spectrum. Red-meat-intake has been positively associated with reduced glycemic control. However, divergence exists among meat subtypes (i.e. fresh and processed) and the magnitude of their impact on diabetes development. The present overview attempted to summarize the latest data regarding red-meat subtypes on the examined association. Four meta-analysis and 10 prospective studies, focusing on the role of fresh and processed red meat in diabetes prevention, were selected. All of studies highlighted the aggravating role of processed meat-products in diabetes incidence, while fresh meat reached significance in only half of them. Therefore, the contribution of fresh red meat on diabetes remains inconclusive. Valid conclusions seem more robust concerning processed-meat-consumption.

Abstract
BACKGROUND The present study evaluated the association between long-term, exclusive olive oil consumption, in cooking preparation or as a dressing, and the 10-year (2004-2014) incidence of acute coronary syndrome (ACS) among cardiac patients. METHODS From October 2003 to September 2004, a sample of 2172 ACS consecutive patients from six major Greek hospitals were enrolled. During 2013-2014, the 10-year follow-up was performed in 1918 patients (88% participation rate). The development of fatal or nonfatal ACS was recorded through medical records or hospital registries. Among other dietary components, added fats (i.e. olive oil, butter, margarine and seed oils) consumption at baseline examination was assessed using a semi-quantitative food frequency questionnaire. RESULTS Non-exclusive olive oil consumption on a daily basis was associated with an adverse effect on the ACS incidence after taking into account various potential confounders [odds ratio (OR) = 1.40, 95% confidence interval (CI) = 1.05-1.86, P = 0.024]. However, significant interactions between olive oil consumption and body mass index (BMI) (P = 0.082) and educational level (P = 0.054) led to further stratified analysis. Using BMI as strata (i.e. ≤29.9 versus >29.9 kg m(-2)), the above association remained significant only in obese patients (OR = 1.80, 95% CI = 1.03-3.12, P = 0.038), whereas, on examining the education status (i.e. ≤9 versus >9 years of school), a significant association was observed only among the higher educated patients (OR = 1.83, 95% CI = 1.01-3.32, P = 0.047). CONCLUSIONS Exclusive use of olive oil, either as a salad dressing or in cooking, should be promoted through the dietary management of ACS patients, with the aim of reducing the likelihood of recurrent cardiac episodes.

Abstract
AIMS To evaluate the influence of metabolic syndrome (MetS) as well as inflammatory and renal markers on cardiovascular disease (CVD) incidence. METHODS AND RESULTS During 2001-2002, 1514 men and 1528 women (>18 y) without any clinical evidence of CVD or any other chronic disease, at baseline, living in greater Athens area, Greece, were enrolled. In 2011-2012, the 10-year follow-up was performed in 2583 participants (15% of the participants were lost to follow-up). Incidence of fatal or non-fatal CVD was defined according to WHO-ICD-10 criteria. MetS was defined using three definitions, provided by the National Cholesterol Education Program Adult Treatment panel III (revised NCEP ATP III), the International Diabetes Federation (IDF) or the Harmonized definition. Furthermore, the contributory predictive role of C-reactive protein (CRP), inteleukin-6, uric acid and estimated glomerular filtration rate in the aforementioned models was evaluated. History of MetS-NCEP was positively associated with CVD, adjusting for potential confounding factors (OR:1.83, 95%CI:1.24-2.72). Not statistically significant associations with CVD incidence were observed when using the IDF or the Harmonized definition. Additionally, none of the added inflammatory and renal function markers mediated the influence of MetS on CVD incidence (all p's from Sobel test >0.40). C-statistic values for the MetS definitions used exceeded 0.789 (CI:0.751-0.827), indicating fair-to-good predictive probability of the models. CONCLUSION Results of the present work revealed the negative impact of MetS-NCEP, but not of the other MetS definitions, on CVD incidence, a key-point that may help in better understanding the role of IDF and Harmonized MetS definitions on CVD.

Abstract
BACKGROUND The purpose of this work was to investigate the links between oxidative stress, inflammation and coagulation and their effect on Mediterranean diet-diabetes relationship. METHODS In 2001-2002, a random sample of 1514 men (18-87 years old) and 1528 women (18-89 years old) was selected to participate in the ATTICA study, where Athens is the major metropolis. A validated questionnaire was used to assess lifestyle and dietary factors. Adherence to Mediterranean diet was recorded using MedDietScore. Among others, oxidative stress and inflammatory biomarkers were recorded. During 2011-2012, the 10-year follow-up was performed. Diabetes incidence was defined according to the American Diabetes Association criteria. RESULTS A total of 191 incident cases of diabetes were documented, yielding an incidence of 12.9% (13.4% in men and 12.4% in women). Medium and high adherence was found to decrease diabetes risk by 49% (95% CI: 0.30, 0.88) and 62% (95% CI: 0.16, 0.88), respectively, compared with low adherence. A logarithmic trend between Mediterranean diet and diabetes incidence was also revealed (p for trend = 0.042). Individuals with abnormal waist circumference (>94 for men, >80 for women) were benefited the most. Wholegrain cereals, fruits and legumes had the greatest predictive ability. The anti-diabetic effect of Mediterranean diet correlated with measurements of tumour necrosis factor-α, homocysteine and total antioxidant capacity. CONCLUSIONS The reported results support the role of Mediterranean diet as a promising dietary tool for the primary prevention of diabetes, by attenuating inflammation and fostering total antioxidant capacity. This dietary pattern may have therapeutic potential for many cardiometabolic disorders associated with inflammation and/or oxidative stress.

Abstract
BACKGROUND We sought to establish cross-sectional curves for body weight, height, body mass index (BMI), and waist circumference for 4- to 18-year-old Greek boys and girls, using the empirical distribution and the Lambda Mu and Sigma (LMS) statistical method. METHODS From March 2014 to May 2014, a total of 473,837 boys and girls aged 4 to 18 years who attended school in Greece were enrolled. The studied sample was representative, in terms of age-sex distribution and geographical region. Anthropometric indices measurements (i.e., height, weight and waist circumference) were performed and BMI was calculated and used to calculate normative values, using the percentiles of the empirical distributions and the LMS method. RESULTS Updated growth references for 4- to 18-year-old Greek children tabulated as critical percentiles and LMS values from 3 to 97 (P3, P10, P25, P50, P75, P90, P97) and smoothed curves are presented. Positive secular trends of height, weight and waist circumference were observed in children and adolescents 4 to 18 years old (all p values <0.001). At all ages, boys had higher anthropometric measurements than girls (all p values <0.01). Compared to 1998 data, mean height and weight were greater in 2014 for boys and girls at all ages. CONCLUSION Current national percentile curves for anthropometric indices could provide a more accurate estimation to assess physical growth in Greek children and adolescents.

Abstract
BACKGROUND AND AIMS A Mediterranean diet has been associated with lower all-cause and cardiovascular disease (CVD) morbidity and mortality, but the clinical and behavioral pathway has not been well understood and appreciated. The aim of this work was to explore the path between adherence to a Mediterranean-type diet, lifestyle behaviors, clinical status, and a 10-year incidence of CVD. METHODS AND RESULTS The ATTICA study was carried out in the Athens area during 2001-2002 and included 3042 participants free of CVD at baseline (49.8% men, aged 18-89). Adherence to a Mediterranean diet was assessed using the MedDietScore (range 0-55). During 2011-2012, 2583 out of the 3042 participants were found during the 10-year follow-up (15% lost to follow-up). Adherence to a Mediterranean diet decreased CVD risk (relative Risk (RR) per 1/55 unit = 0.96, 95% confidence interval (CI): 0.93, 1.00), independently of various sociodemographic, lifestyle, and clinical factors. Subgroup analyses revealed that participants with an unhealthy lifestyle (i.e., smokers, and obese and sedentary persons) remained protected from CVD through a greater adherence to a Mediterranean diet (RR for smokers = 0.92, 95%CI: 0.88, 0.97; RR for obese participants = 0.90, 95%CI: 0.82, 0.979; and RR for sedentary participants = 0.95, 95%CI: 0.90, 0.99). Path analysis revealed that adherence to a Mediterranean diet not only decreases the levels of C-reactive protein and interleukin-6 but also has an independent protective role against CVD risk per se (total effect of the MedDietScore on CVD = -0.003, 95%CI: -0.005 to 0.000). CONCLUSION Adherence to a Mediterranean diet confers a considerable reduction on CVD risk, independent of various factors. Therefore, even subjects with unhealthy lifestyle behaviors may benefit from adherence to this diet, suggesting another dimension to prevention strategies.

Abstract
AIM The purpose of this prospective study was to investigate the effect of alcohol consumption on the 10-year diabetes incidence. METHODS In 2001-2002, a random sample of 1514 men (18-89 years old) and 1528 women (18-87 years old) was selected to participate in the ATTICA study (Athens metropolitan area, Greece). Among various other characteristics, average daily alcohol intakes (abstention, low, moderate, high) and type of alcoholic drink were evaluated. Diabetes was defined according to American Diabetes Association criteria. During 2011-2012, the 10-year follow-up was performed. RESULTS The 10-year incidence of diabetes was 13.4% in men and 12.4% in women. After making various adjustments, those who consumed up to 1 glass/day of alcohol had a 53% lower diabetes risk (RR=0.47; 95% CI: 0.26, 0.83) compared with abstainers, while trend analysis revealed a significant U-shaped relationship between quantity of alcohol drunk and diabetes incidence (P<0.001 for trend). Specific types of drinks were not associated with diabetes incidence; however, a one-unit increase in ratio of wine/beer/vodka vs. other spirits was associated with an 89% lower risk of diabetes (RR=0.11; 95% CI: 0.02, 0.67). The protective effect of low alcohol consumption on diabetes incidence was more prominent among individuals with stricter adherence to the Mediterranean diet (RR=0.08; 95% CI: 0.011, 0.70) and without the metabolic syndrome (RR=0.34; 95% CI: 0.16, 0.70). CONCLUSION This work revealed the protective effect of modest alcohol consumption of particularly wine and beer against the long-term incidence of diabetes, possibly due to their pleiotropic health effects.

Abstract
The epidemiology of selenium (Se) is mainly based on the determination of total serum selenium levels (TSe) which by many aspects is an inadequate marker of Se status. In this study we applied a recently developed LC-ICP-MS method, for the determination of the selenium content of the three main serum selenium-containing proteins, in a subcohort of the ATTICA study. This enables us to investigate whether the selenium distribution to selenoproteins may correlate with demographic (age, gender) and lifestyle variables (smoking, physical activity) that are crucial for the development of chronic diseases. A sub-sample from the ATTICA Study, consisted of 236 males (40 ± 11 years) and 163 females (38 ± 12 years), was selected. The selenium content of glutathione peroxidase (GPx-3), selenoprotein P (SelP) and selenoalbumin (SeAlb) was determined in serum by LC-ICP/MS method. We found that 26% of TSe is found in GPx-3, 61% in SelP and 13% in SeAlb. We have assessed the different ratios of selenoproteins' selenium content (Se-GPX-3/Se-SelP, Se-GPX-3/Se-SeAlb, Se-SelP/Se-SeAlb), showing that people with similar TSe may have different distribution of this selenium to selenoproteins. Total selenium levels and gender are the variables that mostly affect selenium distribution to selenoproteins while age, smoking, physical activity and BMI do not significantly influence selenium distribution. In conclusion, the simultaneous determination of the selenium content of serum selenium-containing selenoproteins is necessary for a thorough estimation of selenium status. The ratio of the Se content between selenoproteins may be proven a novel, valid marker of selenium status.

Abstract
BACKGROUND The aim of this study was to evaluate the effect of high intensity, interval exercise on quality of life (QoL) and depression status, in chronic heart failure (CHF) patients. METHODS A randomized controlled trial (phase III). Of the 100 consecutive CHF patients (NYHA classes II-IV, ejection fraction ≤ 50%) that were randomly allocated to exercise intervention (n = 50, high-intensity intermittent endurance training 30 s at 100% of max workload, 30 s at rest, for 45 min/day-by-12 weeks) or no exercise advice (n = 50), 72 (exercise group, n = 33, 63 ± 9 years, 88% men, 70% ischemic CHF and control group, n = 39, 56 ± 11 years, 82% men, 70% ischemic CHF) completed the study. QoL was assessed using the validated and translated Minnesota Living with Heart Failure questionnaire. Depressive symptomatology was evaluated using the validated and translated Zung Depression Rating Scale (ZDRS). Maximal oxygen uptake (VO(2max)) and carbon dioxide production (VCO(2max)) were also measured breath-by-breath. RESULTS Data analysis demonstrated that in the intervention group MLHFQ score was reduced by 66% (P = 0.003); 6-min-walk distance increased by 13% (P < 0.05), VO(2max) level increased by 31% (P = 0.001), VCO(2max) level increased by 28% (P = 0.001) and peak power output increased by 25% (P = 0.001), as compared with the control group. CONCLUSION High intensity, systematic aerobic training, could be strongly encouraged in CHF patients, since it improves QoL, by favorably modifying their fitness level.

Abstract
BACKGROUND Cystatin C is a marker of renal function that appears to be associated with inflammation. The aim of the present study was to investigate whether there is any relationship between cystatin C, total and differential leukocyte count and other inflammatory markers. METHODS Cystatin C, creatinine, high sensitivity C-reactive protein (hs-CRP), haptoglobin, ferritin, serum albumin, glucose, total cholesterol, HDL and triglycerides together with total and differential leukocyte count were determined in 490 adults (46 ± 16 years, 40% men) who underwent a typical health examination. Glomerular filtration rate was estimated by the simplified Modification of Diet in Renal Disease formula. Anthropometric and lifestyle characteristics were also recorded. RESULTS After adjustment for demographic risk factors, comorbid health conditions and renal function, a positive and independent relationship of serum cystatin C levels with peripheral monocyte blood count (regression coefficient ± SE: 12 ± 3.38, P < 0.001) and white blood count (0.616 ± 0.278, P= 0.027) was evident. In this multiple linear regression analysis, other inflammatory markers (i.e. hs-CRP, haptoglobin, ferritin, albumin) did not seem to affect cystatin C blood levels. CONCLUSION The results of this study demonstrated that monocytes, which play an important role in chronic inflammation and atherosclerosis, were independently related with cystatin C concentrations. This finding may provide a plausible link for the usefulness of cystatin C in predicting increased cardiovascular risk.

Abstract
BACKGROUND There is epidemiological evidence that Mediterranean diet exposure is associated with lower asthma prevalence in children. We aimed to summarize the available data and to know whether the Mediterranean setting modifies this association. METHODS The literature search, up to May 2012, was on epidemiological studies in the general population of children assessing whether adherence to Mediterranean diet (measured as a score) was associated with the prevalence of 'current wheeze'; 'current severe wheeze'; or 'asthma ever'. Odds ratios (OR) of the eight included studies compared the highest tertile of the score with the lowest. Random-effects meta-analyses for the whole group of studies and stratified by Mediterranean setting (centers <100 Km from the Mediterranean coast) were performed. Differences between strata were assessed using the Q test. RESULTS For 'current wheeze', there was a negative significant association with the highest tertile of Mediterranean diet score (OR 0.85, 95% CI 0.75-0.98; p = 0.02), driven by Mediterranean centers (0.79, 0.66-0.94, p = 0.009), although the difference with the non-Mediterranean centers (0.91, 0.78-1.05, p = 0.18) was not significant. The results for 'current severe wheeze' were as follows: 0.82, 0.55-1.22, p = 0.330 (all); 0.66, 0.48-0.90, p = 0.008 (Mediterranean); and 0.99, 0.79-1.25, p = 0.95 (non-Mediterranean); with the difference between regions being significant. For 'asthma ever', the associations were as follows: 0.86, 0.78-0.95, p = 0.004 (all); 0.86, 0.74-1.01, p = 0.06 (Mediterranean); 0.86, 0.75-0.98; p = 0.027 (non-Mediterranean); with the difference between regions being negligible. CONCLUSIONS Adherence to the Mediterranean diet tended to be associated with lower occurrence of the three respiratory outcomes. For current and current severe wheeze, the association was mainly driven by the results in Mediterranean populations.

Abstract
BACKGROUND AND AIMS Although significant evidence exists regarding the role of specific foods and dietary patterns on the development of cardiovascular disease, the influence of eating practices has not been thoroughly examined and understood. The aim of the present work was to evaluate the independent role of eating practices on the likelihood of developing an acute coronary syndrome (ACS) or ischemic stroke. METHODS AND RESULTS During 2009-2010, 1000 participants were enrolled; 250 were consecutive patients with a first ACS, 250 were consecutive patients with a first ischemic stroke and 500 were population-based control subjects (250 age-sex matched one-for-one with ACS patients, and 250 age-sex matched one-for-one with stroke patients). Eating practices were evaluated using a special questionnaire. Socio-demographic, clinical, psychological, dietary and other lifestyle characteristics were also measured. After controlling for potential confounding factors, each 20 min prolongation of dinner-to-sleep time was associated with 10% lower likelihood of ischemic stroke (95%CI: 0.83-0.98). Furthermore, eating practices related to stress (i.e., eating while being stressed, eating while working at the same time, skipping a meal due to work obligations) were associated with higher likelihood of having an ACS. Finally, eating while watching television was associated with lower likelihood of having an ACS (OR: 0.46, 95%CI: 0.27-0.78) or stroke event (OR: 0.42, 95%CI: 0.23-0.77). CONCLUSION Results of this work, present novel information, indicating the significance of eating practices, in addition to dietary patterns, regarding the development of coronary heart disease and stroke, and could be used in the primary prevention of CVD.

Abstract
BACKGROUND AND AIM The aim of this work was to evaluate the repeatability and the validity of a food frequency questionnaire (FFQ), and to discuss the methodological framework of such procedures. METHODS AND RESULTS The semi-quantitative FFQ included 69 questions regarding the frequency of consumption of all main food groups and beverages usually consumed and 7 questions regarding eating behaviors. Five hundred individuals (37 ± 15 yrs, 38% males) were recruited for the repeatability process, while another 432 (46 ± 16 yrs, 40% males) also completed 3-Day Diaries (3DD) for the validation process. The repeatability of the FFQ was adequate for all food items tested (Kendall's tau-b: 0.26-0.67, p < 0.05), energy and macronutrients intake (energy adjusted correlation coefficients ranged between 0.56-0.69, p < 0.05). Moderate validity of the FFQ was observed for "dairy products", "fruit", "alcohol" and "stimulants" (tau-b: 0.31-0.60, p < 0.05), whereas low agreement was shown for "starchy products", "legumes", "vegetables", "meat", "fish", "sweets", "eggs", "fats and oils" (tau-b < 0.30, p < 0.05). The FFQ was also valid regarding energy and macronutrients intake. Sensitivity analyses by sex and BMI category (< or ≥25 kg/m(2)) showed similar validity of the FFQ for all food groups (apart from "fats and oils" intake), as well as energy and nutrient intake. CONCLUSION The proposed FFQ has proven repeatable and relatively valid for foods' intake, and could therefore be used for nutritional assessment purposes.
