Improving Children's Lifestyle and Quality of Life through Synchronous Online Education: The Nutritional Adventures School-Based Program.

The early introduction of effective nutritional educational programs is pivotal for instilling sustainable healthy behaviors. The present work aims to present a best practice example of a nutrition and overall lifestyle school-based training program, the Nutritional Adventures ("Diatrofoperipeteies"). Conducted during 2020-2022 in Greek primary schools, this synchronous, online educational initiative included two 1-school-hour activities with a nutrition instructor. Additionally, schools were randomly assigned to supplementary "at-home" supported-by-parents or "in-class" supported-by-educators educational activities. In total, n = 12,451 students of 84 primary schools participated. Parent-completed questionnaires were selected in the recruitment and post-intervention phase (40% participation rate); overall, the working sample was n = 1487 students. In the post-intervention phase, a significant increase in Mediterranean diet adherence was observed (KIDMED score: mean increment = 0.25 units; p < 0.001), particularly fruit and vegetable consumption. Time spent on physical activity increased, while screen time decreased. Students' total quality of life significantly improved (PedsQL; mean increment = 1.35 units; p < 0.001), including on all of its subscales (physical, emotional, social, and school function). Supplementary educational activities that were supported by educators rather than parents yielded a more favorable impact on students' lifestyle and quality of life. The Nutritional Adventures program can be regarded as a successful initiative in primary schools, yielding immediate advantages that extend beyond promoting healthy dietary habits.

Older People in Emergencies; Addressing Food Insecurity, Health Status and Quality of Life: Evaluating the "365+ Days of Care" Program.

During emergencies, older adults stand among the most vulnerable, facing long-lasting food insecurity and overall health issues. The "365+ Days of Care" food aid program addressed food insecurity and poor quality of life among vulnerable older adults following a devastating wildfire in Greece. Our aim was to evaluate the program's efficiency, using a process evaluation framework and a partial cost-utility analysis. In total, n = 133 wildfire-hit residents (≥65 years) received daily tailored, pre-cooked meals and/or weekly food packages. The study outcomes were assessed from baseline to 12 months later. Focus groups and interviews (n = 30), researcher observations, and questionnaires were used to assess the beneficiaries' perception of the initiative. Within the 12-month follow-up period, food insecurity and malnutrition risk decreased, whereas Mediterranean diet adherence; quality of life; and physical, social, and mental health were improved (p < 0.05). A one-point increase in food insecurity was positively associated with improved quality of life, general health, limitation in activities, body pain, vitality, and pain/discomfort (p's < 0.05), and it was marginally associated with mobility, anxiety/depression, and self-evaluated health status (p's < 0.1). Quantitative and qualitative data characterized it as successful, acceptable, beneficial, and of high quality. The partial cost-utility ratio was one QALY gained per EUR 22.608. The utilization of well-designed food aid programs during emergencies can alleviate food insecurity and improve quality of life in older adults.

Dietary patterns and food insecurity of students participating in a food aid programme: the Mediterranean perspective.

BACKGROUND: To explore the effect of household food insecurity on dietary patterns of children and adolescents participating in a school food-aid programme in regions of Greece with low socioeconomic status. METHODS: A cross-sectional study was conducted during the school year 2013-14, among 406 schools in low socioeconomic status regions of Greece. Dietary habits and sociodemographic characteristics of students and their families were recorded. Factor analysis was used in order to derive children's and adolescents' dietary patterns and analysis of covariance was performed to examine the effect of households' food insecurity level on those patterns. A total of 31 399 students participated in the study; 16 652 children (5-11 years) and 14 747 adolescents (12-18 years). RESULTS: Factor analysis identified five dietary patterns in both age groups, explaining the 49.1% (children) and 53.0% (adolescents) of the total variation in intake. After adjusting for various factors, the household's food insecurity was significantly associated with the majority of the derived patterns in both age groups, with most pronounced differences being observed for the consumption of red meat, poultry and fish, fruits, as well as red processed meat, cereals and dairy products, which was lower among children and adolescents with food insecurity. Children with food insecurity consumed significantly more unhealthy food, such as chips, fast food, sugared drinks, sweets, French fries and mayonnaise sauce. CONCLUSIONS: Promotion of healthy eating to households facing food insecurity is of crucial importance, giving emphasis in the design of low cost, yet highly nutritious programmes.

Effectiveness of a school food aid programme in improving household food insecurity; a cluster randomized trial.

BACKGROUND: Aim of this cluster randomized trial was to examine the impact of a school feeding programme combining healthy meals provision and educational activities to reduce food insecurity. METHODS: Schools participating in the DIATROFI Program in Greece during the 2014-2015 school year were randomly allocated between a multicomponent intervention (MI: each student received a daily healthy meal along with educational actions; 28 schools) and an educational intervention (EI; 23 schools). A linear-mixed model was used to examine intervention effect on change from baseline in the food insecurity score, as measured via the Food Security Survey Module (FSSM). The analysis was based on 1442 pre-post intervention questionnaire pairs in the MI group and 986 in the EI group. RESULTS: The reduction in food insecurity score in the MI group was statistically significantly greater compared to the EI group, by 9.8% or -0.31 [95% confidence interval (CI) -0.61 to -0.01] FSSM units after adjusting for potential confounders. MI intervention was significantly more effective compared to EI, among students in food insecure households (mean -0.44, 95% CI -0.84 to -0.04), students in households facing hunger (mean -1.04, 95% CI -1.91 to -0.17) and overweight/obese students (mean -0.36, 95% CI -0.72 to -0.01). CONCLUSION: For interventions aiming to address childhood food insecurity, public health focus should be oriented towards school-based programmes combining food assistance with activities that promote healthy nutrition.

National Dietary Guidelines of Greece for children and adolescents: a tool for promoting healthy eating habits.

OBJECTIVE: Dietary guidelines are an essential policy tool for facilitating optimal dietary patterns and healthy eating behaviours. We report: (i) the methodological approach adopted for developing the National Dietary Guidelines of Greece (NDGGr) for Infants, Children and Adolescents; and (ii) the guidelines for children aged 1-18 years. DESIGN: An evidence-based approach was employed to develop food-based recommendations according to the methodologies of the WHO, FAO and European Food Safety Authority. Physical activity recommendations were also compiled. Food education, healthy eating tips and suggestions were also provided. SETTING: The NDGGr encompass food-based nutritional and physical activity recommendations for promoting healthy dietary patterns and eating behaviours and secondarily to serve as a helpful tool for the prevention of childhood overweight and obesity. RESULTS: The NDGGr include food-based recommendations, food education and health promotion messages regarding: (i) fruits; (ii) vegetables; (iii) milk and dairy products; (iv) cereals; (v) red and white meat; (vi) fish and seafood; (vii) eggs; (viii) legumes; (ix) added lipids, olives, and nuts; (x) added sugars and salt; (xi) water and beverages, and (xii) physical activity. A Nutrition Wheel, consisting of the ten most pivotal key messages, was developed to enhance the adoption of optimal dietary patterns and a healthy lifestyle. The NDGGr additionally provide recommendations regarding the optimal frequency and serving sizes of main meals, based on the traditional Greek diet. CONCLUSIONS: As a policy tool for promoting healthy eating, the NDGGr have been disseminated in public schools across Greece.

Daily distribution of free healthy school meals or food-voucher intervention? Perceptions and attitudes of parents and educators.

AIMS: To qualitatively evaluate the optimal intervention (food-voucher approach vs. free daily meal distribution), aimed at reducing food insecurity and promoting healthy eating among students attending public schools in socioeconomically disadvantaged areas. METHODS: We randomly assigned 34 schools to one of the two interventions: students in 17 schools received a daily lunch-box and parents in the other 17 schools received a food voucher of equal value once a month. All students were offered the opportunity to participate. We conducted 30 focus groups in all participating schools (17 in the meal distribution and 13 in the food voucher schools). Eligible participants included parents (n = 106), educators (n = 66) and school principals (n = 34). We qualitatively evaluated their perceptions and attitudes towards the program. RESULTS: Important differences were observed between the two approaches, with more favourable perceptions being reported for the meal distribution approach. More specifically, social stigmatization was minimized in the meal distribution approach, through the participation of all students, compared with the food-voucher participants who reported feelings of embarrassment and fear of stigmatization. Secondly, the meal distribution approach alleviated child food insecurity through the provision of the daily meal, while the food-voucher intervention helped manage household food insecurity, as vouchers were mainly used for purchasing food for family meals. Furthermore, the educational and experiential nature of the meal distribution approach intensified healthy eating promotion, while the food-voucher intervention was efficient mainly for conscious parents regarding healthy eating. CONCLUSIONS: The meal distribution intervention was considered more effective than the food-voucher one. Hence, for interventions aiming at tackling food insecurity of children and adolescents, public health focus could be oriented towards school-based in kind food assistance.

Promotion of healthy nutrition among students participating in a school food aid program: a randomized trial.

OBJECTIVES: To evaluate the potential benefits on students' eating habits, of incorporating healthy nutrition education as part of a school food aid program. METHODS: 146 schools participating in the DIATROFI Program in Greece during the 2013-2014 school year were randomly allocated to the environmental intervention (received a healthy daily meal) and the multicomponent intervention (MI) group (in addition to the meal, a healthy nutrition educational program was applied). The analysis, based on 3627 pre-post intervention questionnaire pairs, was stratified for children (ages 4-11 years) and adolescents (ages 12-18 years). RESULTS: Children participating in the MI group displayed 25 % higher odds of increasing the weekly consumption of milk/yoghurt and fruits, 61 % higher odds of improving BMI from overweight/obese to normal and 2.5 times higher odds of improving from underweight to normal. For adolescents in the MI group, the odds of increasing the consumption of vegetables were 40 % higher. In both intervention groups, approximately one in four overweight/obese adolescents reached normal weight. CONCLUSIONS: Educational programs on healthy nutrition might be considered worth implementing in the framework of school food aid programs.

Metabolic syndrome, adherence to the Mediterranean diet and 10-year cardiovascular disease incidence: The ATTICA study.

BACKGROUND AND AIMS: To better understand the metabolic syndrome (MS) spectrum through principal components analysis and further evaluate the role of the Mediterranean diet on MS presence. METHODS: 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. MS was defined by the National Cholesterol Education Program Adult Treatment panel III (revised NCEP ATP III) definition. Adherence to the Mediterranean diet was assessed using the MedDietScore (range 0-55). RESULTS: Five principal components were derived, explaining 73.8% of the total variation, characterized by the: a) body weight and lipid profile, b) blood pressure, c) lipid profile, d) glucose profile, e) inflammatory factors. All components were associated with higher likelihood of CVD incidence. After adjusting for various potential confounding factors, adherence to the Mediterranean dietary pattern for each 10% increase in the MedDietScore, was associated with 15% lower odds of CVD incidence (95%CI: 0.71-1.06). For the participants with low adherence to the Mediterranean diet all five components were significantly associated with increased likelihood of CVD incidence. However, for the ones following closely the Mediterranean pattern positive, yet not significant associations were observed. CONCLUSION: Results of the present work propose a wider MS definition, while highlighting the beneficial role of the Mediterranean dietary pattern.

The influence of a school-based intervention programme regarding adherence to a healthy diet in children and adolescents from disadvantaged areas in Greece: the DIATROFI study.

BACKGROUND: To evaluate the effects, via a cohort study, of a food aid and promotion of healthy nutrition programme, implemented in areas of low socioeconomic status (SES) in Greece, on students' diet quality. METHODS: From a total of 162 schools participating in the programme during the 2012-2013 school year, we collected 3941 individually linked questionnaires at baseline and at the end of the intervention, recording sociodemographic characteristics, lifestyle parameters and dietary habits of the students. For the assessment of diet quality, the KIDMED score was computed, along with food frequency consumption data regarding milk, fruits, vegetables and whole grain products. Pre-post intervention values were compared using non-parametric tests. Generalised estimating equations were used to explore the factors that influence changes in dietary habits. RESULTS: By the end of the intervention, favourable changes were observed regarding healthy eating; KIDMED increased statistically significantly in adolescent girls (p=0.042), while the consumption frequency of all foods promoted by the intervention, namely, milk, fruits, vegetables and whole grain products, increased for children and adolescents, boys and girls (p≤0.002). Factors indicating lower SES, such as foreign country of birth, lower education level, no income source and high levels of food insecurity, were associated with lower diet quality. CONCLUSIONS: As low SES groups tend to adopt unhealthier dietary choices, it is of the outmost importance to take action for the promotion of healthy eating, directed especially to these at risk populations. School-based nutritional programmes can be considered as an effective policy measure towards this direction.

Socio-economic and lifestyle parameters associated with diet quality of children and adolescents using classification and regression tree analysis: the DIATROFI study.

OBJECTIVE: To explore factors affecting children's and adolescents' diet quality, in the framework of a food aid and promotion of healthy nutrition programme implemented in areas of low socio-economic status of Greece, during the current financial crisis. DESIGN: From a total of 162 schools participating in the programme during 2012-2013, we gathered 15 897 questionnaires recording sociodemographic characteristics, lifestyle parameters and dietary habits of children and their families. As a measure of socio-economic status, the Family Affluence Scale (FAS) was used; whereas for the assessment of diet quality, the KIDMED score was computed. Associations between KIDMED and FAS, physical activity and socio-economic parameters were examined using regression and classification-regression tree analysis (CART). RESULTS: The higher the FAS score, the greater the percentage of children and adolescents who reported to consume, on a daily basis, fruits and vegetables, dairy products and breakfast (P<0·001). Results from CART showed that children and adolescents in the medium or high FAS groups had higher KIDMED score, compared with those in the low FAS group. For those in the low FAS group, KIDMED score is expected to increase by 12·4 % when they spend more than 0·25 h/week in sports activities. The respective threshold for the medium and high FAS groups is 1·75 h/week, while education of the mother and father affected KIDMED score significantly as well. CONCLUSIONS: Diet quality is strongly influenced by socio-economic parameters in children and adolescents living in economically disadvantaged areas of Greece, so that lower family affluence is associated with worse diet quality.

Defining the Path Between Social and Economic Factors, Clinical and Lifestyle Determinants, and Cardiovascular Disease.

BACKGROUND: Low socioeconomic status is associated with poorer cardiovascular health. OBJECTIVES: The aim of the present work was to evaluate how social and economic factors influence modifiable cardiovascular disease risk factors and thus, acute coronary syndrome or ischemic stroke presence. METHODS: One thousand participants were enrolled; 250 consecutive patients with a first acute coronary syndrome (83% were male, 60 ± 12 years old) and 250 control subjects, as well as 250 consecutive patients with a first ischemic stroke (56% were male, 77 ± 9 years old) and 250 control subjects. The control subjects were population-based and age-sex matched with the patients. Detailed information regarding their medical records, lifestyle characteristics, education level, financial status satisfaction, and type of occupation were recorded. RESULTS: After controlling for potential confounding factors, significant inverse associations were observed regarding financial status satisfaction and sedentary/mental type occupation with acute coronary syndrome or stroke presence, but not with the educational level. Nevertheless, further evaluation using path analysis, revealed quite different results, indicating that the education level influenced the type of occupation and financial satisfaction, hence affecting indirectly the likelihood of developing a cardiovascular disease event. CONCLUSIONS: Social and economic parameters interact with modifiable cardiovascular disease risk factors through multiple pathways.

Eating behaviors and their relationship with cardiovascular disease. A case/case-control study.

The aim of the present work was to evaluate the combined role of eating behaviors and to investigate their effect on the likelihood of developing an acute coronary syndrome (ACS) or an ischemic stroke. During 2009-2010, 1000 participants were enrolled; 250 consecutive patients with a first ACS (83% males, 60 ± 12 years) and 250 control subjects, as well as 250 consecutive patients with a first ischemic stroke (56% males, 77 ± 9 years) and 250 controls. The controls were population-based and age-sex matched with the patients. Detailed information regarding their anthropometric data, medical records and lifestyle characteristics (dietary and smoking habits, physical activity, psychological state and eating practices -using a special questionnaire-) were recorded. Five eating behaviors were selected to compose an eating behavior score for the purposes of this work: adherence to the Mediterranean diet (using the MedDietScore), frequency of breakfast consumption, eating while being stressed, eating while working and skipping meals. Eating behaviors with beneficial health effects were scored with 0, while those with negative effects were assigned score 1. The total range of the score was between 0 and 5. Higher scores reveal "unhealthier" eating practices. After controlling for potential confounding factors, each unit increase of the eating behavior score was associated with 70% (95% CI: 1.29-2.22) higher likelihood of developing an ACS. Insignificant associations were observed regarding ischemic stroke. The overall adoption of specific "unhealthy" eating practices seems to have a detrimental effect on cardiovascular health, and especially coronary heart disease.

Association between mediterranean diet and non-fatal cardiovascular events, in the context of anxiety and depression disorders: a case/case-control study.

INTRODUCTION: The aim of this study was to investigate the effect of the Mediterranean diet on the likelihood of having a non-fatal cardiovascular outcome, taking into account anxiety and depression status. METHODS: This was a case-control study with individual matching by age and sex. During 2009-2010, 1000 participants were enrolled; 250 were consecutive patients with a first acute coronary syndrome (ACS), 250 were consecutive patients with a first ischemic stroke, and 500 were population-based control subjects, one-for-one matched to the patients by age and sex. Among other characteristics, adherence to the Mediterranean diet was assessed by the MedDietScore, anxiety was assessed with the Spielberger State-Trait Anxiety Inventory form Y-2, while depressive symptomatology was evaluated by the Zung Depression Rating Scale. RESULTS: Higher adherence to the Mediterranean diet was associated with a lower likelihood of ACS and ischemic stroke, even after adjusting for anxiety or depression (ACS: OR=0.92, 95%CI 0.87-0.98 and 0.93, 0.88-0.98, respectively; ischemic stroke: 0.91, 0.84-0.98 and 0.90, 0.83-0.97, respectively). For both ACS and stroke patients, anxiety and depression were associated with a higher likelihood of ACS and stroke. When stratifying for depression or anxiety status, the Mediterranean diet remained a significantly protective factor only for people with low levels of depression and anxiety for ACS, and only for people with low levels of anxiety, as far as stroke was concerned. CONCLUSION: Anxiety and depression seem to play a mediating role in the protective relationship between adherence to the Mediterranean diet and the likelihood of developing cardiovascular events.

Comparative analysis of a-priori and a-posteriori dietary patterns using state-of-the-art classification algorithms: a case/case-control study.

OBJECTIVE: To compare the accuracy of a-priori and a-posteriori dietary patterns in the prediction of acute coronary syndrome (ACS) and ischemic stroke. This is actually the first study to employ state-of-the-art classification methods for this purpose. METHODS AND MATERIALS: During 2009-2010, 1000 participants were enrolled; 250 consecutive patients with a first ACS and 250 controls (60±12 years, 83% males), as well as 250 consecutive patients with a first stroke and 250 controls (75±9 years, 56% males). The controls were population-based and age-sex matched to the patients. The a-priori dietary patterns were derived from the validated MedDietScore, whereas the a-posteriori ones were extracted from principal components analysis. Both approaches were modeled using six classification algorithms: multiple logistic regression (MLR), naïve Bayes, decision trees, repeated incremental pruning to produce error reduction (RIPPER), artificial neural networks and support vector machines. The classification accuracy of the resulting models was evaluated using the C-statistic. RESULTS: For the ACS prediction, the C-statistic varied from 0.587 (RIPPER) to 0.807 (MLR) for the a-priori analysis, while for the a-posteriori one, it fluctuated between 0.583 (RIPPER) and 0.827 (MLR). For the stroke prediction, the C-statistic varied from 0.637 (RIPPER) to 0.767 (MLR) for the a-priori analysis, and from 0.617 (decision tree) to 0.780 (MLR) for the a-posteriori. CONCLUSION: Both dietary pattern approaches achieved equivalent classification accuracy over most classification algorithms. The choice, therefore, depends on the application at hand.

Mediterranean diet and metabolic syndrome: an updated systematic review.

The metabolic syndrome is a health condition characterized by abdominal obesity, dyslipidemia, elevated blood pressure and impaired glucose tolerance, with increasing prevalence. Adherence to the Mediterranean diet seems to exert beneficial effects regarding the metabolic syndrome prevalence and progression. Thus, we performed an updated systematic review of studies which have evaluated the effect of the Mediterranean dietary pattern on the metabolic syndrome. This was a systematic review of epidemiological observational studies and clinical trials. English language publications in the databases PubMed, Embase, Scopus, until May 31, 2013, were included in this review. New evidence from prospective cohort studies, cross-sectional studies and clinical trials supports the beneficial role of adherence to the Mediterranean dietary pattern regarding metabolic syndrome presence and progression. Considering the magnitude of metabolic syndrome, efforts should be made to encourage adoption of this pattern in Mediterranean countries and similar dietary pattern in countries where metabolic syndrome is prevalent.

Comparative analysis of cardiovascular disease risk factors influencing nonfatal acute coronary syndrome and ischemic stroke.

The aim of the present work was to compare the influence of classic cardiovascular disease (CVD) risk factors on the development of acute coronary syndrome (ACS) and ischemic stroke. During 2009-2010, 1,000 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, 1-for-1 matched to the patients by age and gender. The following CVD risk factors were evaluated: smoking/passive smoking, family history of CVD, physical inactivity, hypertension, hypercholesterolemia, diabetes mellitus, presence of overweight and obesity, trait anxiety (assessed with the Spielberger State-Trait Anxiety Inventory form Y-2), and adherence to the Mediterranean diet (assessed by the MedDietScore). Furthermore, participants graded the perceived significance of the aforementioned factors, using a scale from 1 (not important) to 9 (very important). The risk factors with the highest effect size for ACS, as determined by the Wald criterion, were smoking and hypercholesterolemia; regarding stroke, they were anxiety and family history of CVD (all p <0.01). When the odds ratios of each factor for ACS and stroke were compared, insignificant differences were observed, except for smoking. On the basis of the participants' health beliefs, smoking and stress emerged as the most important risk factors, whereas all subjects graded passive smoking as a least important factor. In conclusion, similarities of the risk factors regarding ACS and ischemic stroke facilitate simultaneous primary prevention measures.

The mediating effect of the Mediterranean diet on the role of discretionary and hidden salt intake regarding non-fatal acute coronary syndrome or stroke events: case/case-control study.

OBJECTIVES: The aim of the present work was to evaluate the association between salt and salty food consumption on the development of an acute coronary syndrome (ACS) or ischemic stroke, under the context of adherence to the Mediterranean diet. METHODS: 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 population-based, control subjects, one-for-one matched to the patients by age and sex. Socio-demographic, clinical, psychological, dietary and other lifestyle characteristics were measured. Consumption of foods with high salt concentration was evaluated with a special score (range 0-10). Adherence to the Mediterranean diet was assessed by the validated MedDietScore (theoretical range: 0-55). RESULTS: After adjustment for potential confounding factors, use of salt added in table was associated with 81% higher likelihood of stroke (95% Confidence Interval: 1.03-3.20), whereas no association was observed regarding the development of ACS. Salt use during cooking was not associated with the development of ACS or stroke. Each unit increase of the score evaluating total salty food consumption was associated with 33% higher likelihood of stroke development (95% Confidence Interval: 1.08-1.64), but not with ACS. The effect of salt and salty food consumption regarding stroke presence was more evident for participants with lower adherence to the Mediterranean diet. CONCLUSION: Simple dietary changes, with emphasis on reducing salt and salty food consumption, along with better adherence to the Mediterranean diet, should be incorporated in public health strategies for the primary prevention of stroke.

The obesity paradox: methodological considerations based on epidemiological and clinical evidence--new insights.

Despite the well-known association of obesity with increased mortality and the development of chronic diseases, an "obesity paradox" has been reported in several patient categories; i.e., overweight and obese patients have a better prognosis than normal or low-weight individuals. The present review aims to identify potential factors lying beneath the beneficial effect of overweight and obesity. In particular, the role of nutritional status, malnutrition and catabolic state, as well as intentional vs. unintentional weight loss and the possibility of a U-shape relationship between body mass index and survival will be examined. Furthermore, methodological considerations framing the obesity paradox will be presented and discussed.

Adherence to the mediterranean diet in relation to ischemic stroke nonfatal events in nonhypercholesterolemic and hypercholesterolemic participants: results of a case/case-control study.

The aim of the present work was to evaluate the association between adherence to the Mediterranean diet and the development of ischemic stroke according to cholesterol levels. During 2009-2010, 500 participants were enrolled; 250 were consecutive patients (77 ± 9 years, 55.6% men) with a first ischemic stroke and 250 population-based, control participants, matched to the patients by age and sex. Sociodemographic, clinical, dietary, and other lifestyle characteristics were measured. Adherence to the Mediterranean diet was assessed by the validated MedDietScore (theoretical range: 0-55). After various adjustments, each 1/55 unit increase in the MedDietScore was associated with 17% lower likelihood of having an ischemic stroke in nonhypercholesterolemic participants (95%CI: 0.72-0.96) and 10% lower likelihood in participants with hypercholesterolemia (95%CI: 0.81-0.99). The present work highlights the cardioprotective benefits from the adoption of the Mediterranean diet, by showing its beneficial effect regarding ischemic stroke development, regardless of the presence of hypercholesterolemia.

Adherence to the Mediterranean diet in relation to acute coronary syndrome or stroke nonfatal events: a comparative analysis of a case/case-control study.

BACKGROUND: Although the role of Mediterranean diet on cardiovascular disease prevention has long been evaluated and understood, its association with the development of stroke has been rarely examined. The aim of the present work was to comparatively evaluate the association between adherence to the Mediterranean diet and the development of an acute coronary syndrome (ACS) or ischemic stroke. METHODS: During the period from 2009 to 2010, 1,000 participants were enrolled; 250 were consecutive patients with a first ACS, 250 were consecutive patients with a first ischemic stroke, and 500 population-based, control subjects, 1-for-1 matched to the patients by age and sex. Sociodemographic, clinical, psychological, dietary, and other lifestyle characteristics were measured. Adherence to the Mediterranean diet was assessed by the validated MedDietScore (theoretical range 0-55). RESULTS: After various adjustments were made, it was observed that for each 1-of-55-unit increase of the MedDietScore, the corresponding odds ratio for having an ACS was 0.91 (95% CI 0.87-0.96), whereas regarding stroke, it was 0.88 (95% CI 0.82-0.94). CONCLUSIONS: The present work extended the current knowledge about the cardioprotective benefits from the adoption of the Mediterranean diet by showing an additional protective effect on ischemic stroke development.
