Adherence to the Mediterranean Diet in Saudi Arabia and Its Association with Socioeconomic Status and Depression.

Background and Objectives: Several RCTs have reported significant reductions in depression symptoms with the Mediterranean diet (MedDiet), but observational studies have reported inconsistent findings. Moreover, studies have rarely investigated the mediating role of socioeconomic status (SES), including objective material status, in adherence to the MedDiet and its impact on depressive symptoms in the same population. Therefore, this cross-sectional study investigated the relationship between adherence to the MedDiet, socioeconomic factors, and depression severity. Materials and Methods: A cross-sectional online survey was conducted between June and December 2022 across Saudia Arabia. The snowball sampling technique was used to recruit participants aged ≥18 years. Mediterranean diet adherence screener (MEDAS) and Patient Health Questionnaire-9 (PHQ-9) were used to assess adherence to the MedDiet and depression severity. An SES index, validated in the Saudi Arabian context, was used to assess SES. The data were analyzed using the Chi-square and Pearson's correlation tests. Results: Only 21% of our study population (n = 467) was MedDiet adherent. Adherence was significantly associated with education (p = 0.014) but not employment status among traditional SES indicators. Similarly, only television ownership (p = 0.009) was associated with MedDiet adherence among the 20 objective material possessions investigated. Nonetheless, the MedDiet-adherent group had a significantly lower PHQ-9 score than the non-adherent group (6.16 ± 0.68 vs. 8.35 ± 0.31, p = 0.002). A moderate but significantly negative correlation between MEDAS and PHQ-9 scores (r = -0.16, p = 0.001) was noted. Conclusions: MedDiet adherence was associated with lower depression severity scores. In addition to education and television ownership, adherence was not associated with any objective indicators of SES.

The Role of Socioeconomic Status in Adherence to the Mediterranean Diet and Body Mass Index Change: A Follow-Up Study in the General Population of Southern Croatia.

The Mediterranean diet (MD) is one of the most healthful dietary patterns, beneficial for humans and the environment. However, the MD has recently exhibited a declining trend, especially in younger and less affluent people. This study investigated the association between socioeconomic indicators and adherence to the MD in 4671 adult subjects from Dalmatia, Croatia (age range 18-98 years; 61.9% were women). Additionally, in the follow-up we examined the change in adherence to the MD and in BMI (subsample, N = 1342; 62.5% were women; mean follow-up time of 5.8 years). The adherence to the MD was based on the Mediterranean Diet Serving Score (range 0-24 points, cut-off value ≥ 14 points), with a prevalence in the overall sample of 28.5%. Higher odds of adherence to the MD were recorded in women, older subjects, and those with higher level of objective material status, while it was less likely in the period after economic crisis of 2007-2008. Additionally, we detected no change in adherence to the MD in the follow-up subsample (-8.5%, p = 0.056), but there was an increase in BMI (+6.5%, p < 0.001). We recorded an increase in adherence for nuts (+127.5%), sweets (+112.6%), red meat (+56.4%), and wine (+50.0%), unlike the reduction in adherence for vegetables (-35.1%), fish (-23.4%), white meat (-11.6%), cereals (-10.9%), and dairy products (-9.6%). Similar results were obtained across all quartiles of objective material status. Over time, the absolute change in the MD score was positively associated with female gender, age, higher education, and moderate physical activity, but it was negatively associated with adherence to the MD at baseline. BMI change was positively associated with female gender, and negatively with initial BMI, initial adherence to the MD, and MD change. Our findings point towards a less than ideal adherence to the MD in the general population of southern Croatia, and identify important characteristics associated with adherence change over time, informing necessary interventions aimed at increasing MD uptake.

Adherence to the Mediterranean Diet in Association with Self-Perception of Diet Sustainability, Anthropometric and Sociodemographic Factors: A Cross-Sectional Study in Italian Adults.

The adoption of sustainable dietary models, such as the Mediterranean Diet (MD), can be a valuable strategy to preserve ecosystems and human health. This study aims to investigate in an Italian adult representative sample the adherence to the MD and to what extent it is associated with the self-perceived adoption of a sustainable diet, the consideration of the MD as a sustainable dietary model, and anthropometric and sociodemographic factors. By applying an online survey (n = 838, 18-65 years, 52% female), an intermediate level of MD adherence (median: 4.0, IR: 3.0-4.0) in a 0-9 range was observed. Only 50% of the total sample confirmed the MD as a sustainable dietary model, and 84% declared no or low perception of adopting a sustainable diet. Being female, having a higher income and education level, considering the MD as a sustainable dietary model, as well as the perception of having a sustainable diet were the most relevant factors influencing the probability of having a high score (≥6) of adherence to the MD. This study suggests a gradual shift away from the MD in Italy and supports the need to address efforts for developing intervention strategies tailored to adults for improving diet quality. Furthermore, a public campaign should stress the link between a diet and its environmental impact to foster nutritionally adequate and eco-friendly dietary behaviors.

Assessment of dietary habits and the adequacy of dietary intake of patients with cirrhosis-the KIRRHOS study.

BACKGROUND & AIMS: Undernutrition is widely prevalent in patients with cirrhosis and affects prognosis. Given the lack of data regarding the dietary intake (DI) and habits of patients with cirrhosis, the aim of the present study was to evaluate them by assessing diet's adequacy compared to the new guidelines, and the association of DI with nutritional status indicators. METHODS: One hundred and eighty-seven patients (57.8% male, 59.9 ± 10.9 years old, 44.9% decompensated ones) with cirrhosis of various etiologies were enrolled. The patients' DI was assessed using three 24 h recalls, which were analyzed regarding macronutrients' intake, food groups consumption, adherence to the Mediterranean diet and meal patterns. The Goldberg cut-off limits for the ratio of energy intake to resting energy expenditure were used to evaluate dietary underreporting and patients were accordingly classified as low or adequate energy reporters (LERs and AERs). RESULTS: Among the AERs (n = 91, 48.7%) only 29.7% and 31.9% met current recommendations regarding energy and protein intake, accordingly. Patients reported low intake of several healthy food groups and low adherence to the Mediterranean diet. They reported a median of 4.3 eating episodes per day and they frequently omitted late evening snack. Nevertheless, no statistically significant associations were found between parameters of DI and annual and two-year survival. CONCLUSIONS: Low energy reporting was very frequent in this sample of patients with liver cirrhosis. Diet quality was rather poor, whereas energy and protein intakes were lower than those recommended.

[Assessment of adherence to the Mediterranean diet in university Health Sciences students and its relationship with level of physical activity]. / Valoración de la adherencia a la dieta mediterránea en estudiantes universitarios de Ciencias de la Salud y su relación con el nivel de actividad física.

INTRODUCTION: Objective: to assess the degree of adherence to the Mediterranean diet and the practice of physical activity in university Health Sciences students in Castile-La Mancha. Methods: this was a cross-sectional, observational study by means of a dietary and physical activity survey. The sample consisted of 575 university students (77.7 % women). An initial data collection survey was developed using the Google Forms platform (https://www.google.com/forms/about/). Adherence to the Mediterranean diet was assessed with the Mediterranean Diet Adherence Screener (MEDAS) questionnaire and the modified Prevention with Mediterranean Diet (PREDIMED) questionnaire. The Rapid Assessment of Physical Activity Scale (RAPA) questionnaire was used to measure physical activity. Results: we found a 58.3 % adherence to Mediterranean diet among Health Sciences students, with 38.6 % of average adherence, and 5.0 % of poor adherence, with a low consumption of fruits with no gender differences, and a high consumption of red or processed meat and butter or cream with significant differences between women and men. There is also a high consumption of carbonated beverages (more frequent in women). Likewise, a high percentage of students (22.5 %) do practically no physical activity. As for physical exercise, it is always higher in men, with significant differences (p > 0.05). Conclusion: this study suggests that the sample of university Health Sciences students in Castile-La Mancha shows an acceptable adherence to the Mediterranean diet and insufficient levels of physical activity.

INTRODUCCIÓN: Objetivo: valorar el grado de adherencia a la dieta mediterránea y la práctica de actividad física en estudiantes universitarios de Ciencias de la Salud de Castilla-La Mancha. Método: estudio observacional transversal mediante encuesta alimentaria y de actividad física. La muestra contó con 575 estudiantes universitarios (77,7 % de mujeres). Se desarrolló una encuesta de recogida de datos inicial mediante la plataforma Google Forms (https://www.google.com/forms/about/). La adherencia a la dieta mediterránea se valoró con el cuestionario Mediterranean Diet Adherence Screener (MEDAS) y el cuestionario PREvención con DIeta MEDiterránea (PREDIMED), modificado. Para medir la actividad física se utilizó el cuestionario Rapid Assessment of Physical Activity Scale (RAPA), que valora la actividad física desempeñada. Resultados: se encontró en los estudiantes de Ciencias de la Salud una adherencia a la dieta mediterránea del 58,3 %, siendo la adherencia media del 38,6 % y la mala adherencia del 5,0 %, observándose un bajo consumo de frutas sin diferencias de sexo, un alto consumo de carne roja o procesada y de mantequillas o natas, con diferencias significativas entre mujeres y hombres. También hay un consumo alto de bebidas carbonatadas (más frecuente en mujeres). Asimismo, un porcentaje alto de estudiantes (22,5 % del total) no hace prácticamente ninguna actividad física. En cuanto al ejercicio físico, siempre es mayor entre los hombres, con diferencias significativas (p > 0,05). Conclusión: este estudio sugiere que la muestra de estudiantes universitarios de Ciencias de la Salud de Castilla-La Mancha presenta una aceptable adherencia a la dieta mediterránea y unos niveles de actividad física insuficientes.

Unhealthy Diet Pattern Mediates the Disproportionate Prevalence of Obesity among Adults with Socio-Economic Disadvantage: An Australian Representative Cross-Sectional Study.

The role of unhealthy dietary pattern in the association between socio-economic factors and obesity is unclear. The aim was to examine the association between socio-economic disadvantage and obesity and to assess mediation effect of unhealthy dietary pattern defined using the Mediterranean diet criteria. The data source was the Australian National Nutrition and Physical Activity Survey. The study sample included 7744 participants aged 18 years and over, 28% of whom had obesity. We used the Australian Socio-Economic Indexes for Areas (SEIFA) classification system for categorizing socio-economic disadvantage; calculated the Mediterranean Diet Score (MDS) using standard criteria; and used measured body mass index to define obesity. We conducted a mediation analysis using log-binomial models to generate the prevalence ratio for obesity and the proportion mediated by the MDS. The most disadvantaged group was associated with higher level of obesity after controlling for covariates (1.40, 95% CI 1.25, 1.56) compared to the least disadvantaged group, and in a dose-response way for each decreasing SEIFA quintile. The relationship between socio-economic disadvantage and obesity was mediated by the MDS (4.0%, 95% CI 1.9, 8.0). Public health interventions should promote healthy dietary patterns, such as the Mediterranean diet, to reduce obesity, especially in communities with high socio-economic disadvantage.

Mediterranean diet assessment challenges: Validation of the Croatian Version of the 14-item Mediterranean Diet Serving Score (MDSS) Questionnaire.

Mediterranean diet (MD) is among the most commonly investigated diets and recognized as one of the healthiest dietary patterns. Due to its complexity, geographical and cultural variations, it also represents a challenge for quantification. The aim of this cross-sectional study was to assess reliability and validity of the Croatian version of the 14-item Mediterranean Diet Serving Score (MDSS), using the Mediterranean Diet Adherence Screener (MEDAS) as the referent test. We included the exploratory sample of 360 medical students, and a confirmatory sample of 299 health studies students from the University of Split, Croatia. Test-retest reliability and validity of the MDSS were tested using intra-class correlation coefficients (ICC), while Cohen's kappa statistic was used to test correct classification of subjects into MD adherent/non-adherent category. A very good reliability was shown for the overall MDSS score (ICC = 0.881 [95% CI 0.843-0.909]), and a moderate reliability for the binary adherence (κ = 0.584). Concurrent validity of the MDSS was also better when expressed as a total score (ICC = 0.544 [0.439-0.629]) as opposed to the adherence (κ = 0.223), with similar result in the confirmatory sample (ICC = 0.510 [0.384-0.610]; κ = 0.216). Disappointingly, only 13.6% of medical students were adherent to the MD according to MDSS, and 19.7% according to the MEDAS questionnaire. Nevertheless, MDSS score was positively correlated with age (ρ = 0.179: P = 0.003), self-assessed health perception (ρ = 0.123; P = 0.047), and mental well-being (ρ = 0.139: P = 0.022). MDSS questionnaire is a short, reliable and reasonably valid instrument, and thus useful for assessing the MD adherence, with better results when used as a numeric score, even in the population with low MD adherence.

Mediterranean Diet, Screen-Time-Based Sedentary Behavior and Their Interaction Effect on Adiposity in European Adolescents: The HELENA Study.

Childhood obesity is a worldwide epidemic. Mediterranean diet (MD) is inversely associated with childhood obesity, but the interaction with other environmental factors, such screen time, might influence the health benefits of a high MD adherence in adolescents. The aim of the present study was to assess whether an association between MD and screen time exists in European adolescents. Moreover, we also explored whether sedentary time has a modulatory effect on the association between MD and adiposity. Adherence to the MD (24 h recalls), screen time (questionnaire), pubertal development, body mass index (BMI), fat mass index (FMI) and waist circumference (WC) were evaluated in 2053 adolescents (54.7% females), aged 12.5-17.5 years. In females, MD adherence was associated with lower BMI and FMI only when they were exposed to less than 338 min/day of screen time (81.8% of females); MD adherence was also associated with lower WC only when females were exposed to less than 143 min/day of screen time (31.5% of females). No significant MD-screen time interaction was observed in males. In conclusion, screen-time-based sedentary behaviours had a modulatory effect in the association between MD adherence and adiposity in European female adolescents.

Adherence to the Mediterranean diet according to occupation-based social classifications and gender.

BACKGROUND: The link between the dietary pattern known as the Mediterranean diet (MedDiet) and lower morbidity/mortality is well known, and its efficacy in the primary prevention of cardiovascular diseases has been proven in recent years. However, adherence to the MedDiet seems to be related to socioeconomic status. The objective was to analyze whether their adherence to the MedDiet differs from the rest of the working population. Material and methods: A transversal study was carried out on adherence to the MedDiet. One thousand six hundred nine workers were studied, of whom 626 belonged to the group of workers at risk of social exclusion. Results: It was found that 43.9% of the permanent staff had a high adherence, compared to the figure of 20.9% for the population at risk of exclusion (p < .01). No differences were evident between men and women in the same category of workers (41.7% vs. 47.9% in permanent staff and 22.5% vs. 40.5% in workers at risk of social exclusion). The lowest adherence to the MedDiet (11.4%) was found in the group of young women at risk of social exclusion. Their consumption of healthy foods was significantly lower than the group of older women, while their consumption of less healthy foods (cakes/pastries, butter and fizzy drinks) was higher. Conclusions: It is difficult to draw conclusions about whether it is the most expensive foods contained in the MedDiet which cause this difference in adherence, since, there is also a higher expenditure on non-essential products such as cakes/pastries, fizzy drinks and tobacco. Key messagesPeople at risk of social exclusion and specially the younger women have a lower adherence to the Mediterranean diet than other occupational social classes.The higher consumption of butter, fizzy drinks and cakes/pastries is the dietary habit which most affects adherence to the Mediterranean diet in the group of people at risk of exclusion.It is not possible to ensure that the higher cost of any foods included in the Mediterranean diet, such as fish and fruit, is the main cause of this difference in adherence.

Updating the Mediterranean Diet Pyramid towards Sustainability: Focus on Environmental Concerns.

BACKGROUND: Nowadays the food production, supply and consumption chain represent a major cause of ecological pressure on the natural environment, and diet links worldwide human health with environmental sustainability. Food policy, dietary guidelines and food security strategies need to evolve from the limited historical approach, mainly focused on nutrients and health, to a new one considering the environmental, socio-economic and cultural impact-and thus the sustainability-of diets. OBJECTIVE: To present an updated version of the Mediterranean Diet Pyramid (MDP) to reflect multiple environmental concerns. METHODS: We performed a revision and restructuring of the MDP to incorporate more recent findings on the sustainability and environmental impact of the Mediterranean Diet pattern, as well as its associations with nutrition and health. For each level of the MDP we provided a third dimension featuring the corresponding environmental aspects related to it. CONCLUSIONS: The new environmental dimension of the MDP enhances food intake recommendations addressing both health and environmental issues. Compared to the previous 2011 version, it emphasizes more strongly a lower consumption of red meat and bovine dairy products, and a higher consumption of legumes and locally grown eco-friendly plant foods as much as possible.

Diet quality and nutrient density in subjects with metabolic syndrome: Influence of socioeconomic status and lifestyle factors. A cross-sectional assessment in the PREDIMED-Plus study.

BACKGROUND: Socioeconomic disparities and lifestyle factors are likely to determine the overall quality of the diet. In addition, overeating is compatible with inadequate micronutrient intake and it can lead to adverse health outcomes. OBJECTIVE: To assess adequacy of dietary nutrient intake and to investigate the influence of socioeconomic and lifestyle factors on nutrient density in a large primary cardiovascular prevention trial conducted in healthy participants with metabolic syndrome (MetS) to assess the cardiovascular effects of an energy-restricted Mediterranean diet (PREDIMED-Plus). METHODS: Baseline cross-sectional analysis of the PREDIMED-Plus trial with 6646 Spanish participants (aged 55-75 years in men and 60-75 years in women) with overweight/obesity and MetS. Energy and nutrient intake (for 10 nutrients) were calculated using a validated 143-item Food Frequency Questionnaire (FFQ) and nutrient density was estimated dividing the absolute nutrient intake by total energy intake. The prevalence of inadequate intake was estimated according to dietary reference intakes. Multivariable linear regression models were fitted to examine associations between socioeconomic status or lifestyle factors and nutrient density. RESULTS: A considerable proportion of the screened participants showed a deficient intake of vitamins A, D, E, B9, calcium, magnesium and dietary fibre. Inadequate intake of four or more of the ten nutrients considered was present in 17% of participants. A higher nutrient density was directly and significantly associated with female sex, higher educational level and a better adherence to the Mediterranean diet. Lifestyle factors such as non-smoking and avoidance of sedentary lifestyles were also independently associated with better nutrient density. CONCLUSIONS: Patients with MetS, despite being overweight, exhibited suboptimal nutrient intake, especially among men. Low nutrient density diet can be largely explained by differences in socioeconomic and lifestyle factors. These results highlight the importance of focussing on nutritional education in vulnerable populations, taking into account nutrient requirements.

Efectos de un programa alternativo de promoción de la alimentación saludable en comedor escolar / Effects of an alternative program to promote healthy eating in school canteen

Resumen El objetivo del estudio fue determinar los efectos sobre los hábitos alimentarios de escolares en una intervención educativa alternativa al modelo convencional de promoción de alimentación a un centro con comedor y proyecto de huerto ecológico. Estudio observacional descriptivo de corte transversal y comparativo de 111 niños y niñas entre 9 y 12 años, en el periodo 2013-15. Se comparó un colegio con intervención alternativa con otro que únicamente incluía contenidos propios del currículo de Educación Infantil y Primaria, mediante evaluación de adherencia a la dieta mediterránea del alumnado con cuestionario validado Kidmed. El centro de intervención presentó mayor adherencia a la dieta mediterránea que el centro control. En el centro de intervención el porcentaje de alumnado con dieta óptima (64,52%) fue mayor que los que necesitaban mejorar su dieta (33,87%), mientras que en el centro fue inferior (42,86% y 51,02% respectivamente). Los escolares del centro de intervención presentaron mayor porcentaje de respuestas afirmativas en ítems Kidmed. El programa de promoción de alimentación saludable alternativo del centro de intervención podría ser efectivo para la adquisición de una dieta de mayor adherencia a la dieta mediterránea.

Abstract The objective of this study was to determine the effects on school feeding habits in an educational intervention alternative to the conventional model of feeding promotion to a center with school canteens and ecological garden project. Cross-sectional and comparative descriptive observational study of 111 boys and girls between 9 and 12 years old, in the 2013-15 period. A school with alternative intervention was compared with another one that only included contents of the Infant and Primary Education curriculum, by means of evaluation of adherence to the mediterranean diet of the students with a validated Kidmed questionnaire. The intervention center presented greater adherence to the mediterranean diet than the control center. In the intervention center, the percentage of students with optimal diet (64.52%) was higher than those who needed to improve their diet (33.87%), contrary to what occurs in control center (42.86% and 51.02% respectively). The students of the intervention center presented a higher percentage of affirmative answers in Kidmed test. The program of promotion of healthy alternative food of the intervention center could be effective for the acquisition of a diet of greater adherence to the mediterranean diet.

Dissimilar Impact of a Mediterranean Diet and Physical Activity on Anthropometric Indices: A Cross-Sectional Study from the ILERVAS Project.

There is a close relationship between lifestyle behaviors and excess adiposity. Although body mass index (BMI) is the most used approach to estimate excess weight, other anthropometric indices have been developed to measure total body and abdominal adiposity. However, little is known about the impact of physical activity and adherence to a Mediterranean diet on these indices. Here we report the results of a cross-sectional study with 6672 middle-aged subjects with low to moderate cardiovascular risk from the Ilerda Vascular (ILERVAS) project. The participants' adherence to physical activity (International Physical Activity Questionnaire short form) and MedDiet (Mediterranean Diet Adherence Screener) was evaluated. Measures of total adiposity (BMI, Clínica Universidad de Navarra-Body Adiposity Estimator (CUN-BAE), and Deurenberg's formula), central adiposity (waist and neck circumferences, conicity index, waist to height ratio, Bonora's equation, A body adiposity index, and body roundness index), and lean body mass (Hume formula) were assessed. Irrespective of sex, lower indices of physical activity were associated with higher values of total body fat and central adiposity. This result was constant regardless of the indices used to estimate adiposity. However, the association between MedDiet and obesity indices was much less marked and more dependent on sex than that observed for physical activity. Lean body mass was influenced by neither physical activity nor MedDiet adherence. No joint effect between physical activity and MedDiet to lower estimated total or central adiposity indices was shown. In conclusion, physical activity is related to lower obesity indices in a large cohort of middle-aged subjects. MedDiet showed a slight impact on estimated anthropometric indices, with no joint effect when considering both lifestyle variables. ClinTrials.gov Identifier: NCT03228459.

Dietary changes during the Great Recession in Portugal: comparing the 2005/2006 and the 2014 health surveys.

OBJECTIVE: We aimed at analysing changes in consumption of selected food groups in the Portuguese population before and after the Great Recession, which hit the country between 2008 and 2013. DESIGN: We used pooled cross-sectional data from the Portuguese National Health Interview Surveys of 2005/2006 and 2014. We modelled the probability of consumption of soup, fish, meat, potatoes/rice/pasta, bread, legumes, fruit, vegetables and sweets/desserts, as a function of the year, controlling for age, sex and education, using logistic regressions. Then, we stratified the analysis by age group and education level. Analyses were adjusted for survey weights. SETTING: Portugal (2005/2006 to 2014).ParticipantsAdults (n 43273) aged 25-79 years. RESULTS: From 2005/2006 to 2014, there was a significantly lower consumption of fish, soup, fruit and vegetables. Conversely, the consumption of legumes and sweets/desserts was significantly higher in 2014. The changes in the selected food groups were consistent across most education levels. Among people aged 65 years or above, there were no significant changes in most foods, except an increase in the consumption of legumes and sweets/desserts. In contrast, people aged 25-39 and 40-64 years significantly decreased their intakes of fish and soup and increased their consumption of sweets/desserts. CONCLUSIONS: The consistent results across education levels suggest that changes in dietary habits are not linked to the economic downturn. By contrast, our findings suggest a shift away from foods commonly linked to the Mediterranean diet, particularly among younger people.

Socioeconomic and psychosocial determinants of adherence to the Mediterranean diet in a general adult Italian population.

BACKGROUND: To evaluate the adherence to Mediterranean diet (MD) and its major socioeconomic and psychosocial determinants in a large sample of the Italian population, covering three main geographical areas of the Country (Southern, Central and Northern). METHODS: Data were obtained from the Italian Nutrition & Health Survey (INHES), including a total of 7, 430 participants (age >20) recruited from all over Italy (2010-13). Dietary information was collected by the European Food Propensity Questionnaire. Adherence to MD was assessed by using the MedDietScore based on 11 food groups. Associations were tested by multivariable logistic regression analysis (Odds ratio [OR] with 95% CI). RESULTS: Adherence to MD was higher in Southern Italy as compared with the Northern (OR = 1.34; 95% CI 1.18-1.53), and was closely associated with adult age (OR= 2.40; 1.61-3.58 for those aged > 75 years as compared with 20-34 years) and higher educational level (OR = 1.77; 1.40-2.24 for post-secondary education as opposed to lowest educational attainment). Subjects reporting adverse life events and those with family-related stress were less likely to show an optimal adherence to MD (OR = 0.55; 0.46-0.67 and OR = 0.44; 0.28-0.69, for highest vs. lowest tertile, respectively) as compared with adequate controls. A number of eating behaviours were also inversely associated with MD, such as consuming higher amount of alcohol in the weekend than in week days. CONCLUSIONS: Adherence to MD is strongly determined by age, geographical area and educational level. Psychosocial factors and several eating behaviours are also closely associated.

Mediterranean diet, weight status and physical activity in schoolchildren of the Region of Murcia. / Dieta mediterránea, estado de peso y actividad física en escolares de la Región de Murcia.

INTRODUCTION: Childhood and adolescence are key stages to promote a healthy lifestyle. OBJECTIVE: To analyze the relationship between weight status, physical activity and the Mediterranean diet in schoolchildren in the Region of Murcia. METHODS: Cross-sectional descriptive study with 520 schoolchildren aged 8-17 years. The weight status was calculated through the body mass index. The Mediterranean diet was found through the KIDMED questionnaire and physical activity was estimated using the IPAQ-C and IPAQ-A questionnaires. RESULTS: The Mediterranean diet is not significantly associated with sex (P<.537) or weight status (P<.417) but it maintains a relationship of dependence with age (P<.010) and the level of physical activity (P<.000). Schoolchildren in normal weight and assets have a greater follow-up to the Mediterranean diet than their overweight and sedentary peers (P<.000). CONCLUSION: The Fat but fit phenomenon applied to the Mediterranean diet is confirmed.

[The Mediterranean diet as an example of food and nutrition sustainability: a multidisciplinary approach]. / La dieta mediterránea como ejemplo de una alimentación y nutrición sostenibles: enfoque multidisciplinar.

Sustainability represents a major concern in recent years due to climate change pressure. The diet itself contribute to the emission of greenhouse gasses, water and land use, energy consumption and environment contamination. The Mediterranean diet should be understood not only as a set of foods but also as a cultural model that involves the way foods are selected, produced, processed and distributed. The Mediterranean dietary pattern is presented not only as a cultural model but also as a healthy and environmentally friendly model. The recognition by UNESCO, with the consequent increased visibility and acceptance of the Mediterranean diet around the world, along with better and more scientific evidence regarding its benefits and effectiveness on longevity, quality of life and disease prevention, have taken this dietary pattern to an unprecedented historical moment. This is a favorable situation that could possibly enable the strengthening of the Mediterranean diet around the world, thus potentiating improvements in global health indicators and in a reduction of environmental impact by production and transportation of food resources. Therefore, the Mediterranean diet should be seen for what it is: an extremely and incomparable healthy, affordable and environmentally sustainable food model, as well as an ancient cultural heritage that confers identity and belonging. From the heart to the earth through the road of culture, the Mediterranean diet is a cultural heritage that looks to the future.

La sostenibilidad representa una gran preocupación en los últimos años debido a los efectos del cambio climático. La dieta, el uso del agua y de la tierra, el consumo de energía y la contaminación del medioambiente son elementos que contribuyen a la emisión de gases de efecto invernadero. La dieta mediterránea debe entenderse no solo como un conjunto de alimentos, sino también como un modelo cultural que involucra la forma en que los alimentos se seleccionan, producen, procesan y distribuyen. El patrón dietético mediterráneo se presenta no solo como un modelo cultural, sino también como un modelo ecológico.El reconocimiento de la Unesco, con la consiguiente mayor visibilidad y aceptación de la dieta mediterránea en todo el mundo y el mayor número de evidencias científicas sobre sus beneficios y efectividad en cuanto a la longevidad, calidad de vida y prevención de enfermedades, han llevado a este patrón dietético a un nivel sin precedentes. Esta es una situación favorable que, posiblemente, podría permitir el fortalecimiento de la dieta mediterránea en todo el mundo, potenciando mejoras en los indicadores de salud mundial y en la reducción del impacto ambiental por la producción y transporte de los recursos alimentarios.Por ello, la dieta mediterránea debe ser vista como un modelo alimentario saludable, asequible y ambientalmente sostenible, así como un patrimonio cultural antiguo que confiere identidad y pertenencia. Del corazón a la tierra a través del camino de la cultura, la dieta mediterránea es un patrimonio cultural que mira hacia el futuro.

Mediterranean diet, diet quality, and bone mineral content in adolescents: the HELENA study.

Dietary scores, rather than individual nutrients, allow exploring associations between overall diet and bone health. The aim of the present study was to assess the associations between the Mediterranean Diet Score for Adolescents (MDS-A) and the Diet Quality Index for Adolescents (DQI-A) and bone mineral content (BMC) among Spanish adolescents. Our results do not support an association between dietary scores or indices and BMC in adolescents. INTRODUCTION: To assess the associations between the MDS-A and a DQI-A with the BMC measured with dual-energy X-ray absorptiometry. METHODS: The MDS-A and the DQI-A were calculated in 179 Spanish adolescents, based on two 24-h dietary recalls from the HELENA cross-sectional study. The associations between the diet scores and the BMC outcomes [total body less head (TBLH), femoral neck (FN), lumbar spine (LS), and hip] were analyzed using logistic regression models adjusting for several confounders. RESULTS: Four hundred ninety-two models were included and only fruits and nuts and cereal and roots were found to provide significant ORs with regard to BMC. The risk of having low BMC reduced by 32% (OR 0.684; CI 0.473-0.988) for FN when following the ideal MDS-A, but this association lost significance when adjusting for lean mass and physical activity. For every 1-point increase in the cereal and root and the fruit and nut components, the risk of having low FN diminished by 56% (OR 0.442; CI 0.216-0.901) and by 67% (OR 0.332; CI 0.146-0.755), respectively. CONCLUSION: An overall dietary score or index is not associated with BMC in our adolescent Spanish sample.

The association between healthy lifestyle behaviors and health-related quality of life among adolescents / Associação entre comportamentos de estilo de vida saudável e a qualidade de vida relacionada à saúde entre adolescentes

Abstract Objective: The aim of this research was to examine the association between body mass index, physical activity, adherence to the Mediterranean diet, and health-related quality of life in a sample of Spanish adolescents. Method: The study involved 456 adolescents aged between 11 and 14 years. They completed questionnaires on the Mediterranean diet (KIDMED), physical activity (Physical Activity Questionnaire for Older Children [PAQ-C]), and quality of life (KIDSCREEN-27). Body mass index was calculated. Hierarchical linear regression analyses were used to determine whether health-related quality of life could be predicted by the measured variables. The variables were analyzed in a stepwise manner, with Mediterranean diet entered in the first step, body mass index in the second, and physical activity in the third. Results: Mediterranean diet accounted for 4.6% of the variance in adolescent's health-related quality of life, with higher adherence to the Mediterranean diet predicting higher health-related quality of life-scores. Body mass index accounted for a further 4.1% of the variance, with a higher body mass index predicting lower health-related quality of life scores. Finally, physical activity explained an additional 11.3% of the variance, with a higher level of physical activity being associated with higher health-related quality of life scores. Together, these variables explained 20% of the variance in the adolescents' health-related quality of life. Conclusions: Physical activity, body mass index, and adherence to the Mediterranean diet are important components to consider when targeting improvements in the health-related quality of life of adolescents, with physical activity representing the component with the greatest influence.

Resumo Objetivo: O objetivo desta pesquisa foi examinar a associação entre o índice de massa corporal, a atividade física, a adesão à dieta mediterrânea e a qualidade de vida relacionada à saúde em uma mostra de adolescentes espanhóis. Método: O estudo envolveu 456 adolescentes entre 11 e 14 anos. Eles preencheram questionários sobre a dieta mediterrânea (Kidmed), atividade física (Questionário de Atividade Física para Crianças mais velhas, PAQ-C) e qualidade de vida (Kidscreen-27). Foi calculado o índice de massa corporal. Análises de regressão linear hierárquica foram usadas para determinar se a qualidade de vida relacionada à saúde pode ser prevista pelas variáveis medidas. As variáveis foram introduzidas de forma gradual com a dieta mediterrânea na primeira etapa, índice de massa corporal na segunda etapa e atividade física na terceira. Resultados: A dieta mediterrânea representou 4,6% da variância na qualidade de vida relacionada à saúde dos adolescentes e uma maior adesão à dieta mediterrânea foi preditiva de maiores escores de qualidade de vida relacionados à saúde. O índice de massa corporal representou um adicional de 4,1% de variância e um maior índice de massa corporal foi preditivo de menores escores de qualidade de vida relacionada à saúde. Por fim, a atividade física representou um adicional de 11,3% da variância e um maior nível de atividade física foi associado a maiores escores de qualidade de vida relacionada à saúde. Juntas, essas variáveis representam 20% da variância na qualidade de vida relacionada à saúde dos adolescentes. Conclusões: A atividade física, o índice de massa corporal e a adesão à dieta mediterrânea são importantes componentes para considerar ao visar melhorias na qualidade de vida relacionada à saúde dos adolescentes, a atividade física é o componente com maior influência.
