Introduction: eating behaviors may modulate or influence diet quality and the degree of adherence to the Mediterranean diet in children andadolescents.Aims: to investigate the association between diet quality and eating behavior in a group of Spanish schoolchildren.Methods: descriptive cross-sectional study of 283 Spain schoolchildren aged six to 16. Each subject was assessed using the KIDMED question-naire for adherence to the Mediterranean diet and the Children’s Eating Behaviour Questionnaire (CEBQ) questionnaire to assess eating behavior.Results: of the sample, 12.80 % had low adherence to the Mediterranean diet, 59.80 % had poor adherence, 59.80 % could be improved, and27.40 % had high adherence. When relating eating behavior to dietary quality, it was found that, generally, schoolchildren with greater enjoymentof food and less demand for food have double the adherence to the Mediterranean diet due to almost twice the consumption of vegetables,nuts, and fish, and a lower intake of low-quality processed foods (sweets). The response to satiety and the speed of ingestion also played animportant role in food choices.Conclusions: eating behaviors may play an essential role in the quality of school children’s diets highlighting the enjoyment and acceptance orrejection of food.

Beneficial Effects of Olive Oil Enriched with Lycopene on the Plasma Antioxidant and Anti-Inflammatory Profile of Hypercholesterolemic Patients.

Olive oil and lycopene are foods that have potent antioxidant activity. The objective was to determine the effects of consumption of olive oil enriched with lycopene on oxidative stress biomarkers in hypercholesterolemic subjects. We examined the effects of oil enriched with lycopene extract daily intake during 1 month on plasma antioxidant capacity, lipids profile (triacylgycerols, total cholesterol, cHDL; cLDL, ox-LDL), biomarkers of oxidative stress, and inflammatory markers related with atherosclerosis risk (C-reactive protein (CRP), IL-6; sDC4L) in subjects hypercholesteremics (cholesterol > 220 mg/dL). In the group consuming olive oil-lycopene, significant increases (p < 0.05) in the levels of plasma lycopene concentration (0.146 ± 0.03 versus 0.202 ± 0.04 (µmol/L)), α-carotene (0.166 ± 0.064 versus 0.238 ± 0.07) and in ß-carotene (0.493 ± 0.187 versus 0.713 ± 0.221) were observed. These results are linked with the increases of plasma antioxidants and decreases biomarkers of oxidative stress (carbonyl groups, malondialdehyde and 8-hydroxy-deoxiguanosine) observed in hypercholesterolemic group. In relation to lipid profile, a significant decrease was observed in the levels of ox-LDL (781 ± 302 versus 494 ± 200), remaining unchanged the levels of TG, cholesterol, HDL and LDL-c. Regarding inflammatory biomarkers, the levels of CRP and IL-6 decreased significantly. The positive results obtained in this study support the use of olive oil enriched with lycopene to reduce the risk of coronary disease.

Fatigue, Work Overload, and Sleepiness in a Sample of Spanish Commercial Airline Pilots.

Commercial aviation pilots are an occupational group that work in particular conditions, with frequent schedule changes, shift work, unfavorable environmental conditions, etc. These circumstances can lead to fatigue, work overload (WO), and daytime sleepiness, factors that can affect their health and safety. This study aimed to assess the prevalence and the association between these parameters in a sample of Spanish commercial airline pilots. The Raw TLX, Fatigue Severity Scale, and the Epworth Sleepiness Scale questionnaires were administered in a sample of 283 participants. The relationships of the total scores between all the questionnaires were studied by the chi-square test and the risk scores (odds ratio) were calculated. Different models using multiple linear regression were carried out to evaluate the effects of WO, fatigue, and daytime sleepiness, among the total scores, age, and flight hours. Additionally, the internal consistency of each questionnaire was estimated. A total of 28.2% presented WO above the 75th percentile, with mental and temporal demand the dimensions with the greatest weight. A total of 18% of pilots presented fatigue, 15.8% moderate sleepiness, and 3.9% severe sleepiness. We observed an association among WO, fatigue, and daytime sleepiness, important factors related to pilot health and aviation safety.

Genetic risk score for common obesity and anthropometry in Spanish schoolchildren.

IntroductionCommon or non-syndromic obesity is a complex polygenic trait conditioned by biallelic or single-base polymorphisms called SNPs (Single-Nucleotide Polymorphisms) that present an additive effect and act synergistically. Most genotype-obese phenotype association studies include body mass index (BMI) or waist-to-height ratio (WtHR), and very few introduce a broad anthropometric profile. ObjectiveTo verify whether a genetic risk score (GRS) developed from 10 SNPs is associated with the obesity phenotype assessed from anthropometric measures indicative of excess weight, adiposity and fat distribution. Material and methodsA series of 438 Spanish schoolchildren (6-16 years old) were evaluated anthropometrically (weight, height, waist circumference, skinfold thickness, BMI, WtHR, body fat percentage [%BF]). Ten SNPs were genotyped from saliva samples, generating a GRS for obesity, establishing genotype-phenotype association. ResultsSchoolchildren categorised as obese by BMI, ICT and %BF had higher GRS than their non-obese peers. The prevalence of overweight and adiposity was higher in subjects with a GRS above the median. Similarly, between 11 and 16 years of age, all anthropometric variables presented higher averages. ConclusionsGRS estimated from the 10 SNPs can be a diagnostic tool for the potential risk of obesity in Spanish schoolchildren and could be useful from the preventive perspective.

Eating Behavior and Obesity in a Sample of Spanish Schoolchildren.

From the point of view of prevention, it is convenient to explore the association between eating behavior and the obese phenotype during school and adolescent age. The aim of the present study was to identify eating behavior patterns associated with nutritional status in Spanish schoolchildren. A cross-sectional study of 283 boys and girls (aged 6 to 16 years) was carried out. The sample was evaluated anthropometrically by Body Mass Index (BMI), waist-to-height ratio (WHtR) and body fat percentage (%BF). Eating behavior was analyzed using the CEBQ "Children's Eating Behavior Questionnaire". The subscales of the CEBQ were significantly associated with BMI, WHtR and %BF. Pro-intake subscales (enjoyment of food, food responsiveness, emotional overeating, desire for drinks) were positively related to excess weight by BMI (ß = 0.812 to 0.869; p = 0.002 to <0.001), abdominal obesity (ß = 0.543-0.640; p = 0.02 to <0.009) and high adiposity (ß = 0.508 to 0.595; p = 0.037 to 0.01). Anti-intake subscales (satiety responsiveness, slowness in eating, food fussiness) were negatively related to BMI (ß = -0.661 to -0.719; p = 0.009 to 0.006) and % BF (ß = -0.17 to -0.46; p = 0.042 to p = 0.016).

Atherogenic Risk, Anthropometry, Diet and Physical Activity in a Sample of Spanish Commercial Airline Pilots.

Cardiovascular accidents are the most disabling event for pilots, causing complicated situations during flight and the withdrawal of license. The study aims to assess the modifiable risk factors and the atherogenic index of plasma (AIP) associated with anthropometric, physiometabolic and lifestyle profiles in a sample of Spanish aviation pilots. Data from pilots' clinical and professional history, anthropometric and bioelectrical impedance assessments of nutritional status, and diet and physical activity questionnaires. The sample comprised 304 men pilots. Up to 53.6% showed excess weight, of which 6.4% were obese, 64.3% presented high relative adiposity and 64.6% showed abdominal obesity. Regarding the physiometabolic profile, 10.0% had hypertension, 42.6% hypercholesterolemia, 9.4% high LDL and 10.6% low HDL, 9.4% hyperglycemia and 8.1% hypertriglyceridemia. The adherence to the Mediterranean diet (MedDiet) was high in 29.7% and low in 14.7%. Most of the sample showed a good physical activity level. The AIP risk increased with higher obesity indicators and LDL cholesterol levels. There was an inverse relationship between the MedDiet adherence and vigorous physical activity and the risk of atherogenicity. Elevated rates of overweight, abdominal obesity and hypercholesterolemia were found, contributing to the atherogenic risk of plasma (AIP). This parameter was significantly associated with all anthropometric indicators and LDL cholesterol. Prevention plans on reducing excess fat and blood cholesterol levels are recommended to reduce cardiovascular risk in Spanish aviation pilots and ensure flight safety.

Growth patterns of normo-nourished Afghan, Haitian and Congolese children aged 6-59 months: A comparative study.

OBJECTIVES: International growth charts have been used in the past decades to identify atypical growth and diagnose the nutritional status of individuals. The aim of this study was to construct and compare growth patterns of normo-nourished children between 6-59 months from Afghanistan, Haiti, and the Democratic Republic of the Congo, to assess if it would be worth developing growth charts at a national level. METHODS: We used an international sample of 46 466 subjects (53.7% female; 46.3% male) from the aforementioned regions. To create the growth charts, we used different statistical methodologies: the Lambda-Mu-Sigma (LMS), LMSP, and LMST models, and regression models based on fractional polynomials. The LMSP models were the ones that fitted our data best and were therefore the ones used to make comparisons between countries using percentiles (3rd, 50th, and 97th). RESULTS: We found that Haitian children were both, taller and heavier than their Afghan and Congolese equals of the same ages. Moreover, differences were bigger in the highest percentiles (i.e., 97th percentile). These differences might be the result of the influence that genetics and diverse social and environmental contexts have on growth rates. CONCLUSIONS: Using the same international reference standards for all populations could result in the overestimation or underestimation of the proportion of malnourished children. In light of our results, we recommend the future development of national and regional growth charts to provide health workers with more precise tools to evaluate the nutritional status in the child population.

Condición nutricional y hábitos alimentarios de los asistentes a consulta de nutrición en España dentro del ámbito laboral / Nutritional conditions and eating habits of those attending a Spain nutritional consultation within the workplace

Introducción: Los hábitos alimentarios y la condición nutricional de los trabajadores debe plantearse desde los propios centros de trabajo, con el objetivo de promover un estilo de vida saludable en prevención de patologías crónicas y en mejora de la calidad de vida. Objetivos: conocer la condición nutricional de una muestra de trabajadores de una empresa, junto a su grado de ad-herencia a la dieta mediterránea y otros factores relacionados con el estilo de vida. Material y métodos: es un estudio descriptivo transversal con 634 trabajadores que asistieron voluntariamente a consulta de un Dietista-Nutricionista dentro de su empresa. Se valoró: la condición nutricional mediante antropometría e impedancia, la adherencia a la dieta mediterránea por PRE-DIMED, y analíticas sanguíneas.

El 29,34% tenía baja adherencia a la dieta mediterránea, estando asociada a un mayor índice de masa corporal y a elevada adiposidad relativa (p<0,001). El 39,27% eran sedentarios, coincidiendo con aquellos que tenían un índice de cintura talla e IMC más elevado. Conclusiones: La prevalencia de sobrepeso y obesidad fue elevado, especialmente en hombres. Una mayor adherencia a la dieta mediterránea según el cuestionario PREDIMED, y mayor práctica de actividad física se asoció a mejor condición nutricional en general. Se destaca la importancia de la figura del Dietista-Nutricionista en las empresas para una adecuada educación alimentaria. (AU)

Background: Feeding habits and nutritional condition of workers must be considered in the workplace, with the aim of promoting a healthy lifestyle in preventing chronic diseases and improving the quality of life. Objectives: to know the nutritional status of a sample of workers in a company, along with their degree of adherence to the Mediterranean diet and other factors related to lifestyle. Methods: It is a cross-sectional descriptive study based on the data collection of 634 workers who voluntarily attended the consultation of a Dietitian-Nutritionist within your company. It has been evaluated: the nutritional status, adheren ceto the Mediterranean diet by the PREDIMED questionnaire, and other factors such as life style, blood tests and related pathologies. Results: The main reason for consultation was the nutritional assessment followed by weight loss and hypercholesterolemia. 55.21% of the sample had excess weight (40.22% overweight and 14.99% obesity) according to the BMI; 62.15% had an ICT> 0.50; 64.04% excess body fat according to Bray (17) and 55.52% according to Gallagher (18). In addition, 29.34% had low adherence to the Mediterranean diet. Subjects with less adherence to this dietary pattern had higher BMI (P = 0.007) and percentage of body fat according to Bray (p = 0.007). 39.27% were sedentary, coinciding with those who had higher ICT (0.002) andhigher BMI (p = 0.003). Conclusion: the prevalence of overweight and obesity was alarmingly high, especially in men. Greater adherence to the Mediterranean diet according to the PREDIMED questionnaire and greater practice of physical activity was associated with a better nutritional condition in general. The importance of the figure of the Dietitian-Nutritionist in the companies for a greater nutritional education stands out. (AU)

The Different Microbial Etiology of Prosthetic Joint Infections according to Route of Acquisition and Time after Prosthesis Implantation, Including the Role of Multidrug-Resistant Organisms.

The aim of our study was to characterize the etiology of prosthetic joint infections (PJIs)-including multidrug-resistant organisms (MDRO)-by category of infection. A multicenter study of 2544 patients with PJIs was performed. We analyzed the causative microorganisms according to the Tsukayama's scheme (early postoperative, late chronic, and acute hematogenous infections (EPI, LCI, AHI) and "positive intraoperative cultures" (PIC)). Non-hematogenous PJIs were also evaluated according to time since surgery: <1 month, 2-3 months, 4-12 months, >12 months. AHIs were mostly caused by Staphylococcus aureus (39.2%) and streptococci (30.2%). EPIs were characterized by a preponderance of virulent microorganisms (S. aureus, Gram-negative bacilli (GNB), enterococci), MDROs (24%) and polymicrobial infections (27.4%). Conversely, coagulase-negative staphylococci (CoNS) and Cutibacterium species were predominant in LCIs (54.5% and 6.1%, respectively) and PICs (57.1% and 15.1%). The percentage of MDROs isolated in EPIs was more than three times the percentage isolated in LCIs (7.8%) and more than twice the proportion found in AHI (10.9%). There was a significant decreasing linear trend over the four time intervals post-surgery for virulent microorganisms, MDROs, and polymicrobial infections, and a rising trend for CoNS, streptococci and Cutibacterium spp. The observed differences have important implications for the empirical antimicrobial treatment of PJIs.

Valoración del estado nutricional y de hábitos y preferencias alimentarias en una población infanto-juvenil (7 a 16 años) de la Comunidad de Madrid / Assessment of nutritional status, and habits and food preferences in a child-youth population (7 to 16 years) of the Community of Madrid

Introducción: la prevalencia de sobrepeso y obesidad en la infancia y adolescencia en España es alarmante. El alto consumo de productos procesados de baja calidad nutricional pero alta densidad calórica, junto al sedentarismo, son dos de las principales causas. Objetivos: conocer la condición nutricional de una población de niños y adolescentes, y algunos de sus hábitos alimentarios, gustos y preferencias y práctica de actividad física. Métodos: estudio descriptivo transversal basado en una valoración antropométrica y encuesta sobre hábitos alimentarios y estilo de vida a 1.939 escolares de entre siete y 16 años de centros escolares de la Comunidad de Madrid.

Background: the prevalence of overweight and obesity in childhood and adolescence in Spain is alarming. The high consumption of processed products of low nutritional quality but high caloric density, together with sedentary lifestyle, are two of the main causes. Objective: to know the nutritional status of a population of children and adolescents, and some of their eating habits, tastes and preferences, and physical activity practice. Methods: a cross-sectional descriptive study based on an anthropometric assessment and a survey on food habits and lifestyle in 1,939 schoolchildren between seven and 16 years of school age in the Community of Madrid. Updated indexes such as the body mass index (BMI) adapted according to the Cole cut-off points and the waist-height index (CTI), which have a high correlation with infant adiposity, are used. Results: the rates of overweight and obesity are high in both children and adolescents. It should be noted that abdominal obesity according to ICT represents a greater percentage than global obesity diagnosed with BMI (overweight + total obesity according to BMI: 27.23%, and according to ICT: 35.17%). The sedentariness is high (25.12%), as well as the consumption of highly caloric products, but of low nutritional value mainly at breakfast, mid-morning and snack. Conclusions: the prevalence of overweight and obesity is high, especially at the abdominal level, probably associated with the increasing consumption of ultra-processed products and the high rates of sedentary lifestyle. The conclusion is the need to develop programs to prevent obesity and nutritional education

Probabilistic risk analysis of mercury intake via food consumption in Spain.

In Spain, recently, the public institutions have given information to the population in relation to fish consumption and the risk that it poses to health from the ingestion of mercury supposedly contained in the fish. At the same time, several scientific societies have published various works in this direction. All this without there being, up to now, any study on the evaluation of a probabilistic risk from mercury due to fish and seafood intake in Spain, which is the objective of this present work. For that purpose, we took individual data from a survey of the total diet of 3000 people, whose consumption of the principal fish and seafood species (49) was estimated. We compiled individualized data (2000) on the total mercury content of those species, which were completed and validated with bibliographic statistical data. After estimating the distributions of each fish and seafood species, both of their consumption and their mercury content, a simulation was made of the distribution of mercury ingestion from fish and seafood offered by 2.6% of the Spanish population at risk of exceeding total mercury recommendations, and between 12.2% and 21.2% of those exceeding methylmercury ones. The main species responsible were tuna fish, swordfish and hake, and significant differences were identified in fish consumption between sexes and ages, although, in the risk percentage, what stands out is an increase in the latter with an increase in age.

Consensus document on the prevention of methylmercury exposure in Spain: Study group for the prevention of Me-Hg exposure in Spain (GEPREM-Hg).

The beneficial effects of fish consumption in both children and adults are well known. However, the intake of methylmercury, mainly from contaminated fish and shellfish, can have adverse health effects. The study group on the prevention of exposure to methylmercury (GEPREM-Hg), made up of representatives from different Spanish scientific societies, has prepared a consensus document in a question and answer format, containing the group's main conclusions, recommendations and proposals. The objective of the document is to provide broader knowledge of factors associated with methylmercury exposure, its possible effects on health amongst the Spanish population, methods of analysis, interpretation of the results and economic costs, and to then set recommendations for fish and shellfish consumption. The group sees the merit of all initiatives aimed at reducing or prohibiting the use of mercury as well as the need to be aware of the results of contaminant analyses performed on fish and shellfish marketed in Spain. In addition, the group believes that biomonitoring systems should be set up in order to follow the evolution of methylmercury exposure in children and adults and perform studies designed to learn more about the possible health effects of concentrations found in the Spanish population, taking into account the lifestyle, eating patterns and the Mediterranean diet.

Eating habits and preferences among the student population of the Complutense University of Madrid.

OBJECTIVE: Studying eating habits can aid in the design of specific measures that reduce the negative effects of an unhealthy diet on health. In this context, the aim of the present study was to examine the eating habits and food preferences of students and their level of satisfaction with the catering services of the university. DESIGN: Survey conducted during 2011 using a questionnaire that asked participants abut their sex, age and frequency of use of catering services placed on campus. Participants were also asked about their level of satisfaction with five aspects (hygiene, quality, taste of food, price and convenience of facilities) of the university catering services, what their preferred dishes were and whether they followed a special diet. SETTING: Complutense University of Madrid, Spain. SUBJECTS: Nine hundred and sixty-four students (381 males; 583 females). RESULTS: The students used the university food service 2·3 (sd 1·3) times/week. With respect to satisfaction level, 44·1 % gave an average score (3) to the combination of surveyed aspects (hygiene, quality, taste of food, price and comfort of the dining rooms). Regarding food choices, 61·0 % of students preferred pasta dishes, followed by meat (59·1 %) and salads (32·5 %). The least popular dishes were vegetables (16·8 %), fruits (13·6 %), milk products (12·2 %) and legumes (9·8 %). Of the students, 20·1 % followed special diets. CONCLUSIONS: The degree of satisfaction with the university meal service was low and the most common choices of dishes and foods among students were far from the guidelines of the Mediterranean diet. It is necessary to extend policies related to diet to this sector of the population and also to the management and food offer of university canteens.

Metilmercurio: Recomendaciones existentes; métodos de análisis e interpretación de resultados; evaluación económica / Methylmercury: existing recommendations; methods of analysing and interpreting the results; economic evaluation

Los efectos beneficiosos del consumo de pescado son bien reconocidos. Sin embargo, existe preocupación a nivel mundial sobre los niveles de metilmercurio en el pescado, por lo que muchos países como Estados Unidos, Australia, Nueza Zelanda, Canadá y muchos países europeos han realizado recomendaciones de consumo de pescado a la población , especialmente a los grupos vulnerables con el fin de reducir la ingesta de metilmercurio. La sangre y el pelo son las mejores muestras biológicas para medir el metilmercurio. El método de análisis más empleado ha sido la espectroscopia de absorción atómica con la técnica del vapor frío, aunque existen también métodos directos que se basan en la descomposición térmica de la muestra. En los últimos años han aumentado los laboratorios que miden el mercurio por espectrometría de masas con plasma acoplado por inducción. Además, se puede diferenciar las distintas especies de mercurio acoplando métodos de separación cromatográficos. Es necesario que los laboratorios que analizan mercurio en muestras biológicas participen en programas de garantía externa de la calidad. Aunque se logre reducir las emisiones de mercurio, el mercurio del medio ambiente altodavía puede permanecer muchos años, por lo que es fundamental el consejo dietético para disminuir la exposición. No es aconsejable el uso de terapia quelante con fines diagnósticos o en pacientes asintomáticos. Es preciso proponer medidas de salud pública encaminadas a la disminución de la exposición al mercurio y que se evalúe también los beneficios de las mismas desde el punto de vista económico y social (AU)

The beneficial effects of fish consumption are well-known. Nevertheless, there is worldwide concern regard methylmercury concentrations in fish, which is why many countries such as the United States, Australia, New Zealand, Canada and numerous European countries have made fish consumption recommendations for their populations, particularly vulnerable groups, in order to México methylmercury intake. Blood and hair are the best biological samples for measuring methylmercury. The most widely-used method to analyse ethylmercury is cold vapor atomic absorption spectrometry, although there are also direct methods based on the thermal decomposition of the sample. In recent years, the number of laboratories that measure mercury by inductively coupled plasma mass spectrometry has increased. In addition, the different kinds of mercury can be distinguished by coupling chromatography methods of separation. Laboratories that analyse mercury in biological samples need to participate in external quality control programmes. Even if mercury emissions are reduced, mercury may remain in the environment for many years, so dietary recommendations are fundamental in order to reduce exposure. It is necessary to propose public health measures aimed at decreasing mercury exposure and to evaluate the benefits of such measures from the economic and social standpoints (AU)
