Background/Objectives: Indices predictive of central obesity include waist circumference (WC) and waist-to-height ratio (WHtR). These data are lacking for Colombian adults. This study aims at establishing smoothed centile charts and LMS tables for WC and WHtR; appropriate cutoffs were selected using receiver-operating characteristic analysis based on data from the representative sample. Subjects/Methods: We used data from the cross-sectional, national representative nutrition survey (ENSIN, 2010). A total of 83 220 participants (aged 20-64) were enroled. Weight, height, body mass index (BMI), WC and WHtR were measured and percentiles calculated using the LMS method (L (curve Box-Cox), M (curve median), and S (curve coefficient of variation)). Receiver operating characteristics curve analyses were used to evaluate the optimal cutoff point of WC and WHtR for overweight and obesity based on WHO definitions. Results: Reference values for WC and WHtR are presented. Mean WC and WHtR increased with age for both genders. We found a strong positive correlation between WC and BMI (r=0.847, P [less than] 0.01) and WHtR and BMI (r=0.878, P [less than] 0.01). In obese men, the cutoff point value is 96.6 cm for the WC. In women, the cutoff point value is 91.0 cm for the WC. Receiver operating characteristic curve for WHtR was also obtained and the cutoff point value of 0.579 in men, and in women the cutoff point value was 0.587. A high sensitivity and specificity were obtained. Conclusions: This study presents first reference values of WC and WHtR for Colombians aged 20-64. Through LMS tables for adults, we hope to provide quantitative tools to study obesity and its complications.

- Abstract
Background: Waist circumference has been suggested as predictor for metabolic syndrome (MetS) in adolescents but it has not been compared with newly proposed anthropometric indexes. This study aimed to disclose the capacity of ten classic and novel anthropometric indexes to discriminate by the presence of MetS in this young population. Materials and methods: A cross-sectional study was performed on 981 adolescents (13.2 ± 1.2 years) randomly recruited from eighteen schools in south-east Spain. Body fat percentage (BF%), abdominal volume index (AVI), body roundness index (BRI), body mass index (BMI), body adiposity index (BAI), body adiposity index for paediatrics (BAIp), conicity index (C-Index), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and body shape index (ABSI) were measured and calculated. Receiver-operator curves (ROC) were created to determine the discriminatory capacity of these anthropometric parameters for MetS. Results: The prevalence of MetS was 7.0% for boys and 6.1% in girls. Participants with MetS had significantly higher levels of blood pressure and plasma levels of lipids, glucose and insulin. All anthropometric indexes were elevated in MetS individuals compared to the non-MetS group. AVI and WC showed the highest AUC values (0.83 for boys and 0.86 for girls). In contrast, according to ROC analyses, no anthropometric index was capable of discriminating the components of MetS (hypertension, hypertriglyceridemia, hyperglycaemia and low-HDL levels), except for abdominal obesity. Conclusion: We suggest the use of WC and AVI, with the cut-off points presented herein, for the discrimination between adolescents with or without MetS.

Obesity is the result of a positive balance between total energy intake and its catabolism. Although many factors are involved in the regulation of energy metabolism, the discovery of leptin led to energy homeostasis being investigated in greater depth. Since its identification, leptin has been considered important in the development of obesity, given its anorexigenic effect and influence on food intake and energy expenditure. Leptin is involved in diverse physiological processes such as energy balance, appetite and body weight control, fat and carbohydrate metabolism, and reproduction. However, to be able to function, this hormone has many specific receptors both centrally (hypothalamus) and peripherally in the skeletal muscle, lungs and kidneys. This study aims to review the key aspects relating leptin to the development of obesity and discusses its potential as an anorectic agent.

Introduction: This study aimed to analyze the nutritional status among Colombian children and adolescents and to determine the relationship between the nutritional status according to the body mass index (BMI) and the waist circumference (WC). Methods: A cross-sectional study was conducted in 6.383 children and adolescents with age of 9 to 17.9 years old from Bogota, Colombia. Participants completed the Krece Plus questionnaire validated by the enKid study as an indicator of the nutritional level with the following categories: high (test ? 9), medium (test 6-8) and low (test ? 5). Other measures were: weight, height, WC and BMI as markers of the nutritional status. Results: Overall, 57.9% of the participants were girls (mean age 12.7 ± 2.3 years old). The nutritional status was low without large differences by sex and decreasing by age. In all categories of BMI, over 50% of boys and girls follow lower-quality diet, shown worse with advancing age. In both sexes, trends were observed between low nutritional level with the development of overweight. Also, WC was associated with a lower score in the Krece Plus in both sexes. Conclusions: The low nutritional level is related to changes in the nutritional status (WC and BMI) in scholars from Bogota. These findings may encourage further interventions for the improvement of nutritional habits among scholars from Colombia. © 2016, Grupo Aula Medica S.A. All rights reserved.

[EN] Also known as ferroxidase ceruloplasmin, belongs to the family of inflammation-sensitive proteins, and its main function to transport copper in the blood. Although, in addition to this transport function, at present, there are numerous studies that have attempted to use the determination of serum concentrations as a predictive indicator of cardiovascular risk in patients who are overweight or obese. The results of this study confirm the existence of a significant correlation between serum ceruloplasmin and nutritional status of the subjects, which means that for the population of students assessed, serum levels of this protein are an important predictor the risk of cardiovascular disease., [ES] La ceruloplasmina también conocida como ferroxidasa, pertenece a la familia de las proteínas sensibles a la inflamación, siendo su función principal la de transportar el cobre en la sangre. Si bien, además de esta función transportadora, en la actualidad, son numerosos los estudios que han intentado hacer uso de la determinación de sus concentraciones séricas, como un indicador predictivo del riesgo de padecer trastornos cardiovasculares en pacientes que presentan sobrepeso u obesidad. Los resultados obtenidos en este estudio confirman la existencia de una correlación significativa entre los niveles séricos de ceruloplasmina y el estado nutricional de los sujetos, lo que significa que para la población de escolares valorada, las concentraciones séricas de esta proteína suponen un importante factor para predecir el riesgo de padecer trastornos cardiovasculares.

Introducción: En España la prevalencia de obesidad muestra un patrón de distribución norte-sur. En la provincia de Granada se desconoce su distribución. Objetivos: Los objetos del presente trabajo son estudiar la prevalencia de sobrepeso y obesidad en una población de escolares representativa de toda la provincia de Granada. Verificar diferencias significativas entre las comarcas de la provincia. Comprobar una correlación entre el estado nutricional de los alumnos y el de sus progenitores. Métodos: 977 escolares de entre 9 y 17 años de edad, pertenecientes a 13 centros educativos públicos de la provincia de Granada (España). Estudio analítico y multicéntrico, en el que se realizó una valoración del estado nutricional mediante antropometría. Además, mediante un cuestionario, se evaluó la existencia de antecedentes familiares de sobrepeso u obesidad. Resultados: Se encontró una elevada prevalencia de sobrepeso y obesidad entre la población estudiada. En chicas, la mayor prevalencia tanto de sobrepeso como de obesidad se situaba entre los 12 y los 14 años de edad. En los chicos, se observó un repunte en la prevalencia de sobrepeso a los 12 años. Respecto de la obesidad, sus tasas fueron considerablemente inferiores a las descritas entre las chicas. Se encontraron diferencias estadísticamente significativas para el peso (F = 4,154; p = 0,003), pero no para la estatura (F = 1,928; p = 0,105). En cambio, para la variable IMC se observaron diferencias estadísticamente significativas (F = 5,037; p < 0,001) entre las diferentes comarcas geográficas estudiadas. Aquellos alumnos con antecedentes familiares de obesidad mostraron un significativo (p < 0,01) peor estado nutricional. Discusión: Existe una elevada prevalencia de obesidad, especialmente entre las chicas. Existe un patrón de distribución geográfico posiblemente derivado de las características socioeconómicas de cada comarca. La existencia de antecedentes familiares de obesidad constituye un factor determinante para su desarrollo entre los jóvenes. Background: In Spain the prevalence of obesity shows a north-south distribution. In the province of Granada its distribution is unknown. Objectives: (1) To study the prevalence of overweight and obesity in a sample population of school children and adolescents from different districts in the province of Granada. (2) To verify whether there are significant differences, depending on the district where the students reside. (3) To find a possible correlation between the nutritional state of the students and that of their parents. Methods: The population sample was composed of 977 school children and adolescents from 9 to 17 years of age, attending 13 public elementary schools and high schools in the city and province of Granada (Spain). In this analytical and multicentric study, the nutritional state of the subjects was evaluated by means of anthropometric measurements. Furthermore, data were collected by means of questionnaire to discover whether the respondents had a family history of overweight or obesity. Results: We found a high prevalence of overweight and obesity among the studied population. In girls, the greater prevalence of both overweight and obesity ranged from 12 to 14 years of age. In boys, there was an increase in the prevalence of overweight at twelve years of age. Regarding obesity, their rates were significantly lower than those described among girls. There were statistically significant differences for weight (F = 4,154; p = 0,003) but not for height (F = 1,928; p =0,105). But for the variable BMI was statistically significant difference (F = 5.037; P < 0.001) between the studied geographical areas. The results showed that the nutritional state of students with a family history of obesity was significantly worse (p < 0.01). Discussion: A high prevalence of obesity was found in the sample, especially among the girls. There exists a geographical distribution pattern, possibly derived from the socioeconomic characteristics of each area in the province. The existence of a family history of obesity is an important factor that can determine whether the child will also become obese in the future.

La regulación de la ingesta energética representa un proceso de vital importancia en el organismo ya que posibilita el mantenimiento de un equilibrio entre la cantidad de energía almacenada en forma de grasa corporal y el catabolismo de la misma. Objetivo: El objetivo de este trabajo ha sido analizar los principales factores implicados en la regulación de la ingesta alimentaria, el balance energético y su fisiopatología. Metodología: Se realizó una búsqueda en Medline y Ebsco de artículos publicados en inglés y español en el período comprendido entre enero de 2009 y enero de 2012. Los términos de búsqueda fueron "food intake", "energy balance", "regulation", "nutritional homeostasis". Resultados: Se encontraron un total de 198 estudios científicos, de los cuales únicamente 70 cumplían los requisitos de la búsqueda. Todos los estudios consultados coinciden en la importancia de las hormonas gastrointestinales como principales agentes moduladores de la homeostasis energética. Dicho efecto modulador sobre el apetito y la saciedad tiene lugar mediante su acción directa sobre el hipotálamo o el núcleo del tracto solitario a nivel del tronco encefálico (sistema nervioso vegetativo). Únicamente la ghrelina, ha sido relacionada con el inicio de la ingesta considerándola una de las principales señales orexigénicas en los modelos animales estudiados y en humanos. Discusión: La regulación de la ingesta alimentaria y el balance energético constituye un proceso extremadamente complejo cuyo funcionamiento y equilibrio es posible gracias a la acción de las distintas señales endocrinas del tracto gastrointestinal. The regulation of energy intake is a vital process in the body as possible to maintain a balance between the amount of energy stored as body fat and the catabolism of the same. Objective: The objective of this study was to analyze the main factors involved in regulating food intake, energy balance and pathophysiology. Methods: We searched Medline and Ebsco of articles published in English and Spanish in the period between January 2009 and January 2012. Search terms were "food intake", "energy balance", "regulation", "nutritional homeostasis." Results: There were a total of 198 scientific studies, of which only 70 met the requirements of the search. All studies consulted agree on the importance of gastrointestinal hormones modulating agents as primary energy homeostasis. Such a modulatory effect on appetite and satiety is mediated by direct action on the hypothalamus or the nucleus of the solitary tract at the brainstem (autonomic nervous system). Only ghrelin has been linked to the start of the intake considering a major orexigenicas signals studied in animal models and humans. Discussion: The regulation of food intake and energy balance is an extremely complex process whose operation and balance is made possible by the action of various endocrine signals of the gastrointestinal tract.

Los objetivos de este estudio fueron determinar el estado nutricional de la población de escolares estudiada. En segundo lugar, analizar el patrón de distribución de la grasa subcutánea entre dicha población. La muestra estaba constituida por 977 escolares de Granada capital y provincia (524 chicas y 452 chicos), todos ellos con edades comprendidas entre los 9 y los 17 años. Para el estudio del estado nutricional y distribución del componente graso subcutáneo se realizó una evaluación antropométrica completa incluyendo una valoración del peso, estatura, índice de masa corporal, pliegues cutáneos y perímetros corporales. Los resultados obtenidos muestran la existencia de una prevalencia de sobrepeso del 23,01% en chicas frente a un 20,81% en chicos. Asimismo, se encontró una prevalencia de obesidad del 12,70% entre las chicas frente a un 4,98% en chicos. El análisis del patrón de distribución de la grasa subcutánea evidenció una distribución del componente graso de predominio eminentemente central. La existencia de una prevalencia importante de sobrepeso y obesidad unida al desarrollo de un patrón de distribución graso de predominio central, ponen de manifiesto el potencial riesgo cardiovascular al que se encuentran expuestos dichos alumnos. The objective of this study was to first determine the nutritional state of a sample population of school children, and then analyze the distribution pattern of their subcutaneous fat layer. The sample was composed of 977 school children from the city and province of Granada (Spain). All of the children (524 girls and 452 boys) were 9-17 years of age. To study their nutritional state and the distribution of the subcutaneous fat layer, they were given a complete anthropometric evaluation, which included measuring their weight, height, body mass index, skin folds, and body perimeters. The results obtained showed a 23.01% prevalence of overweight in the female subjects and 20.81% in the male subjects. Furthermore, the female subjects had an obesity prevalence of 12.70% in comparison to the male subjects, whose obesity prevalence was 4.98%. The distribution pattern of subcutaneous fat was found to be mainly located in the central part of body. The high percentage of overweight and obesity along with the development of a central fat distribution pattern (neck, chest, and abdomen) in these school children is clear evidence of potential cardiovascular risk.

Numerosos estudios han analizado la posible asociación entre el desarrollo de obesidad, niveles hormonales y su relación con el desarrollo precoz de cáncer de mama. Se llevó a cabo una recogida de datos retrospectiva a partir de las historias clínicas de 524 mujeres de Granada (España) diagnosticadas de cáncer de mama. Los objetivos fueron verificar una asociación entre el estado nutricional y la edad de diagnóstico, así como una posible relación entre el estado nutricional de las pacientes y los niveles séricos de estrógenos. Los resultados obtenidos en este estudio muestran que la obesidad y los niveles de ciertas hormonas como los estrógenos se encuentran íntimamente asociados con el desarrollo precoz del cáncer de mama. Many studies have analyzed the possible association between the development of obesity and hormone levels, as well as their relation with the early development of breast cancer. As part of this study, we performed a retrospective collection of data from the clinical histories of 524 women in Granada (Spain), who had been diagnosed with breast cancer. The objectives were to verify an association between the nutritional state of the women and their age at breast cancer diagnosis as well as a possible relation between their nutritional state and seric levels of estrogens. The results obtained in this study show that obesity and the levels of certain hormones, such as estrogens, are closely associated with the early development of breast cancer.

En la actualidad se acepta que la obesidad constituye un proceso eminentemente inflamatorio. Ello tiene su justificación en las alteraciones descritas en sujetos obesos a nivel de la secreción de ciertas citoquinas tales como ceruloplasmina, leptina, adiponectina e interleuquina 6 (IL-6), entre otras. Asimismo y en modo paralelo, otros trabajos apuntan además hacia alteraciones en la composición de ácidos grasos en la membrana de los eritrocitos de adultos obesos. Los resultados obtenidos en este estudio confirman la existencia de una correlación significativa entre los niveles séricos de algunas de las citokinas estudiadas y el estado nutricional de los sujetos, lo que significa que para la población de escolares valorada, las concentraciones séricas de estas biomoléculas pueden constituir una importante herramienta para predecir el riesgo cardiovascular en la edad adulta. Además, se han encontrado diferencias significativas respecto de la composición en ácidos grasos saturados en la membrana de los eritrocitos. There is a general consensus that obesity is an eminently inflammatory process. This is justified by alterations observed in obese patients, which affect the secretion of certain cytokines such as ceruloplasmin, leptin, adiponectin, and interleukin-6 (IL-6), among others. In a parallel way, other research has also pointed out alterations in the composition of fatty acids in the erythrocyte membrane of overweight adults. The results obtained in our study confirm the existence of a significant correlation between the serum levels of some of the cytokines studied and the nutritional state of the sample studied. This means that for the population of children evaluated in our study, the serum concentrations of these biomolecules can be an important tool for the prediction of cardiovascular risk when they become adults. Furthermore significant differences were found regarding the composition of saturated fatty acids in the erythrocyte membrane.

La OMS considera la obesidad como uno de los problemas de salud pública más importantes en el mundo, especialmente entre la población infantil y juvenil. Según esto, resulta prioritario mejorar y profundizar en el estudio de las diferentes metodologías de diagnóstico y valoración del estado nutricional en población pediátrica y adolescente. Actualmente, son utilizados como indicadores del estado nutricional el índice de masa corporal y el porcentaje de grasa corporal. Ahora bien, respecto del segundo, existe cierta controversia por considerar que tiende a sobreestimar el sobrepeso y la obesidad. Los objetivos a alcanzar con el desarrollo de este estudio fueron determinar la prevalencia de sobrepeso y obesidad en una población de escolares de entre 9 y 17 años de edad pertenecientes a 13 centros educativos de la ciudad de Granada y provincia. En segundo lugar, verificar posibles diferencias significativas a nivel de la precisión del índice de masa corporal y el porcentaje de grasa corporal para diagnosticar sobrepeso y obesidad. The World Health Organization (WHO) regards obesity as one of the most serious public health problems in the world that can affect young children and adolescents. Accordingly, a major priority is to find ways to more effectively study and analyze the various methods used to diagnose and evaluate the nutritional state of the pediatric and adolescent population. The nutritional indicators currently employed for this purpose are the body mass index and body-fat percentage. However, there is a certain controversy related to the body-fat percentage since it tends to overestimate overweight and obesity. The main objectives of this study were the following: (i) to determine the prevalence of overweight and obesity in a population of primary and secondary school children between 9-17 years of age at 13 educational centers in the city and province of Granada; (ii) to verify possible differences regarding the accuracy of the body mass index and the body-fat percentage in the diagnosis of overweight and obesity.

La muestra estaba constituida por 977 escolares de Granada capital y provincia (524 chicas y 452 chicos), todos ellos con edades comprendidas entre los 9 y los 17 años. Para el estudio del estado nutricional y distribución del componente graso subcutáneo se realizó una evaluación antropométrica completa incluyendo una valoración del peso, estatura, índice de masa corporal, pliegues cutáneos y perímetros corporales. Los resultados obtenidos muestran la existencia de una prevalencia de sobrepeso del 23,01% en chicas frente a un 20,81% en chicos. Asimismo, se encontró una prevalencia de obesidad del 12,70% entre las chicas frente a un 4,98% en chicos. El análisis del patrón de distribución de la grasa subcutánea evidenció una distribución del componente graso de predominio eminentemente central. La existencia de una prevalencia importante de sobrepeso y obesidad unida al desarrollo de un patrón de distribución graso de predominio central, ponen de manifiesto el potencial riesgo cardiovascular al que se encuentran expuestos dichos alumnos.

4 páginas, 2 tablas., [EN]There is a general consensus that obesity is an eminently inflammatory process. This is justified by alterations observed in obese patients, which affect the secretion of certain cytokines such as ceruloplasmin, leptin, adiponectin, and interleukin-6 (IL-6), among others. In a parallel way, other research has also pointed out alterations in the composition of fatty acids in the erythrocyte membrane of overweight adults. The results obtained in our study confirm the existence of a significant correlation between the serum levels of some of the cytokines studied and the nutritional state of the sample studied. This means that for the population of children evaluated in our study, the serum concentrations of these biomolecules can be an important tool for the prediction of cardiovascular risk when they become adults. Furthermore significant differences were found regarding the composition of saturated fatty acids in the erythrocyte membrane., [ES] En la actualidad se acepta que la obesidad constituye un proceso eminentemente inflamatorio. Ello tiene su justificación en las alteraciones descritas en sujetos obesos a nivel de la secreción de ciertas citoquinas tales como ceruloplasmina, leptina, adiponectina e interleuquina 6 (IL-6), entre otras.

Estudios recientes muestran un incremento alarmante en las tasas de sobrepeso y obesidad entre la población infantil y juvenil. Los objetivos de este trabajo fueron realizar una valoración del estado nutricional y composición corporal mediante antropometría en una población de escolares de Granada capital y provincia, así como comparar el estado nutricional de la población escolar estudiada con los estándares nacionales e internacionales de referencia. La prevalencia general de sobrepeso encontrado en ambos sexos fue del 22,03% y la tasa de obesidad del 9,12%. Se encontraron diferencias estadísticamente significativas entre la variable peso para la edad y el sexo (p < 0,05) y la variable estatura para la edad y sexo (p < 0,05). Respecto del índice de masa corporal, no se encontraron diferencias estadísticamente significativas para la variable sexo (p = 0,182) pero sí respecto de la variable edad (p < 0,05). Por último, cabe resaltar como los valores de antropometría estimados, se sitúan muy por encima de los estándares de referencia tanto nacionales como internacionales. Recent studies show an alarming increase in levels of overweight and obesity among children and adolescents. The main objectives of this research were the following: (i) to carry out an anthropometric evaluation of the nutritional status and body composition of school children in the city and province of Granada; (ii) to compare the nutritional status of this population sample with national and international reference standards. The results obtained in this study showed that the general prevalence of overweight in both sexes was 22.03% and that 9.12% of the children were obese. Statistically significant differences were found between the variable, weight for age and sex (p < 0.05) and the variable, height for age and sex (p < 0.05). Regarding the body mass index, no statistically significant differences were found for the variable, sex (p = 0.182). This contrasted with the variable, age, which did show statistically significant differences (p < 0.05). As a conclusion, the results of our study highlighted the fact that these anthropometric values were much higher than national and international reference standards.

La literatura científica existente plantea la necesidad de entender la conducta alimentaria como un proceso cíclico e interactivo, según el cual los hábitos y la conducta alimentaria de los padres llevan a sus hijos a desarrollar estrategias especificas de alimentación, esto es, a la definición de conductas alimentarias propias, lo que tendrá su reflejo en los indicadores nutricionales del niño. Los objetivos de este estudio han sido verificar la existencia de una asociación significativa entre el nivel educativo de los padres y el estado nutricional de sus hijos, comprobar si existe una relación directa entre el estado nutricional de los hijos y quién es la persona que elabora el menú familiar y determinar el posible vínculo entre el estado nutricional de los hijos y el tiempo que éstos dedican a la práctica del ocio sedentario. La población de estudio estuvo constituida por 718 niños y adolescentes escolares de entre 9 y 17 años de edad, pertenecientes todos ellos a trece centros educativos públicos y privados de la ciudad de Granada y de su provincia. Se trata de un estudio descriptivo, transversal y multicéntrico en el que se llevó a cabo una valoración del estado nutricional de toda la población de alumnos correspondientes a trece centros educativos. Mediante el uso de técnicas de antropometría se valoraron las variables peso, talla y, con ello, el índice de masa corporal., According to recent research, eating behaviour should be understand as a cyclical and interactive process in which parental eating habits cause children to develop specific eating strategies as well as their own eating habits. Needless to say, this interactive process is reflected and has a direct impact on the nutritional indicators of the children in a family. The objectives of this study were the following: (i) to verify the existence of a significant association between the educational level of parents and the nutritional state of children in the same family; (ii) to discover if there is a direct relation between the nutritional state of children and the person that decides the menu and/or prepares family meals; (iii) to determine if there is a link between the nutritional state of children and the time that they spend on sedentary leisure activities. The sample population was composed of 718 school children and adolescents, 9-17 years of age, who A descriptive, transversal, and multicentric study was performed that evaluated the nutritional state of the entire sample by using anthropometric techniques to assess weight, height, and body mass index.

Sobrepeso ,Obesidad ,Motivación ,Adolescente - Abstract
España se ha convertido en el cuarto país de la Unión Europea con mayor número de niños con sobrepeso y obesidad. Esta enfermedad afecta directamente tanto aspectos de salud físicos como psicológicos. El objetivo es evaluar el grado de motivación existente en dos grupos de adolescentes, uno cuyos sujetos se encuentran en normo-peso y un segundo grupo integrado por adolescentes con sobrepeso u obesidad. Se realizó un estudio observacional, descriptivo en un centro educativo de Guadix (Granada). El universo estuvo constituido por 200 niños con edades comprendidas entre los 10 y 14 años, de los que fueron seleccionados una muestra de 24 niños mediante el muestreo Aleatorio Simple de Proporciones con error de 0.19 distribuidos en: Grupo de niños normopeso: 12 y Grupo de niños obesos: 12. Para medir la motivación se utilizó el Test de Motivaciones en Adolescentes (SMAT) que pertenece a los instrumentos de medida derivados del modelo dinámico cattelliano. Evaluó cinco parámetros relacionados con la motivación: TAO (total autismo-optimismo), TIG (total información general), TIN (total integración), TIP (total interés personal) y TCO (total conflicto). De entre los resultados obtenidos, cabe destacar como en cada una de las variables del SMAT los niños incluidos en el grupo de sobrepeso y obesidad mostraron un resultado promedio de (4,5) con respecto a un resultado promedio en los niños normopesos de (5,9) lo que pone de manifiesto que los sujetos que padecen sobrepeso y obesidad presentan un nivel de motivación más bajo, circunstancia que se manifiesta por una mayor tendencia hacia la frustración y mayores dificultades para alcanzar sus metas.

Introducción: Diversos autores han encontrado correlaciones entre parámetros antropométricos y los niveles de presión arterial en sujetos con sobrepeso y obesidad. El presente trabajo supone una puesta al día sobre las potencialidades de dichos parámetros como un instrumento más de predicción del riesgo cardiovascular. Objetivos: Realizar una estimación de la prevalencia de sobrepeso y obesidad. En segundo lugar verificar la existencia de una correlación significativa entre los principales indicadores antropométricos valorados y los niveles de presión arterial mostrados por los alumnos. Muestra: una población constituida por 977 niños y adolescentes de entre 9 y 17 años de edad pertenecientes a 13 centros educativos de la provincia de Granada y ciudad. Metodología: Se realizó una evaluación antropométrica en la que fueron valorados seis pliegues cutáneos, la circunferencia de la cintura, de la cadera y la determinación de la presión arterial en hasta tres ocasiones consecutivas. Esta fase de valoración antropométrica comenzó en marzo de 2008 prolongándose hasta mayo de 2009. Resultados: Se encontró una prevalencia de sobrepeso en chicas que oscilaba entre el 18,3% y el 32,2%. Por su parte, entre los chicos su prevalencia se situaba entre el 10,9% y el 26,1%. Respecto de la prevalencia de obesidad, las chicas mostraron tasas comprendidas entre el 4,5% y el 15,1%. Entre los chicos la prevalencia de obesidad resultó similar, encontrando tasas comprendidas entre el 4,7% y el 12,6%. De todos los parámetros valorados, el índice de masa corporal y la circunferencia fueron los indicadores antropométricos que mayor grado de correlación mostraron respecto de las cifras de presión arterial. Conclusiones: El índice de masa corporal, así como la circunferencia de la cintura constituyen indicadores antropométricos precisos para predecir el riesgo cardiovascular en sujetos no adultos. Introduction: Several authors have found correlations between anthropometric parameters and blood pressure levels in overweight and obese subjects. This paper is an update on the potential of these parameters as a tool for predicting cardiovascular risk. Aims: to estimate the prevalence of overweight and obesity. Second verify the existence of a significant correlation between the main anthropometric indicators and the blood pressure levels. Sample: The population consisted of 977 children and adolescents between 9 and 17 years of age belonging to 13 schools in the province of Granada and city. Methodology: anthropometric evaluation in which they were assessed six skinfolds, waist circumference, hip and determination of blood pressure in three consecutive occasions. The anthropometric assessment phase began in March 2008 lasted until April 2009. Results: We found that the prevalence of overweight in girls varied between 18.3% and 32.2%. For its part, the prevalence among boys was between 10.9% and 26.1%. Regarding the prevalence of obesity, the girls had similar rates between 4.5% and 15.1%. Among boys the prevalence of obesity was similar, and found rates between 4.7% and 12.6%. Of all the parameters measured, body mass index and waist circumference were the anthropometric indicators that showed a better correlation to blood pressure. Conclusions: BMI and WC are useful anthropometric indicators to predict cardiovascular risk in non adults.

Objetivos: El objeto del presente trabajo es estudiar la prevalencia de la obesidad y el sobrepeso en una población de escolares y verificar la efectividad de la intervención educativa desarrollada sobre esos alumnos en términos de mejora de los valores percentilados del índice de masa corporal. Material: La población valorada está compuesta por 977 escolares de entre 9 y 17 años de edad, pertenecientes a 13 centros educativos públicos de la ciudad de Granada y de su provincia (España). Metodología: Se trata de un estudio longitudinal, analítico, multicéntrico y observacional de cohortes, desarrollado en tres fases. En primer lugar, valoración del estado nutricional, mediante técnicas antropométricas (peso, talla e índice de masa corporal, seis pliegues cutáneos y cuatro perímetros corporales) así como la presión arterial. Una segunda fase en la que se desarrolló la intervención educativa sobre la alimentación y el ejercicio físico. En la fase final se evaluó la efectividad de la intervención. Resultados: Se encontró una mayor prevalencia de obesidad en las chicas de entre 12 y 13 años (15,1%). En los chicos, la prevalencia de obesidad fue inferior hasta los 13 años, aunque después mostraron un creciente incremento de dicha prevalencia (12,6%). Se produjo una reducción significativa de los valores de IMC en los dos sexos, aunque más significativa entre las chicas. Conclusiones: Existe un incremento alarmante en la prevalencia de sobrepeso y obesidad entre la población valorada. La reducción significativa de las puntuaciones en el IMC confirma la efectividad de la intervención educativa desarrollada. Objectives: The objective of this research was to study the prevalence of obesity and excess weight in a population of school children and adolescents, and to verify the effectiveness of an educational intervention, as reflected in the variation of their body mass index values. Materials: The population sample was composed of 977 school children and adolescents from 9 to 17 years of age, belonging to 13 public elementary schools and high schools in the city and province of Granada (Spain). Methodology: This longitudinal cohort study was analytical, muticentric, and observational. It was carried out in three phases. The first phase involved the evaluation of the nutritional state of the sample population by means of anthropometric measurements (weight, height, body mass index, six skin folds and four body perimeters) as well as arterial blood pressure. The second phase entailed an educational intervention focusing on good nutritional habits and physical exercise. The third and final phase evaluated the effectiveness of the intervention. Results: A higher obesity prevalence (15.1%) was found in school girls between 12 and 13. In the case of boys, obesity prevalence was lower up to age 13 though afterwards, it progressively increased (12.6%). The educational intervention produced an important reduction in body mass index values in both sexes though this reduction was more significant in young females. Conclusions: There is a currently an alarming increase in obesity and overweight prevalence among the population evaluated in this study. The significant reduction in body mass index values resulting from this research confirmed the effectiveness of the educational intervention to reduce excess weight.

Resultado de ello y para la población de adolescentes con sobrepeso y obesidad estudiada, la valoración de las concentraciones séricas de estas biomoléculas resultó ser un importante instrumento para identificar aquellos sujetos con un riesgo elevado de padecer trastornos cardiovasculares, fundamentalmente derivados de un estatus hipertensivo., [EN] Numerous studies have focused on establishing a relation between the serum values of biomolecules such as leptin, ceruloplasmin, and lipoprotein (a), and the nutritional state and levels of diastolic and systolic blood pressure in subjects with problems of overweight or obesity. However, in many cases, the results obtained have not been conclusive. The results of our study confirm the existence of a statistically significant association between the serum levels of these biomolecules, the nutritional state of the subjects, and levels of diastolic and systolic blood pressure. For the population of overweight and obese adolescents studied, the evaluation of the serum concentrations of these biomolecules was found to be an important instrument that could be used to identify those subjects with an elevated risk of suffering cardiovascular disorders basically derived from a hypertensive status.

El exceso de peso corporal de la población ha llevado a la Organización Mundial de la Salud a calificarlo como epidemia global. La prevalencia de sobrepeso y obesidad infantil en España se sitúa entre las más elevadas del continente europeo, y es aún superior en Andalucía. Las consecuencias para la salud de los niños no son tan evidentes como en los adultos, pero la obesidad infantil se está asociando con patologías que se creían eran sólo padecidas por los adultos, tales como el síndrome metabólico. La resistencia a la insulina es el factor de riesgo más importante en sujetos con obesidad severa, que junto con la obesidad visceral, exacerban la trigliceridemia postprandial, lo que incrementa el riesgo cardiovascular. Sin embargo y a nuestro entender, este fenómeno no ha sido debidamente estudiado por el momento en la población infantil. Las propiedades cardiosaludables del aceite de oliva, el ingrediente principal de la Dieta Mediterránea, han sido sobradamente puestas de manifiesto, que incluyen un mejor patrón lipídico postprandial. En este contexto, el objetivo de este estudio es determinar los efectos de un desayuno de tipo mediterráneo sobre parámetros lipídicos postprandiales en preadolescentes con sobrepeso y obesidad. Para ello, se ha llevado a cabo un estudio cuasi experimental prospectivo multicéntrico, que compara los beneficios de una intervención dietética en una sola comida de tipo mediterráneo en el metabolismo lipídico postprandial en sujetos en edades preadolescentes (10-14 años) afectados por obesidad o sobrepeso (grupo estudio), con respecto a los sujetos normopeso (grupo control). Los resultados permiten ampliar el conocimiento sobre la fisiopatología de la obesidad de los niños y contribuir a las recomendaciones dietéticas para el mantenimiento de la población infantil. Más aún, aportan información sobre el desarrollo de aterogénesis durante el periodo postprandial, que puede comenzar a edades tan tempranas. The excess weight that characterizes much of the population of the world today has led the World Health Organization to declare a obesity pandemic. The number of overweight and obese children in Spain is among the highest in Europe, and this number is even higher in Andalusia. The health consequences of excess weight for children are not as evident as for adults. However, child obesity is now being associated with pathologies, such as the metabolic syndrome, which were previously believed to be only found in adults. Resistance to insulin is an important risk factor in subjects with severe obesity, which along with visceral obesity, make postprandial triglyceridemia more severe. This increases cardiovascular risk. However, in our opinion, this phenomenon has not been adequately studied in children. The hearthealthy properties of olive oil, the main ingredient of the Mediterranean diet, have been clearly highlighted in various studies. These properties include an improved postprandial lipid pattern. In this context, the objective of this study was to determine the effects of a Mediterranean-diet breakfast on the postprandial lipid parameters in a study group of overweight and obese preadolescents (age 10-14) in comparison to a control group of subjects with no weight problems. The results obtained provide greater knowledge of the physiopathology of child obesity and contribute to the elaboration of dietary recommendations for the maintenance of child health. Additionally, our results give information regarding the development of atherogenesis during the postprandial period, which can begin at a very early age.

Las consecuencias para la salud de los niños no son tan evidentes como en los adultos, pero la obesidad infantil se está asociando con patologías que se creían eran sólo padecidas por los adultos, tales como el síndrome metabólico. La resistencia a la insulina es el factor de riesgo más importante en sujetos con obesidad severa, que junto con la obesidad visceral, exacerban la trigliceridemia postprandial, lo que incrementa el riesgo cardiovascular. Sin embargo y a nuestro entender, este fenómeno no ha sido debidamente estudiado por el momento en la población infantil. Las propiedades cardiosaludables del aceite de oliva, el ingrediente principal de la Dieta Mediterránea, han sido sobradamente puestas de manifiesto, que incluyen un mejor patrón lipídico postprandial. En este contexto, el objetivo de este estudio es determinar los efectos de un desayuno de tipo mediterráneo sobre parámetros lipídicos postprandiales en preadolescentes con sobrepeso y obesidad. Para ello, se ha llevado a cabo un estudio cuasi experimental prospectivo multicéntrico, que compara los beneficios de una intervención dietética en una sola comida de tipo mediterráneo en el metabolismo lipídico postprandial en sujetos en edades preadolescentes (10-14 años) afectados por obesidad o sobrepeso (grupo estudio), con respecto a los sujetos normopeso (grupo control). Los resultados permiten ampliar el conocimiento sobre la fisiopatología de la obesidad de los niños y contribuir a las recomendaciones dietéticas para el mantenimiento de la población infantil. Más aún, aportan información sobre el desarrollo de aterogénesis durante el periodo postprandial, que puede comenzar a edades tan tempranas., [EN] The excess weight that characterizes much of the population of the world today has led the World Health Organization to declare a obesity pandemic.

Introducción: El cáncer de mama constituye el tumor ginecológico más frecuente entre las mujeres jóvenes de los países occidentales. Sus graves consecuencias para la salud y una cada vez más temprana edad de diagnóstico han llevado a analizar cuidadosamente sus causas y posibles medidas preventivas, convirtiéndose su estudio en un objetivo primario de la investigación epidemiológica. Muestra y métodos: se revisaron 504 historias clínicas pertenecientes a pacientes de sexo femenino con edades comprendidas entre los 19 y los 91 años. Todos ellas diagnosticadas y tratadas de cáncer de mama entre los años 2003 a 2008 en el Hospital Universitario "San Cecilio" de Granada (España). Resultados: se encontró una correlación significativa (p = 0,001) entre la edad de diagnóstico del cáncer, el tiempo de lactancia materna, y la existencia de antecedentes familiares y personales para cáncer. Por el contrario, no se encontraron diferencias estadísticamente significativas test (t-Student) entre la edad media de diagnóstico del cáncer y el hecho de haber tenido o no descendencia (t = 0,559, p = 0,576). Conclusiones: la lactancia materna por períodos de tiempo superiores a seis meses, no sólo proporciona a los niños numerosos beneficios para su salud, sino que también puede proteger a la madre de enfermedades graves, como lo es el cáncer de mama.

- Abstract
Unhealthy dietary habits are key determinants of obesity in adolescents. Assuming that dietary fat profile influences membrane lipid composition, the aim of this study was to analyze structural changes in the erythrocyte membrane of obese compared to normal-weight adolescents. The study was conducted in a group of 11 obese and 11 normal-weight adolescent subjects. The lipid profile, lipid peroxidation and acetylcholinesterase enzyme (AChE) activity were analyzed by conventional methods. The structural properties of reconstituted erythrocyte membrane were characterized by X-ray diffraction. Erythrocyte membrane from obese adolescents had a lipid profile characterized by a higher cholesterol/phospholipid ratio, an increase in saturated fatty acid and a decrease in monounsaturated and n-6 polyunsaturated fatty acid concentrations. Differences in lipid content were associated with changes in the structural properties of reconstituted membranes and the oxidative damage of erythrocyte membrane. The lower oxidative level shown in the obese group (0.15 ± 0.04 vs. 0.20 ± 0.06 nmol/mg for conjugated diene concentrations and 2.43 ± 0.25 vs. 2.83 ± 0.31 nmol/mg protein for malondialdehyde levels) was related to a lower unsaturation index. These changes in membrane structural properties were accompanied by a lower AChE activity (1.64 ± 0.13 vs. 1.91 ± 0.24 nmol AChE/[min mg protein]) in the obese group. The consequences of unhealthy dietary habits in adolescents are reflected in the membrane structural properties and may influence membrane-associated protein activities and functions.

- Abstract
AIMS AND OBJECTIVES: To ascertain whether inflammation markers also correlate with parameters related to insulin resistance and the metabolic syndrome in a group of adolescents. BACKGROUND: Obesity is now considered a chronic low-grade inflammatory process, characterised by alterations in the systemic concentrations of some inflammation markers. Adiponectin, leptin and other inflammatory proteins have been shown to correlate with insulin resistance and the metabolic syndrome in adults. DESIGN: Cross-sectional study in two groups of obese and normal weight adolescents. METHODS: Serum levels of adiponectin, leptin, ceruloplasmin and insulin levels were determined and correlated among them and with anthropometric parameters, blood pressure body mass index and body mass index z-score. RESULTS: Waist circumference, body mass index and blood pressure values correlated significantly with both homoeostasis model assessment for insulin resistance and insulin levels. Ceruloplasmin also correlated with both parameters with a high level of significance. However, leptin levels did not correlate with either homoeostasis model assessment for insulin resistance or insulin, and adiponectin correlated with homoeostasis model assessment for insulin resistance but not insulin. All inflammation markers studied correlated with the body mass index z-score. These correlations were stronger in the group of obese individuals compared to lean ones. CONCLUSIONS: We found a relationship between insulin resistance and some inflammation in adolescents, which was particularly strong in obese individuals and was associated with the development of metabolic syndrome. Among the inflammation markers studied, ceruloplasmin revealed as a potential string marker of insulin resistance in obese adolescents. RELEVANCE TO CLINICAL PRACTICE: The results obtained in this study imply a significant advance in the field of clinical practice of nursing.

- Abstract
According to recent research, eating behaviour should be understand as a cyclical and interactive process in which parental eating habits cause children to develop specific eating strategies as well as their own eating habits. Needless to say, this interactive process is reflected and has a direct impact on the nutritional indicators of the children in a family. The objectives of this study were the following: (i) to verify the existence of a significant association between the educational level of parents and the nutritional state of children in the same family; (ii) to discover if there is a direct relation between the nutritional state of children and the person that decides the menu and/or prepares family meals; (iii) to determine if there is a link between the nutritional state of children and the time that they spend on sedentary leisure activities. The sample population was composed of 718 school children and adolescents, 9-17 years of age, who A descriptive, transversal, and multicentric study was performed that evaluated the nutritional state of the entire sample by using anthropometric techniques to assess weight, height, and body mass index.

- Abstract
Objectives: The objective of this research was to study the prevalence of obesity and excess weight in a population of school children and adolescents, and to verify the effectiveness of an educational intervention, as reflected in the variation of their body mass index values.Materials: The population sample was composed of 977 school children and adolescents from 9 to 17 years of age, belonging to 13 public elementary schools and high schools in the city and province of Granada (Spain).Methodology: This longitudinal cohort study was analytical, muticentric, and observational. It was carried out in three phases. The first phase involved the evaluation of the nutritional state of the sample population by means of anthropometric measurements (weight, height, body mass index, six skin folds and four body perimeters) as well as arterial blood pressure. The second phase entailed an educational intervention focusing on good nutritional habits and physical exercise. The third and final phase evaluated the effectiveness of the intervention.Results: A higher obesity prevalence (15.1%) was found in school girls between 12 and 13. In the case of boys, obesity prevalence was lower up to age 13 though afterwards, it progressively increased (12.6%). The educational intervention produced an important reduction in body mass index values in both sexes though this reduction was more significant in young females.Conclusions: There is a currently an alarming increase in obesity and overweight prevalence among the population evaluated in this study. The significant reduction in body mass index values resulting from this research confirmed the effectiveness of the educational intervention to reduce excess weight. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background: In Spain the prevalence of obesity shows a north-south distribution. In the province of Granada its distribution is unknown. Objectives: (1) To study the prevalence of overweight and obesity in a sample population of school children and adolescents from different districts in the province of Granada. (2) To verify whether there are significant differences, depending on the district where the students reside. (3) To find a possible correlation between the nutritional state of the students and that of their parents. Methods: The population sample was composed of 977 school children and adolescents from 9 to 17 years of age, attending 13 public elementary schools and high schools in the city and province of Granada (Spain). In this analytical and multicentric study, the nutritional state of the subjects was evaluated by means of anthropometric measurements. Furthermore, data were collected by means of questionnaire to discover whether the respondents had a family history of overweight or obesity. Results: We found a high prevalence of overweight and obesity among the studied population. In girls, the greater prevalence of both overweight and obesity ranged from 12 to 14 years of age. In boys, there was an increase in the prevalence of overweight at twelve years of age. Regarding obesity, their rates were significantly lower than those described among girls. There were statistically significant differences for weight (F = 4,154; p = 0,003) but not for height (F = 1,928; p =0,105). But for the variable BMI was statistically significant difference (F = 5.037; P < 0.001) between the studied geographical areas. The results showed that the nutritional state of students with a family history of obesity was significantly worse (p < 0.01). Discussion: A high prevalence of obesity was found in the sample, especially among the girls. There exists a geographical distribution pattern, possibly derived from the socioeconomic characteristics of each area in the province. The existence of a family history of obesity is an important factor that can determine whether the child will also become obese in the future. [ABSTRACT FROM AUTHOR]

- Abstract
The regulation of energy intake is a vital process in the body as possible to maintain a balance between the amount of energy stored as body fat and the catabolism of the same. Objective: The objective of this study was to analyze the main factors involved in regulating food intake, energy balance and pathophysiology. Methods: We searched Medline and Ebsco of articles published in English and Spanish in the period between January 2009 and January 2012. Search terms were 'food intake', 'energy balance', 'regulation', 'nutritional homeostasis.' Results: There were a total of 198 scientific studies, of which only 70 met the requirements of the search. All studies consulted agree on the importance of gastrointestinal hormones modulating agents as primary energy homeostasis. Such a modulatory effect on appetite and satiety is mediated by direct action on the hypothalamus or the nucleus of the solitary tract at the brainstem (autonomic nervous system). Only ghrelin has been linked to the start of the intake considering a major orexigenicas signals studied in animal models and humans. Discussion: The regulation of food intake and energy balance is an extremely complex process whose operation and balance is made possible by the action of various endocrine signals of the gastrointestinal tract.

- Abstract
The objective of this study was to first determine the nutritional state of a sample population of school children, and then analyze the distribution pattern of their subcutaneous fat layer. The sample was composed of 977 school children from the city and province of Granada (Spain). All of the children (524 girls and 452 boys) were 9-17 years of age. To study their nutritional state and the distribution of the subcutaneous fat layer, they were given a complete anthropometric evaluation, which included measuring their weight, height, body mass index, skin folds, and body perimeters. The results obtained showed a 23.01% prevalence of overweight in the female subjects and 20.81% in the male subjects. Furthermore, the female subjects had an obesity prevalence of 12.70% in comparison to the male subjects, whose obesity prevalence was 4.98%. The distribution pattern of subcutaneous fat was found to be mainly located in the central part of body. The high percentage of overweight and obesity along with the development of a central fat distribution pattern (neck, chest, and abdomen) in these school children is clear evidence of potential cardiovascular risk.

- Abstract
Many studies have analyzed the possible association between the development of obesity and hormone levels, as well as their relation with the early development of breast cancer. As part of this study, we performed a retrospective collection of data from the clinical histories of 524 women in Granada (Spain), who had been diagnosed with breast cancer. The objectives were to verify an association between the nutritional state of the women and their age at breast cancer diagnosis as well as a possible relation between their nutritional state and seric levels of estrogens. The results obtained in this study show that obesity and the levels of certain hormones, such as estrogens, are closely associated with the early development of breast cancer. [ABSTRACT FROM AUTHOR]

- Abstract
Spain has become the country in the European Union with the fourth highest number of overweight and obese children. This condition directly affects physical health as well as mental health. The objective of this research study was to evaluate motivational aspects in one group of obese or overweight adolescents and another group of normal-weight adolescents. For this purpose a descriptive observational study was carried out in an educational institution in Guadix (Granada). The universe was composed of 200 children of ages 10 to 14. A sample of 24 children was selected by means of proportional random sampling with an error of 0.19, and was divided into the following groups (i) 12 normal-weight children; (ii) 12 obese children. Motivation was measured by means of the School Motivation Analysis Test (SMAT), a multidimensional measuring instrument based on Cattell's dynamic model of motivation and emotions. Our study evaluated five motivational parameters: TAO (total autism-optimism), TGI (total general information), TIN (total integration), TPI (total personal interest), and TCO (total conflict). Our results showed that for each of the SMAT variables, the overweight and obese children obtained an average value of 4.5 in contrast to the normal-weight children, who obtained an average value of 5.9. This indicates that overweight and obese children have low motivational states and a higher level of frustration. They also tend to distort reality by alleging the existence of obstacles that prevent them from achieving their goals. [ABSTRACT FROM AUTHOR]
