RESUMO
The purpose of this cross-cultural study was to determine the association between the sociodemographic background of a child's parents (i.e., their socioeconomic level, marital status, and educational level) with the child's lifestyle (i.e., Mediterranean diet (MD), physical activity (PA) and screen time (ST)), and health markers. Material: This cross-sectional study included 1273 children, from Chile (n = 496), Colombia (n = 340), and Spain (n = 437). The sociodemographic information together with the lifestyle and health markers of the children were measured. There was an inverse association between a low or medium-low socioeconomic level for the parents of Chilean children and handgrip strength (ß -0.61, p < 0.001); meanwhile, for Spanish children, an inverse association between a low or medium-low socioeconomic level and PA after school (ß -0.58, p = 0.016), lifestyle (ß -0.74, p = 0.015), and with MD adherence (ß -0.86, p = 0.004) was found. The risk (i.e., by odd ratios (OR)) of being divorced/separated parents marital status showed an inverse association with abdominal obesity (OR 0.21, p = 0.045) in Spanish children; however, the parent's marital status and a low educational level were risk factors for the suffering of a low nutritional level in Colombian children (OR 2.02, p = 0.048; OR 2.49, p < 0.001, respectively). On the other hand, a low educational level for parents reported for Chilean children had a positive association with ST of ≥4 h per day (OR 1.82, p = 0.020). In conclusion, in Spanish-speaking children, the lifestyle and health markers of the children are affected by the sociodemographic background of their parents; however, these effects could be moderated by the socio-cultural and economic status of their countries as members of the OCDE; therefore, it is essential to develop policies that decrease these gaps, so that children who are under-resourced can reach their full potential.

Professional practice is a relevant process for the personal and academic development of students. It uses learning contexts located in real scenarios and enables the acquisition of knowledge, skills, and competencies necessary for professional practice. Objective. To design and validate an instrument designed to evaluate students' satisfaction with theirprofessional practice process. Materials and methods. Mixed-method study, non-probabilistic sample by convenience of 196 participants. The sample is formed by 20 Nutritionists and 176 students belonging to the Nutrition and Dietetics undergraduate program. The statistical software SPSS version 22 was used to analyze reliability by Cronbach's alpha and the Delphi method for content validity. An instrument with 32 items grouped in 4 dimensions was elaborated and applied to 116 students to analyze reliability. The instrument was adjusted to 25 items, and content validity was analyzed by a panel of experts. The judge'sconsensus was the foundation for developing a 29-item version grouped into 4 dimensions. This version was applied to 60 students to obtainCronbach's alpha validation. Results. The instrument presents an excellent level of reliability, with a Cronbach's Alpha coefficient of 0.927. Conclusions. The instrument designed to measure satisfaction with professional practices is a reliable and valid measure, since it allows knowing the students 'evaluation at the end of their professional practice process(AU)

Antecedentes. En los últimos años se ha evidenciado la importancia de investigar sobre la obesidad, incluyendo a grupos de sujetos que presentan necesidades educativas especiales permanentes, como es el caso del Síndrome de Down. Objetivo. Determinar la correlación entre el Índice de Masa Corporal (IMC) con la circunferencia de cintura (CCi) y el IMC con la circunferencia de cadera (CCa) de los niños y adolescentes con síndrome de Down. Materiales y métodos. Se realizó un estudio de corte transversal, donde se evaluaron 42 niños y adolescentes, 23 hombres (54,7%) y 19 mujeres (35,3%), entre 3 y 16 años de edad, alumnos de escuelas especiales de Temuco, Chile. Para obtener el IMC y la CCa se utilizó el método descrito por la OMS. Resultados. Se evidencia un alto grado de correlación entre IMC y CCi (0,776) y entre IMC y CCa (0,771). Además el 61,9% del total presentan sobrepeso u obesidad. El 52,1% de los hombres y el 73,6% de las mujeres presentan obesidad o sobrepeso. Discusión. A partir de los resultados, es recomendable la utilización de la circunferencia de cintura y cadera, además del IMC para la detección temprana de problemas asociados a la obesidad. Además de focalizar el trabajo a realizar con esta población especial, generando estrategias que involucren a distintos profesionales del ámbito de la salud y del ejercicio físico, permitiendo abordar sistémicamente desde los primeros años la prevención de la obesidad y las patologías asociadas.
Background. The importance of investigating obesity has grown during recent years, especially regarding groups of people involving long-term special education needs, such as Down's syndrome. Objective. Determining the correlation between body mass index (BMI) and waist circumference and BMI and hip circumference in children and teenagers suffering Down's syndrome. Materials and methods. This cross-sectional study involved evaluating 42 children and adolescents aged 3 to 16 years old; 23 of them were male (54.7%) and 19 female (35.3%) and all were studying in specialised schools in Temuco, Chile. The method described by the WHO was used for obtaining BMI, waist and hip circumference measurements. Results. A high correlation was seen for both BMI and waist circumference (0.776) and BMI and hip circumference (0.771). It was also seen that 61.9% of the population studied were overweight or obese; 52.1% of the males and 73.6% of the females were either obese or overweight. Discussion. It is thus recommended that waist and hip circumference and BMI should be used for the early detection of obesity-related problems. Efforts should be specifically focused on this special population of people, leading to strategies involving healthcare workers in different areas as well as physical exercise. This would lead to the systematic prevention of obesity and associated pathologies from an early age.
RESUMO
El objetivo del estudio es determinar si el entrenamiento de fuerza de tipo intermitente modifica la composición corporal principalmente el porcentaje de grasa y masa muscular de jóvenes sedentarios universitarios. Estudio cuasi experimental con pre prueba y pos-prueba en una muestra de 8 sujetos sin grupo control, seleccionados de manera intencionada. Se realizó medición antropométrica al comienzo y al finalizar el programa de entrenamiento. Se concluyó que un programa de entrenamiento de 2 meses de duración con 3 sesiones semanales en días alternos, provoca disminución significativa (p<0,05) en la masa grasa y un aumento significativo (p<0,05) en la masa muscular, por lo cual se comprueba que el entrenamiento intermitente con sobrecarga, provoca cambios significativos en la fuerza máxima, y composición corporal en personas sedentarias.
The aim of the study is to determine whether strength training intermittent type body composition changes mainly fat percentage and muscle mass of young university sedentary. Quasi experimental study with pre-test and post-test on a sample of 8 subjects with no control group, selected intentionally. Anthropometric at the beginning and end of the training program was conducted measurement. It was concluded that a training program 2 months with 3 sessions per week on alternate days caused significant decrease (p <0.05) in fat mass and a significant increase (p <0.05) in muscle mass, which is proven by the intermittent resistance training causes significant changes in maximal strength, and body composition in sedentary people.
