Patrones de actividad física en niños con sobrepeso y normopeso: un estudio de validez concurrente

Childhood overweight and obesity and low levels of physical activity are highly prevalent and have negative effects on health. The aim of this study was to evaluate and compare physical activity patterns in overweight and obese children through objective (accelerometer) and subjective (the International Physical Activity Questionnaire [IPAQ]) measures and to evaluate the degree of concordance between these two measures. This study was carried out in 11 to 13-year-old children in five primary schools in south Navarre (Spain). Caltrac accelerometers and the self-administered IPAQ were used to measure physical activity levels. The results showed a lack of concordance between the measures used (r = 0.49; p < 0.001).

Análisis del trabajo no presencial utilizando un enfoque ETCS

Credit ECTS (European Credit Transfer and Accumulation System) is based on hours of dedication that students must assume to obtain the aims of a program. This research goal was to check importance of student’s homework in their first year in Physical Activity and Sport Sciences at Universidad Europea de Madrid to try to look for the right balance student’s weekly homework. Our specific goals are, in one side; generate activities considered homework, including measured average time of dedication for the student. On the other side, to classify activities to be considered homework from different points of view, to have a global vision of qualification acquired the students through their independently accepted activities.

Disordered Eating Issues in Active Children and Adolescence

The development of a child’s body image is strongly influenced by peers, school, family, society, and the media. While it is important for children to learn healthy eating habits and attitudes toward physical activity early in life, it is also essential that children learn to value themselves and develop a strong self-esteem. Without such positive influences, children and adolescents may develop disordered eating habits, which include the use of diet pills, laxatives, and excessive exercise. These disordered eating habits may manifest themselves as clinical eating disorders, such as anorexia and bulimia. It is of great importance that children receive support and positive influences from family, peers, and school to develop a healthy self-image and prevent the formation of disordered eating habits and eating disorders.

Eating Disorders and Disordered Eating: A Global Perspective

The continuous progression of the prevalence of eating disorders (ED) is a cause of concern during the last decades, and epidemiologic research has shown different increases between countries. Food is as well a psychological need that presents interindividual differences such as preferences/rejections to foods, healthy/unhealthy dietary habits, and worries about the shape, which result in “body dissatisfaction.” Thus, dieting and compensatory behaviors to control weight are acquired as normal behaviors by the general population increasing the risk to suffer from ED. In addition, healthy people and other atypical disorders are strongly influenced by emotions in their eating behaviors, not only EDs.
