Childhood obesity has become a major global health problem. Vitamin D deficiency and poor cardiorespiratory fitness are highly prevalent in children with overweight or obesity, but little is known about their relationships. In this study, we aimed to analyze the relationship between serum 25-hydroxyvitamin D (25(OH)D) and cardiorespiratory fitness parameters in prepubertal obese and overweight children. A cross-sectional design with a sample of 57 prepubertal children, aged 9–11 years, with overweight or obesity was used. The fasting concentration of 25(OH)D was analyzed with a chemiluminescent microparticle immunoassay. Fat and lean body masses were determined by using DXA. Maximal oxygen uptake (VO2max) was measured with the maximal treadmill test. A total of 68.4% of the sample had sufficient levels of 25(OH)D. As expected, their cardiorespiratory fitness was poor compared with that of normal-weight children, but 60% of the group exceeded the median obesity-specific reference values. No differences were found between the sexes for relative VO2max or 25(OH)D levels. Moreover, no correlations were found between 25(OH)D and body composition or cardiorespiratory parameters for sex or vitamin D groups. Vitamin D status seems not to be directly related to body composition or cardiorespiratory fitness in prepubertal overweight or obese children.

Attention deficit and hyperactivity disorder (ADHD) is commonly associated with disordered or disturbed sleep and the association of sleep problems with ADHD is complex and multidirectional. The purpose of this study was to analyze the relationship between sleep and academic performance, comparing children with ADHD and a control group without ADHD. Academic performance in Spanish, mathematics, and a foreign language (English) was evaluated. Different presentations of ADHD were considered as well as the potential difference between weekday and weekend sleep habits. The sample consisted of 75 children aged 6–12 in primary education. Accelerometry was used to study sleep, and school grades were used to gather information about academic performance. The results showed that ADHD influenced the amount of sleep during weekends, the time getting up at the weekends, weekday sleep efficiency, as well as academic performance. Given the effects that were seen in the variables linked to the weekend, it is necessary to consider a longitudinal design with which to determine if there is a cause and effect relationship.

El Trastorno por Déficit de Atención con o sin Hiperactividad (TDAH) es un trastorno neurobiológico en el que se presentan una serie de síntomas o patrones de indicadores más o menos estables como hiperactividad, impulsividad y déficit de atención que se empiezan a manifestar en la infancia, solapados en muchos casos con problemas comórbidos. En este artículo se presenta un estudio empírico, realizado con una muestra de 64 alumnos entre los 5 y 15 años de edad, con diagnóstico clínico en TDAH, cursando estudios desde 3º de Educación Infantil a 4º de Educación Secundaria Obligatoria, con una M de edad 10.27 años (DT=2.76), de los cuales 51 son niños y 13 son niñas. Para el estudio se ha empleado una metodología con técnicas cuantitativas, en la que los participantes fueron evaluados mediante el Cuestionario Five to Fifteen (FTF) de Kadesjö, con un cuestionario cumplimentado por sus padres que ofrece la posibilidad de descubrir los problemas propios de un niño con TDAH y aquellos que se pueden asociar. Se aplica el software SPSS para la obtención de los resultados de los 179 ítems correspondientes a los dominios y subdominios del TDAH. Con estos resultados se pretende definir el perfil de los dominios y subdominios del TDAH a través del cuestionario FTF. Entre los resultados hallados encontramos que algunas de las características clave de los niños que presentan este trastorno son las dificultades de aprendizaje y la problemática de estos niños con la interacción social.

(1) Background: Childhood obesity has become a main global health problem and active video games (AVG) could be used to increase energy expenditure. The aim of this study was to investigate the energy expenditure during an AVG intervention combined with exercise, differentiating by gender. (2) Methods: A total of 45 children with overweight or obesity (19 girls) performed an AVG intervention combined with exercise. The AVG used were the Xbox Kinect, Nintendo Wii, dance mats, BKOOL cycling simulator, and Nintendo Switch. The energy expenditure was estimated from the heart rate recorded during the sessions and the data from the individual maximal tests. (3) Results: The mean energy expenditure was 315.1 kilocalories in a one-hour session. Participants spent the most energy on BKOOL, followed by Ring Fit Adventures, Dance Mats, Xbox Kinect, and the Nintendo Wii, with significant differences between BKOOL and the Nintendo Wii. Significant differences between boys and girls were found, but were partially due to the difference in weight, VO2max, and fat-free mass. (4) Conclusions: The energy expenditure with AVG combined with multi-component exercise was 5.68 kcal/min in boys and 4.66 kcal/min in girls with overweight and obesity. AVG could be an effective strategy to increase energy expenditure in children and adolescents with overweight and obesity.
