    Activity-rest circadian pattern and academic achievement, executive function, and intelligence in children with obesity
    (Wiley, 2020-10-23) Migueles, Jairo H.; Martínez Nicolás, Antonio; Cadenas Sánchez, Cristina; Esteban Cornejo, Irene; Muntaner Mas, Adrià; Mora González, José; Rodríguez Ayllón, María; Madrid, Juan Antonio; Rol de Lama, María de los Ángeles; Hillman, Charles H.; Catena, Andrés; Ortega, Francisco B.; Fisiología
    This study aimed to analyze the associations of activity-rest pattern indicators with academic achievement, executive function, and intelligence and to explore whether these associations are mediated by the total gray matter volume among children with overweight/obesity. Ninety-five children (10 ± 1 year, 37 girls) with overweight/obesity (based on the World Obesity Federation body mass index cutoff points) were included in this cross-sectional study. Hip- and wrist-worn ActiGraph GT3X + accelerometers were used to assess the activity-rest pattern. Interdaily stability (IS), intradaily variability (IV), the mean value of the lowest 5 hours (L5), and the mean value of the maximum 10 hours (M10) of activity and their respective timing (TL5, TM10) were used as indicators of the activity-rest pattern throughout the day. Chronotype and social jetlag were used as indicators of circadian preference. Academic achievement, executive function, and intelligence were assessed with standardized tests. Gray matter volume was acquired by magnetic resonance imaging (MRI). IS was positively associated with executive function (β = 0.244, P = .014). IV was negatively associated with mathematics and academic applications (β: −0.211 to −0.238, P’s ≤ .026). Later TM10 in the day was related to lower writing, academic skills, and intelligence (β: −0.229 to −0.271, P’s ≤ .025). None of the associations found were mediated by gray matter volume. A non-fragmented and stable activity-rest pattern and earlier physical activity in the day were associated with better academic achievement, executive function, and intelligence in children with overweight/obesity. Further studies are required to corroborate or contrast our findings.

    The influence of physical activity, diet, weight status and substance abuse on students’ self-perceived health.
    (MDPI, 2020-02-21) Moral García, José Enrique; Agraso López, Antonio David; Ramos Morcillo, Antonio Jesús; Jiménez, Alfredo; Jiménez Eguizábal, Alfredo; Enfermería
    The objective of this study was to determine the level and relationship between the self-perceived health of adolescents in relation to the level of practice of physical activity, adherence to the Mediterranean diet, weight status and consumption of substance abuse, such as alcohol and tobacco. A total of 516 adolescent students between the ages of 12 and 16 completed a series of questionnaires to assess their health, physical activity, compliance with the Mediterranean diet and alcohol and tobacco consumption. Adolescents who practice more physical activity have better health and greater adherence to the Mediterranean diet. The level of health is higher among adolescents with greater adherence to the Mediterranean diet, evidencing better health among those who consume less tobacco. These results show the need to involve the educational community, families and the media to promote healthy lifestyle habits that can help physical activity and sports professionals in the development of theoretical–practical proposals aimed at improving the health of students.
