A scalable school‐based intervention to increase early adolescents' motor competence and health‐related fitness
2023
Schools are key settings for the promotion of students' physical activity, fitness, and motor competence. The purpose of our study was to investigate the efficacy of a 5-month-long intervention program that aimed to increase students' motor competence and health-related fitness during school days. We conducted a quasi-experimental study with 325 Finnish Grade 5 (Mage = 11.26, SD = 0.33) students from five schools. Two schools were allocated to the intervention group and three schools to the control group. The intervention consisted of three components: (a) weekly 20 min session during regular PE lessons, (b) weekly 20 min session during recess, and (c) daily 5-minute-long classroom activity…
Actualisation des références nutritionnelles françaises en vitamines et minéraux
2021
En 2016, l’Anses a proposé une mise à jour des références nutritionnelles pour la population adulte (femmes de 18 à 54 ans et hommes de 18 à 64 ans) dans le cadre de l’actualisation des repères de consommation alimentaire (saisine 2012-SA-0103). Par la suite, des rapports dédiés aux repères de consommation alimentaire pour les populations spécifiques (personnes âgées, enfants, femmes enceintes et allaitantes) ont été publiés en 2019, sans toutefois quede nouvelles références nutritionnelles ne soient définies par l’agence.Par ailleurs, la mise à jour de 2016 n’a concerné que les vitamines et minéraux indispensables pour lesquelles des données de consommation étaient disponibles. De ce fait,…
Pašuztvertā intelekta saistība ar akadēmisko pašefektivitāti un akadēmiskajiem sasniegumiem vispārizglītojošo skolu jauniešiem
2020
Pētījuma mērķis bija izpētīt saistību starp pašuztverto intelektu, akadēmisko pašefektivitāti un akadēmiskajiem sasniegumiem vispārizglītojošo skolu jauniešiem, kā arī veikt atšķirību izpēti skolēnu izlases apakšgrupās ar atšķirīgiem pašuztvertā intelekta domāšanas veidiem. Pētījuma izlasi veido 165 jaunieši vecumā no 15 līdz 19 gadiem (M = 16,75, SD = 0,90), no tiem 80 (48,50%) meitenes un 85 (51,50%) zēni, kas mācās 10.-12. klasē piecās vidusskolās. Pētījumam piemīt aprakstošs korelatīvs un starpgrupu analīzes dizains. Pētījumā tika adaptētas un izmantotas divas aptaujas - Pašuztvertā intelekta skala bērniem (Implicit Theories of Intelligence Scale for Children (ITIS), Blackwell, Trzesnie…
Students' abilities to evaluate the credibility of online texts: The role of internet‐specific epistemic justifications
2021
Previous evaluation studies have rarely used authentic online texts and investigated upper secondary school students' use of evaluation criteria and deep reasoning. The associations between internet-specific epistemic justifications for knowing and credibility evaluation of online texts are not yet fully understood among adolescents. This study investigated upper secondary school students' (N = 372) abilities to evaluate self-selected authentic online texts and the role of internet-specific epistemic justifications in students' evaluation performance when solving a health-related information problem. Students selected three texts with Google Custom Search Engine and evaluated their credibil…
Leisure-time physical activity, body mass index, and waist circumreference : a longitudinal twin study from adolescence to adulthood
2010
ABSTRACT LEISURE-TIME PHYSICAL ACTIVITY, BODY MASS INDEX, AND WAIST CIRCUMFERENCE: A LONGITUDINAL TWIN STUDY FROM ADOLESCENCE TO ADULTHOOD Minna Kujala Master’s Thesis of Sport Medicine The University of Jyväskylä The Faculty of Sport and Health Sciences Department of Health Sciences 2010 Pages: 54, 8 appendixes The aim of this study was to investigate the effects of persistence and changes in the frequency of leisure- time physical activity on body mass index and waist circumference from adolescence to adulthood. Also, this study investigates the effect of the intensity of physical activity on body mass index (BMI) and waist circumference in adulthood. Participants in the study, members of…
The feasibility of working memory tablet tasks in predicting scholastic skills in classroom settings
2019
Cognitive assessment in natural group settings facilitates data collection but poses threats to the validity. In this study, tablet‐based working memory (WM) tasks, the counting span, and reading span were used in predicting 12‐year‐old children's (N = 837) scholastic skills and fluid intelligence in a classroom with environmental noise. WM tasks had excellent internal consistency, correlated with scholastic skills, and accounted for more of the variance in cognitive performance (grade point average, fluid intelligence, scholastic skills) compared with individually administered (n = 190) digit span task. Furthermore, the multilevel analysis revealed that compared with the classrooms with no…
How physical activity, fitness, and motor skills contribute to math performance: Working memory as a mediating factor
2021
Purpose The purpose of this study was to examine whether physical activity, fitness and motor skills have indirect association with math performance via cognitive outcomes and if so, through which aspects of cognition? Methods This study comprised 311 6th–9th grade adolescents (12–17y [M age=14.0y], 59% girls) from seven schools throughout Finland in 2015. Math performance was measured via a teacher-rated math achievement and the Basic Arithmetic test. Cognitive functions were measured by broad cognitive test battery. Physical activity was assessed with a self-reported questionnaire and a hip-worn accelerometer. Aerobic fitness was estimated using a maximal 20-m shuttle run test, muscular f…
School-based group intervention in attention and executive functions: Intervention response and moderators
2022
ObjectiveThis study investigated the effects of a school-based skill-training intervention in attention control and executive functions for pupils with hyperactivity-impulsivity (H-I) and cognitive control (CC) deficits. The main aim was to examine whether the intervention differently influenced H-I and CC, and whether cognitive abilities or conduct problems moderated response to the intervention.MethodElementary school pupils from 41 schools participated the study and were divided into an intervention group (n = 71) and a waitlist control group (n = 77). Intervention outcomes were assessed with an inventory assessing executive function difficulties (including H-I and CC) completed by class…
An Overview on the Associations between Health Behaviors and Brain Health in Children and Adolescents with Special Reference to Diet Quality.
2020
Unhealthy diet has been associated with overweight, obesity, increased cardiometabolic risk, and recently, to impaired cognition and academic performance. The aim of this review is to provide an overview of the associations between health behaviors and cognition and academic achievement in children and adolescents under 18 years of age with a special reference to diet quality. Dietary patterns with a low consumption of fish, fruits, and vegetables, and high in fast food, sausages, and soft drinks have been linked to poor cognition and academic achievement. The studies on the associations between the high intake of saturated fat and red meat and low intake of fiber and high-fiber grain produ…
