Sleep and screen time are more linked with academic achievement than physical activity

Dr. JP Chaput published “Adherence to 24-hour movement guidelines and academic performance in adolescents” in the Journal of Public Health. The aim of the study was to examine the association between meeting combinations of the Canadian 24-h movement guidelines and academic performance in adolescents. 5.1% of students met all three movement guidelines, whereas 39.0% did not meet any. Middle school students who met all three guidelines or either the screen time or sleep guideline, displayed better academic performance than those who met none of the guidelines. High school students who met the screen time and sleep guidelines showed better academic performance than those who did not meet any guidelines.
