The influence of health-promoting schools on the students’ active and sedentary behaviour by Alexandra Valencia-Peris, Lucia Sanchis-Francés, Carlos Chinchilla-Ramírez

“…Two questionnaires were used: the Physical Activity Questionnaire to assess physical activity levels and levels and the Young Leisure Sedentary Behaviour Questionnaire to assess sedentary time. The results show that, regardless of school type: a) the vast majority did not comply with the guidelines, b) boys spent more time in physical activity and screen time than girls, and c) physical activity decreased and screen time increased as students progressed through the educational stage. …”
