Relations among entertainment screen-based,educational sedentary behavior and inhibitory control in school-age children
Objective:To investigate the relations among entertainment screen-based sedentary behavior,edu-cational sedentary behavior,and inhibitory control in school-aged children.Methods:A total of 700 Chinese school-aged children(10-15 years old)were recruited.The Adolescent Sedentary Active Questionnaire was used to assess total sedentary time,entertainment screen-based sedentary time,and educational sedentary time.Executive function was measured by the Stroop task.Results:There were significantly negative associations between entertainment screen-based sedentary time and the accuracy of Stroop task in the congruent and incongruent condition(β=-0.15,-0.18),while there was significantly positive association between educational sedentary time and the reac-tion time of Stroop task in the incongruent condition(β=-0.09).Conclusion:The relationship between sedentary behavior and inhibitory control may vary depending on the type of sedentary behavior.Moreover,special emphasis should be placed onlimiting the entertainment screen-based sedentary behavior to promote cognitive development in school-aged children.
