Association of screen-based sedentary behavior with executive function in school-aged children: A functional near-infrared spectroscopy study
Screen-based sedentary behavior (SSB) is a significant risk factor for the health of school-aged children, and guidelines recommend limiting SSB to 2 hr per day. This study aimed to examine association and potential mechanisms between SSB and executive function (EF) by comparing Stroop performance and frontal hemodynamic responses between children with and without excessive SSB. A total of 70 children aged 10 to 15 years were recruited and divided into two groups: excessive screen time (≥2 hr/day; n = 35; ES group) and normal screen time (<2 hr/day; n = 35; NS group). The Chinese version of the Adolescent Sedentary Activities Questionnaire was used to assess SSB, whereas EF was evaluated using the Stroop task. The frontal hemodynamic responses during the Stroop task were measured using functional near-infrared spectroscopy. The results indicated that the ES group had lower accuracy, longer reaction times, and greater activation in the bilateral dorsolateral prefrontal cortex (DLPFC) and left pre-supplementary motor area (Pre-SMA) compared with the NS group. Furthermore, significant correlations were observed between Stroop performance and cortical activation in the left DLPFC and Pre-SMA. These findings demonstrate that excessive SSB is associated with poor EF, which may be explained by a decrease in neural efficiency of the left DLPFC and Pre-SMA.
期刊介绍:
The Journal of Experimental Child Psychology is an excellent source of information concerning all aspects of the development of children. It includes empirical psychological research on cognitive, social/emotional, and physical development. In addition, the journal periodically publishes Special Topic issues.
