Effects of Parental Education on Screen Time, Sleep Disturbances, and Psychosocial Adaptation Among Asian Preschoolers: A Randomized Controlled Study.

Purpose: A recent increase in screen time during early childhood has adversely affected the sleep and psychosocial health of children; however, limited information is available regarding effective interventions to reduce the screen time among them. This study aimed to investigate the effect of a parental educational program on screen use, sleep quality, and psychosocial adaptation among preschoolers.

Design And Methods: A clustered randomized controlled study with a parallel-group design was conducted.

Differences in working memory as a function of physical activity in children.

Objective: Given previous research examining the relationship between physical activity (PA) and working memory in children has not taken into account of potentially confounders, this study specifically controlled for the effects of intelligence and fitness-related factors (i.e., aerobic and motor fitness) on this relationship.
