Do physical activity and electronic screen behaviours influence cognitive and psychosocial development in preschool children?

学龄前儿童缺乏身体活动和以屏幕为基础的娱乐活动的水平高得惊人，但人们对这些行为对幼儿期认知和心理社会发展的独立影响知之甚少。该项目将调查学龄前儿童体育活动与屏幕娱乐、认知和心理社会发展之间的关系。研究结果将确定这些行为对幼儿发展结果的影响程度和类型。这些知识将有利于家长、教育工作者、卫生专业人员和政府制定和实施以证据为基础的战略和政策，使幼儿有一个最好的人生开端。

Levels of physical inactivity and screen-based entertainment are alarmingly high among preschool children, yet little is known about the independent effects of these behaviours on cognitive and psychosocial development during early childhood. This project will investigate the associations between physical activity and screen-based entertainment and cognitive and psychosocial development in preschool children. The findings will identify how much and which types of these behaviours influence developmental outcomes in young children. This knowledge will benefit parents, educators, health professionals and governments to develop and implement evidence-based strategies and policies to give young children the best start in life.
