Associations between Affect, Physical Activity, and Anxiety Among US Children During COVID-19

Abstract

There is increasing concern regarding how the COVID-19 pandemic may impact the psychological and physical health of children. To date, studies on mental health during the pandemic in children are limited. We investigated links between activity levels and psychological outcomes in children during the height of the "stay-at-home" measures. We found that children had anxiety scores that were more than 5 standard deviations greater than normative values from healthy pediatric populations prior to the pandemic, and 94% of children exceeded the American Academy of Pediatrics recommendations on leisure screen time. Positive affect and physical activity were associated with reduced anxiety levels in children during the pandemic. These findings highlight the important mental health benefits of maintaining positive affect, engaging in physical activity, and limiting leisure screen time for children, especially during stressful periods.
