Physical Activity Profiles of Attention-Deficit/Hyperactivity Disorder Symptoms Among Preschool Children

This study compared physical activity levels in 18 preschoolers with ADHD symptoms and 66 typically developing children using objective actigraphy monitoring over five school days. Children with ADHD symptoms engaged in significantly less light, moderate, and moderate-to-vigorous physical activity, suggesting reduced PA may be a behavioral marker of ADHD in early childhood.
