Home-Based Exergaming Intervention

This study will employ a 3-arm randomized clinical trial to determine the effects of a 6-month home-based exergaming intervention on preschoolers' physical activity, health-related fitness, cognition, and screen time, across time, at 3, 6 and 12 months, and as an exploratory outcome, will explore the moderating effects of parent involvement and physical home environment on the intervention role of exergaming across time. Briefly, a total of 330 child-parent dyads from the Twin Cities area in Minnesota will be individually randomly assigned to: 1) an exergaming intervention group (30 min. per session, 5 sessions exergaming play per week for a 6-month period); 2) a traditional PA group (phone consultations and workshops for parents to offer 5 times 30 min. PA at home for 6 months); and 3) an attention control group (continue with usual activities at home with emailed PA tips).
