简要总结
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).

Change in physical activity levels
时间窗: 0, 3, 12 months (follow-up)
Preschoolers' 5-day daily PA levels will be assessed using ActiGraph Link GT9X accelerometers (Pensacola, FL) at each testing cycle. The Link is lightweight and resembles a watch, and is a valid and reliable measure of PA among young children in free-living settings. Children will be instructed to wear the accelerometers on the non-dominant wrist at all times with the exception of time spent swimming for 3 weekday and 2 weekend days. In this project, activity counts will be set at 1-second epochs. Counts will be interpreted using empirically based cut points that define different PA intensities for preschoolers. Children's daily average minutes engaged in PA (MVPA and light PA) and sedentary behavior will be used as the outcome variables. Acceptable inclusion criteria for PA data will be recording of an average of 10 hours of accelerometer data per day. Compliance with wearing monitors will be facilitated according to Trost recommendations.
