Preschoolers' Physical Activity, Screen Time and Compliance with Recommendations
Hinkley, Trina; Salmon, Jo; Okely, Anthony D.; Crawford, David; Hesketh, Kylie
Methods: Participants were 1004 Melbourne preschool children (mean age 4.5, range 3-5 years) and their families in the Healthy Active Preschool Years (HAPPY) Study. Physical activity data were collected by accelerometry over an eight-day period. Parents reported their child's television/video/DVD viewing, computer/internet and electronic game use during a typical week. A total of 703 (70%) had sufficient accelerometry data and 935 children (93%) had useable data on time spent in screen-based entertainment.
Results: Children spent 16% (approx. 127 mins/day) of their time being physically active. Boys and younger children were more active than were girls and older children, respectively. Children spent an average of 113 minutes per day in screen-based entertainment. Virtually no children (<1%) met both the Australian recommendations and 32% met both the NASPE and AAP recommendations.
Conclusion: The majority of young children are not participating in adequate amounts of physical activity and in excessive amounts of screen-based entertainment. It is likely that physical activity may decline and screen-based entertainment increase with age. Compliance with recommendations may be further reduced. Strategies to promote physical activity and reduce screen-based entertainment in young children are required.
