Associations of age and gender with activity and sleep.
Associations between age/gender and activity/sleep (measured by actigraphs) in 66 healthy children aged 5-12 y were studied. With increasing age, daytime motor activity and total sleep time decreased and activity pattern changed. No gender differences were found. It was concluded that in this age group there is an age-dependent change in the amount and pattern of motor activity and sleep due to developmental and/or environmental factors.
