AIM: To investigate longitudinal changes of habitual physical activity (HPA) and
sedentary time in children with cerebral palsy (CP) aged 1 year 6 months to 5
years across all functional abilities. METHOD:
At study entry, 95 children
(62 males, 33 females) were classified using the Gross Motor Function Classification
System (GMFCS) at levels I (50), II (9), III (16), IV (6), and V (14). Physical
activity was recorded on a total of 159 occasions at four possible time points: 1 year 6 months to 2 years; 2 years 6 months to 3 years; 4 years; and 5 years using
ActiGraph for 3 days. Mixed-effects regression models were used for analyses.
RESULTS: Participants classified at GMFCS levels I and II had stable HPA as they
aged. HPA significantly decreased at 5 years in children classified at GMFCS
levels III to V. Sedentary time significantly increased at 4 years and 5 years in
all participants. Annual HPA significantly reduced in children classified at
GMFCS levels III to V (-123 counts/min, 95% confidence interval [CI] -206 to -40)
while annual sedentary time significantly increased in all participants (GMFCS
levels I-II: 2.4%, 95% CI 0.7-4.1; GMFCS levels III-V: 6.9%, 95% CI 4.6-9.2).
INTERPRETATION: Children with CP at all GMFCS levels should be encouraged to be
physically active from early childhood as HPA levels start to decline from 4
years. Breaks in sedentary time are required for all children with CP from the age of 3 years.
