One important determinant of childhood physical activity and sedentary behavior may be that of motor development in infancy. The
present analyses aimed to investigate whether gross and fine motor delays in infants were associated with objective and self-reported
activity in childhood. Data were from the UK Millennium Cohort Study, a prospective cohort study, involving UK children born on or
around the millennium (September 2000 and January 2002). When children were 9 months old, parents reported children’s fine and
gross motor-coordination, and at 7 years, sports club attendance and daily TV viewing time. Children’s physical activity was
measured using accelerometers at 7 years. Adjusted regression models were used to examine associations between delayed motor
development and accelerometry measured moderate-to-vigorous physical activity and sedentary behavior, and parent-reported
sport club attendance and TV viewing time. In this sample (n=13,021), gross motor delay in infancy was associated with less time in
moderate-to-vigorous physical activity (B 5.0 95% confidence interval [CI] 6.8, 3.2) and more time sedentary (B 13.5 95% CI
9.3, 17.8) in childhood. Gross and fine motor delays during infancy were associated with a reduced risk of having high attendance at
sports clubs in childhood (both relative risk [RR] 0.7, 95% CI 0.6, 0.9). Fine motor delays, but not gross delays, were also associated
with an increased risk of having high TV viewing time (RR 1.3 95% CI 1.0, 1.6). Findings from the present study suggest that delays in
motor development in infancy are associated with physical activity and sedentary time in childhood.
