Background: Demographic correlates of movement behaviours in infants are unclear. Purpose: Examine the longitudinal associations between demographic correlates and movement behaviours (i.e., tummy time, restrained time, reading time, screen time, sleep time) in infants. Methods: Participants were 411 parents of infants from the Early Movers project in Edmonton, Canada. Movement behaviours, infant and parental age, and non-parental care time were assessed using a parental questionnaire at 2, 4, and 6 months of age. Other infant and parental demographic variables were assessed at 2 months of age. Linear and generalized linear mixed models were conducted. Results: Infant age (days) or age2 was positively with tummy time, reading time, and screen time as well as negatively associated with sleep time. Caucasian infants and those with older parents had less tummy time and an increased likelihood of having reading time. Infants of the most educated parents also had lower tummy time. Higher parent education and more siblings were associated with no screen time and longer sleep in infants. Infants with immigrant parent(s) were less likely to have reading time. No associations were found for infant sex, non-parental care, and parental marital status. Conclusion: Movement behaviours changed throughout infancy and no single demographic group had healthy patterns for all movement behaviours. Therefore, a healthy balance of movement behaviours should be promoted in all infants.
