Physical activity, sedentary time, and sleep from childhood to young adulthood: a seven-wave cohort study of within-person relations.

ABSTRACT:

Study objectives

To determine whether within-person changes in total physical activity (PA), moderate-to-vigorous physical activity (MVPA), and sedentary time from ages 6 to 18 predict changes in sleep duration and insomnia symptoms, and vice versa.

Methods

Seven waves of biennially collected data from a birth cohort study were used, capturing ages 6-18 years (n = 880). Every second year, objective data on PA, sedentary time, and sleep duration were collected using accelerometers, while insomnia symptoms were assessed through clinical interviews. Random Intercept Cross-Lagged Panel Models were estimated to test the within-person relations between PA/MVPA/sedentary time and sleep. Potential sex and age differences were also examined.

Results

We found no evidence for wi
