a Assessed using the Behavioral Assessment System for children (BASC-2) [34 ]
a Mean difference (95% CI) estimated using regression models adjusted for randomised group, sex, maternal education, household deprivation, primiparous, and BMI z-score at 5 years of age, in units of standard deviations. Greater scores indicate higher levels of depression, anxiety, or resilience
b Proportions who met the first physical activity guideline at 2, 3.5, and 5 years of age were too high to allow estimation of mean differences (94.1, 97.1, and 98.4%, respectively)
c Second physical activity guideline applies only to children aged 3 – 5 years
d No screen time (1 – 2 years) or 60 min maximum screen time (3 – 5 years). Not measured at 3.5 years
e Not being restrained in a car seat or stroller for > 60 min at a time, on at least 3 days a week (1 – 2 years). The proportion who met this guideline at 2 years of age was too high to allow estimation of mean differences (96.8%). Not measured at 3.5 years
f 11 – 14 h (1 – 2 years) or 10 – 13 h (3 – 5 years). The proportion who met this guideline at 2 and 3.5 years of age and at 2 or more time points was too high to allow estimation of mean differences (92.9%, 95.6%, and 92.6% respectively)
g Having a consistent sleep time or consistent wake time defined as within-person standard deviation of < 30 min
h The proportion who met this guideline at two or more time points was too low to allow estimation of mean differences (9.7%)
