  • *Model 1: adjusted for age and sex; model 2: further adjustments for body mass index, limiting long-standing illness, household income and social class; model 3: further adjustments for time spent in active transportation to and from school, time spent in sporting or informal activities and moderate-to-vigorous physical activity time (accelerometer models only). Models with accelerometer sedentary time as the outcome were also adjusted for average accelerometer wear time on valid days.

  • †Generalised linear model coefficients; coefficients indicate mean differences (in daily sedentary time) between the reference category (quintile 1) and each of the other deprivation quintiles; for example, a value of five indicates that a specific category had an average daily sedentary time that is 5 min higher than the referent group.
