Bold typeface indicates significance (p<0.05). Data are for participants with ≥1 valid weekday and ≥1 valid weekend day at ≥ 600 mins, and with valid wear time (>0 mins) for each weekday period. * For level of education ‘≥ Degree level’ refers to a parent being qualified to university degree level or higher. All adjusted for gender, BMI, minutes of daylight after 3.00pm, and accelerometer wear time for that period. Before school and afterschool sedentary time additionally adjusted for school travel method to or from school respectively.
