^aModel 1 is adjusted for child’s age at Year 4 and gender; Model 2 is additionally adjusted for the child’s BMI z score, number of siblings, household IMD score and the female/male parent’s age and BMI at Year 4 for models with parent’s sedentary time in Year 4 as the exposure, or for child’s BMI z score, number of siblings, household IMD score and the female/male parent’s age and BMI at Year 1 for models with the parent’s sedentary time in Year 1 as the exposure
