Association of parents’ and children’s physical activity and sedentary time in Year 4 (8–9) and change between Year 1 (5–6) and Year 4: a longitudinal study

Table 2 Mean difference (95% confidence interval) in the children’s average sedentary minutes per day in Year 4 associated with parents’ sedentary time in Year 4 and Year 1 using multiple imputation data^a

Exposure		Child’s sedentary time in Year 4 (mins/day)
Exposure		All Mean difference (95% CI)	Boys Mean difference (95% CI)	Girls Mean difference (95% CI)	P for gender interaction

^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
