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 4 Mean difference in the children’s change in sedentary minutes per day between Year 1 and Year 4 associated with parents’ change in sedentary time between Year 1 and Year 4 using multiple imputation (N = 685)^a

Exposure		Child’s change in sedentary time Year 1 to Year 4 (mins/day)
Exposure		All Mean difference (95% CI)	Boys Mean difference (95% CI)	Girls Mean difference (95% CI)	P for gender interaction
Parent’s change in sedentary time Year 1 to Year 4 (mins/day)		N = 685	N = 323	N = 362
Female parent	Model 1	0.03 (−0.14, 0.20)	−0.03 (−0.25, 0.18)	0.11 (−0.17, 0.40)	0.40
Female parent	Model 2	0.03 (−0.14, 0.20)	−0.05 (−0.26, 0.17)	0.12 (−0.14, 0.39)	0.32
Male parent	Model 1	0.01 (−0.11, 0.12)	0.06 (−0.13, 0.25)	−0.05 (−0.26, 0.16)	0.35
Male parent	Model 2	0.00 (−0.12, 0.12)	0.07 (−0.12, 0.26)	−0.06 (−0.26, 0.15)	0.30

^aModel 1 is adjusted for child’s age at Year 1 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 1
