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 5 Mean difference (95% confidence interval) in the children’s change in moderate-to-vigorous physical activity minutes per day between Year 1 and Year 4 associated with parents’ change in moderate-to-vigorous physical activity between Year 1 and Year 4 using multiple imputation (N = 685)^a

Exposure		Child’s change in MVPA 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 MVPA Year 1 to Year 4 (mins/day)		N = 685	N = 323	N = 362
Female parent	Model 1	0.06 (−0.04, 0.16)	0.14 (−0.03, 0.30)	0.01 (−0.13, 0.15)	0.22
Female parent	Model 2	0.06 (−0.05, 0.17)	0.14 (−0.03, 0.31)	0.01 (−0.13, 0.16)	0.28
Male parent	Model 1	0.02 (−0.03, 0.06)	0.02 (−0.03, 0.08)	0.00 (−0.10, 0.11)	0.73
Male parent	Model 2	0.02 (−0.03, 0.07)	0.02 (−0.04, 0.08)	0.00 (−0.12, 0.12)	0.73

^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
