A within-subject examination of grandparents’ physical activity and sedentary behavior levels in the presence or absence of grandchild care provision

Table 6 Differences in PA and SB levels during a care moment vs. a non-care moment

	Estimates (95% CI)	p-value
Light intensity physical activity (LIPA)^a
Non-care moment (Ref. = Care moment)	0.75 (0.67; 0.85)	< 0.001*
Moderate-to-vigorous intensity physical activity (MVPA)^b
Non-care moment (Ref. = Care moment)	1.31 (1.03; 1.57)	0.029*
Sedentary behavior (SB)^a
Non-care moment (Ref. = Care moment)	1.33 (1.19; 1.50)	< 0.001*

^a Generalized linear mixed models with Beta variance and logarithmic link functions; ^b Generalized linear mixed models with Gamma variance and logarithmic link functions; Ref.: reference category; Values represent exponentiated regression coefficients and confidence intervals; *: significantly different (p ≤ 0.05) from the care moment
