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

Table 5 Crude means of PA and SB levels during a care moment and a non-care moment

Outcome variables	Mean ± SD
Light intensity physical activity (LIPA) (% of time/moment)
Care moment	40.0 ± 11.9
Non-care moment	32.1 ± 13.8
Moderate-to-vigorous intensity physical activity (MVPA) (% of time/moment)
Care moment	4.2 ± 6.9
Non-care moment	5.5 ± 8.1
Sedentary behavior (SB) (% of time/moment)
Care moment	55.7 ± 12.9
Non-care moment	62.4 ± 15.6

SD: standard deviation; LIPA: light intensity physical activity; MVPA: moderate-to-vigorous intensity physical activity; SB: sedentary behavior. The symbol “%” is used to indicate a percentage. In this case, these percentages indicate the proportion of total time spent on physical activity (PA) and sedentary behavior (SB) relative to the total moment time (i.e., care moment or non-care moment). It indicates the proportion of time spent on PA and SB relative to 100 (i.e., corresponding with the total accelerometer wear time during the specific moment) and can help provide a general understanding of how much time was spent on these different activity levels
