a
From mixed-effects linear regression models adjusted for nesting of locations within participants and participants within block groups.
b
If a participant did not spend any time in a given location on school days or nonschool days, then the “percentage of location time in MVPA” variable was entered as missing. Thus, because mixed models were used, a participant who was missing a given location still contributed to estimating the parameters for the nonmissing locations.
