Notes: All estimates control for time-in-attendance and clustering at the child and site level.
Boldface indicates statistical significance (p<0.05).
a
Model controlled for age, BMI, and race/ethnicity.
b
Two SDCs operated on a military base, and one in a strip mall
PA, physical activity; MVPA, moderate-to-vigorous physical activity; min/d, minutes per day; SDCs, summer day camps
