Table 2 Associations between movement behaviors and BMI z-scores inside and outside of child care

From: The association between physical activity, sedentary behavior, sleep, and body mass index z-scores in different settings among toddlers and preschoolers

  1. β (95 % CI) = unstandardized regression coefficient (95 % confidence interval); LPA light physical activity, MVPA moderate-vigorous physical activity; Model 1 = accelerometer variables controlled for total wear time; Model 2 = model 1 and variables controlled for age, sex, and parental education; * = P < 0.05
