MVPA, moderate-vigorous physical activity
Values are unadjusted means (SD) or n (%) for the dichotomous outcome of loss of 0.25 zBMI based on observed (non-imputed) cases.
Adjusted for child sex, race/ethnicity, age, and baseline value of the outcome.
Models compared change in the home-delivered treatment to the reference category clinic-delivered group, with multiple imputation for missing values, adjusted for child sex, race/ethnicity, age, and baseline value of the outcome. Values are coefficients (standard error) for continuous outcomes, and odds ratios with 95% confidence intervals for the dichotomous outcome of loss of 0.25 zBMI.
Family Nutrition and Physical Activity total score, with lower scores (possible range: 20–80) being less favorable.
