BMI, body mass index; SDS, standard deviation score
Data are given as means with 95% confidence intervals unless stated otherwise.
a p-values were calculated using the Chi-square test of goodness of fit
b p-values were calculated using the Chi-square test of independence
c p-values were calculated with multiple regression analyses adjusting for socioeconomic group, sex, and residence of the child. Parent baseline BMI and child treatment time were log-transformed prior to testing due to skewed distributions.
