MLM, Mixed linear model; S.E., standard error; df, degrees of freedom; BMI, body mass index.
a
Initial models were not adjusted for any covariate. Covariate models were adjusted for pubertal status, anxiety, depression, body fat percentage, BMI and age. Variables were standardized prior to analysis to allow for the interpretation of unstandardized coefficients as standardized coefficients. Total variance explained (i.e. R2) by the MLMs was calculated using pseudo R2 (Kenny et al. 2006).
