  1. Note. B unstandardized regression coefficient, BCa 95% CI 95% bias corrected and accelerated confidence interval, BMI-SDS body mass index standard deviation score; BCa 95% CI, standard error and p>-values are based on 2,000 bootstrap samples; a positive B value indicates that this (lower) category predicts higher WBIS-C scores compared to the category of higher education degree
  2. a bivariate coded: 0 = female, 1 = male
  3. b education level was dummy coded (3 dummy variables (categories 1–3) with highest level (category 4) as a reference [Ref])
