  1. Reference groups are shown in parentheses. Design-based sample weights were applied prior to analyses. Two-way interactions were tested for all significant predictors but none were retained as contributing factors based on AIC selection
  2. SR, self-reported; HW, healthy weight; UW, underweight; OW, overweight; OB, obesity
  3. aIn Model 1, candidate predictors with empty cells were removed during the AIC selection procedure as non-contributing factors
  4. bIn Model 1, depressive symptoms and self-esteem were not significant alone but were retained during AIC selection as contributing factors
  5. cIn Model 2, African American and Other race/ethnic categories were not significant (shown above) but were retained during AIC selection because the class variable overall was a contributing factor
