  1. BCIS: Beck Cognitive Insight Scale, BMI: Body mass index, HLOE: Highest level of education; RBANS: Repeatable Battery for the Assessment of Neuropsychological Status
  2. HLOE Reference category = 0 = Primary school or less, 1 = Some secondary school, 2 = Completed secondary school
  3. Weight changes: Reference category = 0 = No significant weight changes, 1 = Weight decreased, 2 = Weight increased
  4. *: relationship with correct perception of body weight - p ≤ 0. 05
  5. **: relationship with correct perception of body weight - p ≤ 0.01
  6. Note: Supplementary Table 1 compares these results to regression results when those who misperceived their weight to be higher were included in the analysis
