  1. *p < 0.05; **p < 0.005
  2. aSeparate logistic regression models were fit for each outcome variable Correct weight perception (accurate) as reference
  3. bAge, BMI, household income, and place of residence were controlled for in the models
  4. cBecause of multiple comparisons (n = 10), a p-value < 0.005 was considered significant using Bonferroni correction
