*p < 0.05; **p < 0.005

^aSeparate logistic regression models were fit for each outcome variable Correct weight perception (accurate) as reference

^bAge, BMI, household income, and place of residence were controlled for in the models

^cBecause of multiple comparisons (n = 10), a p-value < 0.005 was considered significant using Bonferroni correction
