OR odds ratio, CI confidence interval, SES socioeconomic status
aIndicates the percentage of normal-weight participants in each group perceiving themselves to be too heavy
bEntered into the model as a continuous variable
cVariables in the models are: age (years), gender, ethnicity, SES, residence and weight status category
