Respondents accurately perceived themselves as overweight.
Number of respondents with data available for the given characteristic.
Binary variables were compared across groups using the Cochran-Armitage trend test. In those who were trying to lose weight, the weight loss goal, expressed in pounds and percentage of current weight, was compared across groups by using one-way analysis of variance and the time frame for achieving the weight loss goal was compared across groups by using the χ 2 test.
Multivariable logistic regression was performed to assess whether the given characteristics was associated with body mass index after adjusting for age and sex. For this analysis, BMI was modeled as a continuous variable and indings are summarized by presenting the odds ratio and corresponding 95% confidence interval for an increase in BMI of 5 kg/m2.
