Respondents were divided into six categories based on BMI and gender: normal weight men, normal weight women, overweight men, overweight women, obese men, and obese women. Cross-tabulations were used to compute the prevalence of each demographic characteristic and substance use disorder in each of the six groups. Prevalence rates were adjusted based on weighting to reflect general population demographics. Chi-square analysis examined omnibus differences among the six groups on categorical demographic variables, and simple regression analysis was used for continuous variables.
