All values presented are β ± standard errors with p-values. Univariate model consists of individual baseline characteristics predictor with physical component scale of short-form 12 as the outcome. Multivariable modeling consists of all significant predictors with their β ± standard errors with p-values with and without the metropolitan statistical area * body mass index interaction term.
