Notes: Model 0: Crude model. Model 1: Adjusted for age, sex, race, marital status, education, and poverty-income ratio. Model 2: Additionally adjusted for drinking, smoking, total energy intake, and weekly physical activity level. Model 3: Additionally, adjusted for hyperlipidemia, DM, arthritis, CVD, thyroid problems, liver problem, hypertension, CKD, and cancer. DM, diabetes; CVD, cardiovascular disease; CKD, chronic kidney disease; BRI, body roundness index; BMI, body mass index; SD, standard deviation; HR, hazard ratio; CI, confidence interval
