Multivariable AORs estimated using continuation ratio logit model with coefficients freely varying across stages. Analysis incorporated sample weights and accounted for complex design of NHANES.
BMI at examination and BMI at 25 effect sizes scaled for 5‐kg/m2 units.
BMI at examination calculated with measured height and weight.
BMI at 25 calculated with measured height and recalled weight at age 25.
Age effect size scaled for 10‐y unit.
Self‐reported diabetes, arthritis, and insurance status.
High school or equivalent includes GED.
Physical difficulty included 6 measures of physical function indicated by difficulty walking a quarter of a mile; walking up 10 steps; stooping, crouching, or kneeling; lifting or carrying 10 lb; walking between rooms on the same floor; or standing up from an armless chair.
AOR, adjusted odds ratio; GED, general equivalency diploma; NHANES, National Health and Nutrition Examination Survey.
