The associations between longitudinal changes in anthropometric measures and frailty^a

Variables	Unadjusted model	Multivariable-adjusted model
	OR (95% CI)	OR (95% CI)
Waist-calf circumference ratio	2.25 (1.90–2.66)	1.74 (1.43–2.12)
Waist circumference, cm	1.01 (1.00-1.01)	1.03 (1.02–1.04)
Calf circumference, cm	0.92 (0.91–0.94)	0.95 (0.93–0.97)

OR odd ratio, CI confidence interval

Notes: ^a The generalized estimation equation was used to explore the association between longitudinal changes in anthropometric measures over time and frailty. The multivariate model was adjusted for age, sex, marital status, education, residence, living arrangement, economic status, smoking status, drinking status, regular exercise status, sleep time, and body mass index, and further adjusted for calf circumference in the waist circumference model and waist circumference in the calf circumference model
