Oral Health Factors Associated with Frailty Status

	Prefrail		Frail
	OR	95% CI	OR	95% CI
Model 1*
Chewing difficulty	1.64	1.33–2.03	3.10	2.48–3.86
Number of teeth	0.99	0.98–1.01	0.99	0.97–1.00
Model 2†
Chewing difficulty	1.49	1.19–1.86	2.68	2.08–3.44
Number of teeth	1.00	0.98–1.01	0.99	0.97–1.01

Notes: Logistic regression analysis was performed to identify factors associated with frailty status with non-frail as the reference. *Model 1: Adjusted for age, sex. ^†Model 2: Adjusted for age, sex, body mass index (BMI), smoking status, income quartile, level of education, hypertension, diabetes, stroke, and cardiovascular disease (myocardial infarction [MI], angina).

Abbreviations: CI, confidence interval; OR, odds ratio.
