Associations between development of sarcopenia subcomponents and sleep duration at baseline by logistic regression models

Variable	Lower muscle mass (n = 3518)		Slow gait (n = 3408)		Lower grip strength (n = 3420)
	OR (95% CI)	P	OR (95% CI)	P	OR (95% CI)	P
Sleep duration
Short	0.99 (0.45–2.14)	0.970	0.89 (0.62–1.29)	0.541	0.91 (0.62–1.32)	0.616
Medium	ref.		ref.		ref.

Adjusted for age (<75 or ≥75 years), sex, BMI (<18.5, 18.5–24.9, or ≥25 kg/m²), education (<10 or ≥10 years), number of medications (<5 or ≥5), GDS score (<6 or ≥6), MMSE score (<24 and ≥24), medical history, current drinking habit, current smoking habit, and physical inactivity. Each analysis was conducted after excluding participants with the component of sarcopenia at the first wave.

CI, confidence interval; OR, odds ratio.
