Association of number of steps or daily gait speed with prefrailty in the binomial logistic regression models.

Model	Group	Crude		Adjusted+
		Odds ratio (95% CI)	Significant difference	Odds ratio (95% CI)	Significant difference
Number of steps	Low Steps (n = 796)	Reference	*p < 0.001	Reference	*p < 0.001
	High Steps (n = 896)	0.515 (0.422–0.629)		0.556 (0.452–0.684)
Daily gait speed	Low Speed (n = 854)	Reference	*p < 0.001	Reference	*p = 0.004
	High Speed (n = 838)	0.664 (0.545–0.808)		0.738 (0.599–0.909)

⁺Adjusting variables were age, sex, and body mass index (BMI). CI, confidence interval; *p < 0.05.

Low Steps: Participants with a number of steps of < 6342.2 steps/day.

High Steps: Participants with a number of steps of ≥ 6342.2 steps/day.

Low Speed: Participants with a daily gait speed of < 106.3 cm/s.

High Speed: Participants with a daily gait speed of ≥ 106.3 cm/s.
