Hazard Ratios Relating Baseline Principal Component Scores to MMD Within Intervention Groups

Models	Predictor	PA HR (95% CI)	HE HR (95% CI)
Unadjusted	Lifestyle movement	0.67 (0.56 to 0.81)	0.68 (0.58 to 0.80)
	Sustained MVPA	0.73 (0.57 to 0.94)	0.62 (0.49 to 0.78)
	Body positioning	0.89 (0.75 to 1.06)	0.94 (0.81 to 1.10)
Adjusted*	Lifestyle movement	0.74 (0.61 to 0.89)	0.74 (0.62 to 0.88)
	Sustained MVPA	0.82 (0.63 to 1.05)	0.69 (0.54 to 0.87)
	Body positioning	0.94 (0.79 to 1.13)	0.99 (0.84 to 1.15)

Notes: All models stratified the baseline hazard on sex.

*Adjusted for baseline age, BMI, race/ethnicity, SPPB, history of high blood pressure, CVD, arthritis, lung disease, history of fracture, and diabetes. BMI = body mass index; CI = confidence interval; CVD = cardiovascular disease; HE = health education; HR = hazard ratio; PA condition = physical activity condition; MMD = major mobility disability; MVPA = moderate-to-vigorous physical activity; SPPB = short physical performance battery.
