Relative Odds of Unrecognized Mobility Deficits in 70- to 79-Year-Old Men and Women by Walking Frequency and Selected Demographic and Behavioral Attributes.

	Men			Women
Attributes	OR (95% CI)	OR (95% CI)	OR (95% CI)	OR (95% CI)
Walks <30 min/wk	1.30 (1.02–1.66)	1.19 (0.93–1.53)	2.04 (1.65–2.52)	1.67 (1.34–2.09)
Age, y		1.09 (1.05–1.14)		1.11 (1.07–1.15)

Notes: Persons with unrecognized mobility deficits constitute those who were either excluded from the Long Distance Corridor Walk—that is, had a medical contraindication to exertion, were unable to complete the 400-meter walk, or needed >7 minutes to walk 400 meters as quickly as possible.

OR = odds ratio; CI = confidence interval.
