Note: The total sample size varied for each of the physical performance measures due to NJ and LA sites not participating in the 40 ft walk, exclusion of women needing assistance on either the 40 ft walk or the 4 M walk, or missing data; n for 40 ft walk = 1309, n for 4 M walk = 1728, n for grip strength = 1760, n for chair stand = 1714, n for decile score = 1707, n for balance problem = 1746
