Walking speed is a highly valid test , both at habitual and maximum speed .
Both habitual and maximum walking speeds are valid instruments , and they predict death , hospitalization/institutionalization , and decline in mobility
The number of available walking tests has increased dramatically over the past decades .
Therefore , it is highly important to help clinicians choose the most appropriate walking test for a specific setting .
This systematic review aim ed to critically evaluate the reliability , validity , and responsiveness of clinical walking speed in a broad population of elderly persons living in the community , sheltered housing , or institutions .
Correlates of attributing new disability to old age. Study of Osteoporotic Fractures Research Group.
OBJECTIVES To describe women who attribute new disability to old age and to identify demographic , medical , behavioral , and psychosocial characteristics that correlate with attributing new disability to old age . DESIGN Prospect i ve cohort study with 4-year follow-up . SETTING Four geographic regions of the United States . PARTICIPANTS 9704 women aged > or = 67 years participating in the Study of Osteoporotic Fractures . Of these , 657 who reported no disability at baseline but at follow-up reported difficulty carrying out 1 or more of 13 functional activities were eligible for our analysis . MEASUREMENTS All women reporting difficulty in any functional activity at follow-up were asked " What is the main condition that causes you to have difficulty or prevents you from ( doing the activity ) ? " and were shown a card listing 14 medical conditions as well as the option " old age , " from which they could choose only one response . Women attributing difficulty or inability in 1 or more functional activities to old age were classified as attributing new disability to old age . We examined the relationship between attributing new disability to old age and the following characteristics measured at baseline : age , level of education , medical comorbidity , cognitive function , body mass index ( BMI ) , gait speed , grip strength , visual acuity , physical activity level , smoking status , social network level , and depressed mood . RESULTS Overall , 13.5 % of women attributed new disability to old age . Age was a strong independent correlate of attributing new disability to old age : compared with women age 67 to 69 , the odds of attributing new disability to old age for women age 70 to 79 was 3.6 times as large ( 95 % confidence interval [ CI ] = 1.6 - 8.3 ) , and for women age 80 or over was 5.5 times as large ( 95 % CI = 2.1 - 14.7 ) . The only other characteristic that remained an independent correlate of attributing new disability to old age was grip strength ; for each decile decrease in grip strength , a woman 's odds of attributing new disability to old age increased by 9 % ( odds ratio [ OR ] = 1.09 , 95 % CI = 1.01 - 1.19 ) . CONCLUSIONS Despite great advances in geriatric medicine , old age is still perceived as a causal agent in functional decline , especially among our oldest patients . Further study is needed to determine whether , how often , and under what circumstances older adults who attribute new disability to old age have medical conditions amenable to interventions that could preserve their functioning and improve their quality of life
