Subsequent Falls and Disability in Older Persons Performance on Five Times Sit-to-Stand Task as a Predictor of

Objectives: To investigate whether the performance on 5 times sit-to-stand test (5tSTS) can predict subsequent falls, fall-related fracture, and activities of daily living (ADL) and instrumental activities of daily living (IADL) disability in older persons. Methods: A total of 948 older adults (age ≥ 60) participated in this study. Ability and the time to finish 5tSTS were recorded at baseline. Number of falls, fall-related fractures, and the ability to complete ADL and IADL without assistance were recorded retrospectively at baseline and at the 3-year follow-up. Results: Inability to complete 5tSTS was a marginal predictor of falls (OR = 4.22) and a significant predictor of ADL(OR = 24.70) and IADL-related disability (OR = 17.10) at 3-year follow-up. The need of at Univ of Connecticut / Health Center / Library on February 19, 2013 jah.sagepub.com Downloaded from 2 Journal of Aging and Health XX(X) longer time to complete 5tSTS was predictive of developing IADL-related disability at 3-year follow-up (OR = 4.22 [> 16.6 s]; OR = 2.49 [13.7 – 16.6 s]). Discussion: 5tSTS is an easily administered tool which can be used to predict subsequent ADLand IADL-related disability.
