    摘要: Background: Older adults who are dependent in instrumental activity of daily living (IADL) are more likely to develop activity of daily living (ADL) disability later. Therefore, for health promotion or disability prevention programs to be effective, the health care providers need to be able to identify older adults at early stage of physical functioning decline. Physical performance tests could reflect older adults at different hierarchical disability status. Grip strength and gait speed are indicators of frailty and predictors of many adverse health outcomes in older adults such as future disablement, falls, mortality etc. Purpose: the purpose of this study was to report the cutoff value of grip strength and usual gait speed to separate older adults at different hierarchical disability groups (IADL and ADL both abled, IADL disabled only, IADL and ADL both disabled) separately for sex (men and women) and age ( 65-74 years and ≧ 75 years) subgroups. Method: 2,565 subjects aged 65 and over were recruited from Sarcopenia and Translational Aging Research in Taiwan (START) including several studies from north, middle, and south part of Taiwan. The inclusion criteria were aged 65 years or older, lived in community. The exclusion criteria were had history of stroke. Their demographic information (age, sex, education, living alone or not) and health related information (comorbidity, body mass index) were collected and their grip strength (kg) and usual gait speed (m/s) were measured.Results: The demographic and health related variables of our participants in three disability groups were reported in Table 1. The optimal and 90% specificity cutoff values to separate the all able group from the IADL disabled group and to separate the IADL disabled group and both disabled group were reported for each age-sex subgroups, adjusted for age, number of comorbidity, and level of education, for grip strength (table 2) and usual gait speed (table 3). Conclusion: The reported optimal cutoff value serves as a benchmark for grip strength and gait speed in order for clinicians to be able to better explain the test results and older adults’ functional status. The 90% specificity cutoff value could be used to “rule in” those who need to be closely followed or further detailed tests.
