ABSTRACT
BACKGROUND:
Walking speed is an important health indicator in older adults, although its measurement can be challenging because of the functional decline due to aging and limited environment. The aim of this study was to examine whether hand grip strength can be a useful proxy for detecting slow walking speed in this population.METHODS:
A cross-sectional study was conducted using the cohort from the Yilan Study in Taiwan. Community-dwelling older adults aged 65 years and older were included. Slow walking speed was defined as a 6-meter walking speed < 1.0 m/s, according to the 2019 Asian Working Group for Sarcopenia diagnostic criteria. Stepwise multiple linear regression was used to determine the most significant variables associated with walking speed. Receiver operating characteristic analysis was used to determine the optimal cutoff values for hand grip strength in detecting slow walking speed.RESULTS:
A total of 301 participants with an average age of 73.9 ± 6.8 years were included; 55.1 % participants were women. In stepwise multiple linear regression analysis that included various variables, hand grip strength was found to be the most explainable factor associated with walking speed among all participants and among participants of each sex. The optimal cutoff values for hand grip strength in the detection of slow walking speed were 19.73 kg for all participants (sensitivity 55 %, specificity 83 %, area under the curve 0.74, accuracy 66.9 %), 35.10 kg for men (sensitivity 92 %, specificity 42 %, area under the curve 0.70, accuracy 66.4 %), and 17.93 kg for women (sensitivity 62 %, specificity 80 %, area under the curve 0.76, accuracy 67.9 %).CONCLUSIONS:
Hand grip strength was found to be a useful proxy for the identification of slow walking speed in older adults.Palavras-chave
