Abstract: Objective To evaluate the physical functions of community-dwelling older adults, and analyze the related factors. Methods From September to October, 2016, 80 adults over 55-year-old in one community in Wuhan, Hubei, China were selected with convenience sampling. General situation was collected through questionnaires. Physical functions were measured by tests of grip strength, Five-Times-Sit-to-Stand Test (FTSST), modified Clinical Test of Sensory Interaction and Balance (mCTSIB) and Timed "Up and Go" Test (TUGT). Their correlation was analyzed. Results The average grip strength of the participants was (27.46±9.66) kg; the average time of FTSST was (11.58±4.03) s; there was only one (1.25%) participant observed with an impairment in mCTSIB; the average time of TUGT was (9.05±3.47) s. Grip strength was correlated with gender (r=-0.669), education level (r=0.238), the score of Mini-Mental State Examination (MMSE) (r=-0.302) and activities of daily living (ADL) (r=-0.344) (P<0.05). The time of FTSST was correlated to gender (r=0.274), the score of MMSE (r=0.243) and ADL (r=0.321) (P<0.05). The time of TUGT was correlated to gender (r=0.255), education level (r=-0.362), income level (r=-0.245), the score of Self-rating Depression Scale (r=0.223), the score of MMSE (r=0.328) and ADL (r=0.354) (P<0.05). Conclusion The levels of grip strength, FTSST and TUGT are related to the demographic characters in community-dwelling older adults. Little abnormity has been found in mCTSIB.
