Abstract:
Objective:To construct and validate the physical fitness age model for community-dwelling elderly people, so as to provide new methods and reference for the health assessment and rehabilitation guidance of the elderly.Methods:From March to September 2021, 794 community-dwelling health people in six districts of Suzhou (Wuzhong District, Gusu District, Xiangcheng District, Wujiang District, Huqiu District and Industrial Park) were selected by multi-stage stratified sampling. Postgraduates who received unified training used unified monitoring tools to assess the physical function and physical fitness of the subjects in the designated community health service centers. Principal component analysis was used to construct a physical fitness age model. According to the scores of Short Physical Performance Battery, people with high physical function and people with low physical function were divided to verify the effectiveness of the model evaluation.Results:A total of four indicators, including 2-min step test, 30 s chair stand test, biceps flexion and lift test, and time up and go test (TUGT) , were finally included to build a physical fitness age model. The model formula was physical fitness age=-0.126×2-min step test-0.612×biceps flexion and lift test-0.625×30 s chair stand test+1.855×TUGT+0.51×age+55.29. The model validation showed that the physical fitness age of the community-dwelling elderly people of the high physical function group was lower than the age, and the difference was statistically significant ( P<0.01) . The physical fitness age of the community-dwelling elderly people of the low physical function group was higher than that of the age, and the difference was also statistically significant ( P<0.01) . The research results were consistent with the research assumptions, suggesting that the model was reasonable and effective. Conclusions:The construction of the physical fitness age model for community-dwelling elderly people can reflect the decline of the elderly's physical function, can be used for the elderly's health assessment and rehabilitation guidance, and can provide evaluation indicators for the elderly to provide community and home medical care services.
