Classification and comparison of the physical characteristics and functions of various age groups of community-dwelling elderly individuals participating in the Kayoi-no-ba program

Abstract

[Purpose] To classify and compare the physical characteristics and functions of community-dwelling elderly individuals of various age groups participating in the Kayoi-no-ba program. [Participants and Methods] A total of 176 community-dwelling elderly individuals living in six cities and towns in the Niigata Prefecture who participated in the Kayoi-no-ba program between 2018 and 2020 were recruited in this study. Physical characteristics, such as strength, balance, and mobility, were assessed. [Results] Among elderly females and males who participated in the Kayoi-no-ba program, those >80 years of age showed shorter height, lighter weight, and lower body muscle mass than the other age groups. Strength, balance, and mobility functions, including grip strength, sit-to-stand test, single-leg-stand test, and timed up-and-go test, were significantly decreased, especially in patients aged >80 years. [Conclusion] Among community-dwelling elderly individuals participating in the Kayoi-no-ba program, physical characteristics and functions were affected by aging, with significant decline particularly in those aged >80 years old. These findings suggest that early intervention is necessary to maintain muscle mass, strength, balance, and mobility in the elderly.
