Structural equation modeling of the relationships between lifestyles and related health factors of the community-dwelling elderly

摘要

[Purpose] This study investigated the relationships among lifestyles, functional capacity and motor ability using structural equation modeling (SEM). [Subjects] The participants were 211 elderly persons (average age: 76.4 ± 8.6 years) living in K Prefecture. [Methods] The survey was conducted by interviews and motor ability test. There were 22 items for lifestyles, 13 items for functional capacity and 3 items for physical performance in the survey. In the SEM analysis, we employed a multiple basic model. [Results] The root mean square error of approximation (RMSEA) of the inal model was 0.09 and the Akaike information criterion (AIC) was 59.4 in the peripheral models. The degree of association between lifestyles and motor ability, and functional capacity was 0.99. [Conclusion] This study deined a pilot model for factors inluencing lifestyles. Although it remains necessary to conducts further analyses with more valid measurements and constructs.
