Effects of lifestyle on the health, depression, and quality of life of middle‐aged and elderly before and after COVID‐19: Structural equation modeling

Background The purpose of this study is to identify the effects of the lifestyle (physical activity, activity participation, and nutrition) of middle‐aged and elderly people on health, depression, and quality of life, and to identify changes before and after COVID‐19. In addition, it is intended to establish a structural equation model to confirm the influence coefficients for each path. Method Among those aged 55 and older, the study measured lifestyle, subjective health, depression, and quality of life for a total of 327 people. We used SPSS 25 for general characteristics of subjects, descriptive statistical analysis of variables, and AMOS 20 for validation of variables, affirmative factor analysis, and effectiveness analysis on paths. Result In the case of physical activity, there were significant differences between the two groups in moderate exercise (p
