OBJECTIVES To reveal self-rated changes of health status during stay-at-home orders among older adults and to verify whether decrease in frequency of going outdoors during these orders was related to self-rated changes in health status. METHOD A self-completed questionnaire for older adults was provided in 2 dayservice facilities and a nursing station. We operationally defined health status with 4 domains (motor function, oral and swallowing function, depression, and social networks) and designed the questionnaire to determine self-rated changes in health status using factor analysis. After factor analysis, regression analyses were conducted. Dependent variable was each factor score (self-rated changes of health status), and independent variable was decrease in frequency of going outdoors. RESULTS Approximately 80% of participants answered that their health status had "worsened" in motor function (75.0%-87.2%). Moreover, more than 70% of participants answered "worsened" in "Feeling energy" and "Getting together and speaking with friends" (72.3% and 75.7%, respectively). Regression analyses demonstrated that, after adjusting for covariates, the decrease in frequency of going outdoors was related to self-rated changes of motor function and friend network. CONCLUSION During stay-at-home orders, older adults felt deterioration in their motor function, in feeling energy, and in their friend network, especially people who had decreased their frequency of going outdoors felt more deterioration in their motor function and in their friend network.
