Objective: The aims of this study were to examine the preparedness of vulnerable people ages 75 years and older and to clarify the characteristics of older adults that are associated with disaster preparedness.
Methods: We conducted interviews with persons requiring special care ages 75 years and older living in coastal communities of western Japan, where earthquakes and tsunami disasters are a concern. The survey included participant characteristics such as demographic indicators, physical function, health status, community involvement, and disaster preparedness. Binomial logistic regression analysis was performed with participant characteristics as independent variables and disaster preparedness as the dependent variables.
Results: The characteristics related to disaster preparedness were age, family composition, cognitive function, level of interaction with neighbors, and participation in community activities.
Conclusions: Being female, living alone, and having cognitive impairment were factors that led to decreased disaster preparedness. However, it was suggested that close human interactions in the community facilitated preparedness. Community engagement is crucial in reducing disaster damage and recovering effectively. In order to facilitate preparedness measures for persons requiring special care ages 75 and older, it is important to establish community preparedness.
