Abstract
On January 1, 2024, a major earthquake struck Japan's Noto Peninsula. From 2021 to 2023, we conducted a baseline survey. Four months after the disaster, we conducted a follow-up survey to investigate the relationship between house damage and forgetfulness in older adults without dementia. A total of 923 individuals were included. Among the respondents, 32.2% and 33.8% reported as suffered major house damages and increased forgetfulness, respectively. Multivariate analysis revealed major house damage was significantly associated with self-reported forgetfulness, which are partly mediated through sleep disturbance and sedentary behavior in the cognitively unimpaired and mild cognitive impairment groups, respectively.
