  • Descrição: We previously established that housing loss and residential dislocation in the 2011 Japan earthquake and tsunami was a risk factor for cognitive decline among older survivors. The present study extends the follow-up of survivors out to 6 years. The baseline for our natural experiment was established in a survey of older community-dwelling adults who lived 80 km west of the epicenter 7 months before the earthquake and tsunami. Two follow-up surveys were conducted approximately 2.5 years and 5.5 years after the disaster to ascertain the housing status and cognitive decline from 2810 older individuals (follow-up rate through three surveys: 68.4%). The experience of housing loss was persistently associated with cognitive disability (coefficient = 0.14, 95% confidence interval: 0.04 to 0.23). Experiences of housing loss continued to be significantly associated with cognitive disability even six years after the disaster. •Experiences of housing loss were persistently associated with cognitive disability.•Decreased social interaction partially mediated those associations.•Promoting civic participation may be effective to improve cognitive resilience.
