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.
我们之前的研究表明,2011 年日本地震和海啸中的住房损失和居民流离失所有可能成为老年幸存者认知能力下降的一个风险因素。本研究将幸存者的随访时间延长至 6 年。
我们的自然实验以地震和海啸发生前 7 个月居住在震中以西 80 公里的社区中年龄较大的成年人的一项调查为基础。在灾难发生大约 2.5 年和 5.5 年后进行了两次后续调查,以确定 2810 名老年人的住房状况和认知能力下降情况(通过三次调查的随访率:68.4%)。
住房损失的经历与认知障碍持续相关(系数=0.14,95%置信区间:0.04 至 0.23)。
即使在灾难发生六年后,住房损失的经历仍与认知障碍显著相关。
