2011年3月11日，日本经历了9.0级地震和随之而来的巨大海啸。这场灾难摧毁了许多沿海城市，造成近2万人伤亡。灾难发生后，许多失去家园的海啸幸存者被迫住在临时的小公寓里。虽然所有海啸幸存者都面临着健康恶化的风险，但老年人不仅在身体健康方面，而且在精神健康方面都面临着特别大的风险。在本研究中，我们进行了一项纵向队列研究，调查和分析了灾后28、32和42个月被迫居住在气仙沼市临时公寓的老年人的健康状况和认知功能。在研究期间，被认为有认知障碍的人的比例显著增加。另一方面，根据24个月和42个月的数据比较，Kessler心理困扰量表-6和Athens失眠量表的平均得分有所提高。多元logistic回归分析显示，“外出活动”频率和“步行时间”与认知障碍人群比例增加独立相关。我们得出结论，居住在临时公寓的老年人认知功能障碍的风险较高，“户外活动”和“步行”可能保持认知功能的稳定性。
On March 11, 2011, Japan experienced an earthquake of magnitude 9.0 and subsequent enormous tsunamis. This disaster destroyed many coastal cities and caused nearly 20,000 casualties. In the aftermath of the disaster, many tsunami survivors who lost their homes were forced to live in small temporary apartments. Although all tsunami survivors were at risk of deteriorating health, the elderly people were particularly at a great risk with regard to not only their physical health but also their mental health. In the present study, we performed a longitudinal cohort study to investigate and analyze health conditions and cognitive functions at 28, 32, and 42 months after the disaster in the elderly people who were forced to reside in temporary apartments in Kesennuma, a city severely damaged by the tsunamis. The ratio of people considered to be cognitively impaired significantly increased during the research period. On the other hand, the mean scores of the Kessler Psychological Distress Scale-6 and Athens Insomnia Scale improved based on the comparison between the data at 24 and 42 months. The multiple logistic regression analysis revealed that frequency of “out-of-home activities” and “walking duration” were independently associated with an increase in the ratio of people with cognitive impairment. We concluded that the elderly people living in temporary apartments were at a high risk of cognitive impairment and “out-of-home activities” and “walking” could possibly maintain the stability of cognitive functions.
