Outline of Research at the Start

高齢期の転居は重大なストレス因であるが、転居後の高齢者が実際にどのような精神的健康の変化を経験するのか十分に明らかでない。本研究では転居ストレスの大きさが異なる災害時と平時の転居に関して、それぞれに共通または特異的な高齢転居者の精神的健康面での環境適応過程を明らかにし、介入すべき住まいの環境要因を特定する。具体的にはまず、地域在住高齢者が転居後に経験する精神的健康の変化の軌跡を明らかにする。次に、精神的健康の回復などの良好な軌跡パターンと関連する住まいの環境要因(住宅・近隣環境・近隣の人との社会関係)を明らかにする。

Outline of Final Research Achievements

Compared to non-movers immediately after the disaster, older adults who moved to temporary housing had 3.8 times the risk of depression about 6 months after the disaster, but this risk was reduced by about 40% for those who changed their group participation status. On the other hand, when followed up to about 3.5 years after the disaster, those who moved to temporary housing tended to have a higher risk of chronic depression and PTSD symptoms, while those who moved to non-temporary housing such as deemed temporary housing or rental housing had a higher risk of delayed onset of PTSD symptoms as well as the risk of chronic depression and PTSD symptoms. For ordinary-time relocation, those who were dissatisfied with their home at a time of fewer than five years after relocation had a higher risk of depression compared to long-term residents who were satisfied with their home. Home environmental factors related to home dissatisfaction were housing facilities and rent/maintenance costs.

Academic Significance and Societal Importance of the Research Achievements

本研究により、震災による転居に関しては、高齢転居者が仮設住宅で従来のグループ活動への関わり方を変化させるなど、つながりを最適化することで短期的には転居ストレスが軽減される可能性が示された。一方で、震災約3年半後まで観察したところ、高齢転居者はうつ・PTSD症状の慢性化やPTSD症状の遅発を経験するリスクが高い傾向にあることから、中長期にわたる転居者の精神的ケアの必要性も示唆された。平時の転居については、住まいに不満がある場合のみ、転居者のうつリスクが高いことが示された。住宅設備の充足や経済問題の解消などが精神的健康の悪化予防に重要と考えられる。
