Outline of Final Research Achievements

The results of a study of factors contributing to the progression of brain aging manifested as pre-frail/frail and cognitive decline in older adults showed that among community-dwelling older adults, those who showed temporary improvement after physical and mental/psychological frailty were less likely to require new nursing care in the following years. In addition, although family structure, length of residence, and social participation may be associated with factors leading to a transition to long-term care status, the associations differed depending on whether the cognitive decline was possible. Furthermore, in the frail high-risk population with diabetes, a lifestyle-related disease, many suspected mild cognitive decline, indicating that glycemic control status is related to frailty and death.

Academic Significance and Societal Importance of the Research Achievements

一度身体的フレイル状態及び精神・心理的フレイル状態になっても、一時的に改善を認める者は、その後の新規要介護状態を回避することができていることが考えられ、フレイル状態での介入強化の必要性を示した。後期高齢者へのフレイル健診への受診勧奨の根拠しても用いることが可能です。
