Outline of Final Research Achievements

The findings of this research project indicate that prolonged periods of sedentary behavior are associated with an increased risk of physical and mental health issues among the elderly. Furthermore, it was proposed that prolonged periods of sitting among the elderly may have a detrimental impact on social health, such as interaction with neighbors, which in turn may affect their well-being.
The results of an effectiveness study of an intervention program incorporating behavior change techniques (knowledge provision, goal setting, and self-monitoring) with older adults demonstrated that both the intervention group (intervention focused on sedentary behavior and physical activity) and the control group (intervention focused on physical activity only) exhibited a reduction in sedentary time. However, no statistically significant differences were observed.

Academic Significance and Societal Importance of the Research Achievements

統計学的有意な変化は確認できなかったが、知識提供や目標設定、セルフモニタリングなどの行動変容技法を取り入れた介入プログラムが、座位時間の減少に有効である可能性が示唆されたことは意義がある。また、高齢者のメンタルヘルスに対する長時間の座位行動の悪影響について、座位行動の内容やそれを媒介する要因を含めて明らかにした点は、メンタルヘルスの維持・増進を目指す介入プログラムの作成において貴重な資料を提供する。
