地域在住女性高齢者の献立立案から取り組む集団調理プログラムの効果

Effects of a collective cooking intervention program focusing on mission planning in community-dwelling elderly females

要旨：本研究の目的は，献立立案から取り組む集団調理プログラムが，地域在住女性高齢者の認知機能と自宅での調理頻度に及ぼす効果を調査することであった．対象は地域在住女性高齢者39名で，献立立案-調理群20名，調理実施群19名に週1度・6ヵ月間集団調理プログラムを実施し，介入前後で認知機能，心理機能，社会的活動量の変化を比較検討した．結果，認知機能項目で測定時期による主効果を認めたが，交互作用はなかった．また，調理頻度の変化も両群で有意差は示されなかった．今回の結果から，調理活動自体の認知機能改善への効果は示唆されたが，献立立案課題単独の認知機能・調理頻度への効果は乏しく，介入手法についてさらなる検討が必要である．

　This study investigated the effects of a collective cooking intervention focusing on mission planning on the cognitive function and frequency of cooking at home among community-dwelling elderly females. This study involved 39 elderly female residents living in the community. The residents were divided into a mission planning-cooking group (20 participants) and a cooking group (19 participants). Each program was held once a week for 6 months, and the cognitive function, psychological function, and social behavior of the participants were evaluated before and after the intervention. Results revealed that although the main effect was recognized in the cognitive functions, no interaction and no difference resulting from changing the frequency of cooking were observed between the two groups. These results suggest that although cooking intervention can improve cognitive function, its effect on cognitive function and cooking frequency is not clear. Therefore, this intervention strategy is in need of further consideration.
