まとめ
簡易MIND食スクリーナーは、詳細な食物摂取頻度質問票と中程度の相関と一貫性を示し、実践を推定するより迅速な方法を提供する。スコアを過大評価する傾向があるが、
科学分野:
- 神経科学、栄養科学、老年医学
背景:
- MIND食は、地中海食とDASH食を組み合わせたもので、認知機能の健康やアルツハイマー病のリスク低下に関連している。MIND食の実践の評価には、通常、時間のかかる食物摂取頻度質問票(FFQ)が必要である。本研究では、包括的なFFQと比較して、簡易MIND食スクリーナーの妥当性を検証する。
研究 の 目的:
- 15項目のMIND食スクリーナーと詳細なコンピュータ化FFQとの同時妥当性を決定すること。両方の食事評価方法間の信頼性と一致性を評価すること。認知群を区別する上でのスクリーナーの有用性を評価すること。
主な方法:
- インディアナ大学アルツハイマー病研究センターの94名の参加者が、MIND食スクリーナーとVioscreen FFQの両方を完了した。MIND食スコア(0-15)は、両方の尺度で同一の基準を使用して計算された。一致性は、ピアソン相関、級内相関係数(ICC)、および3分位に基づくクロス分類を使用して評価された。
主要な成果:
- MINDスクリーナーはFFQ(平均7.49)よりも高いスコア(平均10.05)を生成し、過大評価の可能性を示唆した。スクリーナーとFFQの間には中程度の相関(r=0.63)と一貫性(ICC=0.64)が見られた。認知正常群と軽度認知障害群の間でMINDスコアに有意差が観察され、調整後もスクリーナーのスコアはわずかに有意であった。
結論:
- MIND食スクリーナーは、MIND食の実践を迅速に推定するための適度な妥当性と一貫性を示す。参加者はFFQと比較してスクリーナーを使用した際に実践を過大評価する傾向がある。スクリーナーは、迅速な食事評価を必要とする研究および臨床現場において、潜在的に価値のあるツールである。

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
