Abstract
INTRODUCTION
Higher adherence to the Mediterranean-DASH (Dietary Approaches to Stop Hypertension) Intervention for Neurodegenerative Delay (MIND) diet has been associated with reduced Alzheimer's disease (AD) risk. This study assessed the validity of a brief 15-item MIND diet screener compared to a comprehensive food frequency questionnaire (FFQ).
METHODS
The validity of an adapted MIND diet screener relative to the VioScreen FFQ was evaluated in 92 older adults from the Indiana Alzheimer's Disease Research Center (IADRC). Correlation coefficients and tertile-based classification statistics were used, and FFQ nutrient profiles were examined across screener-based MIND diet tertiles.
RESULTS
MIND diet scores from the screener showed strong positive correlation (r = 0.71, ρ = 0.70, p < 0.001) and comparable ranking ability (63% correctly classified, 1% grossly misclassified, kw = 0.67) compared to those from the FFQ, as well as significant associations with nutrient profiles.
CONCLUSION
The MIND diet screener is an acceptable, time-efficient tool for estimating MIND diet scores in older adults.
Highlights
The MIND diet screener effectively differentiated participants by diet quality.
Agreement between instrument scores was consistent across diagnostic groups.
Reliability of the screener over approximately 1 year was comparable to the FFQ.
The MIND diet screener is an acceptable tool for use in time-constrained settings.
Future studies should confirm validity using objective biomarkers.
期刊介绍：
Alzheimer's & Dementia is a peer-reviewed journal that aims to bridge knowledge gaps in dementia research by covering the entire spectrum, from basic science to clinical trials to social and behavioral investigations. It provides a platform for rapid communication of new findings and ideas, optimal translation of research into practical applications, increasing knowledge across diverse disciplines for early detection, diagnosis, and intervention, and identifying promising new research directions. In July 2008, Alzheimer's & Dementia was accepted for indexing by MEDLINE, recognizing its scientific merit and contribution to Alzheimer's research.
