Resumen
Un breve cuestionario de la dieta MIND muestra una correlación y consistencia moderadas con un cuestionario detallado de frecuencia de alimentos, ofreciendo una forma más rápida de estimar la adherencia. Aunque sobreestima las puntuaciones,
Área de la Ciencia:
- Neurociencia
- Ciencia Nutricional
- Gerontología
Sus antecedentes:
- La dieta MIND, un híbrido de las dietas mediterránea y DASH, se asocia con la salud cognitiva y la reducción del riesgo de Alzheimer.
- La evaluación de la adherencia a la dieta MIND generalmente implica largos cuestionarios de frecuencia de alimentos (CFF).
- Este estudio valida un breve cuestionario de la dieta MIND frente a un CFF completo.
Objetivo del estudio:
- Determinar la validez concurrente de un cuestionario de la dieta MIND de 15 ítems en comparación con un CFF computarizado detallado.
- Evaluar la fiabilidad y el acuerdo entre los dos métodos de evaluación dietética.
- Evaluar la utilidad del cuestionario para distinguir entre grupos cognitivos.
Principales métodos:
- 94 participantes del Centro de Investigación de la Enfermedad de Alzheimer de Indiana completaron tanto el cuestionario de la dieta MIND como el CFF Vioscreen.
- Se calcularon las puntuaciones de la dieta MIND (0-15) utilizando criterios idénticos para ambos instrumentos.
- Se evaluó el acuerdo utilizando la correlación de Pearson, los coeficientes de correlación intraclase (ICC) y la clasificación cruzada basada en tercios.
Principales resultados:
- El cuestionario de la dieta MIND arrojó puntuaciones más altas (media 10,05) que el CFF (media 7,49), lo que indica una posible sobreestimación.
- Se encontró una correlación moderada (r=0,63) y consistencia (ICC=0,64) entre el cuestionario y el CFF.
- Se observaron diferencias significativas en las puntuaciones de la dieta MIND entre los grupos cognitivamente normales y con deterioro cognitivo leve, y la puntuación del cuestionario se mantuvo marginalmente significativa después de los ajustes.
Conclusiones:
- El cuestionario de la dieta MIND demuestra una validez y consistencia moderadas para la estimación rápida de la adherencia a la dieta MIND.
- Los participantes tienden a sobreestimar su adherencia cuando utilizan el cuestionario en comparación con los CFF.
- El cuestionario es una herramienta potencialmente valiosa para la investigación y los entornos clínicos que requieren evaluaciones dietéticas rápidas.

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.
