Área de la Ciencia:

  • Ciencia de la Nutrición
  • Neurociencia
  • Salud Pública

Sus antecedentes:

  • El deterioro cognitivo subjetivo (SCD) es una dificultad cognitiva autoinformada que puede indicar demencia temprana.
  • La dieta es un factor modificable para la salud cognitiva, pero la investigación sobre patrones dietéticos y SCD es limitada.
  • Identificar estrategias dietéticas efectivas es crucial para prevenir el deterioro cognitivo.

Objetivo del estudio:

  • Investigar la asociación entre la adherencia a patrones dietéticos saludables específicos y el riesgo de deterioro cognitivo subjetivo (SCD).
  • Evaluar el impacto de la Dieta China de Alimentación Saludable (CHEI), DASH, aMed, hPDI y MIND en el SCD.
  • Proporcionar evidencia para intervenciones dietéticas destinadas a mitigar el deterioro cognitivo.

Principales métodos:

  • El Proyecto de Envejecimiento del Profesorado (TAP) involucró a 3560 profesores chinos (2022-2023).
  • Los patrones dietéticos se evaluaron utilizando un cuestionario de frecuencia de alimentos (FFQ) simplificado.
  • La regresión logística multinomial analizó las asociaciones entre la adherencia a patrones dietéticos (terciles) y el SCD, ajustando por covariables.

Principales resultados:

  • Una mayor adherencia a las dietas DASH, AMED y MIND se asoció significativamente con un menor riesgo de SCD severo (ORs que varían de 0.70 a 0.64).
  • La dieta MIND mostró una fuerte asociación significativa con un menor riesgo de SCD severo (OR=0.64 en el Modelo 1, OR=0.72 en el Modelo 3).
  • Las asociaciones con SCD moderado fueron generalmente más débiles y no estadísticamente significativas.

Conclusiones:

  • La adherencia a los patrones dietéticos DASH, AMED y MIND se asocia con un menor riesgo de deterioro cognitivo subjetivo severo.
  • Estos hallazgos sugieren que la adopción de patrones dietéticos más saludables puede ser una estrategia viable para reducir el riesgo de deterioro cognitivo.
  • Investigaciones futuras pueden explorar componentes alimenticios específicos y los mecanismos subyacentes a estas asociaciones.
