Área de la Ciencia:

  • Gerontología
  • Neurociencia
  • Salud Pública

Sus antecedentes:

  • Fumar es un factor de riesgo conocido para el deterioro cognitivo.
  • La relación precisa entre fumar y el deterioro cognitivo requiere una mayor investigación.

Objetivo del estudio:

  • Examinar la asociación entre el estado de fumador y el deterioro cognitivo en una cohorte rural de Xi'an.
  • Investigar la influencia de la edad en esta relación.

Principales métodos:

  • Se estudió una cohorte de individuos de mediana edad y ancianos cognitivamente normales en la zona rural de Xi'an.
  • Los participantes se clasificaron en fumadores, exfumadores y no fumadores según los datos de la encuesta de 2018.
  • La función cognitiva se evaluó utilizando el Mini-Mental State Examination (MMSE), definiéndose el deterioro cognitivo como un ΔMMSE de ≥2 entre 2014 y 2018.

Principales resultados:

  • El estudio incluyó 1289 participantes: 910 no fumadores, 335 fumadores y 44 exfumadores.
  • En general, no se observó una diferencia significativa en la incidencia de deterioro cognitivo entre los grupos de fumadores (p=0,880).
  • Sin embargo, en personas de 65 años o más, el análisis ajustado reveló un riesgo significativamente mayor de deterioro cognitivo para los fumadores en comparación con los no fumadores (OR=14,139, p=0,019).

Conclusiones:

  • Fumar se asocia positivamente con el deterioro cognitivo en la población de ancianos.
  • Los hallazgos sugieren que fumar puede acelerar el deterioro cognitivo en adultos mayores.
