Resumen
La longevidad materna se asocia con una mejor función cognitiva de la descendencia, especialmente en México. Una mayor educación de la descendencia explica parcialmente esta asociación, lo que sugiere una compleja interacción de factores.
Área de la Ciencia:
- Gerontología; Ciencias Cognitivas; Salud Pública
Sus antecedentes:
- La longevidad parental se asocia con mejores resultados cognitivos en la descendencia.; Existe una investigación limitada sobre este vínculo en países de ingresos bajos y medianos.; Se deben investigar los posibles mecanismos económicos y de salud.
Objetivo del estudio:
- Examinar la asociación entre la longevidad parental y la capacidad cognitiva de la descendencia en México.; Explorar los mecanismos económicos, de salud y conductuales subyacentes.
Principales métodos:
- Se utilizaron datos del Estudio Mexicano de Salud y Envejecimiento (MHAS) de 2018.; Se analizó la longevidad parental autoinformada (fallecidos antes o después de los 80 años).; Se empleó regresión lineal, ajustando por confusores y mediadores potenciales.
Principales resultados:
- La longevidad materna se correlacionó con una mayor capacidad cognitiva general y un mejor rendimiento en múltiples tareas cognitivas.; La longevidad paterna no mostró una asociación significativa con la cognición de la descendencia.; La educación explicó parcialmente la asociación entre la longevidad materna y la cognición; los factores de salud/conductuales no lo hicieron.
Conclusiones:
- La longevidad materna, no la paterna, se asocia positivamente con la capacidad cognitiva de la descendencia.; Una mayor educación de la descendencia puede explicar parcialmente los beneficios cognitivos de tener una madre longeva.; La genética y el apoyo familiar también podrían contribuir a las ventajas cognitivas.
