Resumen
Introducción: con el aumento en la esperanza de vida las condiciones relacionadas con mayor edad incrementaron su incidencia; una de estas patologías es el deterioro cognitivo (DC) que presenta una prevalencia de hasta el 28%, hoy en día se conocen condiciones que aumentan la presencia de DC. Sin embargo, existe controversia sobre los factores que aumentan el riesgo para su presencia.
Objetivo: determinar los factores asociados al deterioro cognitivo en adultos mayores.
Material y métodos: se realizó un estudio transversal, analítico, observacional, retroprolectivo que incluyó a adultos ≥ 65 años, sin antecedente de evento vascular cerebral o traumatismo craneoencefálico. Se analizaron factores demográficos, el DC se evaluó con la prueba Mini-Mental.
Resultados: se incluyeron 420 adultos mayores, de los cuales el 61% eran mujeres, el 32.6% tenían edad > 75 años, el 84.5% con escolarización < 9 años. En la regresión logística múltiple los siguientes fueron factores independientes para la presencia de DC leve: la dependencia de actividades básicas de la vida diaria (ABVD), ausencia de estimulación cognitiva, edad > 75 años, polifarmacia y descontrol de tensión arterial.
Conclusión: la dependencia de ABVD, ausencia de estimulación cognitiva, edad > 75 años, polifarmacia y descontrol de la tensión arterial son factores de riesgo asociados al DC en adultos mayores.
Abstract
Background: With the increase in life expectancy, conditions related to older age have increased in incidence, one of these pathologies is Cognitive Impairment (CI), which has a prevalence of up to 28%, conditions that increase the presence of CI are known. However, there is controversy about the factors that increase the risk of CI.
Objective: To determine the factors associated with cognitive impairment in older adults.
Material and methods: We conducted a cross-sectional, analytical, observational, retroprolective study that included adults ≥65 years of age, with no history of cerebral vascular event, cranioencephalic trauma. Demographic factors were analyzed, CI was assessed with the Mini Mental State Examination test.
Results: 420 older adults were included, 61% were women, 32.6% with age >75 years, 84.5% with schooling <9 years, in the multiple logistic regression the following were independent factors for the presence of mild CI: dependence on basic activities of daily living (ADLs) with OR 5.88, absence of cognitive stimulation RM 4.50, age >75 years OR 2.92, polypharmacy OR 2.16, uncontrolled blood pressure OR 1.92.
Conclusion: ADLs dependence, absence of cognitive stimulation, age >75 years, polypharmacy and uncontrolled blood pressure are risk factors associated with CI in older adults.
