Abstract
Introduction: In the elderly, the decline in Instrumental Activities of Daily Living (IADL), is related to cognitive impairment; however, not all of them are affected, particularly during the early in the disease. Therefore, identifying these associated IADL could help achieve earlier and more accurate diagnoses.
Objective: Identifying which IADL are more associated with cognitive impairment in older adults.
Materials and methods: Data from SABE Bogota Study (2012) was used, where 2000 older adults (?60 years) were interviewed in a cross sectional study, collecting a probabilistic cluster sample, with a coverage of 81.9%. To collect the data were used: the modified instrument Minimental (MMSE-M) and 13 instrumental activities of daily living. Bivariate analyzes were performed and multivariate logistic regression models to find statistically significant associations (p <0.05).
Results: The AIVD with the highest association were: not able to “use the phone” OR 5.007 (95% CI 3.01-8.32), “manage their own money” OR 2.58 (95% CI 1.57-4.23), “prepare your own food alone” OR 1.83 (95% CI 1.11-3.02), “taking their own medicine” OR 1.83 (95% CI 1.06-3.02), and doing “heavy labor at home such as washing the floor or walls” OR 1.696 (CI 1.075-2.75 ).
Conclusion:Instrumental activities of daily life living associated with cognitive decline were those that required greater capacity for abstraction and planning. This information can be useful to the clinician during interrogation in order to maximize their time in the medical consult, detecting cognitive impairment and indicating an appropriate diagnostic and early treatment.
