Abstract

El presente trabajo se centra en el estudio del tiempo hasta la discapacitación para las actividades de la vida diaria en la población activa de Cataluña mayor de 60 años. El riesgo de sufrir discapacidades es mayor para este grupo de edad que en los más jóvenes y, además, se incrementa con la edad. La aparición de discapacidades resta habilidades a la hora de realizar las distintas actividades de la vida diaria, por ello hemos centrado nuestro interés en la variable tiempo hasta que una persona de 60 años que no muestra discapacidad alguna, se discapacita, identificando factores ligados a los incrementos del riesgo de discapacitación. A partir de los datos que proporciona la Encuesta sobre Discapacidades, Deficiencias y Estado de Salud (EDDES, INE 1999) y, utilizando el estimador de Kaplan-Meier, se estiman las funciones de supervivencia que permiten calcular probabilidades relacionadas con la edad de discapacitación. Asimismo, se ha realizado un análisis del modelo de regresión de Weibull que permite interpretar cómo y en qué medida afectan las características individuales. = In Spain individuals aged 60 years and above are major consumers of the health care system. The risk of becoming unable to perform daily life activities is higher for the elderly than for the younger population, and in addition, it increases with age. As a consequence we focus on the study of the period of life after an abled person who is 60 years old becomes disabled and we also study the factors that are related to the risk of disability. Using data from the Survey of Disabilities, Handicaps and Health Status (EDDES, INE 1999), and using the Kaplan-Meier estimator, we estimate the survival functions to calculate the probability of becoming disabled at different age points. Besides, a Weibull regression model is estimated in order to interpret the effects of individual characteristics on the disability risk.
