Relationship between Quality of Life and Sociodemographic, Physical and Mental Health Variables in People over 65 in the Community of Madrid

Abstract

Except in the case of depression, there are few studies that analyze mental health variables related to quality of life (QoL) in people over 65 years of age. The objective of this study is to analyze the relationship between QoL and the following variables: sociodemographic and physical and mental health of people over 65 years of age. The sample was randomly selected and consists of men and women between 65 and 84 years of age (N = 555) from the Community of Madrid. Mental disorders were evaluated with the CIDI65+ interview and QoL with the WHOQoL-BREF scale. Means, ANOVA and multiple linear regression analyses were performed. Women have worse QoL than men and QoL worsens with age. The regression model for the dependent variable “WHOQoL BREF Scale” explains 41.43% of the variance (R2 = 0.413). The variables that have the greatest impact on QoL are as follows: a greater number of physical and psychological symptoms, experiencing financial difficulties and the presence of a psychological disorder, while continuing to work has a positive effect on QoL. Physical and mental disorders have a similar impact on QoL. The presence of a greater number of psychological symptoms (without necessarily fulfilling the criteria of a mental disorder) is a predictive variable of worse QoL. Mental health has a burden on the QoL of people over 65 years of age that is as powerful as physical health.
