Caracterização da qualidade de vida de indivíduos com DPOC e sua associação com variáveis sociodemográficas e clínicas

Abstract

Chronic obstructive pulmonary disease (COPD) is a complex condition, with many components that contribute to its pathophysiology and presentation, negatively reflecting the quality of life (QOL) and functionality of the lung disease individual. The objective was to identify clinical and sociodemographic characteristics related to QOL in individuals with COPD. Cross-sectional study that addresses 100 individuals with COPD. Sociodemographic, clinical and functional data were collected from the participant's medical records using the COPD Assessment Test (CAT), St. George Respiratory Questionnaire (SGRQ) instruments after descriptive analysis, univariate and multivariate association testing, including exposure 2 variables and the three different domains of the SGRQ, as well as their overall score. The overall perception of QOL is better in individuals with higher educational level (p <0.03) and lower impact of COPD symptoms as measured by CAT (p <0.0001). In multivariate analysis, sociodemographic variables, as well as the classification of COPD according to GOLD and CAT score, compromised the perception of QoL measured by the SGRQ in at least one of your domains. The QOL of individuals with COPD seem to be associated with sociodemographic aspects, as well as objective measures indicative of pulmonary function impairment.
