Associação entre a qualidade de vida avaliada pelo WHOQOL-BREF e desfechos de saúde física na DPOC

Abstract

COPD is a heterogeneous and complex disease, its symptoms cause limitations that significantly compromise the health-related quality of life (HRQoL) of patients. The abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) is a generic questionnaire with 26 questions that presents a good psychometric performance, in addition to its practical application. Objective: To investigate the association between health-related quality of life assessed by the shortened version of the WHOQOL questionnaire and physical and mental outcomes in patients with COPD. Method: This is an observational cross-sectional study, in which individuals with COPD were assessed for their HRQoL using WHOQOL-BREF, in addition, lung function, health status, functional capacity, limitations on ADLs, mobility were also evaluated. functional capacity and exercise capacity through physical tests.Results: It was observed that the WHOQOL-bref and its domains have a moderate to excellent relationship with health status outcomes, limitations in ADL and functional mobility, and no correlation with outcomes pulmonary function, functional capacity and exercise. Conclusion: The association of WHOQOL-bref and its domains may have a likely good to excellent relationship with outcomes health status, limitations in ADLs and functional mobility, however, a larger sample and the development of new studies are necessary.
