Relationship between BODE index and quality of life in COPD patients

Abstract

Malnutrition, weight loss, and peripheral muscle weakness are some of the systemic manifestations of COPD that seriously affect the health related quality of life and exercise capacity of patients (Decramer et al., 2005). The BODE index components are: body mass index (BMI), airway obstruction (O), dyspnea (D) and exercise capacity (E) (Celli et al., 2004). The COPD Assessment Test (CAT) is a quick and easy test to be completed and provides a score that indicates the impact of the disease on the health status of the patients (Gu et al., 2014).The aim of this study was the assessment of the quality of life in COPD patients using CAT and correlating with BODE index. COPD patients in this study were diagnosed and classified into four groups according to GOLD guidelines. BODE index score was calculated according to: BMI, FEV1%pred. post bronchodilator, mMRC and 6MWT (meters) by summing the points that were obtained. CAT questionnaire was used to assess the quality of life. Total CAT score and BODE index score were calculated and data analysed using various statistical tests. In the current study, 60 COPD patients wer
