O índice BODE correlaciona-se com a qualidade de vida em pacientes com DPOC? Does the BODE index correlate with quality of life in patients with COPD?

OBJETIVO: Determinar se há uma correlação entre o índice Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE; IMC, obstrução das vias aéreas, dispneia e capacidade de exercício) e a qualidade de vida relacionada à saúde em pacientes com DPOC. MÉTODOS: Foram avaliados 42 pacientes com DPOC quanto a parâmetros de função pulmonar; variáveis antropométricas; capacidade de exercício através da distância máxima percorrida no teste de caminhada de seis minutos; dispneia através da escala modificada Medical Research Council (MRC); índice BODE; e a qualidade de vida através do questionário do Saint George's Respiratory Questionnaire modificado (SGRQm). Os pacientes foram alocados em dois grupos de acordo com a estratificação de gravidade da doença: VEF1 > 50% e VEF1 50% e VEF1 OBJECTIVE: To determine whether the Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE) index correlates with health-related quality of life in patients with COPD. METHODS: We evaluated 42 patients with COPD, quantifying the following: lung function parameters; anthropometric variables; exercise capacity, with the six-minute walk test; dyspnea, with the modified Medical Research Council (MRC) scale; the BODE index; and quality of life, with the modified Saint George's Respiratory Questionnaire (mSGRQ). Patients were divided into two groups by disease severity: FEV1 > 50% and FEV1 50% and FEV1 < 50% groups. There was a significant difference between the groups in terms of FEV1 and the FEV1/FVC ratio. There were moderate to significant correlations between the BODE index scores and all of the mSGRQ domains in the group of patients with FEV1 <50%. CONCLUSIONS: The BODE index score correlated with the scores of all of the mSGRQ domains in COPD patients with FEV1 < 50%. Therefore, COPD patients with FEV1 < 50% die sooner and have a poorer quality of life
