Does the BODE index reflect the level of physical activity in daily life in patients with COPD?

Abstract

Objectives: To study the relationship between the level of physical activity in daily life and disease severity assessed by the BODE index in patients with chronic obstructive pulmonary disease (COPD). Methods: Sixty-seven patients with COPD (36 men) with forced expiratory volume in the first second (FEV 1 ) of 39 (27-47)% predicted and age of 66 (61-72) years old were evaluated by spirometry, dyspnea levels (measured by the Medical Research Council scale, MRC) and by the 6-minute walking test (6MWT). The BODE index was calculated based on the body mass index (weight/height 2 ), FEV 1 , MRC and 6MWT, and then the patients were divided in four quartiles according to their scores (Quartile I: 0 to 2 points, n=15; Quartile II: 3 to 4 points, n=20; Quartile III: 5 to 6 points, n=23; Quartile IV: 7 to 10 points, n=9 Houve correlação modesta entre os escores do índice BODE e o tempo gasto andando/dia, gasto energético total e tempo gasto/ dia em atividades moderadas e vigorosas (-0,32≤ r ≤-0,47; p≤0.01 para todos). Quando comparados os quartis agrupados I+II com III+IV, houve diferença significante entre o tempo gasto andando/dia, gasto energético total e tempo gasto em atividades moderadas (p≤0,05). Conclusão: O nível de AFVD apresenta correlação modesta com a classificação da gravidade da DPOC dada pelo índice BODE, refletindo apenas diferenças entre pacientes com doença leve-moderada e grave-muito grave.Palavras-chave: DPOC; atividades de vida diária; BODE; TC6.

Handgrip and functional capacity in Chronic Obstructive Pulmonary Disease patients

“…Our results meet the with an increase of mortality and exacerbation rates in patients with COPD (28,29,30).…”

Patients hospitalized for community-acquired pneumonia present reduced functional performance

“…Patients hospitalized for CAP presented lower performance on the 6MWT (66% of predicted), indicating a reduction in FC, as previously demonstrated in patients with stable COPD [22][23][24] . In a study by Solh et al 7 , elderly patients hospitalized for CAP showed a decline in functional capacity as assessed by an ADL scale.…”

Obesity and Physical Activity in the Daily Life of Patients with COPD

“…These authors also concluded that BMI was not a determining factor for PADL level. Other studies also did not find BMI to be a strong correlate of the level of physical activity in daily life in patients with COPD [9,32,33].…”
