Perfil do nível de atividade física na vida diária de pacientes portadores de DPOC no Brasil

Abstract

Objective: To evaluate characteristics of physical activities in daily life in COPD patients in Brazil, correlating those characteristics with physiological variables. Methods: Physical activities in daily life were evaluated in 40 COPD patients (18 males; 66 ± 8 years of age; FEV 1 = 46 ± 16 % of predicted; body mass index = 27 ± 6 kg/m 2 ) and 30 healthy age-and gender-matched subjects, using a multiaxial accelerometer-based sensor for 12 h/day on two consecutive days. We also assessed maximal and functional exercise capacity, using the incremental exercise test and the six-minute walk test (6MWT), respectively; MIP and MEP; peripheral muscle force, using the one-repetition maximum test and the handgrip test; quality of life, using the Saint George's Respiratory Questionnaire (SGRQ); functional status, using the London Chest Activity of Daily Living questionnaire; and dyspnea sensation, using the Medical Research Council (MRC) scale. Results: Mean walking time/day was shorter for COPD patients than for the controls (55 ± 33 vs. 80 ± 28 min/day; p = 0.001), as movement intensity was lower (1.9 ± 0.4 vs. 2.3 ± 0.6 m/s 2 ; p = 0.004). The COPD patients also tended to spend more time seated (294 ± 114 vs. 246 ± 122 min/day, p = 0.08).Walking time/day correlated with the 6MWT (r = 0.42; p = 0.007) and maximal workload (r = 0.41; p = 0.009), as well as with age, MRC scale score and SGRQ activity domain score (−0.31 ≤ r ≤ −0.43; p ≤ 0.05 for all). Conclusions: This sample of Brazilian patients with COPD, although more active than those evaluated in studies conducted in Europe, were less active than were the controls. Walking time/day correlated only moderately with maximal and functional exercise capacity.Keywords: Pulmonary disease, chronic obstructive; Motor activity; Exercise tolerance. ResumoObjetivo: Avaliar as características de atividades físicas na vida diária de pacientes portadores de DPOC no Brasil e sua relação com diferentes variáveis fisiológicas. Métodos: Foram avaliados 40 pacientes portadores de DPOC (18 homens; 66 ± 8 anos; VEF 1 = 46 ± 16 % predito; índice de massa corpórea = 27 ± 6 kg/m 2 ) e 30 idosos saudáveis pareados por gênero e idade quanto às atividades físicas na vida diária, utilizando-se um acelerômetro multiaxial por 12 h/dia durante dois dias consecutivos. Foram ainda avaliados as capacidades máxima e funcional de exercício através do teste incremental máximo e do teste de caminhada de seis minutos (TC6), respectivamente; PImáx e PEmáx; força muscular periférica através dos testes de uma repetição máxima e de força de preensão manual; qualidade de vida através de Saint George's Respiratory Questionnaire (SGRQ); estado funcional através do questionário London Chest Activity of Daily Living; e sensação de dispneia através da escala do Medical Research Council (MRC). Resultados: Os pacientes portadores de DPOC apresentaram menor tempo de caminhada/ dia quando comparados aos idosos saudáveis (55 ± 33 vs. 80 ± 28 min/dia; p = 0,001) e menor intensidade de movimento (1,9 ± 0,4 vs. 2,...

O índice BODE correlaciona-se com a qualidade de vida em pacientes com DPOC?

“…(18) An interesting finding in our study was that related to exercise capacity: the mean 6MWD in our COPD patients (> 400 m) was greater than that observed in COPD patients evaluated in a study conducted in Europe, in which the mean 6MWD was < 400 m. (19) This can be explained, at least in part, by the higher level of physical activity in the patients in Brazil in relation those other countries. (20) However, it is important to emphasize that, in the present study, the patients in the groups analyzed were overweight for COPD patients (mean BMI = 27.6 kg/m 2 ), a fact that can explain the low dyspnea scores (MRC scale) obtained since it is known that a low BMI also promotes the onset of dyspnea.…”

A correlação entre o desempenho físico funcional de membros inferiores e a gravidade da doença pulmonar obstrutiva crônica

“…Contudo, segundo Silva, Marrara, Marino, Di Lorenzo e Jamani (17), o grau de obstrução ao fluxo aéreo não é um bom preditor de debilidades musculares em portadores de DPOC. Os achados espirométricos são limitados quando se pretende predizer a capacidade funcional para as AVD (18,19) e para a capacidade de exercício (20,21).…”
