Actividad física y su relación con el estado de salud en pacientes EPOC estables / Physical Activity and its Relationship with the State of Health of Stable Copd Patients

Introducción: Estudios previos han resaltado que la actividad física (AF) en la EPOC se asocia a mejorcalidad de vida y menor morbimortalidad. Nuestro objetivo ha sido conocer los hábitos de AF en la vidadiaria de pacientes EPOC estables fuera de un programa de rehabilitación respiratoria.Material y métodos: Estudio observacional descriptivo transversal multicéntrico en pacientes EPOC establescontrolados ambulatoriamente por neumólogos. Para conocer el índice de AF (IAF) se utilizó elMinnesota Leisure Time Physical Activity Questionnaire (MLTPAQ), diferenciando según el gasto energético,los siguientes grupos: inactivos (menos de 1.000 kcal/semana), moderadamente activos (entre1.000 y 3.000 kcal/semana) y muy activos (más de 3.000 kcal/semana). Se analizó la relación entre el IAFy variables socioeconómicas, de severidad de la enfermedad y de nivel de salud de los pacientes.Resultados: Se incluyó a 132 pacientes (121 varones). Edad media: 66,3 años, FEV1 medio 45%. Un 32,6%de ellos realizaba una AF menor de 1.000 kcal/semana, un 38,6% entre 1.000 y 3.000 y el 28,8% másde 3.000. Los pacientes EPOC más inactivos, tenían mayor obstrucción bronquial, una enfermedad mássevera, referían más disnea y caminaban menos metros en el 6MWT.Conclusiones: Los pacientes EPOC estables realizan un bajo nivel de AF. Una menor AF se asocia con unpeor estado de salud y con una mayor gravedad de la enfermedad(AU)

Introduction: Previous studies have shown that physical activity (PA) in COPD is associated with a betterquality of life and less morbidity and mortality. Our aim was to study the daily PA in the lives of stableCOPD patients, outside the setting of a pulmonary rehabilitation program.Material and methods: Observational, descriptive and transversal multi-center study in patients with stableCOPD controlled in an outpatient clinic by pneumologists. In order to determine the Physical ActivityIndex (PAI), the Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ) was used to differentiatethe following groups according to the energy expenditure: inactive (less than 1,000 kilocalories perweek), moderately active (between 1,000 and 3,000 kilocalories per week) and very active (more than3,000 kilocalories per week).Weanalyzed the relationship between PAI and disease severity, health level and socioeconomic variables of the patients. Results: A total of 132 patients (121 men) were included in the study. Mean age was 66; mean FEV1was 45%. Regarding PA, 32.6% had energy expenditures of less than 1,000 kilocalories/week, 38.6% between1,000 and 3,000 and 28.8% more than 3,000. The most inactive COPD patients had more bronchialobstruction, more severe disease, more dyspnea and walked fewer meters in the 6MWT.Conclusions: Stable COPD patients perform low levels of PA. Lower PA is associated with poorer healthand with more severe disease(AU)
