Nutritional status is related to fat-free mass, exercise capacity and inspiratory strength in severe chronic obstructive pulmonary disease patients

摘要

INTRODUCTION: Being overweight or obese is associated with a higher rate of survival in patients with advanced chronic obstructive pulmonary disease (COPD). This paradoxical relationship indicates that the influence of nutritional status on functional parameters should be further investigated. OBJECTIVE: To investigate the impact of nutritional status on body composition, exercise capacity and respiratory muscle strength in severe chronic obstructive pulmonary disease patients. METHODS: Thirty-two patients (nine women) were divided into three groups according to their body mass indices (BMI): overweight/obese (25 < BMI < 34.9 kg/m2, n=8), normal weight (18.5 < BMI < 24.9 kg/m2, n=17) and underweight (BMI
