Prevalence of nutritional depletion in a large out-patient population of patients with COPD

Objective: The present study focuses on the prevalence of nutritional depletion in relation to functional performance, airflow limitation, experienced dyspnoea and health status in a large multi-center out-patient population with chronic obstructive pulmonary disease (COPD).Methods: In 39 out-patient centers in The Netherlands, 389 patients with moderate to severe COPD (217 men) were recruited. The study evaluated on the baseline characteristics of the COSMIC study. Measurements included body composition by bioelectrical impedance analysis, dyspnoea by MRC-score, peripheral muscle function by isometric handgrip strength and disease-specific health status by St. George Respiratory Questionnaire.Results: The prevalence of nutritional depletion (defined as body mass index (BMI)Conclusions: The prevalence of nutritional depletion was high in a large out-patient COPD population in The Netherlands, especially in female COPD patients. Depletion of FFM was associated with impaired peripheral muscle strength, independent of disease severity. (c) 2005 Elsevier Ltd. All rights reserved.
