Aims:
To estimate the prevalence of malnutrition in chronic obstructive pulmonary disease (COPD) patients hospitalized for exacerbation and to evaluate its clinical and prognostic influence on the exacerbation.
Subjects/Methods:
The subjects were 78 consecutive patients with moderate-to-severe COPD who were admitted to hospital with a diagnosis of exacerbation. Nutritional status was assessed by means of body mass index (BMI), bioelectric impedance analysis and levels of plasmatic albumin. Previous spirometry, 6-min walk test, severity of the exacerbation, days of hospitalization and readmission in the following 3 months were also evaluated.
Results:
Malnutrition [BMI <20 or fat-free mass (FFM) index
Conclusions:
The high prevalence of malnutrition among hospitalized COPD patients is related to their lung function and exercise tolerance. Moreover, nutritional parameters during exacerbation are related to length of hospitalization and readmission.

The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
