[Body composition analysis performed by bioimpedance in patients with chronic obstructive pulmonary disease].

Body composition disorders are observed in chronic obstructive pulmonary disease (COPD) patients and have a significant impact the general condition and outcome in this disease.

AIM: The aim of the study was to assess body composition in relation to airway obstruction severity in patients with COPD.

MATERIALS AND METHODS: The study group consisted of 143 patients (58F, 85M) in the middle age The group was divided to two groups: group A FEV1<50% predicted and group B FEV1 ≥50% predicted; both groups were compared. The following anthropometric parameters were assessed: body mass index (BMI), waist/hip ratio and shoulder circumference of the dominant upper limb. Body composition analysis was performed by bioimpedance (Tanita T5896, TANITA Corporation of America, Inc, Arlington Heights, USA).

RESULTS: The mean BMI for the whole group was 27.5±5.1 kg/m2. None of the patients was underweight, 47 (32.9%) had normal BMI, 55 (38.5%) overweight and 41 (28.6%) were obese. Patients in group A had lower BMI, FFMI and muscle mass index (MMI) than patients in group B. We found the correlation between BMI, FFMI, MMI and FEV1 in the studied group.

CONCLUSIONS: Our results confirm the relationship between airflow limitation and body compositions in COPD patients. We suggest that anthropometric measurements should be a part routine COPD management.
