Abstract
Aim: We aimed to examine the influence of pulmonary rehabilitation (PR) on pulmonary function test, body composition, exercise capacity, the perception of dyspnea, quality of life, muscle strength, anxiety and depression scores in obese and non-obese COPD patients.
Methods: We conducted a retrospective study of 82 patients with COPD who completed out-patient PR at our center. Body habitus categories were determined based on BMI. Underweight patients (BMI<=21 kg/m2) were excluded from the analysis. Normal weight and overweight patients (21< BMI < 30 kg/m2) were classified as non-obese. Patients with BMI >=30 kg/m2 were classified as obese. Baseline and post-rehabilitation, pulmonary function test, BMI, fat-free mass (FFM), fat-free mass index (FFMI), waist-hip ratio, incremental shuttle walk test (ISWT), endurance time, MRC, exercise BORG, St. George's Respiratory Questionnaire (SGRQ), deltoid and quadriceps muscles' strength, Hospital Anxiety and Depression Scale (HADS) scores were compared between two classes.
Results: There were greater decrement of BMI (p=0.019), FFM, FFMI and FVC (p<0.05) in obese group than in non-obese group.
Compared to the baseline, decrement in post-rehabilitation SGRQ scores (symptom, activity, impact), MRC, HADS-scores and increment in FVC, FEV1, distance of ISWT and muscle strenght were statistically significant in non-obese group (p<0.05).
Compared to baseline, decrement in post-rehabilitation SGRQ scores (symptom, activity, impact), MRC, HADS-scores, FFMI and increment in distance of ISWT, quadriceps muscle strenght were statistically significant in obese group (p<0.05).
Discussion: We concluded that both in obese and non-obese groups outcomes of PR in COPD patients are similar.
