Sažetak
Introduction: An increasing number of patients with asthma and chronic obstructive pulmonary disease (COPD) and coexisting obesity are being referred to pulmonary rehabilitation (PR). Aim: To compare one of PR's outcomes – exercise capacity measured by 6-minute walking distance (6MWD) among asthma and COPD patients in regards to body mass index (BMI). Methods: Study included 107 COPD and 80 asthma patients divided to: “non-obese” (normal and overweight, BMI<30) and “obese” (BMI≥30). There was no baseline difference between obese and non- obese group's obstruction level measured by FVC, FEV1, FEV1/FVC .Obese and non-obese asthma and COPD patients attended four-week standard PR, five days weekly. Baseline and post PR results were compared for non-obese and obese in asthma and in COPD group. Results: After PR both asthma and COPD patients, regardless of BMI, had statistically significant increase in 6MWD (p<0.01). COPD non-obese patients improved 6MWD more than obese COPD patients and the difference in 6MWD pre and post PRP is clinically but not statistically significant (Δ=41.17m ; p=0, 517). Asthma non-obese patients also improved 6MWD more than obese asthma patients and that difference is statistically significant (Δ=66.94m ; p<0, 05). For both asthma and COPD patients, correlation between BMI and 6MWD is negative, but statistical significance was proven only in asthma group (r= - 0.261 ; p<0, 05). Conclusion: Pulmonary rehabilitation improves exercise capacity in asthma and in COPD patients. Asthma and COPD patients follow the same pattern regarding BMI ; non-obese patients profit more from PR than do obese patients. Weight reduction in obese patients should therefore be strongly encouraged before and during PR.
