Evaluation of frequency of small airway obstruction in obese individuals referring to obesity clinic of Hazrat-e-Rasool Akram hospital, 2011-12

The aim of this cross-sectional study was to determine the frequency of small airways obstruction in obese patients referred to obesity clinic of the Hazrat-e-Rasool Akram Hospital during 2011-12. Retrospectively، the frequency of Small Airway Disease (SAD) in 100 adult obese patients، who had no history of respiratory or cardio-respiratory disorders and did not complain about respiratory problems in recent weeks، and was determined in people with forced expiratory flow at 25-75% of the pulmonary volume (FEF25-75%) less than 60%. The average age was 40. 3 ± 8. 6 years. Twenty-eight percent of subjects were found to suffer from SAD، of those 86% were women and 14% were men. The small airways disease prevalence was found higher in obese than non-obese people. Thus، to reduce the mortality and morbidity it would be recommended to diagnose the pulmonary disorders in obese people.
