Abstract
Studies on COPD have largely focused on the smoking rather than the non-smoking population.
Hence we conducted the study to identify the non-smoking causes of COPD. The study was
conducted in the Department of Tuberculosis and Respiratory Diseases, Jawaharlal Nehru Medical
College, AMU, Aligarh during 2011-2013 on 450 COPD patients. The aim of the study was to find
out proportion of non smokers among all COPD patients, identify risk factors for COPD among non
smokers and classify non-smoking COPD patients according to severity. Maximum patients
(35.41%) among non smoker COPD group had more than one risk factor for COPD. Most of the
patients among non smoker COPD were found to be having severe to very severe disease
(63.5%). 34.4% patients had moderate COPD and very few patients had mild COPD (3%). On
comparing disease severity among non-smoker and smoker COPD patients, we found that
proportion of patients with very severe disease was more in smoker group (39.2% in smoker vs.
29.2% in non smoker), while proportion of patients with mild to moderate disease were more in non
smoker group (35.5% in non smoker vs. 24% in smoker). Patients with severe disease in both
groups were found to be of equal proportion (33.3% in non smoker vs. 36.7% in smoker).
