PURPOSE: To assess prevalence of Chronic obstructive pulmonary disease and its relationship to smoke exposure among persons attending the Master Health Check program of a tertiary hospital in South India between 2011 to 2012.

METHODS: A specifically designed questionnaire, (1) was administered to each subject followed by both pre - and post- bronchodilator spirometry. COPD was suspected from the presence of cough and expectoration on most of the days for at least three months in a year for two consecutive years or more and diagnosis confirmed by spirometry.

RESULTS: 550 subjects were studied. 170 were smokers, 83 current smokers and 97% male smokers. Cigarette was smoked predominantly.36% had biomass fuel exposure. 275 (50%) subjects in the total study population had COPD using the spirometric criteria according to GOLD guidelines (2), of which 67.3% were males. 243 asymptomatic and 32 symptomatic subjects were diagnosed with COPD by spirometry. 54.11% smokers and 48.16% nonsmokers had COPD. Among smokers with COPD, prevalence was higher among cigarette (27.64%) than bidi smokers (2.55%). Self cooking people had a significant association with COPD and there was a statistically significant difference among those involved (46.97) or not involved (51.7%) in cooking at home. 44.7% had Mild (GOLD1), 38.2% moderate (GOLD2), 14.2% severe COPD (GOLD 3) and 2.9% very severe COPD (GOLD 4). Higher risk for women, older individuals, urban residence, and tobacco smoking was observed. The risk was significantly more for smokers of all kinds. No significant association of COPD observed with the type of cooking fuel used at home.

CONCLUSIONS: Surprisingly nearly half of the subjects had varying severities of COPD with higher symptoms amongst Tamil Nadu and West Bengal subjects. There was statistically significant association of COPD with advancing age, tobacco smoking and exposure to biomass fuels.

CLINICAL IMPLICATIONS: The results of this unique study represent a fair degree of cross-sectional data from multiple South Eastern states of India and may be used for assessment of the national burden of COPD among the elite strata of society.
