Aim: To determine the frequency of chronic obstructive pulmonary disease as occupational lung disease among brick kiln workers and to compare the frequency of chronic obstructive pulmonary disease among brickyard workers and the surrounding population. Study design: Comparative study - cross-sectional (analytical). Place and duration of the study: Jinnah Hospital, Lahore from March 2019 to March 2020. Methods: This was a Comparative - cross sectional (analytical) study conducted on 407 kiln workers and 407 non kiln workers. Results: The average age of participants was 35 years. The main symptoms in the study group (57% v / s 6%) were cough, (33% v / s 3%) sputum and (14% v / s 1%) dyspnea. Spirometric results showed that chronic obstructive pulmonary disease (18, 9% v / s 2.6%, p <0.01) in brick kiln workers compared to controls living within five kms away from kiln. Conclusion: Brick kilns workers have a higher risk of developing chronic obstructive pulmonary disease (18.9% v / s 2.6%) than controls living outside the brick industry. Key words: occupational risk, chronic obstructive pulmonary disease, lung function test.
