Objective: To determine the frequency and predictors of chronic bronchitis and COPD among textile workers in Karachi, Pakistan
Study Design: Cross-sectional survey
Place and Duration of Study: Karachi, Pakistan, from October to December 2009
Methodology: Male textile workers from 15 mills of Karachi were inducted. Data was collected using American Thoracic Society respiratory questionnaire [ATS-DLD-78-a] and spirometry
Results: Out of 372 participants, 29 [7.8%] workers had chronic bronchitis [4, 9.1% aged >/= 40 years] and 25 [6.7%] had COPD [12, 27.2% aged >/= 40 years]. Workers with chronic bronchitis had significantly decreased lung function compared to the healthy workers. Those reporting severe self-perceived dust exposure at work, >/= 10 pack years of smoking, uneducated, longer duration of work [>/= 11 years], and ever smokers were more likely to have chronic bronchitis or COPD. In the multivariate analyses, severe self-perceived dust exposure at work [AOR = 7.4; 95% CI: 1.9, 28.0], family history of respiratory illness/symptoms [AOR = 4.8; 95% CI: 1.1, 20.9] and lack of education [AOR = 4.2; 95% CI: 1.1, 16.9] were significant predictors of chronic bronchitis. Duration of work >/= 11 years [AOR = 5.5; 95% CI: 1.5, 19.7] and pack years of smoking >/= 10 years [AOR = 3.5; 95% CI: 1.1, 11.7] were strong predictors for COPD
Conclusion: There is a high frequency of chronic bronchitis and COPD among textile workers. Multiple important predictors for prevention are identified
