ABSTRACT

Background and Objectives: This study was done to assess the prevalence of respiratory morbidity using PEFR and to evaluate factors associated with it. Methods: A cross-sectional survey was carried across Pune. Total 100 workers working at construction sites for 1-10 years were randomly recruited. The purpose of the study was explained and an informed consent was taken. All subjects were interviewed using respiratory surveillance questionnaire and the PEFR was recorded. Statistical analysis was done using independent t-test and ANOVA test. Results: Total 73 workers aged 25-30 years (59 males, 14 females) and 27 workers aged 30-35 years (25 males, 2 females) were surveyed. The mean PEFR was less in carpenters (330, ±56.56) than tile fixators (380, ±62.98), masons (360.8, ±79.71) and welders (372, ±75.68). The mean PEFR varied significantly with years of exposure and was 285(±49.49) in workers with 2 years exposure; 420.9(±81.17) of those exposed for 2-4 years; 391(±69.90) for 4-6 years, 357.39(±80.06) for 6-8 years, 328.12(±71.94) for 8-10 years and 340.47(±65.53) for more than 10 years of exposure. The mean PEFR of smokers was higher 372.4(±67.25) than that of non-smokers 360.6(±79.28). The mean PEFR of workers exposed to animals was higher 401(±79.36) than those who are not exposed to animals 359.5(±75.51). Conclusion: The study showed significant respiratory morbidity among the construction workers which varied with job profile, years of exposure and comorbid factors such as smoking, exposure to allergens and use of protective measures.
