Background: The cement plant workers are exposed to fine cement dust, which irritates the mucous membranes of the respiratory airways, and leads to reduction in pulmonary functions among exposed workers. Hypothesis: The study is based on the hypothesis that cement dust affects the pulmonary functions Aim: To record and compare the pulmonary functions among the subjects exposed to cement dust directly with that of non exposed subjects taken from general population of Bagalkot. Methods: A total of 132 apparently healthy age and sex matched subjects 66 cement factory workers who were directly exposed to cement dust and 66 subjects from general population of Bagalkot were selected. Forced expiratory spirograms were recorded by Helios 401 hand held portable computerized spirometer [M/s Recorders & Medicare Systems Ltd. India]. Parameters such as Forced Vital Capacity[FVC], Forced Expiratory Volume in 1st second [FEV1], the ratio of FEV1/FVC, Forced Expiratory Flow in the middle half of FVC[FEF25-75%] and Peak Expiratory Flow Rate [PEFR] were assessed and statistically analysed using students 't' test and ANOVA. 25-75% Result: Statistically significant reduction in FVC, FEV1, and PEFR was found in exposed workers as compared to the non-exposed. 1 Although FEV /FVC ratio and FEF25-75% was less in exposed workers, the difference was found to be insignificant.
