Abstract

Indian cement industry is the second largest in the world. With growing industrialization more and more people are involved in industrial occupation, who are prone to serious health hazards. In the present study we focus on pulmonary function tests (PFT) the changed values correlating with the duration of stay and type of occupation in the cement factory area. A base line demographic and patient data of work and stay was taken with the help of questionnaires designed as data collection form. Patients were sent for pulmonary function test which was done by an experienced PFT technician. Mean age of study subjects was found out to be 40.54 years (± 8.91). The different occupations of subjects staying in the said areas can be summarized as 8 house wives, 22 technicians, 4 hospital workers, 6 mine workers, 6 security personnel and 3 drivers. Mean duration of work and stay was found out to be 13.08 years (± 10.55) and 16.78 years (± 13.32) respectively. The mean forced expiratory volume in the first second (FEV₁) was found out to be 71.28 (± 20.74) whereas peak expiratory flow rate (PEFR) was found to be 68.1 (± 17.20). 6 subjects had a history of asthma, 13 had dust allergy, 18 had shortness of breath functional class (FC) - grade III, and 2 patients working in mines had silicosis. There was a negative correlation between duration of stay and FEV₁, PEFR with a co-efficient of correlation being -0.4 (p-value 0.29) & -0.43 (p-value 0.1) also the duration of work and FEV₁, PEFR with a co-efficient of correlation being -0.51 (p-value 0.4) & -0.3 (p-value 0.7).

Key words: Cement factory; pulmonary function tests; forced expiratory volume; peak expiratory flow rate; occupational lung diseases.
