Abstract
Background: Occupational Asthma is characterized by reversible airway obstruction, either spontaneously or with treatment, airway inflammation and increased airway responsiveness due to workplace exposure. It is the most common occupational lung disease in developed countries. One of causative agent is metal fume that may be encountered in steel industries. In this study we determined occupational asthma prevalence in one steel factory and then we classified results according to various workshops.
Methods: In this cross sectional study we determined workshops for 450 workers of steel industry by questionnaire. Then cross shift spirometry was done in all of them.
Results: In cross shift spirometry we detected 14 occupational asthma cases. Highest prevalence was in catering (25%) and other workshops according to prevalence were welding (10%), construction (7%), scrap (5%), roller and lathes and melting (3%).
Conclusion: There is great variability for occupational asthma in different workshops of steel industry. Highest prevalence was in catering that its exposures is different from other workshops in steel industry .It seems that this kind of exposures is more asthmogen than metal fumes

Abstract
Abstract
Background: Asthma is a common respiratory disease that causes occupational disability. Specific occupations may be related to induction or exacerbation of asthma. The objective of present study was descriptive evaluation of occupations in asthmatic patients.
Methods: In this cross ـsectional study, 339 asthmatic patients older than 17 years were evaluated regarding their occupations. One hundred and seventy nine patients had at least one occupation. Their occupations were classified based on Standard Occupational Classification 1991(SOC-91) and frequency of asthmatic patients was determined for each occupational group.
Results: The most frequent occupation in our asthmatic patients was trades, transport and equipment operators and related occupations (66 cases, 36.87%). In this occupational group, the most frequent occupation belonged to taxi driving (13 patients, 7.2%). After that, sales And service occupations such as hairstylists and barbers, bakers and food service providers were frequent occupations (39 cases, 22.3%). The less frequent occupations in our asthmatic patients were management occupations (2 cases) and health occupations (one case).
Conclusion: Asthma may be more frequent in some occupations such as trades, transport and equipment operators and related occupations and after that sales and service occupations. Evaluation of worsening asthma symptoms in mentioned occupations is recommended.
