    Cellular atypia prevalence in male foundry workers increased with smoking and age. Abnormal findings were more common in smokers, particularly those smoking over 21 cigarettes daily.

    Area of Science:

    • Occupational health
    • Pulmonary pathology
    • Environmental toxicology

    Background:

    • Foundry work involves exposure to dust and fumes.
    • Cellular atypia can be a precursor to neoplastic changes.
    • Smoking is a known risk factor for respiratory diseases.

    Purpose of the Study:

    • To determine the prevalence of cellular atypias in male foundry workers.
    • To investigate the relationship between cellular atypia and smoking history, age, and work department.
    • To assess occupational risks in foundry environments.

    Main Methods:

    • A cross-sectional study involving 677 male foundry workers.
    • Data collection included smoking history, age, and work department.
    • Cytological examination for cellular atypia, with 95% participation.

    Main Results:

    • Abnormal findings (mild/moderate atypia) were present in 10.8% of workers.
    • Prevalence of abnormal findings was 4.2% in non-smokers versus 7.8% in heavy smokers (>21 cigarettes/day).
    • Atypia prevalence increased with age, but only in smokers. Departmental variations were not significant.

    Conclusions:

    • Smoking is a significant risk factor for cellular atypia in foundry workers.
    • Age exacerbates the risk of atypia in smokers.
    • Foundry workers, especially smokers, require targeted screening and intervention strategies.
