INTRODUCTION: Inhalation of asbestos fibers can lead to a range of diseases, including asbestosis, pleural plaques, lung cancer, and malignant mesothelioma. Despite regulatory efforts, asbestos-related diseases remain a significant public health issue.
OBJECTIVES: This study aimed to assess the characteristics and prevalence of asbestos-related diseases among exposed workers.
METHODS: We conducted a descriptive cohort study with underground workers in Buenos Aires, Argentina, from March 2018 to March 2023. A comprehensive screening and surveillance program, including medical examinations, was implemented to identify exposure-related signs and symptoms. Histological sections from paraffin-embedded tissue blocks were analyzed using light and polarization microscopy for lung cancer cases.
RESULTS: A total of 2,690 participants were included, of whom 2.8% (n = 77) had asbestos-related diseases and 0.22% (n = 6) had lung cancer. Occupational exposure exceeding 20 years was significantly associated with an elevated risk of asbestos-related diseases (odd ratio: 3.02; 95%CI 1.7-5.3).
CONCLUSIONS: The prevalence of occupational diseases among underground workers was consistent with findings from other surveillance programs for asbestos-exposed workers. Occupational exposure exceeding 20 years emerged as a significant risk factor, markedly increasing the likelihood of asbestos-related diseases.
