Abstract

HARO-GARCIA, Luis et al. Type 2 diabetes in Mexican workers exponed to a potential source of dioxins in the cement industry determined by a job exposure matrix. Med. segur. trab. [online]. 2010, vol.56, n.219, pp.114-123. ISSN 1989-7790.

Purpose: To identify association between type 2 diabetes (DM2) with occupational exposure to potential dioxins source in Mexican cement industry workers. Materials and Methods: 56 medical files of cement industry workers with diagnosis of DM2 were included; 56 medical files of workers from the same industry without DM2 were the controls. The daily dose of exposure (DDE) to the potential dioxins source per work years was estimated by a job exposure matrix and categorized as low, moderate, and high. Logistic regression model that correlated high exposure to potential source of dioxins (cement clinker confinement) per work years and presence of DM2 was adjusted by work seniority, patient age at which DM2 diagnosis was established and DM2 familiar background. Results: the OR for the presence of DM2 in workers with moderate and high exposure to potential source of dioxins in the cement industry was 3.25 (1.10-9.57), p= 0.03, adjusted by work seniority, worker age at which DM2 diagnosis was established, and DM2 familiar background. Conclusions: In according with the data explored in the medical files of cement industry workers, there is an association between high exposure to the industrial confinement of the cement clinker as a potential source of dioxins and presence of DM2 in a modest dose-response gradient.
