Abstract
JUAREZ-PEREZ, Cuauhtémoc Arturo et al. Neuropsychological effects among workers exposed to organic solvents. Salud pública Méx [online]. 2019, vol.61, n.5, pp.670-677. Epub Aug 07, 2020. ISSN 0036-3634. https://doi.org/10.21149/9800.
Objective:
To assess neuropsychological performance among workers at a paint factory in Mexico City.
Materials and methods:
During 2004 and 2005 we assessed the neuropsychological performance of 208 workers who were exposed to organic solvents at a paint factory, mainly toluene and xylene. We categorized workers into low and high exposure groups using a cumulative index for toluene, based on times spent in different tasks. We evaluated cognitive and motor functions with 13 neuropsychological tests.
Results:
We found lower attention, longer time to complete the test β=5.5 (R2=12.3%), and a lower score in the motor-cognitive test β=-15.7 (R2=19.5%) in the high exposure group through multiple linear regression model analysis, with adjustment for age and education.
Conclusion:
Our results are similar to the ones reported in the literature, but the effects are less severe, probably due to lower exposure to organic solvents.
