Audiological profile of agricultural drivers exposed to noise and hydrocarbons Perfil audiológico de motoristas agrícolas expostos: ruído e hidrocarbonetos

Purpose: To establish the audiological profile of agricultural drivers simultaneously exposed to noise and hydrocarbons. Methods: The study comprised analysis of the medical records of agricultural drivers with hearing complaints, from an agricultural company of Lençóis Paulista (SP), Brazil, within the Environmental Risk Prevention Program. The information analyzed included age, period of simultaneous exposure to noise and hydrocarbons and testing of reference pure tone audiometry. Survival models for grouped data (proportional risk and logistic) were adjusted to analyze the influence of age and period of exposure of hearing thresholds. Results: It was observed that the effects of age and period of simultaneous exposure to noise and hydrocarbons were significant for hearing loss in proportional risk and logistic models. Conclusion: It is fundamental to develop actions for the prevention of hearing loss in agricultural drivers exposed to the agents noise and
