ABSTRACT

Objective:

To investigate the association of hours of work and rest with use of psychoactive substances among professional truck drivers.

Methods:

Cross-sectional study conducted in 2016 with 354 professional truck drivers waiting for the inspection of the goods transported at a Fiscal Control Post located in the city of Itatiaia, RJ, Brazil. The association between daily working hours (exposure), daily rest hours (exposure) and use of psychoactive substances (outcome) was investigated using linear regression models that estimated regression coefficients (β) and respective standard error, consideringp< 0.05.

Results:

They were positive the associations between daily working hours and use of amphetamine (β = 0.91; standard error = 0.19;p< 0.01) and cocaine/crack (β = 1.32; standard error = 0.35;p< 0.01) and the association between daily rest hours and use of amphetamine (β = - 0.43; standard error = 0.09;p< 0.01) was negative.

Conclusion:

Daily hours of work and rest seem to be determinants of the use of amphetamine and cocaine/crack among professional truck drivers.
