Abstract Objecive: We invesigated the relaionships among parameters related to accident involvement, sleep paterns and health habits of shit-working Brazilian truck drivers. Methods: In this cross-secional study, 205 Brazilian truck drivers were invited and accepted to complete our survey based on the validated structured “UNIFESP Sleep Quesionnaire”. A muliple correspondence analysis was used to assess the clustering of evaluated potenial categorical variables with involvement in automobile accidents, aiming to examine associaions between these variables. Results: Our results generated two disinct truck drivers’ proiles. For the irst proile, we observed that drivers who reported involvement in accidents appeared similar to those who reported drug usage, driving more than 14 to 19 hours without rest, excessive sleepiness, falling asleep while driving and sleep complaints. Conversely, the second proile showed that subjects who were not involved in accidents were similar to subjects who reported no sleep complaints or excessive sleepiness, did not falling asleep while driving and did not use drugs. We have also observed that the variable contribuing the most to these two proiles was overnight travel, followed by falling asleep while driving and sleep complaints. Our data also demonstrated that exposure to accidents was 4 imes higher for drivers who habitually drive during the night. We have also observed a protecive efect in terms of accident involvement for drivers who usually work fewer than 12 hours per day. Conclusion: Our results highlighted how adequate sleep habits, as well as, the consequences related to sleep disturbances, are associated with drug consumpion and accident involvement by truck drivers.
