[Driving-related behavior: an epidemiologic study of undergraduate students].

The purpose of this article was to describe self-reported driving-related behavior and compare the frequency of risk-taking among drivers with and without a history of traffic accidents (TA). A cross-sectional study was designed, and 2,116 undergraduate students from a public university in Brazil ranging in age from 18 to 25 were interviewed. Association between independent variables and history of TA was described using frequency, chi2, p, odds ratio, and 95% confidence intervals. Male data were analyzed through logistic regression. Men showed a higher risk than women of having been involved in TA. Drivers with more frequent risk-taking had a greater risk of history of TA. Behaviors observed to be associated with TA in men were: "history of fines", "driving on the shoulder", and "drinking and driving". Open-ended questions demonstrated that students show low awareness of their own responsibility in TA. Interventions among students are necessary and must prioritize males and mainly those from upper socioeconomic groups.
