Although there are a large number of studies focused on binge drinking and traffic risk behaviors (TRB), little is known regarding low levels of alcohol consumption and its association to TRB. The aim of this cross-sectional study is to examine the association of low to moderate alcohol intake pattern and TRB in college students in Brazil. 7037 students from a National representative sample were selected under rigorous inclusion criteria. All study participants voluntarily fulfilled a structured, anonymous, and self-questionnaire regarding alcohol and drug use, social-demographic data, and TRB. Alcohol was assessed according to the average number of alcoholic units consumed on standard occasions over the past 12 months. The associations between alcohol intake and TRB were summarized with odds ratio and their confidence interval obtained from logistic regression. Compared with abstainers students who consumed only one alcohol unit had the risk of being a passenger in a car driven by a drunk driver increased by almost four times, students who reported using five or more units were increased by almost five times the risk of being involved in a car crash. Compared with students who consumed one alcohol unit, the risk of driving under the influence of alcohol increased four times in students using three alcohol units. Age group, use of illicit drugs, employment status, gender, and marital status significantly influenced occurrence of TRB among college students. Our study highlights the potential detrimental effects of low and moderate pattern of alcohol consumption and its relation to riding with an intoxicated driver and other TRB. These data suggest that targeted interventions should be implemented in order to prevent negative consequences due to alcohol use in this population.
尽管有大量研究关注狂欢饮酒和交通风险行为（TRB），但对于低水平的酒精摄入及其与 TRB 的关系知之甚少。本横断面研究旨在探讨巴西大学生中低至中度酒精摄入模式与 TRB 的关系。根据严格的纳入标准，从全国代表性样本中选择了 7037 名学生。所有研究参与者自愿填写了一份关于酒精和毒品使用、社会人口统计学数据以及 TRB 的结构化、匿名和自我问卷。根据过去 12 个月内标准场合平均摄入的酒精单位数评估酒精。使用逻辑回归获得比值比及其置信区间，总结酒精摄入与 TRB 之间的关联。与不饮酒的学生相比，仅饮用一个酒精单位的学生作为醉酒司机驾驶的汽车乘客的风险增加了近四倍，报告使用五个或更多酒精单位的学生发生车祸的风险增加了近五倍。与饮用一个酒精单位的学生相比，使用三个酒精单位的学生酒后驾车的风险增加了四倍。年龄组、非法药物使用、就业状况、性别和婚姻状况显著影响大学生发生 TRB 的情况。我们的研究强调了低至中度酒精摄入模式的潜在有害影响及其与乘坐醉酒司机和其他 TRB 的关系。这些数据表明，应该针对这一人群实施有针对性的干预措施，以防止因饮酒而产生的负面后果。
