The aims of the present study were to characterize fatal traffic accident victims in a major urban center in Brazil and their association with alcohol consumption.
Cross-sectional study of 907 fatal traffic accident victims in Sao Paulo, in 2005.
Adult males between the ages of 25 and 54 represented the majority of cases with positive blood alcohol concentrations (BAC). Overall, males had a higher proportion of BAC and mean BAC than females. Pedestrians, particularly those with no detectable BAC, were typically older than other victims. Most accidents (total and BAC-positive) happened on weekends between midnight and 6 a.m. Considering all victims, 39.4% were positive (BAC over 0.1g/l). When only drivers (automobile, motorcycle and bicycle) were evaluated, 42.3% had BAC over the legal limit (0.6g/l).
Alcohol is associated with nearly half of all traffic accident deaths in the city of Sao Paulo, especially for days and times associated with parties and bars (weekends between 12 a.m. and 6 a.m.).
本研究旨在描述巴西一主要城市中心致命交通意外事故受害者的特征，并分析其与酒精消费之间的关联。
2005 年，对巴西圣保罗市 907 名致命交通意外事故受害者进行了横断面研究。
血液酒精浓度（BAC）呈阳性的病例中，成年男性（25-54 岁）占多数。总体而言，男性的 BAC 阳性比例和平均 BAC 均高于女性。行人，特别是那些 BAC 未检出的行人，通常比其他受害者年龄更大。大多数事故（总事故和 BAC 阳性事故）发生在周末午夜至早上 6 点之间。考虑所有受害者，39.4%的人呈阳性（BAC 超过 0.1g/l）。当仅评估驾驶员（汽车、摩托车和自行车）时，42.3%的人 BAC 超过法定限制（0.6g/l）。
在圣保罗市，酒精与近一半的交通意外事故死亡事件相关，尤其是与聚会和酒吧有关的时段和日期（周末午夜至早上 6 点之间）。
