Abstract

OBJECTIVES

This study evaluated the effects on drinking and driving of lowered allowable blood alcohol concentration (BAC) limits for drivers younger than 21 years in 30 US states between 1984 and 1998.

METHODS

Outcome measures were based on self-reports from a cross-sectional sample of more than 5000 high school seniors in 30 states surveyed before and after BAC limits were implemented in their states.

RESULTS

Frequency of driving after any drinking and driving after 5 or more drinks declined 19% and 23%, respectively. Lower BAC limits did not affect overall amount of drinking or total number of miles driven.

CONCLUSIONS

Significant beneficial effects of lowered youth BAC limits have appeared despite limited publicity and enforcement of the new laws.

摘要

目的

本研究评估了1984年至1998年间美国30个州将21岁以下驾驶员的法定血液酒精浓度(BAC)限值降低后对酒后驾车的影响。

方法

结果测量基于对30个州5000多名高中生进行横断面抽样调查的自我报告,这些调查在其所在州实施BAC限值前后进行。

结果

饮酒后驾车的频率以及饮用5杯或更多酒后驾车的频率分别下降了19%和23%。较低的BAC限值并未影响饮酒总量或总行驶里程数。

结论

尽管新法律的宣传和执行力度有限,但降低青少年BAC限值已产生了显著的有益效果。
