In summary alcohol availability changed throughout the 1969--1976 time period with a particularly major change caused by the 18-year-old legal drinking age (1972) and increases in the numbers and hours-of-operation of on-premise consumption establishments. Eighteen to 20-year-olds experienced increases of at least 4600 additonal traffic crashes associated with alcohol of which at least 89 involved one or more fatalities in the 1972-1975 time period. Associated with the increase in crash involvement, draught beer consumption in Michigan dramatically increased. In the absence of any convincing explanations to the contrary, we consider these conservative analyses to be compelling evidence of the role of alcohol availability in the social etiology of alcohol-related traffic casualties.
总之，在1969年至1976年期间，酒精的可获得性发生了变化，1972年将法定饮酒年龄降至18岁以及经营场所消费场所数量和营业时间的增加导致了特别重大的变化。18至20岁的人群在1972年至1975年期间因酒精导致的交通事故至少增加了4600起，其中至少89起涉及一人或多人死亡。随着事故发生率的增加，密歇根州的生啤酒消费量大幅上升。在没有任何令人信服的相反解释的情况下，我们认为这些保守分析有力地证明了酒精可获得性在与酒精相关的交通伤亡社会病因中的作用。
