Drink driving is widely recognized as a major road safety problem. In Australia, health promotion messages encourage monitoring the number of standard drinks consumed prior to driving. This pilot research aimed to investigate commuting behavior and blood alcohol concentration (BAC) of diners, including intended drivers, at Sunshine Coast restaurants.
Five hundred and forty-four diners (n = 260 males) consented to participate in a brief interview and to use a breathalyzer device to measure their BAC.
Forty percent of participants advised they don't drink and drive (34% of males, 45% of females; 67.25% of <17-20 years, 30.5% of 50-59 years), and of the remaining participants, 75% advised they count the number of their drinks (69% of males, 84% of females; 32% of <17-20 years, 82% of 50-59 years), while 10% of participants monitored their BAC by how they were feeling (12% of males, 6% of females). Thirty-seven percent of participants said it was easy/very easy to estimate their BAC (41% of males; 33% of females; 21% of <17-20 years, 43% of 50-59 years). The actual BAC was less than expected for 56% of participants, with one-third underestimating BAC and some intended drivers having an actual BAC in excess of the 0.05 limit.
Given the proportion of diners who reported they count the number of drinks, or use feelings as a way to gauge BAC, coupled with the considerable proportion who underestimated their BAC, a safer public health message is to avoid driving if you intend to drink. In addition, targeted intervention for experienced drivers (and, arguably, drinkers) appears warranted, as every participant aged less than 21 years who stated he or she would drive home indeed had a zero BAC. Interestingly every female driver who stated she would be driving home also had a legal BAC, suggesting gender-specific intervention.
酒后驾车被广泛认为是一个主要的道路安全问题。在澳大利亚，健康促进信息鼓励人们在开车前监测饮用的标准饮品数量。这项初步研究旨在调查阳光海岸地区餐厅用餐者（包括有意驾车者）的通勤行为和血液酒精浓度（BAC）。
544名用餐者（n = 260名男性）同意参与简短访谈，并使用呼气酒精含量测定仪测量他们的BAC。
40%的参与者表示他们不会酒后驾车（男性为34%，女性为45%；17至20岁以下的为67.25%，50至59岁的为30.5%），在其余参与者中，75%表示他们会计算饮酒量（男性为69%，女性为84%；17至20岁以下的为32%，50至59岁的为82%），而10%的参与者通过自身感觉来监测BAC（男性为12%，女性为6%）。37%的参与者表示很容易/非常容易估计自己的BAC（男性为41%；女性为33%；17至20岁以下的为21%，50至59岁的为43%）。56%的参与者实际BAC低于预期，三分之一的人低估了BAC，一些有意驾车者的实际BAC超过了0.05的限制。
鉴于报告会计算饮酒量或通过感觉来判断BAC的用餐者比例，以及相当一部分人低估了自己的BAC，更安全的公共卫生信息是如果打算饮酒就避免开车。此外，对有经验的驾驶者（可以说，饮酒者）进行有针对性的干预似乎是必要的，因为每个表示会开车回家的21岁以下参与者的BAC确实为零。有趣的是，每个表示会开车回家的女性驾驶者的BAC也都在合法范围内，这表明需要进行针对性别的干预。
