We evaluated the impact on alcohol intake and blood alcohol concentration (BAC) of a multi-level structural intervention to increase the availability of free water, coupled with messaging on pacing alcohol intake and normative feedback of blood alcohol concentration in a convenience sample of gay bars in San Francisco. Participants (n = 1,293) were recruited among exiting patrons of four gay bars (two intervention bars and two control bars). Participants were surveyed on alcohol intake and BAC was measured by breathalyzer. Prior to the intervention there were no significant differences in baseline alcohol measures between intervention and control bars. Post-intervention there were significant differences on objective and subjective measures of alcohol consumption: 30% of intervention bar participants had BAC% levels over the legal driving limit (0.08%) compared to 43% of control bar participants, p < 0.0001 and 78% of intervention bar participants were above the AUDIT-C cut-off for hazardous drinking compared to 87% in control bars, p < 0.001.
我们评估了一项多层次结构干预措施对酒精摄入量和血液酒精浓度（BAC）的影响。该干预措施旨在增加免费水的供应，并在旧金山同性恋酒吧的便利样本中，结合关于控制饮酒节奏的信息以及血液酒精浓度的规范反馈。参与者（n = 1293）是从四家同性恋酒吧（两家干预酒吧和两家对照酒吧）的出门顾客中招募的。对参与者进行了酒精摄入量调查，并通过呼气酒精含量测定仪测量血液酒精浓度。干预前，干预酒吧和对照酒吧之间的基线酒精测量值没有显著差异。干预后，在酒精消费的客观和主观测量方面存在显著差异：干预酒吧30%的参与者血液酒精浓度超过法定驾驶限制（0.08%），而对照酒吧为43%，p < 0.0001；干预酒吧78%的参与者超过危险饮酒的AUDIT-C临界值，对照酒吧为87%，p < 0.001。
