In Tijuana, Mexico, a loosely enforced age-18 law and inexpensive drinks have given rise to a nightclub district frequented by thousands of young Southern Californians each weekend night. Surveys were designed to characterize the extent of the cross-border binge-drinking traffic and to support and evaluate the community's response.
Over 1 year, two anonymous and voluntary breath-test surveys were done. Drivers and pedestrians were pulled randomly from the stream of northbound border crossers and recruited to participate.
Surveys occurred between 12 a.m. and 4 a.m. on randomly selected Wednesdays, Fridays, and Saturdays. Participants were recruited within the Port of Entry building.
Of the 5849 border crossers recruited, 87.4% participated in the survey.
Information was obtained through a standardized verbal interview. All participants were asked to take an alcohol breath test.
On weekend nights, more than 6500 people cross back into the United States between 12 a.m. and 4 a.m. after drinking or visiting a bar or restaurant. Pedestrians represent the highest concentration of drinkers, with more than 30% having BACs of 0.08 or greater. Most of these pedestrians return to parked vehicles on the US side and drive or ride home.
The flow of young binge drinkers at the Tijuana border is substantial and translates into a significant public health problem for the region as crossers use their vehicles to drive home. There are many such binge-drinking locales. However, the border is unique in that it is amenable to scientific estimations of the problem with relatively high precision.
在墨西哥的蒂华纳，一项执行宽松的18岁饮酒法律以及价格低廉的酒水，催生了一个夜总会区，每个周末夜晚都有成千上万南加州的年轻人前来光顾。开展调查旨在了解跨境酗酒现象的严重程度，并支持和评估社区的应对措施。
在一年多的时间里，进行了两项匿名且自愿的呼气酒精测试调查。从北行过境人流中随机抽取司机和行人，并招募他们参与调查。
调查在随机选定的周三、周五和周六凌晨12点至4点进行。在入境大楼内招募参与者。
在招募的5849名过境者中，87.4%参与了调查。
通过标准化的口头访谈获取信息。所有参与者都被要求进行呼气酒精测试。
在周末夜晚，有超过6500人在饮酒或光顾酒吧或餐厅后于凌晨12点至4点之间返回美国。行人是饮酒者最集中的群体，超过30%的人的血液酒精浓度达到或超过0.08。这些行人中的大多数回到美国一侧停放的车辆，然后开车或乘车回家。
蒂华纳边境年轻酗酒者的流量很大，由于过境者驾车回家，这给该地区带来了重大的公共卫生问题。有许多这样的酗酒场所。然而，边境的独特之处在于，它适合以相对较高的精度对该问题进行科学估计。
