Determine the effect of a partial sales ban on cross border drinking in Mexico.
On weekend evenings, thousands of youths (younger than 21 years) and young adults (21 to 25 years) residing in communities along the U.S. border cross over into Mexico to patronize all-night bars where the drinking age is 18 rather than 21 years and where the price of alcohol is considerably less than in the United States. On January 1, 1999, Juárez, Mexico, across the border from El Paso, Texas, implemented a 2 AM bar closing policy replacing the previous 5 AM closing time. Breath alcohol tests of pedestrians at the Juárez/El Paso border before and after the policy change were compared with a similar sample of pedestrians at the Tijuana, Mexico/San Diego, California border.
At the Juárez/El Paso border, the total number of youths with positive BACs returning from Juárez after 3 AM when the bars were closed was reduced 89%, whereas the number returning between midnight and 3 AM remained unchanged. There was no change in either period at the Tijuana/San Diego comparison site.
Early closing of the bars in Juárez reduced the number of youths returning after 3 AM to the United States with positive BACs.
确定部分销售禁令对墨西哥跨境饮酒的影响。
在周末晚上，数千名居住在美国边境沿线社区的年轻人（21岁以下）和青年成年人（21至25岁）越过边境进入墨西哥，光顾通宵营业的酒吧，这些酒吧的饮酒年龄为18岁而非21岁，且酒精价格远低于美国。1999年1月1日，墨西哥华雷斯市（与得克萨斯州埃尔帕索市隔边境相望）实施了凌晨2点酒吧关门政策，取代了之前凌晨5点的关门时间。将政策变更前后在华雷斯/埃尔帕索边境对行人进行的呼气酒精测试结果，与在墨西哥蒂华纳市/加利福尼亚州圣地亚哥边境对行人进行的类似样本测试结果进行比较。
在华雷斯/埃尔帕索边境，酒吧关门后凌晨3点以后从华雷斯返回且呼气酒精含量阳性的年轻人总数减少了89%，而午夜至凌晨3点之间返回的人数保持不变。在蒂华纳/圣地亚哥对比地点，这两个时间段均未出现变化。
华雷斯市酒吧提前关门减少了凌晨3点以后呼气酒精含量阳性的年轻人返回美国的数量。
