Although not originally enacted to deter the problem of underage drinking in the United States, one set of laws that may influence this behavior is juvenile curfew laws. This research asked the following: (a) What is the effect of enacting a juvenile curfew law on youth drinking, and (b) do demographic variables moderate the relation between juvenile curfew law enactment and drinking? This study examined the effect of juvenile curfew laws on underage drinking, using data from 46 U.S. cities from 1991 to 2005.
In 2014, we compiled a data set containing alcohol and curfew law data by zip code. It included 63,081 minors (ages 12-17 years) from 1,081 zip codes. We used difference-in-difference regressions to analyze the data.
The effect of the enactment of a curfew law on the likelihood of consuming alcohol in the past year or past 30 days or of heavy episodic drinking in the past 2 weeks was not significant when compared with cities without curfew laws during the same periods. Although the likelihood of consuming alcohol over the past year differed depending on an individual's characteristics (e.g., race/ethnicity, age, and gender), none of the interaction terms between these characteristics and curfew laws were significant.
Curfew laws appear to have a nonsignificant effect on youth drinking, but these results are unclear without more knowledge as to where and when youth are drinking both before and after the enactment of curfew laws and how these laws are being enforced.
尽管美国最初制定的青少年宵禁法并非旨在解决未成年人饮酒问题,但这一系列法律可能会对这种行为产生影响。本研究提出以下问题:(a)颁布青少年宵禁法对青少年饮酒有何影响?(b)人口统计学变量是否会调节青少年宵禁法的颁布与饮酒之间的关系?本研究利用1991年至2005年美国46个城市的数据,考察了青少年宵禁法对未成年人饮酒的影响。
2014年,我们编制了一个数据集,其中包含按邮政编码划分的酒精和宵禁法数据。该数据集包括来自1081个邮政编码地区的63081名未成年人(年龄在12至17岁之间)。我们使用双重差分回归分析数据。
与同期没有宵禁法的城市相比,颁布宵禁法对过去一年、过去30天内饮酒或过去两周内大量饮酒的可能性没有显著影响。尽管过去一年饮酒的可能性因个人特征(如种族/民族、年龄和性别)而异,但这些特征与宵禁法之间的交互项均不显著。
宵禁法似乎对青少年饮酒影响不显著,但如果不了解在宵禁法颁布前后青少年在何时何地饮酒以及这些法律是如何执行的,这些结果就不明确。
