背景：近年来，世界各地的社会运动要求对教育系统和其他机构进行改革。虽然这种流动影响了多个国家的大量人口，但我们对它们对人口健康的影响知之甚少。我们关注一个例子：智利全国各地的中学发生大规模罢工和集体占领，与此同时，这一年龄组的学生使用大麻的情况大量增加。我们的目的是评估的因果关系的影响，2011年智利学校罢工对青少年的物质使用，包括开始使用大麻和使用酒精和marijuan.Methods：学校层面，汇总面板设计使用的数据，从2005年至2015年的全国中学生药物调查学生在9-12年级。我们使用了固定效应的差异中的差异模型来估计学校职业对自我报告的吸毒指标的流行率的影响。结果：2009年至2013年期间，智利青少年中报告的大麻使用增加了一倍。在控制了结果的长期趋势和学校特征后，没有证据表明大麻的开始，酒精和大麻的使用增加，或者青少年中大量使用大麻的增加直接归因于2011年的学校罢工和占领。结论：2011年智利占领学校运动对智利青少年的物质使用没有可检测的因果关系。从2009年到2013年，大麻使用的增加似乎是学龄人口中发生的更广泛的社会变化的一部分。
Background: Recently, social movements across the world have demanded reforms to education systems and other institutions. Although such movements have affected large numbers of people across multiple countries, we know little about the impacts they have had on population health. We focus on one example: the massive strikes and collective occupation of secondary schools across Chile, which occurred contemporaneously with a large increase in marijuana use among students in this age group. We aimed to evaluate the causal effects that the 2011 Chilean school strikes had on adolescent substance use, including the initiation of marijuana use and the use of alcohol and marijuana.Methods: School-level, aggregated panel design using data from the National Drug Surveys among Secondary Students from 2005 to 2015 for students in grades 9-12. We used a fixed-effects difference-in-difference model to estimate the effect of school occupations on prevalence of self-reported indicators of drug use.Results: Reported marijuana use doubled between 2009 and 2013 among Chilean adolescents. After controlling for secular trends in outcomes and for school characteristics, there was no evidence of increased marijuana initiation, alcohol and marijuana use, or of an increase in heavy use among adolescents being directly attributable to school strikes and occupations in 2011.Conclusions: The 2011 Occupy school movement in Chile had no detectable causal effect on substance use among Chilean adolescents. The increase in marijuana use from 2009 to 2013 seems to be part of broader social changes occurring among the school-age population.
