We assessed the impact of the minimum legal drinking age (MLDA) on hospital-based treatment for alcohol-related conditions or events in Ontario, Canada. <\/jats:p><jats:p> Methods. We conducted regression\u2013discontinuity analyses to examine MLDA effects with respect to diagnosed alcohol-related conditions. Data were derived from administrative records detailing inpatient and emergency department events in Ontario from April 2002 to March 2007. <\/jats:p><jats:p> Results. Relative to youths slightly younger than the MLDA, youths just older than the MLDA exhibited increases in inpatient and emergency department events associated with alcohol-use disorders (10.8%; P\u2009=\u2009.048), assaults (7.9%; P\u2009&lt;\u2009.001), and suicides related to alcohol (51.8%; P\u2009=\u2009.01). Among young men who had recently crossed the MLDA threshold, there was a 2.0% increase (P\u2009=\u2009.01) in hospitalizations for injuries. <\/jats:p><jats:p> Conclusions. Young adults gaining legal access to alcohol incur increases in hospital-based care for a range of serious alcohol-related conditions. Our regression\u2013discontinuity approach can be used in future studies to assess the effects of the MLDA across different settings, and our estimates can be used to inform cost-benefit analyses across MLDA scenarios. <\/jats:p>","DOI":"10.2105\/ajph.2013.301320","type":"journal-article","created":{"date-parts":[[2013,10,17]],"date-time":"2013-10-17T20:01:43Z","timestamp":1382040103000},"page":"2284-2291","source":"Crossref","is-referenced-by-count":24,"title":["Effects of the Minimum Legal Drinking Age on Alcohol-Related Health Service Use in Hospital Settings in Ontario: A Regression\u2013Discontinuity Approach"],"prefix":"10.2105","volume":"103","author":[{"given":"Russell C.","family":"Callaghan","sequence":"first","affiliation":[{"name":"Russell C.
