What we can do to reduce extreme college drinking
Decades of research, policy changes and intervention efforts have only dented the rate of high-risk binge drinking at Michigan's public universities. Scattershot efforts across universities, college towns and the Capitol have ranged from ineffective to contradictory to, as happened with the keg tag measure, a study in unintended consequences.
Administrators express frustration with a problem for which every solution seems akin to pushing on one side a balloon.
Why Colleges Haven't Stopped Binge Drinking
The Chronicle of Higher Education online
The Higher Education Center for Alcohol and Drug Misuse Prevention and Recovery opened this year at Ohio State University, under the direction of Mr. Clapp, who led the shuttered federal center. He secured grant money, $2-million from the Conrad N. Hilton Foundation, to translate alcohol research into strategies that colleges can use, he says. “The idea is to give people tools that don’t necessarily need a ton of money to implement” or “50 to 60 staff people to run.”
Why Can't NFL and NBA Players Just Stay out of Legal Trouble?
Bleacher Report online
From 2000-2010, law enforcement officials arrested one in every 45 NFL players on average, one-third of those players for drunk-driving....The college-campus setting of Blackmon's case further reveals the situation on the ground, because DUI accounts for the "bulk" of the 1,700 a-year average of alcohol related deaths among college students, according to Dr. John D. Clapp of the US Department of Education's Higher Education Center for Alcohol, Drug Abuse and Violence Prevention.

Few studies have examined the context in which drinkers underestimate their breath alcohol concentration (BrAC) in natural drinking environments. This study examined factors associated with bar patrons’ self-estimated BrAC in high-risk college town settings.

High-risk drinking is considered a major concern in public health, being the third leading preventable cause of death in the United States. Several studies have been conducted to understand the etiology of high-risk drinking and to design prevention strategies to reduce unhealthy alcohol-consumption and related problems, but there are still major gaps in identifying and investigating the key components that affect the consumption patterns during the drinking event.

In this case-control study, a clinical protocol was developed in which misusers of alcohol were asked to sign a contract to be abstinent of alcohol prior to surgery. This protocol was associated with a reduction in hospital stay, fewer wound complications, decreased withdrawal, and reduced time lapse to adjuvant radiation therapy.

Drinking-related problems are increasing among Asian immigrants despite the popular perceptions of a “model minority.” Sociocultural factors may relate to differing drinking patterns among subsets of Asian American populations. This study explores the relationship between nationality and alcohol consumption among Chinese and Korean Americans, specifically in regards to acculturation and social networks.

The scientific discovery, development, and implementation of evidence-informed solutions for alleviating alcohol-related problems are inherently multisectoral, as they affect individuals, families, communities, and larger social systems. The advent of new technologies, research approaches, and intervention strategies has dramatically accelerated positive results in addressing such problems over the past 40 years. Still, alcohol misuse remains a significant global problem, and reducing and preventing its consequences is a Grand Challenge for Social Work.
