ABSTRACT In this commentary, we describe the use of a 5/4 drink summary measure of heavy episodic alcohol consumption, or "binge" drinking, in survey research and its usefulness for preventing negative alcohol-related consequences. Data from 4 nationally representative surveys of more than 50,000 college students are utilized to examine the utility of this measure in comparison with alternative cut-points. Our analysis demonstrates that while higher drink threshold measures incrementally improve the ability to identify correctly students who experience harms or who meet DSM-IV diagnostic criteria of alcohol abuse and dependence, they capture only a small proportion of those college students experiencing harms. We conclude that the selection of a measurement tool should be consistent with the purpose for which it is to be used. The 5/4 measure of binge drinking provides a valuable means for understanding and preventing alcohol-related harms in a college population and can be utilized as a screen to identify students who may need additional clinical assessment for intervention.

    ABSTRACT: Background Campus police and security personnel are often the first to respond to alcohol-related incidents on campus. The purpose of this study is to examine how campus law enforcement and security respond to alcohol-related incidents, and how consequences and communication differ based on characteristics of the incident.Methods Directors of campus police/security from 343 colleges across the United States completed a survey regarding usual practice following serious, underage, and less serious alcohol incidents on and off campus.ResultsCampus law enforcement and security most commonly reported contacting campus officials. A minority reported issuing citations and referring students to the health center. Enforcement actions were more commonly reported for serious and underage incidents than for less serious incidents. Large (vs. small) colleges, public (vs. private) colleges, and those located in small (vs. large) towns more consistently reported taking actions against drinkers.Conclusions Understanding how campus police and security respond to alcohol-related incidents is essential for reducing alcohol-related problems on college campuses.

    ABSTRACT: The main objective of this study is to evaluate the effect of heavy drinking on alcohol-related injuries. We carried out an open cohort study among university students in Spain (n=1,382). Heavy drinking and alcohol-related injuries were measured by administrating AUDIT questionnaires to every participant at the ages of 18, 20, 22 and 24. For data analysis we used a Multilevel Logistic Regression for repeated measures adjusting for consumption of alcohol and cannabis. The response rate at the beginning of the study was 99.6% (1,369 students). The incidence rate of alcohol-related injuries was 3.2 per 100 students year. After adjusting for alcohol consumption and cannabis use, the multivariate model revealed that a high frequency of heavy drinking was a risk factor for alcohol-related injuries (Odds Ratio=3.89 [95%CI: 2.16 - 6.99]). The proportion of alcohol-related injuries in exposed subjects attributable to heavy drinking was 59.78% [95%CI: 32.75 - 75.94] while the population attributable fraction was 45.48% [95%CI: 24.91 - 57.77]. We can conclude that heavy drinking leads to an increase of alcohol-related injuries. This shows a new dimension on the consequences of this public concern already related with a variety of health and social problems. Furthermore, our results allow us to suggest that about half of alcohol-related injuries could be avoided by removing this consumption pattern.

    ABSTRACT: Objetivo El objetivo principal del estudio es evaluar el efecto del consumo intensivo de alcohol sobre las lesiones relacionadas con esta droga. Material y métodos Se ha realizado un estudio de cohorte abierta entre universitarios en España (n = 1.382). El consumo intensivo y las lesiones relacionadas con el alcohol se midieron mediante la administración del cuestionario AUDIT a cada uno de los participantes a las edades de 18, 20, 22 y 24 años. Para analizar los datos se utilizó la Regresión Logística Multinivel para medidas repetidas ajustando por consumo de alcohol y de cannabis. Resultados La tasa de respuesta al comienzo del estudio fue 99,6% (1.369 estudiantes). La tasa de incidencia de lesiones relacionadas con el alcohol fue de 3,2 por 100 estudiantes año-1. Tras ajustar por consumo de alcohol y de cannabis, el modelo multivariante revela que la alta frecuencia de consumo intensivo fue un factor de riesgo para las lesiones relacionadas con el alcohol (Odds Ratio = 3,89[95%CI:2,16 – 6,99]). La proporción de lesiones relacionadas con el alcohol en expuestos atribuible al consumo intensivo fue 59.78% [95%CI: 32.75 – 75.94] mientras que la fracción atribuible poblacional fue 45.48% [95%CI: 24.91 – 57.77]. Conclusión Podemos concluir que el consumo intensivo conduce a un aumento de las lesiones relacionadas con el alcohol. Esto muestra una nueva dimensión de las consecuencias de esta preocupación social que ya se ha relacionado con variedad de problemas sociales y de salud. Además los resultados nos permiten sugerir que aproximadamente la mitad de las lesiones relacionadas con el alcohol podrían evitarse eliminando este patrón de consumo.
