This study investigated consumption patterns, alcohol-related problems and predictors of problematic drinking among older adolescents. Two-hundred eighty older adolescents (148 males, mean +/- SD age = 18.5 [1.8] years) treated in two Emergency Departments (ED) completed the Alcohol Use Disorders Inventory Test (AUDIT) to identify problem drinkers. Logistic regression was used to determine predictors of problem drinker status. Higher rates of problem drinking were found among participants who were treated for physical assaults or for acute alcohol intoxication than were found among participants treated for medical illness. Being alcohol-positive in the ED, increasing frequency of drunkenness, and being treated for physical assault were predictive of problematic drinking after controlling for demographic variables. In conclusion, older adolescents who present for treatment of an assault-related injury or acute alcohol intoxication, who are alcohol-positive in the ED, and who report getting intoxicated once a month or more are likely to have a severe drinking problem.
[Show abstract][Hide abstract] ABSTRACT: Adolescents using alcohol and drugs are at higher risk for assaultive behaviors. We examined adolescents aged 10 to 20 years who were hospitalized for assault injuries between July 1995 and December 1998 in Maryland to determine the demographic and injury-related predictors of the presence of drug/alcohol use among adolescents, and to estimate the presence of drug/alcohol use among adolescents with undetermined drug and/or alcohol use.
Patient records for adolescents were selected from 2189 discharges from the Maryland Trauma Registry and 1625 discharges from the Maryland Hospital Discharge data system. Three discrete groups of adolescents were identified: (1) those on the Trauma Registry and in the Hospital Discharge data system (N = 1197), (2) only those on the Trauma Registry (N = 992), or (3) only those in the Hospital Discharge data system (N = 428). Multiple logistic regression was performed to determine the predictors of the presence of drug/alcohol use among adolescents in the Trauma Registry. These models were then used to estimate the presence of drug/alcohol use among adolescents with undetermined drug and/or alcohol use.
Age, sex, mechanism of injury, day of hospital admittance, and time of day were significant predictors of alcohol/drug use. The proportion of predicted alcohol/drug involved hospitalized cases varied from 54% to 66%.
Our methodology and findings contribute to the understanding of the epidemiology of assaultive behaviors and the role of alcohol/drug use in injury among adolescents.

[Show abstract][Hide abstract] ABSTRACT: To identify population-based clinical and demographic correlates of alcohol use dimensions.
Using data from a population-based sample of Great Britain (n = 7849), structural equation modelling (SEM) was used to identify associations between demographic and clinical variables and two competing dimensional models of the Alcohol Use Disorders Identification Test (AUDIT).
A two-factor SEM fit best. In this model, Factor 1, alcohol consumption, was associated with male sex, younger age, lower educational attainment, generalized anxiety disorder (GAD) and suicide attempts. Factor 2, alcohol-related problems, was associated with the demographic variables (to a lesser extent) and to a wider range of clinical variables, including depressive episode, GAD, mixed anxiety and depressive disorder, obsessive compulsive disorder, phobia, suicidal thoughts and suicide attempts. The one-factor SEM was associated with demographic and all assessed clinical correlates; however, this model did not fit the data well.
Two main conclusions justify the two-factor approach to alcohol use classification. First, the model fit was considerably superior and, second, the dimensions of alcohol consumption and alcohol-related problems vary considerably in their associations with measures of demographic and clinical risk. A one-factor representation of alcohol use, for instance, would fail to recognize that measures of affective/anxiety disorders are more consistently related to alcohol-related problems than to alcohol consumption. It is suggested therefore that to fully understand the complexity of alcohol use behaviour and its associated risk, future research should acknowledge the basic underlying dimensional structure of the construct.
