Addiction

Aims To examine: rates of young adult alcohol and drug use and alcohol problems; adolescent predictors of young adult alcohol problems; and correlations with young adult social, work, and recreational environments. Design Adolescents were longitudinally followed into young adulthood. Predictors were measured in grade 9 (av., age 15), and environmental correlates and outcomes in young adulthood (av., age 21). Setting Students recruited in Victoria, Australia in 2002, were resurveyed in 2010/11. Participants Analytic N = 2,309, 80% retention. Measurements Adolescent self-report predictors included past-month alcohol use. Young adults completed the Alcohol Use Disorders Identification Test (AUDIT) together with reports of environmental influences. Findings Comparisons to United States of America (U.S.) national school graduate samples revealed higher rates of alcohol, tobacco, and illicit drug use (other than cannabis) in Victoria. For example rates of past month use at age 21–22 were: alcohol 69.3% U.S. vs 84.9% (95% Confidence Interval [CI]) 81.3 – 88.6% Victoria; illicit drugs (other than cannabis) 8.8% vs 12.7%, CI 9.7 – 15.7%. AUDIT alcohol problems (scored 8+) were identified for 41.2%, CI 38.8 – 43.6% of young adults in Victoria. The likelihood of young adult alcohol problems was higher for frequent adolescent alcohol users, and those exposed to environments characterised by high alcohol use and problems in young adulthood. Conclusions High rates of alcohol problems are evident in over two in five Australian young adults and these problems appear to be influenced both by earlier patterns of adolescent alcohol use and by young adult social work, and recreational environments.
