Early alcohol experiences and adolescent mental health: A population-based study in Taiwan

In this study, we examine whether adolescent emotional and behavior problems vary by history of early alcohol experiences. A national sample of 6974 alcohol-naïve and 4337 alcohol-experienced youths aged 15–18 years were identified within the 2004 National Survey of Illegal Drug Use among Adolescents in Taiwan. Four alcohol experience groups were created based on recency and frequency of alcohol use: (1) naïve; never drank alcohol, (2) trial use; first and only consumption of alcohol occurred more than 6 months preceding the assessment, (3) past use; alcohol used on more than one occasion but had not had a drink in the 6 months prior to the assessment, and (4) current use; consumed alcohol more than once and drank within the 6 months preceding the interview. A Chinese adaptation of the Youth Self-Report (YSR) assessed eight behavior syndromes: withdrawn, anxious/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, and aggressive behavior. Multivariate response models (GLM/GEE) were used to examine the relationship of alcohol experiences with emotional and behavior problems. Alcohol-using youth were more likely to experience several specific emotional or behavioral syndromes than their alcohol-naïve counterparts. For example, youth with a history of alcohol use had an estimated 30–60% increase in the odds of experiencing items within the aggressive behavior syndrome as compared with alcohol-naïve youth. The type of early alcohol involvement in adolescence may exert differential effects on emotions and behaviors expressed across and within syndromes; these may warrant distinctions in informing etiological research and preventive efforts.
