Relationships of alcohol use and alcohol problems to probable anxiety and mood disorder

摘要

We examine the effects of alcohol consumption and problem drinking on probable anxiety and mood disorder (AMD). Data were taken from the 2000-2006 CAMH Monitor (N = 15,653) general population survey of Ontario adults. Scoring 4+ on the 12-item General Health Questionnaire defined probable AMD, as suggested by recent research. Logistic regression showed that respondents with alcohol problems had significantly increased odds of probable AMD, but those reporting moderate daily alcohol consumption (up to 2 drinks) had decreased odds of probable AMD compared to abstainers. These data replicate other recent research in suggesting that the relationship between alcohol and adverse psychological states, such as psychological distress and probable anxiety and mood disorder, may not be monotonic. Several ways in which selection bias could account for these findings are discussed, as well as other possible causative mechanisms.
