Life-time problem drinking and psychiatric co-morbidity among Ontario women

Women problem drinkers in the community, aged 15-64 years, with and without life-time psychiatric co-morbidity were compared to examine the association of this co-morbidity with alcohol consumption patterns, course and chronicity of problem drinking, treatment service utilization and other substance use and misuse. The women problem drinkers were also compared with non-problem drinkers on substance use patterns and utilization of services. The study employs data from the Mental Health Supplement to the Ontario Health Survey, a province-wide household population study. The University of Michigan Composite International Diagnostic Interview (UM-CIDI) was administered by trained lay interviewers and subsequently World Health Organization computer algorithms were used to generate DSM-III-R diagnoses based on the interview responses. Multiple logistic regression analysis indicated that psychiatric co-morbidity was associated with less education, earlier onset of problem drinking and one indicator of binge drinking. Co-morbidity also greatly increased the chances of women problem drinkers having sought mental health treatment. Women problem drinkers were significantly younger (about 7 years) than women in the general population, perhaps an indicator of an increased mortality rate.
