Substance Use and Work Disabilities among a General Population

Using data derived from a representative survey of 869 Ontario adults, we examined the association between work disabilities and substance use, i.e., drinking, alcohol problems, sleeping pills, and tranquilizers. Overall, we found a significant association between substance use and disability. For alcohol problems, we found that those with moderate limitations reported the greatest number of problems, holding constant age, gender, income, and frequency of drinking. For the use of sleeping pills and especially tranquilizers, we found a strong positive relationship to limitation status. A number of significant interactions involving tranquilizer use showed that two groups, females with total limitations and those aged over 40 years with sensory disabilities, reported exceptionally high rates of tranquilizer use.
