Socio-demographic differences in alcohol-related work impairment.

In Norway, the risk of alcohol-related work impairment for employees in the highest education category is approximately twice that of employees with secondary education or less. Except for employees in the lowest income category, who had a higher risk than those in the middle-income categories, higher income is associated with increased risk of work impairment. Being younger and male are also associated with increased risk of alcohol-related work impairment.
