A follow-up survey of alcohol consumption and knowledge in medical students.

We surveyed a medical school's students' drinking habits and knowledge 12 years after a previous survey. In this current survey from two academic years, final year students drank less than second year students did. Women in their second year drank as much as men. Overall, 28% of students drank more than the safe limits; 27% of students were problem drinkers, as measured by the CAGE questionnaire, and 52%, as measured by the AUDIT questionnaire. The proportion of students not drinking any alcohol rose from 6% in the previous survey to 27% in the current survey, possibly due to context and demographic changes. In spite of this difference, there have been no statistically significant reductions in either unsafe drinking levels or CAGE scores over 12 years. A third of students overestimated the safe levels of drinking. All medical schools should write and implement an alcohol policy.
