Alcohol-use patterns through medical school. A longitudinal study of one class

Area of Science:

• Medical Education
• Psychiatry
• Public Health

Background:

• Alcohol consumption is prevalent among medical students.
• Understanding alcohol use patterns is crucial for targeted interventions.

Purpose of the Study:

• To examine alcohol use trajectories in medical students over four years.
• To identify the prevalence of excessive drinking and alcohol abuse.
• To explore the relationship between alcohol use and academic performance.

Main Methods:

• Longitudinal assessment of alcohol use in a single medical school class.
• Repeated measurements from matriculation to near graduation.
• Application of Research Diagnostic Criteria for alcohol abuse.
• Analysis of academic performance metrics (grades, board exam scores).

Main Results:

• Male students initially drank more but reduced intake over time, converging with female students.
• 11% experienced excessive drinking; 18% met alcohol abuse criteria in the first two years.
• Excessive drinkers were more likely to meet abuse criteria than vice versa.
• Alcohol abusers demonstrated better academic performance (first-year grades, NBME Part I scores).

Conclusions:

• Alcohol use patterns evolve during medical school, with initial gender differences diminishing.
• A significant minority of students engage in problematic alcohol use.
• Alcohol abuse may be associated with higher academic achievement in some medical students.
• Findings inform the development of prevention and intervention programs for medical schools.
