Summary

Alcohol intolerance, identified by the Ethanol Patch Test, is common in dental students. Those with alcohol intolerance were less likely to be problem drinkers, but some still drank excessively.

Area of Science:

  • Biochemistry
  • Genetics
  • Public Health

Context:

  • Alcohol metabolism and its genetic variations are crucial in understanding drinking behaviors.
  • Aldehyde dehydrogenase 2 (ALDH2) deficiency, a common genetic trait, affects alcohol metabolism and flushing response.
  • Assessing drinking habits and alcohol intolerance in university students provides insights into potential public health issues.

Purpose:

  • To investigate the relationship between alcohol intolerance, assessed via the Ethanol Patch Test and Tokyo-University ALDH2-Phenotype Screening Test (TAST), and problem drinking behaviors using the Kurihama Alcoholism Screening Test (KAST) and Adolescent Alcohol Involvement Scale (AAIS).
  • To determine the prevalence of ALDH2 deficiency in a cohort of dental students.
  • To explore correlations between genetic alcohol intolerance and self-reported drinking patterns.

Summary:

  • A study involving 232 dental students utilized the Ethanol Patch Test, TAST, KAST, and AAIS to assess drinking habits and alcohol intolerance.
  • The Ethanol Patch Test and TAST indicated significant prevalence of ALDH2 deficiency (alcohol intolerance) among students (approx. 44.5-51.9%).
  • While Patch test-negatives showed higher KAST-defined problem drinking ratios, suggesting a predisposition to alcohol dependence, some alcohol-intolerant students also reported excessive drinking.

Impact:

  • The findings suggest that individuals with alcohol intolerance may be less prone to developing alcohol dependence, contrary to some expectations.
  • Despite genetic predispositions to avoid alcohol due to intolerance, a subset of these students engages in excessive alcohol consumption.
  • This highlights the complex interplay between genetic factors, social influences, and individual drinking behaviors, necessitating targeted interventions for at-risk student populations.
