Relationship between the flushing response and drinking behavior among Japanese high school students

Area of Science:

• Physiology
• Behavioral Science
• Genetics

Background:

• The alcohol flush reaction is a common genetic trait in East Asian populations.
• Understanding the relationship between physiological responses to alcohol and drinking behaviors is crucial for public health.
• Previous research suggests a potential link between the flushing response and reduced alcohol intake.

Purpose of the Study:

• To investigate whether the alcohol flush reaction (AFR) influences drinking behavior in Japanese adolescents.
• To determine if AFR acts as a deterrent to alcohol consumption frequency and quantity.

Main Methods:

• A cross-sectional survey was conducted on 932 Japanese high school students.
• Participants were categorized as flushers or nonflushers using the ethanol patch test.
• The Adolescent Alcohol Involvement Scale (AAIS) was administered to assess drinking patterns.

Main Results:

• Flushers (36.3%) reported significantly lower frequency and amount of alcohol consumption compared to nonflushers (63.7%).
• Despite reduced consumption, flushers and nonflushers shared similar drinking partners and motivations.
• Total AAIS scores did not significantly differ between flushers and nonflushers, indicating similar overall involvement.

Conclusions:

• The alcohol flush reaction is associated with reduced alcohol consumption in Japanese adolescents.
• Many flushers continue to drink alcohol despite experiencing discomfort, highlighting a need for targeted health education.
• Further education on the risks of adolescent alcohol consumption is necessary for this demographic.
