New biomarkers for alcohol intake were identified using metabolomic profiles. These findings in large cohorts suggest potential for improved detection of moderate-to-heavy alcohol consumption in future health studies.
Area of Science:
- Metabolomics
- Biomarker Discovery
- Alcohol Research
Background:
- Alcohol consumption is a leading global risk factor for disease.
- Mechanisms of alcohol-induced damage and optimal biomarkers remain poorly understood.
Purpose of the Study:
- To investigate metabolite concentration differences related to alcohol intake.
- To identify and validate biomarkers for distinguishing light drinkers from moderate-to-heavy drinkers.
Main Methods:
- Analysis of metabolite concentrations in 2090 individuals (KORA F4).
- Logistic regression adjusted for covariates (age, BMI, smoking, lipids).
- Replication in KORA F3 and TwinsUK cohorts.
Main Results:
- Identified 40/18 significant metabolites in males/females differentiating light drinkers (LD) from moderate-to-heavy drinkers (MHD).
- Metabolite profiles achieved 0.812/0.679 AUC, indicating moderate-to-high accuracy in discrimination.
- Replicated alcohol-related metabolites across independent cohorts.
Conclusions:
- Metabolomic profiles involving phosphatidylcholines, ether lipids, and sphingolipids show promise as novel biomarkers for excess alcohol intake.
- These findings support potential applications in future epidemiological and clinical studies for assessing alcohol consumption.
