Differences in the Association Between Alcoholic Beverage Type and Serum Urate Levels Using Standardized Ethanol...

Area of Science:

• Metabolic Health
• Nutritional Epidemiology
• Clinical Biochemistry

Background:

• Serum urate levels are associated with alcohol consumption, but previous studies lacked standardized ethanol intake units and evaluated limited beverage types.
• Understanding the differential impact of various alcoholic beverages on serum urate is crucial for managing hyperuricemia.

Purpose of the Study:

• To investigate the association between serum urate levels and consumption of different alcoholic beverages after standardizing for ethanol content.
• To identify specific alcoholic beverages that may influence serum urate levels differently.

Main Methods:

• Retrospective cross-sectional study using medical checkup data from 78,153 Japanese adults (2012-2021).
• Alcohol intake was standardized to 1 standard drink (20g ethanol).
• Multivariable linear regression with interaction terms analyzed associations between serum urate and dominant alcoholic beverage type (beer, sake, wine, whiskey).

Main Results:

• Higher beer consumption was consistently associated with elevated serum urate levels in both men and women.
• Wine consumption showed a moderate increase in serum urate, whereas sake consumption had a modest, non-significant association.
• Different patterns in serum urate levels were observed based on the dominant alcoholic beverage consumed, even with standardized ethanol intake.

Conclusions:

• The type of alcoholic beverage consumed, not just ethanol content, influences serum urate levels.
• Beer consumption is significantly linked to higher serum urate, highlighting its potential role in hyperuricemia development.
• Alcoholic beverage type should be considered alongside ethanol content when assessing hyperuricemia risk.
