Abstract

Background
Coffee is one of the most commonly consumed beverages in the world. There is evidence that the consumption of coffee has a strong influence on health outcomes. However, the relationship between coffee consumption and serum uric acid in the Korean population is unclear. In this study, we investigated the relationship between coffee consumption and serum uric acid levels in Korean adults.
Methods
This study included 2,966 adults aged ≥19 years who participated in the Korea National Health and Nutrition Examination Survey 2016. The participants were divided into four groups according to the amount of coffee consumed and serum uric acid level. Linear regression analysis was used to analyze the relationship between coffee consumption and serum uric acid level.
Results
Serum uric acid level increased with increasing coffee consumption (P<0.001). After adjusting for all confounding factors, serum uric acid level was higher in the groups that consumed coffee daily, at more than four teaspoons, than in the groups that did not consume coffee (P<0.001).
Conclusion
The findings of this study suggest that coffee consumption has a positive relationship with serum uric acid level.
