Abstract
Background: This study aimed to analyze the association between the prevalence of hyperuricemia and obesity in Korean adults.
Methods: The participants included 5,922 adults from the 2018 Korea National Health and Nutrition Examination Survey. We examined the relationship between obesity status and serum uric acid levels using a chi-square test and multiple logistic regression.
Results: There was an increase in the prevalence of hyperuricemia with higher body mass index (P<0.001 and P=0.003, respectively). Both male and female in a higher obesity class also had a higher odds ratio for the prevalence of hyperuricemia (P<0.001). This trend remained consistent after adjusting for all confounding factors. The obesity class III group was found to be associated with the highest risk of hyperuricemia.
Conclusion: In this study, we found that hyperuricemia was significantly associated with obesity in Korean adults. In a clinical setting, this finding presents objective data for more aggressive management and ultimate prevention of obesity.
