摘要


Background and Objectives: The association of dietary and nutritional factors with hyperuricemia and gout is well-known in Western populations. The present study aimed to examine the association of dietary and nutritional factors with hyperuricemia among Korean adults. Methods and Study Design: This cross-sectional study included 10,175 participants from the seventh Korean National Health and Nutrition Examination Survey 2016-2017. Dietary information was collected using a single 24-hour recall method, and nutritional information was derived from the 9th Korean Food Composition Table. The associations between serum uric acid and intake of meat, seafoods, nuts, and legumes, sugar-sweetened products, dairy products, alcohol, sodium, vitamin A, vitamin B1, vitamin C, and dietary fiber were analyzed using linear regression analysis adjusting for confounding variables. The association with hyperuricemia was analyzed using logistic regression analysis. All analyses were weighted by the sampling design. Results: Alcohol intake was associated with serum uric acid in both men and women. In men, the highest quartile of alcohol intake was associated with a 1.5-times higher prevalence of hyperuricemia (odds ratio [OR] 1.5, 95% confidence interval [CI] 1.16-1.95), while vitamin C and dietary fiber intakes were found to be inversely associated with hyperuricemia. For vitamin C and dietary fiber intake, the ORs for a quartile increase were 0.93 (95% CI 0.86-0.99) and 0.92 (95% CI 0.85-0.99), respectively. Conclusions: The associations between vitamin C, dietary fiber and alcohol intakes and hyperuricemia in men support the Dietary Approach to Stop Hypertension (DASH)-based approach and attention to alcohol intake for managing hyperuricemia in Korean men.
