[Association between food intake and hyperuricemia in the elderly aged 18 years and above in China in 2018].

Objective: To explore the relationship between food intake and hyperuricemia in the elderly aged 18 years and above in China.

Methods: The present study used data from "China Health and Nutrition Survey" in 2018. Adults aged 18 years and above with complete questionnaires and anthropometric data were included in the analysis. Three consecutive 24 h dietary recalls method was used to collect dietary consumption data. Logistic regression model was applied to analyze the effect of food intake on hyperuricemia.

Results: The prevalence of hyperuricemia in adults in fifteen provinces of China was 12.63% in 2018. Increased intake of rice(OR=1.419, 95%CI 1.143-1.761, P<0.001), livestock meat(OR=1.332, 95%CI 1.082-1.641, P<0.001), and poultry(OR=1.268, 95%CI 1.031-1.560, P<0.001) in the daily diet would increase the risk of hyperuricemia; higher intake of fruit(OR=0.792, 95%CI 0.643-0.977, P<0.001) was associated with a lower risk of hyperuricemia, and the risk of hyperuricemia was reduced in the 2nd tertile of dairy intake compared with non-intake group(OR=0.721, 95%CI 0.541-0.961, P<0.001).

Conclusion: For patients with hyperuricemia or people at risk of hyperuricemia, adherence to a diet of reduced intake of rice, livestock meat and poultry, increased intake of fruits, and moderate intake of dairy products can lower the serum uric acid level as well as the risk of developing hyperuricemia.
