BACKGROUND AND OBJECTIVES: The relationship between vitamin C intake and hyperuricemia among the general US adult population has seldom been reported; thus, the present study examined the associations of total vitamin C (dietary vitamin C plus supplementary vitamin C) and dietary vitamin C intake with the risk of hyperuricemia.

METHODS AND STUDY DESIGN: Pooled data from three 2-year cycles (2007-2012) of the cross-sectional National Health and Nutrition Examination Survey were used in the present study. Dietary intake data were extracted from two 24-hour dietary recall interviews. Logistic regression models were used to determine the associations between vitamin C intake and hyperuricemia risk.

RESULTS: A total of 14885 adults aged 20 years or older (7269 men and 7616 women) were registered in the present study. The prevalence of hyperuricemia was 19.1%. Based on the lowest quartile of dietary vitamin C intake, multivariate adjusted odds ratios with 95% confidence intervals of hyperuricemia for quartiles 2-4 were 0.84 (0.74-0.95), 0.83 (0.73-0.94), and 0.72 (0.63-0.82), and those for total vitamin C intake were 0.87 (0.77-0.99), 0.85 (0.75-0.96), and 0.66 (0.58-0.76). Inverse associations between vitamin C intake and hyperuricemia were discovered in both men and women, even with or without covariate adjustments.

CONCLUSIONS: Total vitamin C and dietary vitamin C intake are inversely associated with hyperuricemia in the general US adult population.
