Association between dietary coenzyme Q10 intake and hyperuricemia in Chinese adults: a nationwide cross-sectional study

Abstract

Background: The association of food-sourced Coenzyme Q10(CoQ10) intake with hyperuricemia (HUA) remains unclear. We aimed to investigate the association between dietary CoQ10 intake and HUA among Chinese adults. Methods: A total of 7953 Chinese adults from the 2009 China Health and Nutrition Survey (CHNS) were included in the present cross-sectional. Dietary CoQ10 was assessed by 3 consecutive 24-h dietary recall interviews combined with a household food inventory. Multivariable logistic regression models and restricted cubic spline models were used to explore the associations between dietary CoQ10 and HUA. Results: In an adjusted logistic regression model, the multivariable odds ratio (OR) and 95% confidence interval (CI) for HUA in the highest versus the lowest quartile of total, animal-based, and plant-based CoQ10 intake were 1.40 (95% CI: 1.15 to 1.70), 1.46 (95% CI: 1.20 to 1.78), and 0.80 (95% CI: 0.65 to 0.97), respectively. Dose-response analyses revealed similar linear patterns, with the exception of plant-derived CoQ10, which did not reach statistical significance (p for nonlinearity = 0.09). In stratified analysis, there were no significant interactions between sex, age, BMI, smoking status, drinking status and total dietary CoQ10 intake in relation to the HUA (All p for interaction > 0.05). Conclusions: Our study documented a novel positive association between total dietary CoQ10 intake and HUA, with similar trends for animal-derived CoQ10 and an inverse trend for plant-derived CoQ10.
