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

Abstract

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.
