Objective To investigate the association of serum uric acid (SUA) with arterial stiffness assessed by cardio-ankle vascular index (CAVI). Methods We analyzed the cross-sectional data from 27,360 healthy Japanese subjects (12,910 males and 14,450 females) aged between 20 and 74 years without a past history of heart disease, stroke, hypertension, diabetes, nephritis or gout. We investigated whether SUA was independently associated with CAVI in a gender-specific manner. Results BMI, CAVI, systolic/diastolic BP, GOT, GPT, γ-GTP, triglyceride (TG), creatinine and SUA were higher and HDL-C was lower in males than in females. Next, they were stratified by SUA into 3 groups: lower tertile (T1), middle tertile (T2) and upper tertile (T3) and by gender. CAVI increased progressive with increasing SUA tertile, after adjusting for age, BMI and systolic BP (sBP) identified in multiple regression analysis for CAVI. Multivariate analysis showed that the odds ratios (95% CI) relative to T1 for high CAVI (≥90 th percentile) were 1.233 (0.928–1.638) in T2 and 1.352 (1.031–1.773) in T3 for males, and 1.133 (0.984–1.303) in T2 and 1.361 (1.098–1.687) in T3 for females, after adjusting for confounders. Furthermore, increase in adjusted CAVI was observed in a lower SUA range in females compared to that observed in males. Conclusion We demonstrated an independent correlation between SUA and CAVI, and observed gender difference in the SUA range for increase in CAVI. These results may suggest the need to set different target SUA levels for men and women in anti-hyperuricemic treatment for atherosclerosis prevention. [ABSTRACT FROM AUTHOR]
