Objective: To observe the relationship between serum uric acid and brachial ankle pulse wave velocity (ba-PWV) in Beijing community individuals.
Methods: This epidemiological survey was performed in residents of two communities from Shijingshan District in Beijing from 2007 to 2008. Cardiovascular risk factors and ba-PWV were measured. Two thousand five hundred and forty three individuals with both ba-PWV and serum uric acid measurements were included. Ba-PWV ≥ 1400 cm/s was defined as abnormal. The individuals were divided into four groups (Q1, Q2, Q3 and Q4 group) according to the gender-specific quartiles of serum uric acid. Univariate logistic regression was used to evaluate the relation between various cardiovascular risk factors and ba-PWV abnormality. Multivariate logistic regression was used to evaluate the relation between serum uric acid and ba-PWV abnormality after adjusting for other cardiovascular risk factors.
Results: Body mass index, triglyeride and prevalence of hypertension increased with increasing levels of serum uric acid (all P < 0.01). Univariate logistic regression analysis showed that age, gender, smoking, hypertension, systolic blood pressure, diastolic blood pressure, diabetes, body mass index, total cholesterol, triglyeride and estimated glomerular filtration rate were related with ba-PWV abnormality (all P < 0.01). Compared with Q1 group, ba-PWV abnormality OR value of Q4 group was 1.73 (95%CI: 1.34 - 2.22, P < 0.01). Multivariate logistic regression revealed that ba-PWV abnormality OR value of Q4 group was 1.66 (95%CI: 1.16 - 2.37, P < 0.01 ) after adjusting for age, gender, smoking, hypertension, systolic blood pressure, diastolic blood pressure, diabetes, body mass index, total cholesterol, triglyeride and estimated glomerular filtration rate when compared with Q1 group and OR values were 1.55 (95%CI: 0.88 - 2.74, P > 0.05) and 1.65 (95%CI: 1.04 - 2.64, P < 0.05) in male and female respectively.
Conclusion: Increased serum uric acid was independently associated with ba-PWV abnormality in Beijing community residents.
