title: Serum concentration of uric acid associated with prehypertension among Chinese population.
abstract: We evaluated the association between serum uric acid (SUA) levels and prehypertension in a Chinese population. A cross-sectional study was performed during 2008 to 2010, and a total of 11199 participants without hypertension or other cardiovascular diseases (CADs), aged ≥35 years, were available for analysis. After adjusting for age, alcohol consumption, smoking status, body mass index, diabetes, total cholesterol, triglycerides, serum creatinine, the odds ratios (ORs) and 95% confidence intervals (CIs) of the prehypertension from the lowest (referent) to the highest levels of SUA were 1.00 (95% CI, 0.91-1.10), 1.12 (95% CI, 1.03-1.21), 1.17 (95% CI, 1.09-1.27), and 1.25 (95% CI, 1.13-1.39; linear trend P = .002). This association persisted in subgroup analysis by gender and was also consistent with separate analysis by classification of age, smoking status, alcohol usage, overweight, and diabetes mellitus. Independent of other cardiovascular risk factors, higher SUA levels are positively associated with prehypertension in a Chinese population without hypertension and CADs. Prospective trials should evaluate interventions that lower the SUA levels.
