BackgroundTo study the relationship between hyperuricemia and cardiovascular diseases (CVDs) risk factors in a Chinese population.Material/MethodsData analyzed in this study were from the Chinese Hyperuricemia and Gout Database. Indicators of serum uric acid (SUA) level, height, weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), smoking status, alcohol consumption, blood glucose, cholesterol, and triglycerides were measured. T test, one-way analysis of variance, Pearson’s correlation, multivariate linear regression, and multivariate logistic regression were used.ResultsCompared with normouricemic men, hyperuricemic men had greater height (P<0.01), weight (P<0.001), body mass index (BMI) (P<0.001), SBP (P<0.01), DBP (P<0.001), cholesterol (P<0.01), and triglyceride (P<0.001). Compared with normouricemic women, hyperuricemic women were older (P<0.01) and had greater weight (P<0.05), BMI (P<0.01), SBP (P<0.01), DBP (P<0.05), glucose (P<0.05), and triglyceride (P<0.001). In men, an increase of 1 mg/dL in SUA was associated with a 0.279 kg/m2 increase in BMI (P<0.001), a 2.438 mg/dL increase in cholesterol (P<0.05), a 10.358 mg/dL increase in triglyceride (P<0.001), and a 3.1 mg/dL decrease in glucose (P<0.01). In women, an increase of 1 mg/dL SUA was associated with a 0.168 kg/m2 increase in BMI (P<0.01) and a 3.708 mg/dL increase in triglyceride (P<0.01). After adjustment, SUA was strongly associated with obesity and hyperlipidemia in both sexes.ConclusionsElevated serum uric acid concentration was strongly associated with obesity and hyperlipidemia in both men and women. These results indicated that, among hyperuricemia patients, we should pay more attention to the possibility of cardiovascular complications. These results might provide a novel target or a possible new treatment for cardiovascular diseases by lowering the level of serum uric acid.

The aim of this study was to explore the relationship between hyperuricemia and hematological indicators.Five hundred twenty-two male and 255 female subjects (18–90 years old) were recruited in the study. The level of serum uric acid (SUA), total white blood cell (WBC) count, red blood cell (RBC) count, hemoglobin, hematocrit, and platelet count was measured, computed, and analyzed. Pearson correlation coefficients, Student t-tests, multivariate linear regression models, and multivariate logistic regression models were performed to analyze the results.For men, WBC count (r = 0.13, P < 0.01), RBC count (r = 0.15, P < 0.001), and hemoglobin (r = 0.11, P < 0.05) were significantly correlated with SUA. For women, WBC count (r = 0.24, P < 0.001), RBC count (r = 0.31, P < 0.001), hemoglobin (r = 0.31, P < 0.001), and hematocrit (r = 0.29, P < 0.001) were significantly correlated with SUA. For men, WBC (P < 0.01) and RBC (P < 0.05) counts were significantly higher in patients with hyperuricemia than in normal subjects. For men, after adjustment for confounding factors, those in the fourth quartiles of WBC counts had 1.66-fold increased odds of hyperuricemia as compared with those in the reference group. For women, after adjustment, those in the second to fourth quartiles of WBC count, RBC count, hemoglobin, and hematocrit had increased the odds of hyperuricemia as compared with those in the reference groups.Our study showed significant relations between the level of SUA and WBC count, RBC count, hemoglobin, and hematocrit, which could be important biological markers of hyperuricemia.
