Serum uric acid and its relation to cardiovascular disease risk factors in children and young adults from a biracial community: the Bogalusa Heart Study

Abstract

The distribution of serum uric acid and its relationship with cardiovascular risk variables have been studied in 3983 children and young adults, aged 5 to 26 years, drawn from a biracial (black and white) population. For two age groups, 5 to 11 years and 19 to 26 years, white subjects had significantly higher uric acid levels than black subjects, (4.02 mg/dl vs 3.57 mg/dl, p less than 0.0001, and 5.50 mg/dl vs 5.18 mg/dl, p less than 0.0001, respectively). Men in the 19 to 26 years age group had a significantly higher uric acid level than women (6.49 mg/dl vs 4.20 mg/dl, p less than 0.0001). White children and young adults were twice as likely to have levels above clinical limits than blacks, and males more likely to have hyperuricemia than females. Parents with a history of myocardial infarction were more likely to have children with hyperuricemia. Children and young adults with hyperuricemia had significantly higher plasma glucose (p less than 0.01) and insulin (p less than 0.001) levels, total cholesterol level (p less than 0.05), and serum triglyceride (p less than 0.0001), very-low-density lipoprotein cholesterol (p less than 0.01), low-density lipoprotein cholesterol (p less than 0.001), and total protein (p less than 0.0001) levels than subjects without hyperuricemia; high-density lipoprotein cholesterol level was significantly lower (p less than 0.0001) in subjects with hyperuricemia than in those without it.(ABSTRACT TRUNCATED AT 250 WORDS)
