Serum uric acid: correlation with biological, clinical and behavioral factors in Japanese men

Abstract

Cross-sectional associations between biological, clinical and behavioral factors and serum uric acid (SUA) levels were examined in 2,438 Japanese male office workers aged 20 to 59 years in Osaka, Japan. Stepwise regression analysis for SUA was carried out for all persons and repeated excluding those under medication for hypertension, hyperuricemia or diabetes mellitus. The results were essentially the same without change in the sequence of the seven most important variables. When 150 men under medication were excluded, independent correlates with SUA levels were, in order of relative importance, history of gout, log triglyceride, creatinine, hemoglobin A1c (negative association), body mass index, total protein, alcohol intake, age (negative association), and total cholesterol. 32.7 percent of total variation in SUA was accounted for by these variables combined. Our data suggest that weight and serum lipids control and avoiding excessive drinking may be beneficial in the prevention of hyperuricemia.
