Objective: To assess the correlation between serum uric acid and insulin resistance in natural population of Beijing.
Methods: 1 056 people without-diabetes, 460 males and 596 females, aged 35-64 was selected from the natural population in Beijing using stratified-random sampling method. Serum uric acid, fasting blood glucose, insulin and other metabolic parameters were measured. The insulin activity index (IAI) was calculated to assess insulin resistance.
Results: The natural logarithm of IAI was decreased with the elevation of serum uric acid level (F = 47.884, P < 0.001). The prevalence of insulin resistance increased with the elevation of uric acid level, from 13.8% in quartile 1 to 33.9% in quartile 4. Compared to the quartile 1, the odds ratio (OR) of the quartile 2 for prevalence of insulin resistance was 1.935; the OR of the quartile 3 was 1.590; the OR of the quartile 4 was 2. 088. Uric acid was independently correlated with insulin resistance after adjustment for sex, age and main components of metabolic syndrome (MS).
Conclusion: Serum uric acid is correlated with insulin resistance in Beijing natural population after adjustment of sex, age, and the main components of MS.
