TABLE 8.
Weighted odds ratios (95% confidence intervals) for insulin resistance (HOMA-IR) of participants across quartiles of serum uric acid, stratified analysis by menopause (Pre-menopausal women = 1,245; Post-menopausal women = 1,122).

aCalculated using binary logistic regression.
†Pre-menopausal women: Q1 (uric acid ≤ 226.00 μmol/L), Q2 (226.00 < uric acid ≤ 267.70 μmol/L), Q3 (267.70 < uric acid ≤ 303.30 μmol/L), and Q4 (uric acid > 303.30 μmol/L).
Post-menopausal women: Q1 (uric acid ≤ 249.80 μmol/L), Q2 (249.80 < uric acid ≤ 291.50 μmol/L), Q3 (291.50 < uric acid ≤ 339.00 μmol/L), and Q4 (uric acid > 339.00 μmol/L).
Model 1 adjusted for race.
Model 2 adjusted for race, body mass index, waist circumference, drinking status, education level, hypertension, serum triglyceride, total cholesterol, and urate-lowering therapy.
