Resistin/uric acid index as a marker of metabolic syndrome in females with obesity.

Abstract

The resistin/uric index has been considered a prognostic factor for identifying young people with obesity. Obesity and Metabolic Syndrome (MS) are an important health problem in females. The objective of this work was to evaluate the relationship of resistin/acid uric index with Metabolic Syndrome on Caucasian females with obesity. We conducted a cross sectional study in 571 females with obesity. Measurements of anthropometric parameters, blood pressure, fasting blood glucose, insulin concentration, insulin resistance (HOMA-IR), lipid profile, C reactive protein, uric acid, resistin and prevalence of Metabolic Syndrome were determined. The resistin/uric acid index was calculated. In total, 249 subjects had MS (43.6%). We detected higher levels in the following parameters (Delta; p values); waist circumference (3.1 ± 0.5 cm; p = 0.04), systolic blood pressure (5.3 ± 3.6 mmHg; p = 0.01), diastolic blood pressure (2.3 ± 0.4 mmHg; p = 0.02), glucose levels (7.5 ± 0.9 mg/dL; p = 0.01), insulin levels (2.5 ± 0.3 UI/L; p = 0.02), HOMA-IR (0.7 ± 0.2 units; p = 0.03), uric acid levels (0.9 ± 0.2 mg/dl; p = 0.01), resistin levels (4.1 ± 0.4 ng/dl; p = 0.01) and resistin/uric acid index (0.61 ± 0.01 mg/dl; p = 0.02) in subjects of the high resistin/uric acid index group than low index group. Logistic regression analysis reported a high percentage of hyperglycemia (OR = 1.77, 95% CI = 1.10-2.92; p = 0.02), hypertension (OR = 1.91, 95% CI = 1.36-3.01; p = 0.01), central obesity (OR = 1.48, 95% CI = 1.15-1.84; p = 0.03) and metabolic syndrome percentage (OR = 1.71, 95% CI = 1.22-2.69; p = 0.02) in high resistin/uric acid index group. Resistin/uric acid index is related with Metabolic syndrome (MS) risk and criteria of it in a population of Caucasian females with obesity and this index is a correlated with glucose levels, insulin levels and insulin resistance (HOMA-IR).
