Serum Uric Acid Level Associated With Metabolic Syndrome

Blood pressure, fasting plasma glucose, insulin, lipid profiles, uric acid, and anthropometric measures were determined, and body composition was assessed by using bioelectrical impedance analysis (BIA). Homeostasis Model Assessment (HOMA) was used for the assessment of insulin resistance.

Total cholesterol (TC) and TG were determined enzymatically using Parsazmun kits (Tehran, Iran). High density lipoprotein cholesterol (HDL-C) was measured similarly after precipitation with magnesium phosphotungstate. LDL-cholesterol was calculated using Friedewald’s formula. Fasting plasma glucose (FPG was measured using the glucose oxidase method, and immunoreactive insulin (IRI) was measured by radioimmunoassay.

After adjustment for confounding factors, serum uric acid was statistically significantly higher in MetS group at 5.70 ± 1.62 mg/dL than in non-MetS group 4.97 ± 1.30 mg/dL. Subjects in the MetS group had higher anthropometric and blood pressure measurements, body mass index (BMI), lean body mass (LBM), body fat mass (BFM), FPG, insulin, HOMA index, TG, TC, LDL, and lower HDL levels than the subjects in the non-MetS group.

The authors concluded that serum uric acid had independent association with MetS components, and increased the risk of MetS by nearly two-fold. The findings propose that uric acid can be considered as a component of MetS. The study was published on September 15, 2015, in the Journal of Diabetes & Metabolic Disorders.
