Serum uric acid is independently associated with metabolic syndrome and systemic hypertension in women from northeast Brazil

Hyperuricemia (HU) has been associated with cardiovascular risk and metabolic syndrome (MS) worldwide. However, inconsistencies about this relation are still reported, and it is not clear whether hyperuricemia is an independent risk factor for MS. The aim of this study was to determine hyperuricemia associations with systemic hypertension and MS in women from northeast Brazil. The study included 301 women. Hyperuricemia was considered for serum uric acid (SUA) >= 6 mg/dL. Insulin resistance (IR) was measured by TyG index (TyG >= 4.55). Fisher test and Multivariate logistic regression analyses estimated the association between hyperuricemia (or SUA level) and systemic hypertension and MS. Hyperuricemia association with systemic hypertension was independent of age, body-mass index (BMI), smoking and alcoholism (OR: OR: 4.6050; p = .000256), and MS components (OR: 4.1296; IC95% 1.8330_9.3033; p = .000621). Hyperuricemia increased risk of systemic hypertension by 4,6 -fold. SUA level was associated with MS, independently of other classic component factors of the syndrome (OR:1.34, p = .0129). Hyperuricemia and high SUA levels were associated with MS and systemic hypertension. Effect of hyperuricemia in systemic hypertension is independent of age, BMI, lifestyle, and MS factors. SUA levels are independently associated with MS.
