Abstract

Purpose: Sarcopenia, associated with morbidity and mortality, is a common geriatric syndrome in older adults. In this study, we investigated the relationship between uric acid, which is a powerful antioxidant and has intracellular proinflammatory activity, and sarcopenia in older adults.

Methods: This is a cross-sectional retrospective study involving a total of 936 patients. The diagnosis of sarcopenia was evaluated based on the EGWSOP 2 criteria. The patients were divided into two groups according to hyperuricemia (for females > 6 mg/dl, for males > 7 mg/dl); hyperuricemia and control.

Results: The frequency of hyperuricemia was 65.40%. Patients with hyperuricemia were older than the control group and female gender frequency was higher (p = 0.001, p < 0.001, respectively). Sarcopenia was negatively associated with hyperuricemia as a result of the adjustment analysis made according to demographic characteristics, comorbidities, laboratory results, malnutrition, and malnutrition risk. (p = 0.034). Besides, muscle mass and muscle strength were associated with hyperuricemia (p = 0.026 and p = 0.009, respectively).

Conclusions: Considering the positive effect of hyperuricemia on sarcopenia, avoiding aggressive uric acid-lowering therapy may be a good option in older adults with asymptomatic hyperuricemia.
