Key result
Each extra hour of nightly sleep is linked to lower serum uric acid levels.
Why the study?
Does longer sleep duration improve serum uric acid concentrations and SUA to creatinine ratio in elderly patients with overweight/obesity and metabolic syndrome?

Does longer sleep duration improve serum uric acid concentrations and SUA to creatinine ratio in elderly patients with overweight/obesity and metabolic syndrome?
Longer sleep duration is associated with lower serum uric acid concentrations and SUA to creatinine ratio in elderly patients with metabolic syndrome and high cardiovascular risk.
Longer sleep linked to lower uric acid in high-risk elderly; hypothesis-generating, prospective trials needed before practice change.
The aim of the study was to evaluate sleep duration and sleep variability in relation to serum uric acid (SUA) concentrations and SUA to creatinine ratio. This is a cross-sectional analysis of baseline data from 1842 elderly participants with overweight/obesity and metabolic syndromein the (Prevención con Dieta Mediterránea) PREDIMED-Plus trial. Accelerometry-derived sleep duration and sleep variability were measured. Linear regression models were fitted to examine the aforementioned associations. A 1 hour/night increment in sleep duration was inversely associated with SUA concentrations (β = 0.07, p = 0.047). Further adjustment for leukocytes attenuated this association (p = 0.050). Each 1-hour increment in sleep duration was inversely associated with SUA to creatinine ratio (β = 0.15, p = 0.001). The findings of this study suggest that longer sleep duration is associated with lower SUA concentrations and lower SUA to creatinine ratio.

Papandreou et al. (2019) conducted a cross-sectional in Overweight/obesity and metabolic syndrome (n=1,842). Sleep duration vs. Shorter sleep duration was evaluated on Serum uric acid (SUA) concentrations (β = 0.07, p=0.047). A 1-hour/night increment in sleep duration was inversely associated with serum uric acid concentrations (β = 0.07, p = 0.047) and uric acid to creatinine ratio (β = 0.15, p = 0.001).
