Key result
Short sleep duration is linked to ~7% higher incident hyperuricemia risk vs normal sleep.
Why the study?
Little is known about the association of sleep duration with hyperuricemia, especially from longitudinal studies.
Does sleep duration affect the risk of incident hyperuricemia in Chinese adults?

Does sleep duration affect the risk of incident hyperuricemia in Chinese adults?
Sleep duration is inversely associated with incident hyperuricemia, suggesting that sufficient sleep may play a role in its prevention.
Short sleep was associated with higher hyperuricemia risk and long sleep with lower risk; leaves open whether sleep modification prevents hyperuricemia.
Little is known about the association of sleep duration with hyperuricemia. Especially lacking is evidence from longitudinal studies. Based on the MJ Health Examination Database in Beijing, China, a prospective study was designed. Participants were classed into short, normal, and long groups by sleep duration. The Cox regression model was used to estimate the hazard risk of hyperuricemia for short or long sleep duration compared with the normal group after adjusting for potential confounders. During a median 3.08 years follow-up, 4868 (14.31%) incident hyperuricemia events were documented among 34,025 participants with a crude incidence rate of 39.49 per 1000 persons. Years after adjusting for potential confounders, a 7% higher risk of hyperuricemia in the short sleep duration group (<7 h, 95% confidence interval: 1.01−1.14) and a 15% lower risk in the long sleep duration group (≥8 h, 95%CI: 0.74−0.97) were found compared with the normal group (7−8 h) (p for trend < 0.001). Nevertheless, the association of the short sleep duration group was marginally significant after further adjustment of the count of white blood cells (hazard ratio: 1.07, 95%CI: 1.00−1.13). Sleep duration was inversely associated with hyperuricemia, which highlights the public health significance of sufficient sleep duration for preventing hyperuricemia.

Yu et al. (2022) conducted a cohort in Hyperuricemia (n=34,025). Short sleep duration (<7 hours) vs. Normal sleep duration (7-8 hours) was evaluated on Incident hyperuricemia (HR 1.07, 95% CI 1.01-1.14, p=<0.001). Short sleep duration (<7 hours) was associated with a 7% higher risk of incident hyperuricemia (HR 1.07) compared to normal sleep duration (7-8 hours) in Chinese adults.
