Loss of sleep or disturbance of sleep-wake cycles have been related with metabolic impairments. However, few studies have investigated the association between daily sleep duration and hyperuricemia.We investigated daily sleep duration (daytime napping and nocturnal sleep) with hyperuricemia risk.We cross-sectionally analyzed data from the China Multi-Ethnic Cohort (CMEC), Yunnan region. A total of 22,038 subjects aged 30-79 years were recruited in 2018. Hyperuricemia was defined as serum uric acid (SUA) above 7.0 mg/dL in males and above 6.0 mg/dL in females.Associations between daily sleep duration and hyperuricemia.We found that the longest daytime napping duration was associated with higher risk of hyperuricemia in the crude model [OR (95%CI) is 2.22 (1.88, 2.61), P < 0.0001] and in a multivariable adjustment model [OR: 1.69; 95%CI: (1.41, 2.01), P < 0.0001] after adjusting for demographic, sleep habits and metabolic risk factors. The association was moderately attenuated with additionally adjusted for serum creatinine [OR: 1.54; 95%CI: (1.28, 1.86), P < 0.0001]. Longer daytime napping duration was also related with higher risk of hyperuricemia combined with metabolic syndrome (MetS). Respondents in the daytime napping duration ≥ 90 min presented higher risk of hyperuricemia combined with MetS [OR: 1.39; 95%CI: (1.06, 1.79); P < 0.001] in fully adjusted model. We did not observe any relation between nocturnal sleep duration and risk of hyperuricemia in the study.Longer daytime napping duration (but not nocturnal sleep duration) was independently associated with risk of hyperuricemia in Chinese population.
