ObjectiveTo examine how urate concentrations are related to the risk of having possible REM sleep behavior disorder (pRBD) in a community-based cohort.MethodsThe study included 12,923 Chinese adults of the Kailuan Study, free of Parkinson disease (PD) and dementia. Plasma urate concentrations were measured in 2006, 2008, and 2010. Cumulative average urate concentration was used as primary exposure. In 2012, we determined pRBD status using a validated RBD questionnaire-Hong Kong (RBDQ-HK). Logistic regression analysis was performed to estimate the association between urate concentrations during 2006-2010 and odds of having pRBD in 2012 or pRBD case with symptom onset within 1 year.ResultsHigher average urate concentrations were associated with a lower odds of pRBD (P-trend InterpretationHigher average urate concentrations were associated with a lower likelihood of having pRBD, but not new-onset pRBD. Because of its observational study design, the result should be interpreted with caution due to the possibility of residual confounding.
