| Summary: | Background Sleep problems are increasingly common in residents with the acceleration of pace of life. Studies have shown that sleep duration is associated with chronic diseases such as hypertension and diabetes, but there is a lack of research on its association with hyperuricemia. Objective To assess the association and its dose-response level between sleep duration and hyperuricemia. Methods Data stemmed from the 2019 surveillance of epidemiology and risk factors of chronic diseases in adult residents in Haidian District, Beijing, involving individuals aged 18-79 years old, with an experience of living in Haidian District at least six months. The information was obtained via a face-to-face questionnaire survey, including the following aspects: demographics (sex, age, education level, marital status, occupation) , lifestyle factors (smoking and drinking, physical activity level, sleep duration) , history of chronic diseases (hypertension and diabetes) , height, weight, blood pressure, laboratory indices (fasting blood glucose, serum uric acid, and serum creatinine) . A multivariable Logistic regression model was used to assess the association between sleep duration and the risk of hyperuricemia, whose dose-response relationship was analysed using restricted cubic spline regression. Results A total of 5 380 people were enrolled, with an average age of (46.9±16.0) years and an average sleep duration of (7.24±1.16) hours. Univariate Logistic regression analysis showed that, compared with those with 7-9 hours of sleep duration, the risk of hyperuricemia increased in those with less than 7 hours of sleep duration and in those with greater than 9 hours of sleep duration 〔OR (95%CI) =1.30 (1.12, 1.51) ; OR (95%CI) =1.48 (1.15, 1.89) 〕. After adjusting for age, gender, education level, marital status, occupation, smoking, drinking, physical activity level, BMI, hypertension, diabetes, and serum creatinine, the risk of hyperuricemia still increased in those with less than 7 hours of sleep duration and in those with greater than 9 hours of sleep duration 〔OR (95%CI) =1.37 (1.17, 1.62) ; OR (95%CI) =1.39 (1.07, 1.81) 〕. Restricted cubic spline regression analysis showed that sleep duration had a U-shaped association with hyperuricemia (non-linear test, χ2=27.530, P<0.001) . Conclusion Too longer or shorter sleep duration was a factor responsible for increased risk of hyperuricemia among adults in Haidian District of Beijing.
