Association between Serum Uric Acid Levels and Sleep Variables : Results from the National Health and Nutrition Survey 2005–2008

الملخص EN

Sleep disordered breathing as well as high serum uric acid levels are independent risk factors for cardiovascular disease.

However, studies evaluating the relationship between sleep-disordered breathing and hyperuricemia are limited.

We examined the 2005–2008 National Health and Nutrition Examination survey's sleep variables and high serum uric acid among 6491 participants aged ≥20 years.

The sleep variables included sleep duration, snoring, snorting, and daytime sleepiness.

The main outcome was high serum uric acid level, defined as levels of serum uric acid >6.8 mg/dL in males and >6.0 mg/dL in females.

We found that snoring more than 5 nights per week, daytime sleepiness, and an additive composite score of sleep variables were associated with high serum uric acid in the age- , sex-adjusted model and in a multivariable model adjusting for demographic and lifestyle/behavioral risk factors.

The association was attenuated with the addition of variables related to clinical outcomes such as depression, diabetes, hypertension, and high-cholesterol levels.

Our results indicate a positive relationship between sleep variables, including the presence of snoring, snorting, and daytime sleepiness, and high serum uric acid levels.
