Association between triglyceride glucose index and sleep disorders: results from the NHANES 2005-2008

BackgroundTo determine the association between sleep disorders and Triglyceride glucose index.MethodsA cross-sectional analysis of the 2005 to 2008 National Health and Nutrition Examination Survey (NHANES) was performed. The 2005 to 2008 NHANES national household survey for adults >= 20 years was examined for the sleep disorders.TyG index: ln [triglyceride (mg/ dL) x fasting blood glucose (mg/dL)/2].Multivariable logistic and linear regression models were used to explore the association between the TyG index and sleep disorders.ResultsA total of 4,029 patients were included. Higher TyG index is significantly associated with elevated sleep disorders in U.S. adults. TyG was moderately correlated with HOMA-IR (Spearman r = 0.51). TyG was associated with higher odds of sleep disorders(adjusted OR [aOR],1.896; 95% CI, 1.260 2.854), Sleep apnea (aOR, 1.559; 95% CI, 0.660 3.683), Insomnia(aOR, 1.914;95% CI, 0.531 6.896), and Restless legs (aOR, 7.759; 95% CI,1.446 41.634).ConclusionsIn this study, our result shown that population with higher TyG index are significantly more likely to have sleep disorders in U.S. adults.
