Sleep Disorders and Biliary Tact Disease: A Mendelian Randomization

Abstract

Abstract Background: Sleep disorders can cause a wide variety of diseases, however, his relationship with cholelithiasis has not been proven. The importance of this study is further indicated by the fact that the population of insomnia is on the rise every year. Aims: By understanding the causal relationship between sleep disorders and cholelithiasis through a Mendelian randomization method, we can better guide human work and rest to improve the quality of human life. Methods: We use exposure factors from UK Biobank and FinnGen consortia as well as outcome variables using Multivariate Univariate as well as Multivariate Multifactor Mendelian randomization methods to analyze the causal relationship between insomnia and cholelithiasis. Results: The results show that Nap during the day can increase the risk of cholelith (OR = 1.55 (1.10, 2.18), P = 0.011, P FDR = 0.078)and broad cholelith(OR = 1.54 (1.09, 2.17), P = 0.012, P FDR = 0.085). And, after further tests of multi-factor Mendelian randomization, the same results were still obtained (Cholelith P =0.04,Broad Cholelith P=0.04). Conclusions: Nap during the day can increase the risk of gallstone disease. This result was obtained by Mendelian randomization, and the present study was proved to be solid by sensitivity analysis.
