Background:Hypertension and non-alcoholic fatty liver disease(NAFLD)share several pathophysiologic risk factors,and the exact relationship between the two remains *** study aims to provide evidence concerning the relationship between hypertension and NAFLD by analyzing data from the National Health and Nutrition Examination Survey(NHANES)2017-2018 and Mendelian randomization(MR)***:Weighted multivariable-adjusted logistic regression was applied to assess the relationship between hypertension and NAFLD risk by using data from the NHANES ***,a two-sample MR study was performed using the genome-wide association study(GWAS)summary statistics to identify the causal association between hypertension,systolic blood pressure(SBP),diastolic blood pressure(DBP),and *** primary inverse variance weighted(IVW)and other supplementary MR approaches were conducted to verify the causal association between hypertension and *** analyses were adopted to confirm the robustness of the ***:A total of 3144 participants were enrolled for our observational study in *** multivariable-adjusted logistic regression analysis suggested that hypertension was positively related to NAFLD risk(odds ratio[OR]=1.677;95%confidence interval[CI],1.159-2.423).SBP≥130 mmHg and DBP≥80 mmHg were also significantly positively correlated with ***,hypertension was independently connected with liver steatosis(β=7.836[95%CI,2.334-13.338]).The results of MR analysis also supported a causal association between hypertension(OR=7.203[95%CI,2.297-22.587])and *** results were observed for the causal exploration between SBP(OR=1.024[95%CI,1.003-1.046]),DBP(OR=1.047[95%CI,1.005-1.090]),and *** sensitive analysis further confirmed the robustness and reliability of these findings(all P>0.05).Conclusion:Hypertension was associated with an increased risk of NAFLD.

To the Editor: Fatty liver diseases, including nonalcoholic fatty liver disease and alcohol related fatty liver disease, have become a major public health concern [ 1, 2 ]. Fatty liver diseases have been shown to progress through various stages, from steatosis or necrosis with inflammation and hepatocyte damage to the development of fibrosis and eventual cirrhosis with an increased risk of carcinoma [ 2, 3 ].
