Cross-sectional study of multiple metabolic disorders in patients with essential hypertension and nonalcoholic fatty liver disease / 中华检验医学杂志

ABSTRACT

Objective To investigate the incidence of non-alcoholic fatty liver disease (NAFLD) in essential hypertension patients and the relation between NAFLD and multiple metabolic disorders.Methods Cross-sectional study.Between January 2006 and July 2008,1109 inpatients in Beijing Anzhen hospital diagnosed with essential hypertension were enrolled into this study (542 femal,567 male,mean age 61 ± 11).All patients had ultrasound screening for fatty liver.The prevalence of NAFLD,serum alanine aminotransferase abnormality ratio,the relationship between NAFLD and multiple metabolic abnormalitiesincluding glucose,dyslipidemia,hyperuricemia.471 cases of non-EH as a control group in the same period of admission(216 femal,255 male,mean age 62 ± 10).The measurement data of two groups were compared with t test,while the count data were compared with x2 test.Multiple Logistic regression was used to analysis therisk factors of EH with NAFLD.Results Among 1109 recruited patients,37.3％ (414/1109) had fatty liver by ultrasonography.EH patients were divided into NAFLD group and non-NAFLD group.In EH coexisted with NAFLD group,the prevalence of diabetes mellitus (21.0％ ∶ 10.8％),metabolic syndrome (59.4％ ∶ 44.7％),overweight (71.3％ ∶ 62.9％) and the levels of BMI (26.90 ± 3.66∶ 26.35 ± 3.56),TC (5.30±1.17∶ 5.12 ± 1.09),TG(2.11 ± 1.43∶1.85 ± 1.33),ALT(45.18 ± 37.62∶39.22 ±32.27) were significantly higher than those in the non-NAFLD group (P ＜0.05).HDL-C (1.53 ±0.53∶1.62 ±0.54)was significantly lower than that in the non-NAFLD group (P ＜ 0.05).In non-NAFLD group,prevalence of overweight and the levels of BMI,TC,TG,ALT were signific antly higher than those in non-EH group (P ＜ 0.01).By multivariable logistic regression analysis,diabetes mellitus,hypercholesteremia,hyperuricemia and BMI were risk factors in NAFLD patients with essential hypertension.Conclusion NAFLD was more prevalent in patients with EH complicated with multiple metabolic disorders,such as hyperlipemia and hyperuricemia.
