摘要

BACKGROUND Non-alcoholic fatty liver disease(NAFLD)is a common disorder,with an estimated prevalence ranging from 20%to 35%in the general population.Several scores based on easily measurable biochemical and clinical parameters,including the fatty liver index(FLI),hepatic steatosis index(HSI),lipid accumulation product(LAP),and NAFLD liver fat score(LFS),have been developed for the detection of NAFLD.However,comparative information regarding the efficacy of these scores for predicting NAFLD in population-based samples comprising normal and high-risk individuals is lacking.AIM To evaluate four NAFLD detection scores in two samples with different NAFLD risks.METHODS NAFLD screening was performed in a population-based sample of 50-year-old individuals in Uppsala,Sweden[n=310;Prospective investigation of obesity,energy and metabolism(POEM)study]and a high-risk population comprising patients with a body mass index>25 kg/m2 and either high plasma triglycerides(≥1.7 mmol/L)or type 2 diabetes(n=310;EFFECT studies).NAFLD was defined as liver fat>5.5%using magnetic resonance imaging-proton density fat fraction.FLI,HSI,LAP,and NAFLD LFS were assessed.A logistic regression model was used to evaluate the effectiveness of the different scores.RESULTS The prevalence of NAFLD was 23%in POEM.FLI showed the highest receiver operating characteristic area under the curve(ROC AUC;0.82)and was significantly better than the LAP score(P=0.005 vs LAP,P=0.08 vs LFS,P=0.12 vs HSI)for detection of NAFLD.The other three indices performed equally in POEM(0.77-0.78).The prevalence of NAFLD was 74%in EFFECT;LFS performed best(ROC AUC 0.80)in this sample.The ROC AUC for LFS(0.80)was significantly higher than that for FLI(P=0.0019)and LAP(P=0.0022),but not HSI(P=0.11).We performed a sensitivity analysis with stratification for the two high-risk subgroups(patients with diabetes or hypertriglyceridemia)from the EFFECT studies.LAP performed best in patients with hypertriglyceridemia.No major differences were observed between the other scores.CONCLU
