目的:设计一个适合中国人群的、能够快速筛检非酒精性脂肪肝( NAFLD)的简易筛检工具,进而为其有效管理及防治提供科学依据。方法采用横断面病例对照研究设计方法,以2013年1月1日—8月31日在西京医院体检中心接受健康体检的15000名成年人为研究对象。每名研究对象均接受肝脏超声检查、人体学测量、实验室检查及问卷调查4种评估。采用SAS 9.2和SPSS 13.0统计软件进行统计学分析,基于多因素Logistic回归分析的结果,构建NAFLD筛检指数。结果15000名研究对象中有4573人被排除,最终纳入10427人,经超声诊断,其中有2215人被诊断为NAFLD,为病例组;其余8212人为对照组。将10427名研究对象随机分成两组,其中一组为训练样本( n=5213),另一组为验证样本( n =5214)。逐步多因素Logistic 回归分析显示,体质指数( BMI )、三酰甘油(TG)、空腹血糖(FPG)、天冬氨酸氨基转移酶(AST)/丙氨酸氨基转移酶(ALT)对NAFLD的影响有统计学意义(P<0.05)。这些变量被用于构建NAFLD筛检指数: NAFLD指数=2×BMI+TG+FPG-6×(AST/ALT)。该指数在训练样本中的受试者工作特征(ROC)曲线下面积为0.843〔95%CI (0.831,0.855)〕,在验证样本中的ROC曲线下面积为0.848〔95%CI (0.837,0.860)〕。结论 NAFLD指数是一个针对中国人群的简单的、有效的NAFLD筛检工具,其可为进一步的评价和/或详尽的生活方式治疗筛选对象提供依据,并有可能增加筛检的成本效益值。
目的:設計一箇適閤中國人群的、能夠快速篩檢非酒精性脂肪肝( NAFLD)的簡易篩檢工具,進而為其有效管理及防治提供科學依據。方法採用橫斷麵病例對照研究設計方法,以2013年1月1日—8月31日在西京醫院體檢中心接受健康體檢的15000名成年人為研究對象。每名研究對象均接受肝髒超聲檢查、人體學測量、實驗室檢查及問捲調查4種評估。採用SAS 9.2和SPSS 13.0統計軟件進行統計學分析,基于多因素Logistic迴歸分析的結果,構建NAFLD篩檢指數。結果15000名研究對象中有4573人被排除,最終納入10427人,經超聲診斷,其中有2215人被診斷為NAFLD,為病例組;其餘8212人為對照組。將10427名研究對象隨機分成兩組,其中一組為訓練樣本( n=5213),另一組為驗證樣本( n =5214)。逐步多因素Logistic 迴歸分析顯示,體質指數( BMI )、三酰甘油(TG)、空腹血糖(FPG)、天鼕氨痠氨基轉移酶(AST)/丙氨痠氨基轉移酶(ALT)對NAFLD的影響有統計學意義(P<0.05)。這些變量被用于構建NAFLD篩檢指數: NAFLD指數=2×BMI+TG+FPG-6×(AST/ALT)。該指數在訓練樣本中的受試者工作特徵(ROC)麯線下麵積為0.843〔95%CI (0.831,0.855)〕,在驗證樣本中的ROC麯線下麵積為0.848〔95%CI (0.837,0.860)〕。結論 NAFLD指數是一箇針對中國人群的簡單的、有效的NAFLD篩檢工具,其可為進一步的評價和/或詳儘的生活方式治療篩選對象提供依據,併有可能增加篩檢的成本效益值。

Objective To design a simple screening tool that can be used for the fast screening of nonalcoholic fatty liver disease ( NAFLD) among Chinese people , in order to provide scientific references for the effective management , prevention and treatment of NAFLD.Methods In this cross-sectional case control study , we enrolled 15 000 adults who received physical examination in Xijing Hospital from January 1 to August 31, 2013.The subjects received liver ultrasonography , anthropometric measurement , laboratory examination and questionnaire survey.SAS 9.2 and SPSS 13.0 were used to conduct statistic analysis , and NAFLD screening index was constructed based on the results of multivariate logistic regression analysis .Results After the exclusion of 4 573 subjects, we at last enrolled 10 427 subjects.Through ultrasonic diagnosis , 2 215 subjects were diagnosed with NAFLD and were assigned into case group; the rest 8 212 subjects were enrolled as control group.The 10 427 subjects were randomly divided into two samples: training sample ( n=5 213 ) and verification sample ( n=5 214 ) .Stepwise multivariate logistic regression analysis showed that BMI , TG, FPG and AST/ALT had significant influence on NAFLD ( P<0.05) .These variables were used to construct NAFLD screening index: NAFLD index=2 ×BMI+TG+FPG-6 × ( AST/ALT) .The AUC of the index was 0.843 〔95%CI (0.831, 0.855)〕 in the training sample and was 0.848 〔95%CI (0.837, 0.860)〕 in the verification sample.Conclusion NAFLD index is a simple and effective NAFLD screening tool for Chinese people.It can screen patients who need further evaluation and/or specific living style management and may increase the cost -effectiveness of screening.
