超声诊断非酒精性脂肪肝与体质指数及血清三酰甘油关系的分析

Analysis of Relationship Between the Non-alcoholic Fatty Liver Diagnosed by Ultrasonogram and Body Index and Serum Triglyceride

目的 :探讨非酒精性脂肪肝与体质指数 (BI)和血清三酰甘油 (STG)的关系。方法 :对应用 B型超声检出的 80例脂肪肝患者 (病例组 ) ,与同时进行健康体检的正常人 (对照组 ) 80例进行比较。分别计算 BI,并抽血作 STG测定 ,然后分别计算 BI和 STG升高的 OR值及其 95 %的可信限(CI)并对其进行分层分析。再根据超声图像上脂肪肝的程度与 BI和 STG的异常率的关系进行分析。结果 :病例组 BI和 STG异常率明显大于正常对照组 ,x2 分别为 4 5 .3、4 8,P均 <0 .0 1,BI>2 5的 OR为 12 .5 (95 % CI为 6.0 1～ 2 6.0 )、STG升高的 OR为 2 2 .9(95 % CI为 9.5～ 5 5 .0 )。应用 M- H分层分析 ,BI>2 5和 STG升高是脂肪肝的两个独立危险因素。同时随着 B超声像图上脂肪肝程度的加重 ,BI和 STG异常率亦增加。结论 :BI。

Objective:To investigate the relationship between the non alcoholic fatty liver and body index and serum triglyceride.Method:Eighty patients with fatty liver(case group)and eighty normal persons(control group)were examined by ultrasonic diagnosis and compared between the two groups.Firstly,body index(BI)was calculated and serum triglyceride(STG)was measured,respectively.Secondly,OR(OR95%CI)value of BI>25 and STG≥1.8mmol/L were calculated,and then the stratified analysis were carried to BI and STG.Finally,the relationship between the degree of fatty liver on the ultrosonic image and the abnormal rate of BI and STG were analysed.Result:The abnormal rate of BI and STG in patients with fatty liver was higher than that in the control group,x 2 was 45.3 and 48,respectively(P<0.01),The OR value of BI>25 was 12.5(95%CI:6.01～26.0).The OR value of rised STG was 22.9(95%CI:9.5～55.0).With M H stratified analysis,BI>25 and the rise of STG were the two independent risk factors of fatty liver.The abnormal rate of BI and STG increased with the degree of fatty liver aggravation on the real time ultrasonic image.Conclusion:The rise of BI and STG is associated with fatty liver and its change on ultrasonogram.
