With the increasing prevalence of obesity, type 2 diabetes, and related metabolic disorders, NAFLD has become an important public health concern in Asia.
The Fatty Liver Index is a simple and accurate predictor of nonalcoholic fatty liver disease (NAFLD) in in the general population. The “fatty Liver index” (FLI)  is accurate and easy to employ as BMI, waist circumference, triglycerides and GGT are routine measurements in clinical practice.
A recent Korean study indicates that Fatty Liver Index , a simple surrogate measure of hepatic steatosis, is a useful and easily accessible tool for identifying individuals at high risk for DM.
Generally, a Fatty Liver Index < 30 ruled out and a Fatty Liver Index ≥ 60 ruled in hepatic steatosis as detected by ultrasonography. A chinese study in 2015 validated the accuracy of the Fatty Liver Index for predicting NAFLD in a large general Chinese population, and determined that the optimal cut-off point of the Fatty Liver Index for NAFLD was 30 in middle-aged and elderly Chinese.
The formula that calculates the probability of fatty liver disease occurrence is:
FLI = (e 0.953*loge (triglycerides) + 0.139*BMI + 0.718*loge (ggt) + 0.053*waist circumference – 15.745) / (1 + e0.953*loge (triglycerides) + 0.139*BMI + 0.718*loge (ggt) + 0.053*waist circumference – 15.745) x 100
