Introduction:

non-alcoholic fatty liver disease is a clinical and morphological condition characterized by fatty infiltration of the liver in more than 5%; it has two stages: simple steatosis and steatohepatitis, which can progress to fibrosis, cirrhosis and hepatocellular carcinoma.

Objective:

to determine the relationship between clinical and epidemiological variables with this disease, as well as fibrosis indices and their relationship.

Methods:

a cross-sectional descriptive study was carried out in patients seen in the liver and biliary tract consultation at " Dr. Celestino Hernández Robau" University Hospital from January to December 2017. We worked with a population made up of 60 overweight or obese patients older than or equal to 20 years who were diagnosed with primary non-alcoholic fatty liver disease.

Results:

the age group between 50-59 years of age, female gender, obese ones and with grade I steatosis prevailed. We found that 73.33% of the patients had metabolic syndrome and grade II steatosis prevailed in them. A number of 28 patients were found with indeterminate and high risk in the FIB-4 and NAFLD classifications, respectively, when relating the risks of fibrosis, as well as 5 had high risk in both variables. The FIB-4 and NAFLD indices had a significant, directly proportional, and considerable correlation.

Conclusions:

the correlation detected between the FIB-4 and NAFLD indices reaffirmed the value in the detection of suspected fibrosis and guided, in clinical practice, the conduct of different patients with this condition.
