Abstract
Introduction: NAFLD is strongly associated with metabolic syndrome, and for many years, fatty liver was an exclusive feature of obese patients. The study tries to assess whether the body mass index (BMI) and body circumference is correlated to steatosis, fibrosis, or inflammatory activity of the liver.
Methods: 81 patients with recent hepatic biopsy were included in the study and were weighed and measured. The biopsy results were compared to the measurements.
Results: The average BMI overall for the whole lot was 30.16. There was a significant difference in BMI across the inflammatory activity categories (p = 0.009): groups with higher necro inflammatory activity tended to have higher BMI values (average values per grade: 0–28, 1–29, 2–33, 3–32, 4–29). There was no significant difference for grades of steatosis (p = 0.871). With regards to waist circumference, the overall average was 90.70cm/35.70in. There was a significant difference across the steatosis categories (p < 0.001): groups with higher steatosis scores had higher waist circumferences (average values per grade: 1–77cm / 30 in, 2–95 cm / 37 in, 3–94 cm / 37 in). There was no significant difference for grades of activity (p = 0.058).
Conclusion: BMI and waist circumference are easy to measure, non-invasive parameters, which could be useful in screening patients at higher risk for necro inflammatory activity or severe steatosis.
