Impact of high body mass index on hepatocellular carcinoma risk in chronic liver disease: A population-based prospective cohort study.

ABSTRACT:

Background and aims

We investigated associations between body mass index (BMI) and hepatocellular carcinoma (HCC) in patients with hepatitis B (HBV) C (HCV) virus infection, alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), and liver cirrhosis (LC).

Methods

We followed 350,608 Korean patients with liver disease who underwent routine health examinations from 2003-2006 until December 2018 via national hospital discharge records. Multivariable adjusted hazard ratios (HRs) per 5-kg/m2 BMI increase (BMI ≥25 kg/m2) for HCC risk were calculated using Cox models. HCC developed in 17,752 patients.

Results

The HRs (95% CI) were 1.17 (1.06-1.28), 1.08 (0.87-1.34), 1.34 (1.14-1.58), 1.51 (1.17-1.94), and 1.11 (1.00-1.23) for HBV, HCV, ALD, NAFLD, and LC, r
