  Purpose

Protein-energy malnutrition and muscle wasting are a common finding among patients with liver cirrhosis. Its prevalence may range from 50-90% depending on the methods used for nutritional assessment. Even stable cirrhotic patients referred as Child A have muscle depletion and the majority of patients classified as Child C have significant depletion.

Despite the importance of nutritional status in patient's outcome, there is no gold standard for nutritional assessment. Traditional techniques used in healthy subjects to assess nutritional status cannot be used in cirrhotic patients due especially to ascites and peripheral edema, and altered rates of biochemical markers due to liver failure.

Bioelectrical impedance vector analysis has emerged as a useful method to assess body composition and nutritional status especially in patients at the extremes of body weight (fluid overload, excess of adipose tissue, etc.).

The purpose of this study is to validate bioelectrical impedance vector analysis as a useful method for nutritional assessment in cirrhotic patients.
