There is a high prevalence of malnutrition among people with decompensated liver disease. Standard nutritional screening tools use weight and body mass index (BMI) to identify risk, although these are difficult to measure for those with ascites, often secondary to liver cirrhosis. Dietetic guidance suggests adjusting for ascitic weight by 2.2–14 kg, although there is a lack of evidence to substantiate these values. The present study aimed to measure the contribution of ascitic fluid weight and compare this with the current guidance, as well as to examine whether girth circumference can be used to estimate ascitic weight.

肝硬化患者腹水对体重的贡献及其围长的估算：一项横断面观察研究。

代偿失调的肝病患者中营养不良的患病率很高。标准的营养筛查工具使用体重和体重指数（BMI）来识别风险，尽管对于腹水患者（通常继发于肝硬化）很难测量这些风险。饮食指南建议将腹水重量调整2.2-14公斤，尽管缺乏证据证明这些数值。本研究旨在测量腹水量的贡献并将其与当前指南进行比较，并检查围围是否可用于估算腹水量。
