Abstract

Defining a patient's body weight in order to calculate their protein and energy prescription is an important step for physicians and dietitians working in the field of kidney diseases. Ideal body weight embraces 2 concepts. It is defined both as “the goal weight at which nutritional requirements are met” and “the body weight associated with the lowest mortality for a given height, age, gender, and frame size”. Both definitions are not generalizable to people living with chronic kidney disease (CKD), and there is no agreed method for how to define ideal body weight in CKD. The epidemiology of CKD patients is continuously changing; recent years have seen a sharp increase in patients' average age and the prevalence of obesity. This paper critically examines the different ways to calculate a “reference” body weight that can be used to estimate and prescribe a patient's intake of energy and nutrients (proteins in particular) and offers some practical suggestions on how this should be done, particularly those who are overweight or obese.

慢性肾病患者理想体重标准计算的安魂曲？

确定病人的体重，以便计算他们的蛋白质和能量处方，是肾脏疾病领域的医生和营养师工作的重要一步。理想体重包含两个概念。它被定义为“满足营养需求的目标体重”和“在给定的身高、年龄、性别和体型下，与最低死亡率相关的体重”。这两种定义都不能推广到慢性肾脏疾病（CKD）患者，对于如何定义CKD患者的理想体重也没有统一的方法。CKD患者的流行病学是不断变化的；近年来，患者的平均年龄和肥胖患病率急剧上升。本文批判性地研究了计算“参考”体重的不同方法，该方法可用于估计和规定患者的能量和营养（特别是蛋白质）摄入量，并就如何做到这一点提供了一些实用的建议，特别是那些超重或肥胖的人。
