Brief summary

Unlike the general population, a higher body mass index (BMI) is associated with greater survival among patients with chronic kidney disease (CKD). However, obesity is defined as excess body fat that associated with clearly elevated health risks according to the World Health Organization. In addition, muscle wasting is prevalent among CKD subjects. Thus, we hypothesized that different definition of obesity, based on BMI or body fat percentage, might have different impact on clinical outcomes among CKD population.
