Changes of percent body fat as a useful surrogate for risk of declined renal function
The association between anthropometric indices with chronic kidney disease (CKD) was examined previously. 
However, the effect of body fat on renal function was not determined clearly. Our aim was to investigate the association of percent body fat (PBF) and renal function in adult population from health examination in Tri-Service General Hospital (2010–2016). 35087 participants aged 20 years and older were enrolled in the study. PBF was measured by bioelectrical impedance analysis (BIA).
