Study Highlights Waist-to-Height Ratio as Key Indicator of Renal Sinus Fat and Kidney Health
A recent study has identified the waist-to-height ratio (WHtR) as a significant non-invasive marker for assessing renal sinus fat (RSF) and its impact on kidney function. The research evaluated various adiposity indices, including body mass index (BMI), waist circumference, and body roundness index (BRI), in relation to RSF. The findings revealed that WHtR, which adjusts abdominal size relative to body height, is more closely linked to RSF accumulation than BMI or total adiposity. This study suggests that WHtR could serve as a practical surrogate for estimating ectopic renal fat burden, particularly in individuals at risk for chronic kidney disease (CKD) due to obesity. The research also found that RSF percentage, rather than absolute RSF volume, was inversely associated with estimated glomerular filtration rate (eGFR), indicating its potential as a sensitive marker of kidney stress.
