Although obesity is known to increase a person’s risk of developing chronic kidney disease (CKD), it has no effect on CKD progression, a study found.

British researchers led by Rebecca N.K.L. Brown, MD, of the University of Manchester in Manchester, U.K., analyzed data from the Chronic Renal Insufficiency Standards Implementation Study, a prospective observational study in a predominantly white population in Greater Manchester. They assessed the rate of CKD progression in 499 adult CKD patients. Neither body mass index as a continuous variable nor obesity (BMI of 30 kg/m2 or higher) was associated with an increased rate of CKD progression, measured as the change in estimated glomerular filtration rate over time.
