Non-adherence with dietary prescriptions in chronic kidney disease

Abstract

Chronic kidney disease (CKD) is a common disorder affecting more than 50 million people worldwide, with approximately 430 000 people reported as suffering from end-stage renal disease in South Africa in 2003. Of equal concern is the reported increase in the prevalence of CKD from 14.5% (1988–1994 NHANES data) to 16.8% (1999–2004 NHANES data) in the United States in people 20 years of age and older. This increase is also likely to be true for other countries and might be related to the increase in the prevalence of obesity, which has recently been identified as an independent and major risk factor for CKD. The effect of obesity is thought to be related to its link with diabetes and hypertension, both known risk factors for CKD.
