Obesity (defined by a body mass index [BMI] of at least 30 kg/m2) is a major public health problem-the upward trend in obesity prevalence across regions and continents is a worldwide concern. Obesity increases the risk for cardiovascular disease and death. In the general population, obesity hastens death by 9.4 years. Obesity is an independent risk factor for CKD. Besides its contribution to the development of diabetes and hypertension, increased fat mass may also have a direct impact on kidney function.
