Introduction Chronic kidney disease (CKD) has become a global public health problem and is a common condition in the United States (Alejandro et al.,2009 ; Essam et al.,2008 ; Adam et al., 2007) In 2004, there were approximately 472,000 patients with treated ESRD (Alejandro et al.,2009 ) By 2030, expected to increase to more than 2 million. The estimated prevalence of earlier CKD stages (stages 1 through 4) in US adults was 24 to 28 million based on the 2000 (Adam et al., 2007) 03/05/58 3

Chronic kidney disease: classification and clinical consequences Relative risk of death in relation to kidney function (N=1,120,295 pts) CKD -KDOQI classification Go AS et., /05/58 4

Modification of Diet in Renal Disease (MDRD) in Thailand In 2007 : Chronic Renal Insufficiency patients 13.2% in state 3 and 0.61% in state 4 (Thawee Siriwong, 2007) In 2008 : Chronic Renal Insufficiency patients in Thailand 17.5% ( สมาคม โรคไตแห่ง ประเทศไทย, 2008) 03/05/58 5

Clinical complications of renal failure Parathyroid gland disturbances –renal bone disease Active vitamin D deficiency Atherosclerosis and arteriosclerosis Polyneuropathy No diuresis –overhydration..and many others Malnutrition/wasting Immunodeficiency Myocardial fibrosis and cardiomyopathy Loss of erythropoietin – anaemia 03/05/58 6

Gab of knowledge 03/05/58 7 The relationship of obesity to Renal insufficiency is somewhat controversial. While it is established that obesity increases the risk of hypertension, diabetes and dyslipidemia, it is not clear if excess abdominal waist circumference influences Renal insufficiency independently Correlation between waist circumference and (A) visceral and (B) subcutaneous fat areas assessed by using computed tomography in 75 men (open circle; dotted lines) and 47 women (filled triangle; solid lines) with prevalent chronic kidney disease. Fabiana et al.,2008

Methods A analytic study was conducted all information were collected from medical records of all patients diagnosed with Hypertension during The type of hypertension complications was based on Renal insufficiency was the main outcome of this study. 03/05/58 8 Objective To investigate the association between abdominal waist circumference and Renal insufficiency among hypertensive patients
