Background/Rationale
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)

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% (สมาคมโรคไตแห่�งประเทศไทย, 2008)

Gab of knowledge
200423/ /7
The relationship of obesity to Renal insufficiency is somewhat controversial.
While it is established that obesity increases the risk of hypertension, diabetes and
dyslipidemiait is not clear if excess waist
circumference influences Renal insufficiency
independentlyCorrelation 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.

Demographic characteristics were described using frequency and percentage for categorical data such as gender, age group,WC group, BMI group, Cigarette smoking use, fasting plasma glucose group, total cholesterol group, triglyceride group, HDL cholesterol group, LDL cholesterol group, hemoglobin group and hematocrit group.
Using mean, standard deviation, median, minimum, and maximum to described continuous data such as age, BMI, fasting plasma glucose level, total cholesterol level, triglyceride level, HDL cholesterol level, LDL cholesterol level, hemoglobin level and hematocrit level.
To investigate factors that associated with chronic renal insufficiency, adjusted odds ratios (ORs) and their 95% confidence intervals (95%CIs) were estimated using multiple logistic regression.
All test statistics were p-value of less than 0.05 was considered statistical significant.
All analyses were performed by using STATA version 12.0 (AtataCorp, College Station, TX).

Discussion & Conclusions
In summary, in agreement with the findings in the general population, the present study shows that WC is not associated with Chronic Renal Insufficiency in
individuals. In previous study, associations found between WC and some CVD risk factors were similar to those observed for visceral fat, suggesting that WC is a simple and economic tool to be used more often in epidemiological research also involving patients
with CKD. Prospective studies are necessary to evaluate the reproducibility of WC and the ability of
this method to predict outcomes in patients with CKD.
