NATIONAL NUTRITION SURVEY
Resulted from the mandate of the Food and Research Institute (FNRI) of the Dept. of Science and Technology (DOST)
Objective: To assess the Philippine food situation and nutritional status of the population
Conducted every 5 years since 1978
![Page 4: Chronic Kidney Disease: The Philippine Situation](https://reader034.vdocuments.mx/reader034/viewer/2022050805/5584288dd8b42a86478b4d12/html5/thumbnails/4.jpg)
NNHeS 2003-2004
Objectives
To assess the prevalence of lifestyle and
nutrition-related risk factors and diseases
among Filipinos 2 years and above
To aid in the development of health policies
an programs for the prevention and control
of lifestyle and nutrition-related diseases

NNHeS 2003-2004 Renal Report Chronic Kidney Disease Stages
Stage GFR
1 >=90 Normal or increased GFR
2 60-89 Mildly decreased GFR
3 30-59 Moderately decreased GFR
4 15-29 Severely decreased GFR
5 <15 Kidney failure

NNHeS 2003-2004 Renal Report Renal function
• Abbreviated MDRD formula
– Predicted GFR = 186.3 * (serum creatinine)−
1.154 * age− 0.203 * (0.742 for women) * (1.21 if African American)
• Cockcroft & Gault formula
– Ccr (mL/min) = (140 − age)/sCr * weight/72 * 1.73/BSA, where age is in years, sCr is in mg/dL, weight is in kilograms, and BSA is body surface area using the formula:
– BSA = 0.20247 × [height (m)]0.725 × [weight (kg)]0.425

NNHeS 2003-2004 Renal Report Prevalence of CKD in adults
The population of Filipinos aged 20 The population of Filipinos aged 20 years and above in 2005 was years and above in 2005 was
46,627,17246,627,172
A prevalence of 2.6% means that1,212,306 adult Filipinos
have CKD.

NNHeS 2003-2004 Renal Report Macroalbuminuria
at least +1 proteinuria using the
Multiple Reagent Strip for Urinalysis®
(Bayer Corporation)
The prevalence of macroalbuminuria was
4.2%
