Chapter 19 - <strong>Nutrition</strong> <strong>Interventions</strong> <strong>for</strong> Chronic Renal Failure<br />

Normal growth and development depends on many factors, the main one being<br />

adequate nutrition support. <strong>Nutrition</strong> management of children <strong>with</strong> CKD involves<br />

meeting nutrient needs while avoiding excesses of substances that accumulate<br />

because of renal insufficiency. A child <strong>with</strong> CKD needs to receive adequate energy<br />

<strong>for</strong> weight gain and at least the DRI <strong>for</strong> protein. Protein restriction below the Dietary<br />

Reference Intake (DRI) has not been found to be beneficial <strong>for</strong> children <strong>with</strong> CKD<br />

(7). Sodium may be restricted if hypertension is a problem. Sodium, potassium, and<br />

phosphorus are restricted if blood levels are high and increased if levels are low.<br />

There is not one specific diet that meets the needs of all children <strong>with</strong> CKD.<br />

CKD is staged by a combination of age, height, and creatinine level. The glomerular<br />

filtration rate (GFR) is estimated by the Schwartz <strong>for</strong>mula <strong>for</strong> children 2 years of age<br />

and older. Confirm CKD stage <strong>with</strong> nephrologist(8).<br />

GFR (ml/min/1.73m²) = (0.413 x height (cm)/creatinine (mg/dL))<br />
