What this trial studies

This observational study evaluates two methods for assessing protein intake in patients with chronic kidney disease (CKD) stages 4 and 5. The study compares the traditional 24-hour urine urea measurement with a detailed 3-day dietary record and Food Frequency Questionnaire (FFQ) to determine the most effective approach for introducing a low-protein diet. The goal is to better understand dietary habits and facilitate dietary modifications to delay the need for dialysis. Conducted in the PACA region of France, the study aims to improve dietary management for CKD patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with stage 4 or 5 chronic kidney disease who are motivated to follow a hypo-protein diet.

Not a fit: Patients currently undergoing dialysis or those with ongoing cancer or significant undernutrition may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance dietary management strategies for CKD patients, potentially delaying the need for dialysis.

How similar studies have performed: While the approach of assessing dietary intake is common, this specific comparison of methods in CKD patients is less explored, making it a novel investigation.
