What this Trial Is About
Researchers are studying how calcium and phosphorus balance relates to the stage of chronic kidney disease in adults with stage 4 and 5 disease. This balance is assessed by comparing dietary intake with urinary excretion. The study also compares two methods of tracking diet: image-based dietary assessment and weighted food records. Participants will be asked to take photos of all food and drinks consumed over 24 hours. They are also offered to weigh their food and drinks for 3 days to provide detailed dietary records. These methods will be compared to evaluate their accuracy. During the study, researchers will measure various outcomes including calcium and phosphate balance, urinary and plasma levels of minerals, and dietary intake details over a 3-day period. Participants will be monitored for kidney function and mineral balance. The study begins in December 2025 and continues through May 2029.
