Official title
The CPH-MBD Cohort - Substudy on Dietary History
Overview
The aim of the study is to assess the association between the calcium and phosphorus balance and the stage of kidney disease measured by creatinine clearence in patients with chronic kidney disease stage 4 and 5. The balance is measured a measurement between the recorded diatery intake and the urinary excretion. Additionally a comparison between image based diatery accessment and weighted records will be measured
Detailed description
All participants will be asked to take photos of all the food and fluids they consume during 24 hours. Additionally participants will be offered to weight their food and fluid for 3 days.
Primary outcome measures
- Comparison of diatery photograph method with weighted records. [Time frame: 3 days]
- Calcium and phosphate balance in relation to the stage of kidney disease [Time frame: 3 days]
Secondary outcome measures (12)
- Urinary Calcium [Time frame: 3 days]
- Urinary phosphate [Time frame: 3 days]
- Calcium intake total and the distribution of vegetarian and animal sources [Time frame: 3 days]
- Phosphate intake total and the distribution of vegetarian and animal sources [Time frame: 3 days]
- sodium intake total and the distribution of vegetarian and animal sources [Time frame: 3 days]
- Energy intake [Time frame: 3 days]
- Protein intake [Time frame: 3 days]
- Fat intake [Time frame: 3 days]
- Fluid intake [Time frame: 3 days]
- Plasma phosphate [Time frame: 3 days]
- Plasma calcium [Time frame: 3 days]
- Urinary creatinine [Time frame: 3 days]
