|概要||ResultsThe parameters for the candidate multivariate regression models were male gender, age, body mass index (BMI), diabetes mellitus, dyslipidemia, proteinuria, estimated glomerular filtration rate, serum albumin level, spot urinary UN and creatinine level, and spot urinary UN/creatinine levels. The final model contained BMI and spot urinary Un level. The final model was selected because of the higher correlation between the predicted and measured protein intakes r=0.558(95%CI 0.400, 0.683), and the smaller distribution of the difference between the measured and predicted protein intakes than those of the other models.
conclusionThe results suggest that Un concentration in spot urine may be used to estimate daily protein intake and that a prediction formula would be useful for nutritional control in CKD patients.
