We assessed the relationship between protein intake (calculated from a 3-day prospective dietary diary) and 24-h urinary urea excretion in 37 children with chronic renal failure. Protein intake was not restricted during the investigation period. The 24-h urinary urea excretion correlated poorly with the protein intake estimated from the dietary diary (r = 0.58). We conclude that although it is common practice to assess compliance with a protein-restricted diet in children with chronic renal failure with a dietary diary and 24-h urinary urea excretion, the value of this assessment is questionable.
我们评估了37名慢性肾衰竭儿童的蛋白质摄入量（根据3天前瞻性饮食日记计算）与24小时尿尿素排泄之间的关系。在调查期间，蛋白质摄入量未受限制。24小时尿尿素排泄与饮食日记估计的蛋白质摄入量相关性较差（r = 0.58）。我们得出结论，虽然在慢性肾衰竭儿童中用饮食日记和24小时尿尿素排泄来评估蛋白质限制饮食的依从性是常见做法，但这种评估的价值值得怀疑。
