We assessed the validity of a recently developed dish composition database (DCD) against urinary biomarkers compared with a standard food composition database (FCD).
Intakes of protein, Na and K were estimated by 2 × 24 h urine collections and by 4 d dietary record data based on the DCD (including 128 dishes) or FCD (including 1878 foods).
Japan.
A total of 161 men and 163 women aged 20-69 years.
Compared with the 24 h urine-based estimates, the median intakes estimated using the DCD and FCD differed significantly for protein and Na in men and for Na and K in women. Deattenuated Spearman correlation coefficients using 24 h urine-based estimates for the intakes of protein, Na and K were lower in the DCD (respectively: 0·26, 0·15 and 0·44 in men; 0·22, 0·27 and 0·22 in women) than those in the FCD (respectively: 0·43, 0·40 and 0·59 in men; 0·33, 0·45 and 0·42 in women). When data on dish portion size reported by participants were used for estimation instead of standard portion-size data based on the DCD, the accuracy of the estimated median intakes did not change notably, whereas the deattenuated correlation coefficients improved (for protein, Na and K respectively: 0·32, 0·31 and 0·56 in men; 0·31, 0·41 and 0·39 in women).
The DCD supported by individual-level information on dish portion size showed fair to moderate validity in ranking individuals according to their intakes of protein, Na and K, similar to the FCD.
我们评估了一个最近开发的餐盘成分数据库(DCD)与标准食物成分数据库(FCD)相比,其用于评估尿液生物标志物的有效性。
通过 2×24 小时尿液收集和基于 DCD(包括 128 道菜)或 FCD(包括 1878 种食物)的 4 天饮食记录数据,估计蛋白质、Na 和 K 的摄入量。
日本。
共有 161 名男性和 163 名年龄在 20-69 岁的女性。
与 24 小时尿液估计值相比,DCD 和 FCD 估计的蛋白质和 Na 摄入量在男性中存在显著差异,而在女性中则是 Na 和 K 的摄入量存在显著差异。使用 24 小时尿液估计值对蛋白质、Na 和 K 摄入量进行去关联 Spearman 相关系数,DCD 中的相关系数(男性分别为 0.26、0.15 和 0.44;女性分别为 0.22、0.27 和 0.22)低于 FCD(男性分别为 0.43、0.40 和 0.59;女性分别为 0.33、0.45 和 0.42)。当使用参与者报告的餐盘份量数据进行估计,而不是基于 DCD 的标准份量数据时,估计中位数摄入量的准确性没有显著变化,而去关联相关系数有所改善(对于蛋白质、Na 和 K,男性分别为 0.32、0.31 和 0.56;女性分别为 0.31、0.41 和 0.39)。
支持个体餐盘份量信息的 DCD 在根据个体蛋白质、Na 和 K 的摄入量对个体进行排序方面表现出良好到中度的有效性,与 FCD 相似。
