The European micronutrient recommendations aligned (EURRECA) Network of Excellence seeks to establish clear guidelines for assessing the validity of reported micronutrient intakes among vulnerable population groups. A systematic literature review identified studies validating the methodology used in elderly people for measuring usual dietary micronutrient intake. The quality of each validation study selected was assessed using a EURRECA-developed scoring system. The validation studies were categorised according to whether the reference method applied reflected short-term intake ( < 7 d), long-term intake ( > or = 7 d) or used biomarkers (BM). A correlation coefficient for each micronutrient was calculated from the mean of the correlation coefficients from each study weighted by the quality of the study. Thirty-three papers were selected, which included the validation of twenty-five different FFQ, six diet histories (DH), one 24-h recall (24HR) and a videotaped dietary assessment method. A total of five publications analysed BM, which were used to validate four FFQ, and one 24HR, presenting very good correlations only for vitamin E. The analysis of weighted correlation coefficients classified by FFQ or DH showed that most of the micronutrients had higher correlations when the DH was used as the dietary method. Comparing only FFQ results showed very good correlations for measuring short-term intakes of riboflavin and thiamin and long-term intakes of P and Mg. When frequency methods are used for assessing micronutrient intake, the inclusion of dietary supplements improves their reliability for most micronutrients.
欧洲微量营养素建议联盟（EURRECA）卓越网络旨在为评估弱势群体报告的微量营养素摄入量的有效性建立明确的指南。一项系统的文献综述确定了验证老年人常用饮食微量营养素摄入量测量方法的研究。使用 EURRECA 开发的评分系统评估了所选验证研究的质量。根据应用的参考方法反映短期摄入量（<7 天）、长期摄入量（≥7 天）或使用生物标志物（BM），将验证研究进行分类。从每个研究的相关系数的平均值计算每个微量营养素的相关系数，权重为研究的质量。选择了 33 篇论文，其中包括 25 种不同的 FFQ、6 种饮食史（DH）、1 种 24 小时回忆（24HR）和一种录像饮食评估方法的验证。共有 5 篇出版物分析了 BM，用于验证 4 种 FFQ 和 1 种 24HR，仅对维生素 E 显示出非常好的相关性。根据 FFQ 或 DH 进行的加权相关系数分析表明，当 DH 用作饮食方法时，大多数微量营养素的相关性更高。仅比较 FFQ 结果表明，短期摄入核黄素和硫胺素以及长期摄入 P 和 Mg 的相关性非常好。当使用频率方法评估微量营养素摄入量时，包含膳食补充剂可提高大多数微量营养素的可靠性。
