Evaluating food intake quality may contribute to the development of nutrition programs. In Mexico, there are no screening tools that can be administered quickly for the evaluation of this variable. The aim was to determine the reproducibility of a mini-survey designed to evaluate the quality of food intake (Mini-ECCA) in a Mexican population. Mini-ECCA consists of 12 questions that are based on Mexican and international recommendations for food and non-alcoholic beverage intake, with the support of photographs for food quantity estimation. Each question scores as 0 (unhealthy) or 1 (healthy), and the final score undergoes a classification procedure. Through the framework of a nutritional study, 152 employees of the municipal water company in Guadalajara, Mexico (April⁻August 2016), were invited to participate. The survey was administered in two rounds (test and retest) with a 15-day interval between them. We calculated the Spearman correlation coefficient, the intra-class correlation coefficient (ICC), and weighted kappa for score classification agreement (SPSS versus 14 < 0.05 was considered statistically significant). The survey obtained a “good” reproducibility (ρ = 0.713, < 0.001), and an excellent concordance (ICC = 0.841 Confidence Interval 95% 0.779, 0.885). It can thus be said that the Mini-ECCA displayed acceptable reproducibility and is suitable for the purpose of dietary assessment and guidance.
评估食物摄入量的质量可能有助于制定营养计划。在墨西哥，没有可以快速评估这一变量的筛选工具。本研究旨在确定一种用于评估墨西哥人群食物摄入量质量的迷你调查问卷（Mini-ECCA）的可重复性。Mini-ECCA 由 12 个问题组成，这些问题基于墨西哥和国际上关于食物和非酒精饮料摄入的建议，并附有食物量估计的照片支持。每个问题的得分为 0（不健康）或 1（健康），最终得分需要经过分类程序。通过营养研究框架，邀请了墨西哥瓜达拉哈拉市自来水公司的 152 名员工（2016 年 4 月至 8 月）参与。该调查分两轮（测试和复测）进行，两轮之间间隔 15 天。我们计算了得分分类一致性的 Spearman 相关系数、组内相关系数（ICC）和加权 Kappa（SPSS 认为 < 0.05 具有统计学意义）。该调查显示出了良好的可重复性（ρ=0.713， < 0.001），并且具有极好的一致性（ICC=0.841，95%置信区间为 0.779-0.885）。因此，可以说 Mini-ECCA 具有可接受的可重复性，适合用于饮食评估和指导。
