INTRODUCTION/OBJECTIVE: In Asia, 42% of young children suffer from iron deficiency anemia. Children have an increased requirement for iron intake because of growth and physical activity. Education plays an important role in anemia prevention and in ensuring children are aware of appropriate iron intake and the iron content of different foods. As a tool for this purpose, we adapted the adult version of the Revised Iron Intake Scale (RIIS) to create the Child and Adolescent Version of the Iron Intake Scale (CIIS), using illustrations to help children recognize the foods listed in the CIIS. We aimed to evaluate the validity and reliability of this new scale.
We conducted a cross-sectional study using a self-administered questionnaire to examine the criterion-related validity of the CIIS. We used Spearman's rank correlation coefficient to compare iron intake estimated by the CIIS with that calculated by the Brief-type Diet History Questionnaire (BDHQ-15y), which assesses respondents' dietary habits over the past month and is standardized among Japanese children. The survey was repeated twice to examine reliability.
We found a moderate positive correlation for iron intake between the CIIS and BDHQ-15y, with a correlation coefficient of .52 (n = 258, < .001). Cronbach's alpha coefficient was .718. The CIIS reproducibility test yielded a correlation coefficient of .67.
Our results indicated that the CIIS was valid, reliable, and reproducible. We therefore believe that the scale can be used to improve education about iron deficiency anemia and thereby reduce anemia rates among children and adolescents.
简介/目的：在亚洲，42%的幼儿患有缺铁性贫血。由于生长和身体活动，儿童对铁的摄入量有更高的要求。教育在预防贫血和确保儿童了解适当的铁摄入量以及不同食物中的铁含量方面发挥着重要作用。为此，我们改编了成人版修订铁摄入量量表（RIIS），创建了儿童和青少年版铁摄入量量表（CIIS），并使用插图帮助儿童识别 CIIS 中列出的食物。我们旨在评估该新量表的有效性和可靠性。
我们进行了一项横断面研究，使用自我管理问卷来检验 CIIS 的效标关联效度。我们使用 Spearman 等级相关系数来比较 CIIS 估计的铁摄入量和 Brief-type 饮食史问卷（BDHQ-15y）计算的铁摄入量，后者评估受访者过去一个月的饮食习惯，并在日本儿童中标准化。调查重复了两次，以检验可靠性。
我们发现 CIIS 和 BDHQ-15y 之间的铁摄入量存在中度正相关，相关系数为.52（n=258， < .001）。Cronbach's alpha 系数为.718。CIIS 可重复性测试的相关系数为.67。
我们的结果表明 CIIS 具有有效性、可靠性和可重复性。因此，我们认为该量表可用于改善缺铁性贫血教育，从而降低儿童和青少年的贫血率。
