目的：研究1：通过将得分与专家评分进行比较，建立每个学龄前儿童营养筛查工具（NutriSTEP）得分的有效性，该工具是一种基于社区的家长管理的评估营养风险的筛查工具。研究2：验证NutriSTEP的重测信度。研究对象/方法：研究1:269名学龄前儿童家长（从社区招募294名家长）填写NutriSTEP问卷；一名注册营养师（RD）评估了这些学龄前儿童的营养状况（基于医疗和营养史、3天的饮食回忆和人体测量），并对他们的营养风险进行了评级（1（低）至10（高风险））。采用受试者工作特征（ROC）曲线建立效度，并根据敏感性和特异性确定合适的切点。研究2:140名学龄前儿童的父母（其中161名被招募）在两次情况下完成了NutriSTEP。用类内相关（Intraclass correlation， ICC）和kappa来评估信度。结果：研究1:NutriSTEP评分与RD评分呈显著相关（r = 0.48, P = 0.01）。高风险RD评分（8 +分）和中度RD评分（5 +分）的ROC曲线下面积分别为81.5%和73.8%。中度风险分界点为420分，高风险分界点为425分。研究2：不同用药组间的NutriSTEP评分是可靠的（ICC = 0.89, F = 16.7, P0.5）或极优（kappa>0.75）一致性。结论：NutriSTEP问卷是确定学龄前儿童营养风险的有效和可靠的方法。
Objectives: Study 1: To establish the validity of scores on Nutrition Screening Tool for Every Preschooler (NutriSTEP), a community-based parent-administered screening tool for assessing nutrition risk, by comparing scores to an expert rating. Study 2: To demonstrate test -retest reliability of NutriSTEP.Subjects/Methods: Study 1: Parents of 269 preschoolers (of 294 parents recruited from the community), completed the NutriSTEP questionnaire; a registered dietitian (RD) assessed the nutritional status (based on medical and nutritional history, 3 days of dietary recall and anthropometric measurements) of these preschoolers and rated their nutritional risk (1 (low) to 10 (high risk)). Receiver operating characteristic (ROC) curves were used to establish validity and determine appropriate cut points based on sensitivity and specificity. Study 2: Parents of 140 preschoolers (of 161 recruited) completed NutriSTEP on two occasions. Intraclass correlation (ICC) and kappa were used to assess reliability.Results: Study 1: Scores on NutriSTEP and the RD rating were correlated (r = 0.48, P = 0.01). Area under the ROC curve for the high risk RD rating (score 8 +) and the moderate risk rating (score 5 +) were 81.5 and 73.8%, respectively. A moderate risk cut point of 420 and high risk cut point of 425 were identified for the NutriSTEP scores. Study 2: The NutriSTEP score was reliable between administrations (ICC = 0.89, F = 16.7, P0.5) or excellent (kappa>0.75) agreement.Conclusions: The NutriSTEP questionnaire is both valid and reliable for determining nutritional risk in preschoolers.
