营养对幼儿的最佳生长发育至关重要。营养风险筛查有助于在营养评估和治疗之后进行早期干预。NutriSTEP(每名学龄前儿童营养筛查工具)是一种有效、可靠的学龄前儿童(3-5岁)营养风险筛查问卷。还发现有必要为幼儿(18-35个月)提供类似的问卷。其目的是开发一种可靠和有效的幼儿营养STEP。幼儿营养STEP发育分4个阶段。内容和面孔效度通过文献综述、父母焦点组(n=6；48名参与者)和专家(n=13)(阶段A)确定。通过对107名父母/照顾者(B阶段)的关键截取访谈，完善了问卷草稿。重测信度(C阶段)，基于组内相关性(ICC)、Kappa(Kappa)统计和Wilcoxon检验，对133名父母/照顾者进行了评估。通过将幼儿NutriSTEP的得分与200名注册营养师(RD)幼儿的综合营养评估进行比较，使用受试者操作特征(ROC)曲线来评估标准有效性(D阶段)。幼儿营养-STEP在两次管理之间具有信度(ICC=0.951，F=20.53，p<；0.001)；大多数问题具有中等(kappa&>=0.6)或极好(kappa&>=0.8)一致性。RD营养风险评分与幼儿营养STEP相关(r=0.67p<；0.000)。中度和高度RD风险评级的ROC曲线下面积分别为84.6%和82.7%。确定了>；=21(敏感度86%；特异度61%)(中危)和>；=26(敏感度95%；特异度63%)(高危)的临界点。幼儿NutriSTEP问卷对幼儿营养风险的筛查既可靠又有效。
Nutrition is vital for optimal growth and development of young children. Nutrition risk screening can facilitate early intervention when followed by nutritional assessment and treatment. NutriSTEP (Nutrition Screening Tool for Every Preschooler) is a valid and reliable nutrition risk screening questionnaire for preschoolers (aged 3-5 years). A need was identified for a similar questionnaire for toddlers (aged 18-35 months). The purpose was to develop a reliable and valid Toddler NutriSTEP. Toddler NutriSTEP was developed in 4 phases. Content and face validity were determined with a literature review, parent focus groups (n = 6; 48 participants), and experts (n = 13) (phase A). A draft questionnaire was refined with key intercept interviews of 107 parents/caregivers (phase B). Test-retest reliability (phase C), based on intra-class correlations (ICC), Kappa (kappa) statistics, and Wilcoxon tests was assessed with 133 parents/caregivers. Criterion validity (phase D) was assessed using Receiver Operating Characteristic (ROC) curves by comparing scores on the Toddler NutriSTEP to a comprehensive nutritional assessment of 200 toddlers with a registered dietitian (RD). The Toddler NutriSTEP was reliable between 2 administrations (ICC = 0.951, F = 20.53, p < 0.001); most questions had moderate (kappa >= 0.6) or excellent (kappa >= 0.8) agreement. Scores on the RD nutrition risk rating and the Toddler NutriSTEP were correlated (r = 0.67, p < 0.000). The area under the ROC curve for moderate and high RD risk ratings were 84.6% and 82.7%, respectively. Cut-points of >= 21 (sensitivity 86%; specificity 61%) (moderate risk) and >= 26 (sensitivity 95%; specificity 63%) (high risk) were determined. The Toddler NutriSTEP questionnaire is both reliable and valid for screening for nutritional risk in toddlers.
