There are few short, validated tools to assess young children's obesity-related dietary behaviours, limiting the rapid screening of dietary behaviours in research and practice-based early obesity prevention. This study aimed to develop and assess the reliability and validity of a caregiver-reported short dietary questionnaire to rapidly assess obesity-related dietary behaviours in children aged 6 months to 5 years. The Early Prevention of Obesity in Childhood Dietary Questionnaire (EPOCH-DQ) was developed using a rigorous process to determine content and structural validity. Three age-appropriate versions were developed for (1) infants, aged 6-12 months, (2) toddlers, aged 1-2.9 years and (3) pre-schoolers, aged 3-5 years. The questionnaire (7-15 items) measures dietary behaviours, including diet risk from non-core food and beverage intake, diet quality from vegetable frequency, bread type and infant feeding practices. Test-retest reliability was assessed from repeated administrations 1 week apart (n = 126). Internal consistency, concurrent validity (against a comparison questionnaire, the InFANT Food Frequency Questionnaire), construct validity and interpretability were assessed (n = 209). Most scores were highly correlated and significantly associated (p < 0.05) for validity (r: 0.45-0.89, percentage agreement 68%-100%) and reliability (intraclass correlation coefficient: 0.61-0.99) for diet risk, diet quality and feeding practice items. The EPOCH-DQ shows acceptable validity and reliability for screening of obesity-related behaviours of children under 5 years of age. The short length and, thus, low participant burden of the EPOCH-DQ allows for potential applications in various settings. Future testing of the EPOCH-DQ should evaluate culturally and socio-economically diverse populations and establish the predictive validity and sensitivity to detect change.
用于评估幼儿肥胖相关饮食行为的简短、经过验证的工具很少，这限制了在研究和基于实践的早期肥胖预防中快速筛查饮食行为。本研究旨在开发和评估一种 caregiver 报告的简短饮食问卷，以快速评估 6 个月至 5 岁儿童肥胖相关的饮食行为。使用严格的过程开发了早期预防儿童肥胖饮食问卷（EPOCH-DQ），以确定内容和结构的有效性。开发了三个适用于不同年龄段的版本：（1）6-12 个月大的婴儿，（2）1-2.9 岁的幼儿，以及（3）3-5 岁的学龄前儿童。该问卷（7-15 个项目）测量饮食行为，包括非核心食物和饮料摄入的饮食风险、蔬菜频率、面包类型和婴儿喂养实践的饮食质量。通过间隔一周重复进行两次测试来评估测试-重测信度（n=126）。还评估了内部一致性、同时效度（与对照问卷，即 InFANT 食物频率问卷）、结构有效性和可解释性（n=209）。大多数分数的相关性很高，并且有效性（r：0.45-0.89，百分比一致性 68%-100%）和可靠性（组内相关系数：0.61-0.99）的得分高度相关且显著相关（p<0.05）。与饮食风险、饮食质量和喂养实践项目。EPOCH-DQ 显示出可接受的有效性和可靠性，可用于筛查 5 岁以下儿童肥胖相关行为。EPOCH-DQ 的简短长度，因此，参与者负担较低，允许在各种环境中潜在应用。未来应该测试 EPOCH-DQ 在文化和社会经济多样化的人群中的预测有效性和检测变化的敏感性。
