Robust measurement of dietary intake in population studies of children is critical to better understand the diet–health nexus. It is unknown whether parent proxy-report of children’s dietary intake through online 24-h recalls is feasible in large cohort studies. The primary objective of this study was to describe the feasibility of the Automated Self-Administered 24-h Dietary Assessment Tool (ASA24) to measure parent proxy-reported child dietary intake. A secondary objective was to compare intake estimates with those from national surveillance. Parents of children aged 4–15 years participating in the TARGet Kids! research network in Toronto, Canada were invited by email to complete an online ASA24-Canada-2016 recall for their child, with a subsample prompted to complete a second recall about 2 weeks later. Descriptive statistics were reported for ASA24 completion characteristics and intake of several nutrients. Comparisons were made to the 2015 Canadian Community Health Survey (CCHS) 24-h recall data. A total of 163 parents completed the first recall, and 46 completed the second, reflecting response rates of 35% and 59%, respectively. Seven (4%) first recalls and one (2%) second recall were excluded for ineligibility, missing data, or inadvertent parental self-report. The median number of foods reported on the first recall was 18.0 (interquartile range (IQR) 6.0) and median time to complete was 29.5 min (IQR 17.0). Nutrient intakes for energy, total fat, protein, carbohydrates, fiber, sodium, total sugars, and added sugars were similar across the two recalls and the CCHS. The ASA24 was found to be feasible for parent proxy-reporting of children’s intake and to yield intake estimates comparable to those from national surveillance, but strategies are needed to increase response rate and support completion to enhance generalizability.

自动自我管理 24 小时饮食评估工具 (ASA24) 召回，用于家长代理报告儿童摄入量（> 4 岁）：可行性研究


在儿童人口研究中对饮食摄入量的稳健测量对于更好地了解饮食与健康的关系至关重要。目前尚不清楚，在大型队列研究中，家长通过在线 24 小时回忆来代理报告儿童饮食摄入量是否可行。本研究的主要目的是描述自动自我管理 24 小时饮食评估工具 (ASA24) 测量家长代理报告的儿童饮食摄入量的可行性。第二个目标是将摄入量估计值与国家监测数据进行比较。参加 TARGet Kids 的 4-15 岁儿童的家长！加拿大多伦多的研究网络受电子邮件邀请为其孩子完成在线 ASA24-Canada-2016 召回，并提示子样本在大约两周后完成第二次召回。报告了 ASA24 完成特征和几种营养素摄入量的描述性统计数据。与 2015 年加拿大社区健康调查 (CCHS) 24 小时召回数据进行了比较。共有 163 名家长完成了第一次召回，46 名家长完成了第二次召回，回应率分别为 35% 和 59%。七次 (4%) 第一次召回和一次 (2%) 第二次召回因不合格、数据缺失或无意的家长自我报告而被排除。首次召回时报告的食品数量中位数为 18.0（四分位距 (IQR) 6.0），完成时间中位数为 29.5 分钟（IQR 17.0）。两次召回和 CCHS 中的能量、总脂肪、蛋白质、碳水化合物、纤维、钠、总糖和添加糖的营养摄入量相似。 研究发现 ASA24 对于家长代理报告儿童摄入量是可行的，并产生与国家监测结果相当的摄入量估计值，但需要采取策略来提高答复率和支持完成率，以增强普遍性。
