BACKGROUND It is important to find ways to minimize errors when children self-report food consumption. OBJECTIVE The objective of this study was to investigate whether assistance given to children completing a self-administered 24-hour dietary recall instrument called SACANA (Self-Administered Child, Adolescent and Adult Nutrition Assessment) increased the repeatability and plausibility of energy intake (EI) estimates. PARTICIPANTS/SETTING The study was conducted between October 2013 and March 2016 in a convenience sample of 395 children, aged 8 to 17 years, from eight European countries participating in the I.Family study. DESIGN SACANA was used to recall the previous day's food intake, twice in a day, once with and once without assistance. MAIN OUTCOME MEASURES The difference in EI between the first and second recalls was the main repeatability measure; the ratio of EI to basal metabolic rate was the plausibility measure. STATISTICAL METHODS Generalized linear mixed models, adjusted for sex, age, and body mass index z-score, were used to assess whether assistance during the first vs second recall influenced repeatability and plausibility. RESULTS The difference in estimated EI (EI from second recall minus EI from first recall) was significantly lower (P<0.001) in those assisted at first (median=-76 kcal) than those assisted at second recall (median=282 kcal). Modeling showed that EI at assisted first recall was 19% higher (95% CI 1.13 to 1.24) than in assisted second recall. Overall, 60% of recalls had a plausible EI. Modeling to estimate the simultaneous effects of second vs first recall and assistance vs no assistance on plausibility showed that those assisted at first recall had significantly higher odds of a plausible recall than those unassisted (odds ratio 3.64, 95% CI 2.20 to 6.01), with no significant difference in plausibility of second recall compared to the first (odds ratio 1.48, 95% CI 0.92 to 2.35). CONCLUSIONS When children are assisted at first recall, the plausibility and repeatability of the later unassisted recall improve. This improvement was evident for all ages. A future, adequately powered study is required to investigate the age range for which assistance is advisable.

为儿童和青少年提供帮助是否会增加使用基于网络的饮食召回工具进行自我报告的可重复性和合理性？

背景 当儿童自我报告食物消费时，找到最小化错误的方法很重要。目的 本研究的目的是调查对完成名为 SACANA（自我管理的儿童、青少年和成人营养评估）的儿童进行自我管理的 24 小时饮食回忆工具的帮助是否增加了能量摄入 (EI) 的可重复性和合理性估计。参与者/设置 该研究是在 2013 年 10 月至 2016 年 3 月期间在一个便利样本中进行的，该样本包括来自参与 I.Family 研究的八个欧洲国家的 395 名 8 至 17 岁儿童。DESIGN SACANA 用于回忆前一天的食物摄入量，一天两次，一次有帮助，一次没有帮助。主要结果测量第一次和第二次召回之间的 EI 差异是主要的可重复性测量；EI 与基础代谢率的比率是可信度的衡量标准。统计方法 根据性别、年龄和体重指数 z 分数调整的广义线性混合模型用于评估第一次和第二次回忆期间的帮助是否影响可重复性和合理性。结果 最初接受帮助的人（中位数=-76 kcal）的估计 EI（第二次召回的 EI 减去第一次召回的 EI）的差异显着低于（P<0.001），比第二次召回时获得协助的人（中位数 = 282 kcal）显着更低（P<0.001）。建模显示，辅助第一次回忆时的 EI 比辅助第二次回忆高 19%（95% CI 1.13 至 1.24）。总体而言，60% 的召回具有合理的 EI。用于估计第二次与第一次回忆以及帮助与无帮助对似真性的同时影响的建模表明，那些在第一次回忆时得到帮助的人比没有帮助的人有明显更高的似是而非的回忆（优势比 3.64，95% CI 2.20 至 6.01），与与第一次相比，第二次回忆的可信度没有显着差异（优势比 1.48，95% CI 0.92 至 2.35）。结论 当儿童在第一次回忆时得到帮助，后来无帮助回忆的可信度和可重复性得到改善。这种改善在所有年龄段都很明显。未来需要进行足够有力的研究来调查建议提供援助的年龄范围。
