目的：通过访谈内容（仅饮食或饮食和体力活动）、保留间隔（当天或前一天）和年级（第三或第五）来调查饮食回忆准确性的差异。方法：观察 32 名儿童吃学校提供的膳食，每人访谈一次；访谈内容和保留间隔随机分配。对遗漏（观察到但未报告的食品）和侵入（报告但未观察到的食品）率进行多变量方差分析；自变量：访谈内容、保留间隔、成绩。结果：准确性因保留间隔而异（P = .05；当天[遗漏率、侵入率：28%、20%] 优于前一天 [54%、45%]），但访谈内容则不同（P > .48；仅饮食：41%、33%；饮食和体力活动：41%、33%）或等级（P > .27；第三：48%， 42%；第五：34%、24%）。结论和启示：虽然小样本限制了结论的确定性，但结果为提高准确性提供了基于证据的方向：具体来说，缩短保留间隔。更大规模的验证研究需要调查访谈内容、保留间隔和等级对准确性的综合影响。
Objective: Investigate differences in dietary recall accuracy by interview content (diet only or diet and physical activity), retention interval (same day or previous day), and grade (third or fifth).Methods: Thirty-two children observed eating school-provided meals and interviewed once each; interview content and retention interval randomly assigned. Multivariate analysis of variance on rates for omissions (foods observed but unreported) and intrusions (foods reported but unobserved); independent variables: interview content, retention interval, grade.Results: Accuracy differed by retention interval (P = .05; better for same day [omission rate, intrusion rate: 28%, 20%] than previous day [54%, 45%]) but not interview content (P > .48; diet only: 41%, 33%; diet and physical activity: 41%, 33%) or grade (P > .27; third: 48%, 42%; fifth: 34%, 24%).Conclusions and Implications: Although the small sample limits firm conclusions, results provide evidence-based direction to enhance accuracy: specifically, to shorten the retention interval. Larger validation studies need to investigate the combined effect of interview content, retention interval, and grade on accuracy.
