目的评价食物摄入量记录软件系统（FIRSSt）对学校午餐和24小时膳食回忆（24 hDR）观察的有效性;并检验排序、观察和头发样本作为假管道对膳食报告准确性的影响。（FIRSSt vs 24 hDR），观察学校午餐，头发样本作为假管道操作，随机分配参与者。受试者/设置138名四年级学生在2所小学。主要结果测量报告的食物消费的准确性，和遗漏之间的FIRSSt，24 hDR，并在学校午餐观察。统计分析采用t检验、Pearson相关分析、方差分析、因子分析等方法。240/o入侵，30%的遗漏率。而营养师进行的24 hDR获得了59%的匹配率，17%的侵入率和24%的遗漏率。在前一天的所有膳食中，FIRSSt达到60%的匹配率、15%的侵入率和24%的遗漏率。没有证据表明评估顺序影响准确性指标，但学校午餐观察对入侵百分比的影响很弱。获得毛发样本降低了FIRSS t与24 hDR的遗漏率，并增加了24 hDR与观察的匹配率，从而增强了这一伪流水线程序。孩子们普遍喜欢完成第一个。西班牙裔儿童更有可能使用FIRSSt.Applications/conclusions报告问题FIRSSt是有点不太准确，比营养师进行的24小时DR。然而，这种成本较低的程序为评估儿童饮食提供了一种有前途的方法。观察学校午餐的消耗量可能是反应性的，人为地增加了一致性。获取头发样本作为一个假的管道可能是一个有价值的技术，以提高儿童饮食评估的准确性。
Objectives To assess the validity of the Food Intake Recording Software System (FIRSSt) against observation of school lunch and a 24-hour dietary recall (24hDR); and to test the effects of sequencing, observation and a hair sample as a bogus pipeline on accuracy of dietary report.Design Six-group design systematically varying sequence of self-report (FIRSSt vs 24hDR), observation of school lunch, and hair sample as a bogus pipeline manipulation, with random assignment of participants.Subjects/setting 138 fourth-grade students in 2 elementary schools.Main outcome measures accuracy of reported food consumption was measured in terms of snatches, intrusions, and omissions among the FIRSSt, 24hDR, and as observed at school lunch. Students also completed self-report of performance with FIRSSt.Statistical analysis performed t tests, Pearson correlations, analysis of variance, factor analysis.Results When compared with school lunch observation for one meal, FIRSSt attained 46% match. 240/o intrusion, and 30% omission rates. while a dietitian-conducted 24hDR obtained 59% match, 17% intrusion, and 24% omission rates. FIRSSt attained 60% match, 15% intrusion, and 24, omission rates against 24hDR for all meals in the previous day. There was no evidence of sequence of assessment affecting accuracy indicators, but there was a weak effect of school lunch observation on percent intrusions. Obtaining a hair sample reduced the omission rate for FIRSSt vs 24hDR anti increased the match rate for 24hDR vs observation, thereby enhancing this as a bogus pipeline procedure. Children generally enjoyed completing FIRSSt. Hispanic children were more likely to report problems using FIRSSt.Applications/conclusions FIRSSt is somewhat less accurate than a dietitian-conducted 24hDR. However, this lower-cost procedure provides a promising method for assessing diet among children. Observation of consumption at school lunch may he reactive and artificially increase agreement. Obtaining a hair sample as a bogus pipeline may be a valuable technique for enhancing the accuracy of dietary assessment among children.
