该次要分析研究了体重指数（BMI）类别和性别对多次24小时饮食回忆期间报告准确性的影响。在三个场合，79名儿童（40名女孩，39名男孩）中的每一个都被观察到吃学校餐，然后在第二天早上采访前一天的摄入量，任何两个连续场合之间的25天或更长时间。使用年龄/性别BMI量表，我们将48名儿童归类为健康体重（>= 5但<85百分位数），14名儿童有超重风险（>= 85但<95百分位数），17名儿童超重（>= 95百分位数）。对5个结果中的每一个进行重复测量分析（观察到的进食项目数、报告的进食项目数、遗漏率、侵入率和总不准确度）。对于观察到的项目，BMI X类试验相互作用是轻微显著的（P = 0.079）;在试验中，这个结果对于健康体重的儿童是稳定的，对于有超重风险的儿童是下降和稳定的，对于超重儿童是稳定和下降的。这一结果在超重儿童中最大，在健康体重儿童中最小（P = 0.015）。对于遗漏率（P = 0.028）和侵入率（P = 0.083），BMI类别x试验相互作用显著且边缘显著;在试验中，健康体重儿童的BMI类别x试验相互作用均降低，超重风险儿童的BMI类别x试验相互作用降低并稳定，超重儿童的BMI类别x试验相互作用增加并稳定。总的不准确性在试验中略有下降（P = 0.076）;男孩的这一结果大于女孩（P = 0.049）。结果表明，儿童的饮食报告准确性在多次回忆中因BMI类别而异。需要对每个BMI类别、性别和种族进行足够样本的验证研究。(c)2006年爱思唯尔公司All rights reserved.
This secondary analysis investigated the influences of body mass index (BMI) category and sex on reporting accuracy during multiple 24-hour dietary recalls. On 3 occasions, each of 79 children (40 girls, 39 boys) was observed eating school meals and then interviewed the next morning about the previous day's intake, with 25 days or more between any 2 consecutive occasions for a child. Using age/sex BMI percentiles, we categorized 48 children as having a healthy weight (>= 5th but < 85th percentile), 14 as at risk of being overweight (>= 85th but < 95th percentile), and 17 as overweight (>= 95th percentile). A repeated-measures analysis was conducted for each of 5 outcomes (number of items observed eaten, number of items reported eaten, omission rate, intrusion rate, and total inaccuracy). For items observed, the BMI Category X Trial interaction was marginally significant (P = .079); over trials, this outcome was stable for children with a healthy weight, decreased and stabilized for children at risk of being overweight, and stable and decreased for overweight children. This outcome was greatest for overweight children and least for children with a healthy weight (P = .015). For items reported, no significant effect was found. For omission rate (P = .028) and intrusion rate (P = .083), the BMI Category x Trial interaction was significant and marginally significant; over trials, both decreased for children with a healthy weight, decreased and stabilized for children at risk of being over-weight, and increased and stabilized for over-weight children. Total inaccuracy decreased slightly over trials (P = .076); this outcome was greater for boys than for girls (P = .049). The results suggest that children's dietary reporting accuracy over multiple recalls varies by BMI category. Validation studies with adequate samples for each BMI category, sex, and race are needed.
