In order to rapidly assess nutrient intake, Food Frequency Questionnaires (FFQ) have been developed and proven to be reliable for quick, user friendly analysis in adults. However, the accuracy of these questionnaires in children has been studied to a limited extent. The aim of this study was to compare the daily calcium intake values obtained from the Rapid Assessment Method (RAM), an FFQ, for assessing daily calcium intake in child and adolescent males with the values obtained from the 24-hour recall method.
Subjects included 162 child and adolescent males, aged 9-16 years, subdivided into elementary school (ES, 9-12 years) and high school (HS, 14-16 years) age groups.
Daily calcium intake was significantly lower in ES compared with HS, using both methods. The intra-class correlation coefficients (ICC) between RAM values and those obtained using the 24-hour recall questionnaire were significant yet moderate (ICC = 0.46 and 0.43 for ES and HS, respectively). However, daily calcium intake obtained using RAM was significantly higher when compared with the 24-hour recall values in both ES (1576 +/- 1101 vs. 1003 +/- 543 mg, in RAM and 24-hour, respectively) and in HS males (1873 +/- 739 vs. 1159 +/- 515 mg, in RAM and 24-hour, respectively).
RAM overestimates daily calcium intake as compared with the 24-hour recall method in both child and adolescent males.
为了快速评估营养摄入量，已经开发了食物频率问卷（FFQ），并已证明其在成人中进行快速、用户友好的分析时是可靠的。然而，这些问卷在儿童中的准确性研究程度有限。本研究的目的是比较通过快速评估方法（RAM，一种FFQ）获得的儿童和青少年男性每日钙摄入量值与通过24小时回顾法获得的值。
受试者包括162名9至16岁的儿童和青少年男性，分为小学（ES，9至12岁）和高中（HS，14至16岁）年龄组。
使用两种方法时，ES组的每日钙摄入量均显著低于HS组。RAM值与使用24小时回顾问卷获得的值之间的组内相关系数（ICC）显著但适中（ES组和HS组的ICC分别为0.46和0.43）。然而，在ES组（RAM法为1576±1101毫克，24小时回顾法为1003±543毫克）和HS组男性（RAM法为1873±739毫克，24小时回顾法为1159±515毫克）中，使用RAM法获得的每日钙摄入量均显著高于24小时回顾值。
与24小时回顾法相比，RAM法高估了儿童和青少年男性的每日钙摄入量。
