Summarize the validity and reliability of child/adolescent food frequency questionnaires (FFQs) that assess food and/or food groups.
We performed a systematic review of child/adolescent (6-18 years) FFQ studies published between January 2001 and December 2010 using MEDLINE, Cochrane Library, PsycINFO, and Google Scholar. Main inclusion criteria were peer reviewed, written in English, and reported reliability or validity of questionnaires that assessed intake of food/food groups. Studies were excluded that focused on diseased people or used a combined dietary assessment method. Two authors independently selected the articles and extracted questionnaire characteristics such as number of items, portion size information, time span, category intake frequencies, and method of administration. Validity and reliability coefficients were extracted and reported for food categories and averaged across food categories for each study.
Twenty-one studies were selected from 873, 18 included validity data, and 14 included test-retest reliability data. Publications were from the United States, Europe, Africa, Brazil, and the south Pacific. Validity correlations ranged from 0.01 to 0.80, and reliability correlations ranged from 0.05 to 0.88. The highest average validity correlations were obtained when the questionnaire did not assess portion size, measured a shorter time span (ie, previous day/week), was of medium length (ie, ≈ 20-60 items), and was not administered to the child's parents.
There are design and administration features of child/adolescent FFQs that should be considered to obtain reliable and valid estimates of dietary intake in this population.
总结评估食物和/或食物组的儿童/青少年食物频率问卷（FFQ）的有效性和可靠性。
我们对 2001 年 1 月至 2010 年 12 月期间发表的儿童/青少年（6-18 岁）FFQ 研究进行了系统评价，使用了 MEDLINE、Cochrane 图书馆、PsycINFO 和 Google Scholar。主要纳入标准是同行评议、英文写作，并报告了评估食物/食物组摄入量的问卷的可靠性或有效性。排除了关注患病人群或使用综合膳食评估方法的研究。两位作者独立选择文章，并提取问卷特征，如项目数量、份量信息、时间跨度、类别摄入频率和管理方法。提取并报告了每个研究的食物类别有效性和可靠性系数，并对每个研究的食物类别进行平均。
从 873 篇中选择了 21 篇研究，其中 18 篇包含有效性数据，14 篇包含重测信度数据。出版物来自美国、欧洲、非洲、巴西和南太平洋。有效性相关性范围从 0.01 到 0.80，可靠性相关性范围从 0.05 到 0.88。当问卷不评估份量、测量较短的时间跨度（即前一天/周）、长度适中（即约 20-60 项）且不由儿童的父母管理时，获得的平均有效性相关性最高。
在评估该人群的膳食摄入量时，应考虑儿童/青少年 FFQ 的设计和管理特点，以获得可靠和有效的估计值。
