Assessing food intake of pregnant women is extremely important, because maternal dietary patterns can influence fetal development as well as have either positive or negative effects on both the mother and fetus. Thus, the aim of the present study was to carry out a systematic review of the literature on food frequency questionnaires developed and validated for pregnant women, in order to assess their methodological quality and validation process.
A systematic review of studies focused on validating food frequency questionnaires for pregnant women was carried out in the PubMed, Embase, Scopus, LILACS, and OpenGrey databases. The selected studies were assessed based on their correlation coefficient in validation and reproducibility analyses, whereas their methodological quality was assessed based on the scoring system proposed by the EURopean micronutrient RECommendations Aligned Network of Excellence.
In total, 10 965 articles were identified in these databases; among them, 14 studies, with sample sizes ranging from 46 to 221 participants, and with participants (pregnant women) at a mean age of 28.68 ± 4.34 y, were selected. Most of the included studies used the 24-h food recall as the method for developing the food list (n = 6), with composition ranging from 46 to 255 items. With respect to the methodological assessment of the selected articles, half of the assessed tools were classified as having excellent methodological quality; their validation and reproducibility correlation coefficients were classified as moderate and high (r ≥ 0.40).
Food frequency questionnaires developed for pregnant women appear to be reliable tools to assess food intake by this group. Overall, they had good methodological quality and adequate correlation coefficients compared with reference methods.
评估孕妇的食物摄入量非常重要，因为母体的饮食模式会影响胎儿的发育，对母亲和胎儿都有积极或消极的影响。因此，本研究旨在对专为孕妇制定和验证的食物频率问卷进行系统评价，以评估其方法学质量和验证过程。
在 PubMed、Embase、Scopus、LILACS 和 OpenGrey 数据库中对专门针对孕妇的食物频率问卷进行了系统评价。根据验证和再现性分析中的相关系数对所选研究进行评估，根据 EURopean micronutrient RECommendations Aligned Network of Excellence 提出的评分系统评估其方法学质量。
在这些数据库中，共确定了 10965 篇文章；其中，有 14 项研究，样本量从 46 到 221 例，参与者（孕妇）的平均年龄为 28.68 ± 4.34 岁，被选中。大多数纳入的研究使用 24 小时食物回忆作为食物清单的开发方法（n = 6），组成部分从 46 到 255 项不等。就所选文章的方法学评估而言，有一半的评估工具被归类为具有优秀的方法学质量；它们的验证和再现性相关系数被归类为中等和高度（r ≥ 0.40）。
专为孕妇设计的食物频率问卷似乎是评估该人群食物摄入量的可靠工具。总体而言，它们的方法学质量良好，与参考方法相比，相关性系数也足够。
