Assessing food intake is a challenge for researchers given the inherent complexity of the issue. One of the methods used in epidemiological studies is the Food Frequency Questionnaire (FFQ). The scope of this paper was to identify studies that developed and/or validated the FFQ in Brazil, analyzing the methods used and the main results of the validation. The PubMed, LILACS and SciELO databases were researched for studies published prior to 2013 on the development and validation of the FFQ in Brazil. These studies were analyzed according to: i) the main methodological characteristics of the elaboration/validation process of the questionnaires; ii) the key results related to validation. Forty-one studies were assessed: 6 on the development of the FFQ; 18 on the development and validation of the FFQ; 17 on the validation of the FFQ. There were inter-regional differences in the publications and methodological differences in the elaboration and validation of the FFQ. Adults and adolescents were the groups most covered for the validation of the FFQ, though specific studies for children < 5 years of age were not found. The methodological rigor and statistical results guarantee the suitability of the validation of the FFQ for the target populations, with high correlations for energy, carbohydrates, fibers, calcium and vitamin C.
鉴于该问题固有的复杂性，评估食物摄入量对研究人员来说是一项挑战。流行病学研究中使用的方法之一是食物频率问卷（FFQ）。本文的范围是确定在巴西开发和/或验证FFQ的研究，分析所使用的方法以及验证的主要结果。在PubMed、LILACS和SciELO数据库中检索了2013年之前发表的关于巴西FFQ开发和验证的研究。这些研究根据以下方面进行分析：i）问卷编制/验证过程的主要方法学特征；ii）与验证相关的关键结果。评估了41项研究：6项关于FFQ的开发；18项关于FFQ的开发和验证；17项关于FFQ的验证。在FFQ的编制和验证方面，出版物存在地区间差异，方法也存在差异。成年人和青少年是FFQ验证涵盖最多的群体，不过未发现针对5岁以下儿童的具体研究。方法学的严谨性和统计结果保证了FFQ验证对目标人群的适用性，能量、碳水化合物、纤维、钙和维生素C的相关性较高。
