To describe the design of a Food Frequency Questionnaire (FFQ) to be used in studies on food intake of adults from Cuiabá, Mato Grosso State, Brazil.
A 24-hour dietary recall (24hR) was applied to a sub-sample of 104 men and women, randomly selected from a random population-based study sample. Based on the frequency of report and on the contribution to the intake of energy and nutrients in the 24hR, 81 food items and respective reference servings were selected to comprise the FFQ food list. Reference portions were defined based on the most reported portion sizes in the 24-hour dietary recalls. The FFQ list was associated to eight options of intake frequency.
Sugar, coffee, beans, rice, beef, bread, and soda were cited by at least 50% of the interviewed group and the latter four foods were the ones that most contributed to energy intake. There were no differences among men and women related to the foods that provided most macro and micronutrients.
The FFQ included the most relevant food items involved in the food habits of the adult population from Cuiabá, Mato Grosso. Once the validity and reproducibility of this tool are proven, it will be useful in epidemiologic and clinical investigations on the role of diet on disease development in the target population.
描述一种食物频率问卷（FFQ）的设计，该问卷将用于巴西马托格罗索州库亚巴市成年人食物摄入量的研究。
对从基于人群的随机研究样本中随机抽取的104名男性和女性子样本进行了24小时膳食回顾（24hR）。根据报告频率以及在24hR中对能量和营养素摄入的贡献，选择了81种食物及其相应的参考份量，以构成FFQ食物清单。参考份量是根据24小时膳食回顾中报告最多的份量大小来定义的。FFQ清单与八种摄入频率选项相关联。
至少50%的受访群体提到了糖、咖啡、豆类、大米、牛肉、面包和汽水，后四种食物对能量摄入的贡献最大。在提供大多数常量和微量营养素的食物方面，男性和女性之间没有差异。
FFQ纳入了马托格罗索州库亚巴市成年人群饮食习惯中最相关的食物项目。一旦证明该工具的有效性和可重复性，它将有助于针对目标人群中饮食对疾病发展作用的流行病学和临床调查。
