背景与目的：本研究的目的是评价食物频率问卷（FFQ）的可重复性和有效性，并探讨该问卷的方法学框架。方法与结果：半定量FFQ包括69个问题，涉及所有主要食品类别和通常消费的饮料的消费频率，7个问题涉及饮食行为。500人（37 +/- 15岁，38%男性）被招募进行重复性过程，另外432人（46 +/- 16岁，40%男性）也完成了3天日记（3DD）以进行验证过程。所有被测食品（Kendall's tau-b: 0.26-0.67, p < 0.05）、能量和大量营养素摄入（能量校正相关系数为0.56-0.69,p < 0.05）的FFQ重复性均良好。“乳制品”、“水果”、“酒精”和“兴奋剂”的FFQ具有中等效度（tau-b: 0.31-0.60, p < 0.05），而“淀粉制品”、“豆类”、“蔬菜”、“肉类”、“鱼类”、“糖果”、“鸡蛋”、“油脂”的FFQ一致性较低（tau-b < 0.30, p < 0.05）。FFQ在能量和常量营养素摄入量方面也是有效的。性别和BMI类别（<或>= 25 kg/m(2)）的敏感性分析显示，FFQ对所有食物组（除了“脂肪和油”摄入量）以及能量和营养摄入量具有相似的有效性。结论：所提出的FFQ可重复且相对有效，因此可用于营养评估目的。(C) 2010 Elsevier b.v.保留所有权利。
Background and Aim: The aim of this work was to evaluate the repeatability and the validity of a food frequency questionnaire (FFQ), and to discuss the methodological framework of such procedures.Methods and Results: The semi-quantitative FFQ included 69 questions regarding the frequency of consumption of all main food groups and beverages usually consumed and 7 questions regarding eating behaviors. Five hundred individuals (37 +/- 15 yrs, 38% males) were recruited for the repeatability process, while another 432 (46 +/- 16 yrs, 40% males) also completed 3-Day Diaries (3DD) for the validation process. The repeatability of the FFQ was adequate for all food items tested (Kendall's tau-b: 0.26-0.67, p < 0.05), energy and macro-nutrients intake (energy adjusted correlation coefficients ranged between 0.56-0.69, p < 0.05). Moderate validity of the FFQ was observed for "dairy products", "fruit", "alcohol" and "stimulants" (tau-b: 0.31-0.60, p < 0.05), whereas low agreement was shown for "starchy products", "legumes", "vegetables", "meat", "fish", "sweets", "eggs", "fats and oils" (tau-b < 0.30, p < 0.05). The FFQ was also valid regarding energy and macronutrients intake. Sensitivity analyses by sex and BMI category (< or >= 25 kg/m(2)) showed similar validity of the FFQ for all food groups (apart from "fats and oils" intake), as well as energy and nutrient intake.Conclusion: The proposed FFQ has proven repeatable and relatively valid for foods' intake, and could therefore be used for nutritional assessment purposes.
