除了消费频率之外，食物频率调查问卷还可以评估消费量，通常通过使用食物模型和饮食稳定性来评估。在美国新墨西哥州正在进行的一项基于人群的肺癌病例对照研究中，对 130 例病例和 309 例对照进行了针对预制维生素 A 和 β-胡萝卜素的食物频率访谈。该问卷测量了 55 种食品的消费频率、数量和稳定性。对这 3 类问题的不同回答组合用于计算维生素 A 总消耗量指数。仅基于频率的指数具有最低值，并且当数量与频率相结合时显着增加。考虑过去的消费对摄入量的绝对和相对估计影响相对较小。指数对之间的斯皮尔曼排序相关性很高。当[流行病学]数据收集的目的是确定受试者特定营养素的相对摄入量时，单独使用频率是合适的。
In addition to frequency of consumption, a food frequency questionnaire may assess amount consumed, often by using food models and the stability of diet. A food frequency interview directed at preformed vitamin A and beta-carotene was administered to 130 cases and 309 controls in an ongoing population-based case-control study of lung cancer in New Mexico [USA]. The questionnaire measured frequency amount and stability of consumption for 55 food items. Different combinations of responses to these 3 types of questions were used to calculate indices of total vitamin A consumption. The index based on frequency alone had the lowest value and increased significantly when amount was combined with frequency. Consideration of past consumption had relatively little effect on absolute and relative estimates of intake. Spearman rank order correlations between index pairs were high. The use of frequency alone is appropriate when the objective of [epidemiological] data collection is to establish subjects'' relative intake of specific nutrients.
