目的24小时回忆法可以获取大量的食物摄入信息，但对偶发性食物的摄入量测量不足。我们探索使用食物频率问卷（FFQ）数据作为统计模型中的协变量，以估计个人偶尔消费食物的通常摄入量及其分布，并描述食物倾向问卷的发展，2003年推出的FFQ-2004年国家健康和营养调查。设计我们分析了965名成年参与者在美国餐桌上吃饭的研究数据，完成了四次24小时召回和一次FFQ。我们评估是否增加FFQ报告的频率与24小时召回消费天数和金额reported.Results为52 56个食物组（93%），218 230个食物（95%），有显着的单调递增关系之间的FFQ频率和24小时召回消费概率。47的56个食物组（84%）和55的230个（24%）个别foods，有显着的正相关性之间的FFQ频率和消费日平均intake.Conclusions，我们发现强大的和一致的关系报告FFQ频率的食物和食物组的消费和消费概率24小时召回。这支持的前提下，频率数据可以提供重要的协变量信息，补充多个召回估计通常摄入的食物组。
Objective Twenty-four- hour recalls capture rich information on food consumption, but suffer from inadequately measuring usual intakes of episodically consumed foods. We explore using food frequency questionnaire (FFQ) data as covariates in a statistical model to estimate individual usual intakes of episodically consumed foods and their distributions and describe the development of the Food Propensity Questionnaire, an FFQ introduced in the 2003-2004 National Health and Nutrition Examination Survey.Design We analyzed data from 965 adult participants in the Eating at America's Table Study who completed four 24-hour recalls and an FFQ. We assessed whether or not increasing FFQ-reported frequency was associated with both number of 24-hour recall consumption days and amounts reported.Results For 52 of 56 food groups (93%), and 218 of 230 individual foods (95%), there were significant monotonically increasing relationships between FFQ frequency and 24-hour recall probability of consumption. For 47 of 56 food groups (84%) and 55 of 230 (24%) individual foods, there were significant positive correlations between FFQ frequencies and consumption-day mean intake.Conclusions We found strong and consistent relationships between reported FFQ frequency of food and food-group consumption and probability of consumption on 24-hour recalls. This supports the premise that frequency data may offer important covariate information in supplementing multiple recalls for estimating usual intake of food groups.
