Reliable and valid measurements of meat intake are needed to advance understanding of its health effects and to evaluate interventions to reduce meat consumption. Here, we describe the development and reliability of the Oxford Meat Frequency Questionnaire (MFQ). It asks individuals to report the number of servings of meat and seafood products they consumed in the last 24 h and is administered daily over 7 days. The MFQ combines food portion size data from the UK Food Standards Agency with estimates of meat content in composite dishes from the UK's National Diet and Nutrition Survey. Adults who self-reported to eat meat ( = 129) completed a 3-week web-based test-retest reliability study assessing the MFQ twice, with a wash-out week in the middle. Two-way random intraclass correlation coefficients (ICC) revealed moderate to good agreement on all meat outcomes (total meat ICC = 0.716; minimum-maximum individual components = 0.531-0.680), except for fish and seafood (ICC = 0.257). Participants reported finding the questionnaire easy to use and, on average, completed it in less than 2 min. This new MFQ offers a quick, acceptable, and reliable method to measure changes in an individual's meat intake in a UK population.
为了加深对肉类摄入对健康影响的理解，并评估减少肉类消费的干预措施，需要对肉类摄入量进行可靠且有效的测量。在此，我们描述了牛津肉类频率问卷（MFQ）的开发过程及其可靠性。该问卷要求个体报告他们在过去24小时内食用的肉类和海鲜产品份数，并在7天内每天进行填写。MFQ将英国食品标准局的食物份量数据与英国国家饮食与营养调查中复合菜肴的肉类含量估计相结合。自我报告吃肉的成年人（n = 129）完成了一项为期3周的基于网络的重测信度研究，对MFQ进行了两次评估，中间有一周的洗脱期。双向随机组内相关系数（ICC）显示，除鱼类和海鲜外（ICC = 0.257），所有肉类指标均具有中度至良好的一致性（总肉类ICC = 0.716；各单项指标最小值 - 最大值为0.531 - 0.680）。参与者报告称该问卷易于使用，平均完成时间不到2分钟。这种新的MFQ为测量英国人群个体肉类摄入量的变化提供了一种快速、可接受且可靠的方法。
