在1996年至1998年期间，在女性健康饮食和生活研究中招募的女性的系统配额子样本（n = 397）中评估了饮食变化的测量，这是一项在乳腺癌幸存者中进行的多中心随机饮食干预试验。干预组和对照组的妇女在基线（随机化前）和第1年（随机化后）完成亚利桑那州食物频率问卷（AFFQ）和24小时饮食回忆。两种饮食测量方法均显示，干预组受试者第1年关键干预相关营养素摄入量发生显著变化，而对照组受试者变化极小或无变化。在对照组中测量了AFFQ和回忆的可靠性，并分别显示出0.63和0.43的相关性。两种工具都捕获了与饮食干预相关的饮食摄入差异。这些结果表明，使用多模式，多方法的方法（AFFQ和24小时饮食回忆）来衡量自我报告的饮食摄入量随时间的差异，如在乳腺癌幸存者中进行的饮食干预试验所示。
Measurement of dietary change was assessed in a systematic quota subsample (n = 397) of women recruited into the Women's Healthy Eating and Living Study between 1996 and 1998, a multicenter, randomized dietary intervention trial among breast cancer survivors. Women from the intervention and comparison arms completed the Arizona Food Frequency Questionnaire (AFFQ) and 24-hour dietary recalls at baseline (prerandomization) and at year 1 (postrandomization). Both dietary measurement methods demonstrated significant changes in intake of key intervention-associated nutrients at year 1 in the intervention group subjects compared with minimal or no change in the comparison group subjects. The reliability of the AFFQ and recalls was measured in the comparison group and showed correlations of 0.63 and 0.43, respectively, Both instruments captured differences in dietary intake associated with the diet intervention. These results demonstrate the utility of using a multimode, multimethod approach (AFFQ and 24-hour dietary recalls) to measure differences in self-reported dietary intake over time as shown in this dietary intervention trial being conducted among breast cancer survivors.
