在饮食与乳腺癌的病例对照研究中，已经开发和评估了三种估计群体和个人饮食消费的方法。这些方法包括24小时回忆，最近两个月和六个月前两个月的详细定量饮食史，以及为期四天的饮食日记。使用每种方法的对照组摄食量估计值之间存在高度相关性。最高的估计值来自饮食史，6个月前的估计值略高于当前时期，而最低的估计值来自24小时回忆。后者与加拿大营养调查中的相同方法相一致。结论：所有方法均适用于病例对照研究，但当当前食物摄入可能受疾病影响时，应首选饮食史。
Three methods of estimating group and individual dietary consumption have been developed and assessed in a case-control study of diet and breast cancer. The methods comprised a 24-hour recall, a detailed quantitative diet history directed to the most recent two-month period and the two-month period six months before, and a four-day diet diary. There is a high degree of correlation between the estimates of food consumption for the controls using each of the methods. The highest estimate was obtained from the diet history, with a slightly higher estimate in the period six months before than the current period, while the lowest is found in the 24-hour recall. The latter corresponds with the same method in a Nutrition Canada Survey. It is concluded that all methods ara applicable to case-control studies, but the diet history is preferred when current food intake may be influenced by a disease.
