最近公布的数据表明，摄入一些食物与患胃癌、肠癌和口腔癌的风险之间存在关系。这引起了对这些数据准确性的关注。为了研究这一点，在西纽约癌症流行病学研究中对158名男性进行了饮食访谈，并将其与配偶在单独访谈中对丈夫饮食史的估计进行了比较。受访者被要求估计男性食用几种食物的频率。为了进行分析，频率估计值与最近流行病学分析中使用的分类相似：每周5-7次，每周1-4次，每月1-3次和每月少于一次。一般来说，60-80%的受访者对个别食品的消费频率完全一致。超过90%的配偶和被调查者的食物频率估计在一个频率类别内。夫妻之间的激烈分歧很少见；一般来说，在不到2%的夫妻对中，只有一个成员估计最高频率类别，而另一个成员估计最低频率类别。因此，作者认为，尽管饮食史不能精确地复制，但它们可能足以揭示病例和对照组之间的明显差异。
Recently published data suggest relationships between ingestion of a number of food items and risk of cancer of the stomach, bowel and mouth. This engenders concern over the accuracy of such data. To study this, dietary interviews of 158 males in the Western New York Study of Cancer Epidemiology are compared to their spouses' estimates of the husbands' dietary histories as taken in separate interviews. Respondents were asked to estimate the frequency with which the males consumed each of several foods. For analysis, the frequency estimates were assembled into categories similar to those used in recent epidemiologic analysis: 5–7 times per week, 1–4 times per week, 1–3 times per month and less than once per month. Generally, 60–80% of respondent pairs agree exactly on the frequency of consumption for individual food items. Over 90% of spouse and respondent food frequency estimates are within one frequency category of each other. Radical disagreements between spouses are rare; generally, in less than 2% of spouse pairs does one member estimate the maximum frequency category, and the other the minimum frequency category. The authors suggest therefore that, although diet histories are not precisely replicable, they may be adequate to reveal gross differences between cases and controls.
