这项研究利用了先前在纽约西部饮食研究（一项针对不同地点的饮食和癌症的病例对照研究）中收集的食物使用频率数据，制定了饮食模式的衡量标准，以供随后在流行病学研究中使用。对 1475 名男性和 780 名女性对照受试者的 110 种食物的使用频率数据进行了因子分析。为每个性别提取了九个饮食模式因素。相关分析检查了癌症流行病学家关注的营养素（能量、总脂肪、膳食纤维以及维生素 A 和 C）摄入量与摄入量的关系。研究结果表明，评估饮食风险的常用指标（营养素摄入量的分位数）反映了多种饮食模式，其癌症风险因素的构成有所不同。此外，模式可能与年龄、种族和收入等变量有关，这些变量本身与癌症有关。这种方法可以为流行病学研究提供膳食暴露的综合测量。
This study used the frequency of food-use data collected previously in the Western New York Diet Study, a case-control study of diet and cancer at various sites, to develop measures of dietary patterns for subsequent use in epidemiologic research. Factor analysis was applied to frequency-of-use data of 110 foods for 1475 male and 780 female control subjects. Nine dietary-pattern factors were extracted for each gender. Correlational analyses examined relationships with intakes of nutrients of concern to cancer epidemiologists-energy, total fat, dietary fiber, and vitamins A and C. Findings indicate that the usual measure for assessing dietary risks, quantile of nutrient intake, reflects several dietary patterns differing in their composition of cancer risk factors. Furthermore, patterns may relate to such variables as age, ethnicity, and income, which are themselves related to cancer. This approach may provide a comprehensive measure of dietary exposure for epidemiologic research.
