在一项以人群为基础的新泽西州男性肺癌病例对照研究中，为了评估类胡萝卜素的保护潜力，在访谈中纳入了成人通常食用的许多蔬菜和水果。根据900名受控的新泽西白人男性的数据，他们主要在特定季节吃特定的蔬菜和水果，确定了应季和非应季消费的相对重要性，以及季节的中位数长度。虽然首先询问一种食品是全年消费还是主要在某些季节消费，然后询问适当的消费频率有助于访谈，但没有必要获得非季节消费频率和季节长度。用0代替报告的非季节频率，用3个月代替报告的季节长度，可以略微降低观察到的饮食和肺癌风险之间的关联，但并没有改变所注意到的总体模式。据估计，冬秋季类胡萝卜素的摄入量约为夏春季的三分之二。
In a population-based case-control study of lung cancer among New Jersey men, usual adult consumption of many vegetables and fruits was included in the interview to assess the protective potential of carotenoids. With data from 900 controls the percentage of New Jersey white men who eat specific vegetables and fruits primarily in certain seasons, the relative importance of in-season and out-of-season consumption, and the median length of season were determined. Although first asking whether a food item was consumed all-year-round or primarily in certain seasons and then asking for the appropriate frequency of consumption facilitated the interview, obtaining out-of-season frequency of consumption and length of season was not necessary. Substituting 0 for reported out-of-season frequencies and 3 mo for reported season lengths reduced slightly the observed associations between diet and lung cancer risk but did not modify the overall pattern noted. Carotenoid intake in winter-fall was estimated to be about two-thirds that in summer-spring.
