两种饮食评估方法的有效性，即自我管理的食物频率问卷和面试者管理的详细饮食历史，在1990年5月至7月期间在加拿大多伦多对95名男性和108名女性的人群样本进行了7天的食物记录评估。每个研究对象都完成了两种问卷方法，一份食物频率问卷和一份面试者管理的饮食历史，以及交叉设计的7天食物记录。对未调整的和能量调整的营养素的数据进行了分析，以评估皮尔逊和组内的相关性和类别内的一致性。两种问卷法评估的大多数营养素摄入量的平均值是相似的。男性在食物频率问卷和7天食物记录之间的平均能量调整皮尔逊相关系数为0.55和0.48，而面试者管理的饮食历史和7天食物记录之间的宏观和微量营养素的相关系数分别为0.47和0.48。对于女性来说，在食物频率问卷和7天食物记录之间，宏观营养素和微量营养素的得分分别为0.48和0.54，在采访者管理的饮食史和7天食物记录之间，分别为0.46和0.49。能量调整后的皮尔逊相关系数普遍高于能量调整后的皮尔逊相关系数和组内相关系数。目前的研究表明，食物频率调查问卷可以与面试者管理的饮食历史相媲美，作为从7天食物记录估计的营养素的预测因子。
The validity of two types of diet assessment methods, a self-administered food frequency questionnaire and an interviewer-administered detailed diet history, was assessed relative to a 7-day food record on a population-based sample of 95 men and 108 women in Toronto, Canada, between May 1989 and July 1990. Each study subject completed both questionnaire methods, a food frequency questionnaire and an interviewer-administered diet history, as well as a 7-day food record in a crossover design. Data were analyzed for both unadjusted and energy-adjusted nutrients to estimate Pearson's and intraclass correlations and agreement within categories. Mean values for the intake of most nutrients assessed by the two questionnaire methods were similar. Average, energy-adjusted Pearson's correlation coefficients for men between a food frequency questionnaire and a 7-day food record were 0.55 for macronutrients and 0.48 for micronutrients compared with 0.47 for macro- and 0.48 for micronutrients between an interviewer-administered diet history and a 7-day food record. For women, they were 0.48 for macro-and 0.54 for micronutrients between a food frequency questionnaire and a 7-day food record and 0.46 and 0.49, respectively, between an interviewer-administered diet history and a 7-day food record. The energy-adjusted Pearson correlations were generally higher than were the energy-unadjusted Pearson correlations and the intraclass correlations. The present study suggests that a food frequency questionnaire is comparable with an interviewer-administered diet history as a predictor of nutrients as estimated from a 7-day food record.
