为微型计算机开发了一份自我管理的饮食评估问卷，以识别饮食模式可能使其处于癌症风险中的个体。在纽约学区的50名成年志愿者中进行了测试。问卷的定量食物频率部分（FFQ），间隔一个月进行两次，对于卡路里、脂肪、脂肪中卡路里的百分比、胆固醇、维生素A、维生素C、钙和膳食纤维是可重复的（斯皮尔曼r = 0.56-0.87）。为了检验相对有效性，将每次FFQ给药计算的个体营养素摄入量与第二次FFQ给药后一个月收集的7天食物记录计算的营养素摄入量进行比较。第一次和第二次FFQ的营养摄入量与食物记录的营养摄入量相比，脂肪千卡百分比的斯皮尔曼相关系数分别为0.58和0.62。在FFQ 1和FFQ 2之间或FFQ和食物记录之间，从脂肪中摄入的热量百分比的平均值没有显着差异。然而，平均食物记录和FFQ估计的千卡，脂肪，维生素A，维生素C，钙和膳食纤维之间有显着差异。我们的结论是，计算机化的营养评估，利用主题的数据输入，可能是适合一些临床和教育用途和研究的脂肪摄入量作为一个健康的成年人的卡路里的百分比。
A self‐administered dietary assessment questionnaire was developed for the microcomputer to identify individuals whose dietary patterns may put them at risk for cancer. It was tested among 50 adult volunteers in a New York school district. The quantitative food frequency portion of the questionnaire (FFQ), administered twice one month apart, was reproducible for calories, fat, percentage of calories from fat, cholesterol, vitamin A, vitamin C, calcium, and dietary fiber (Spearman r = 0.56–0.87). To test for relative validity, individual nutrient intake calculated from each administration of the FFQ was compared with the nutrient intake calculated from seven‐day food records collected one month after the second FFQ administration. Nutrient intake from the first and second FFQ compared with food record nutrient intake yielded a Spearman's correlation coefficient of 0.58 and 0.62, respectively, for percentage of kilocalories from fat. No significant difference in mean intake of percentage of calories from fat was found between the FFQ 1 and FFQ 2 or between the FFQs and the food record. However, there were significant differences between mean food record and FFQ estimates of kilocalories, fat, vitamin A, vitamin C, calcium, and dietary fiber. We concluded that computerized nutrient assessment, which utilizes the subject in data entry, may be suitable for some clinical and educational uses and research studies of intake of fat as a percentage of calories among healthy adults.
