The aim of the present paper is to describe the essential elements of computer-tailored nutrition education and to study the impact of written computer-tailored nutrition education in comparison to general written nutrition advice.
The impact of computer-tailored nutrition education was studied in three randomised trials as compared to general nutrition education. The data of the three studies were taken together and re-analysed.
Random samples of employees at two work sites and a self-selected sample of the Dutch adult population. The total number of subjects was 1309. Response rates were between 45% in one of the work sites and 88% in the self-selected sample.
Subjects in the experimental condition received computer-tailored nutrition education. With computer-tailoring, expert individualised nutrition education can be realised through an automated process for relatively large target groups with relatively low costs per person.
The impact on changes in fat intake were studied. The use and appreciation of the intervention was also assessed.
Subjects who received computer-tailored advice had a lower mean fat score at post-test, adjusted for baseline intake levels. Subjects who received tailored advice were more likely to have read and discussed the nutrition advice.
The results point to the conclusion that printed computer-tailored nutrition education is superior to general written nutrition education.
本文旨在描述计算机定制营养教育的基本要素，并研究书面计算机定制营养教育与一般书面营养建议相比的影响。
与一般营养教育相比，在三项随机试验中研究了计算机定制营养教育的影响。将三项研究的数据汇总并重新分析。
两个工作场所员工的随机样本以及荷兰成年人口的自选样本。受试者总数为1309人。回复率在一个工作场所为45%，在自选样本中为88%。
实验条件下的受试者接受计算机定制营养教育。通过计算机定制，可以通过自动化过程为相对较大的目标群体实现专家个性化营养教育，且人均成本相对较低。
研究对脂肪摄入量变化的影响。还评估了干预措施的使用和满意度。
在根据基线摄入量水平进行调整后，接受计算机定制建议的受试者在测试后的平均脂肪得分较低。接受定制建议的受试者更有可能阅读和讨论营养建议。
结果表明，印刷的计算机定制营养教育优于一般书面营养教育。
