There is ample evidence that printed, computer-tailored nutrition education is a more effective tool for motivating people to change to healthier diets than general nutrition education. New technology is now providing more advanced ways of delivering tailored messages, e.g. via the World Wide Web (WWW). Before disseminating a tailored intervention via the web, it is important to investigate the potential of web-based tailored nutrition education. The present study investigated the immediate impact of web-based computer-tailored nutrition education on personal awareness and intentions related to intake of fat, fruit and vegetables. A randomized controlled trial, with a pre-test-post-test control group design was conducted. Significant differences in awareness and intention to change were found between the intervention and control group at post-test. The tailored intervention was appreciated better, was rated as more personally relevant, and had more subjective impact on opinion and intentions to change than the general nutrition information. Computer literacy had no effect on these ratings. The results indicate that interactive, web-based computer-tailored nutrition education can lead to changes in determinants of behavior. Future research should be aimed at longer-term (behavioral) effects and the practicability of distributing tailored interventions via the WWW.
有充分证据表明，与一般营养教育相比，印刷版的、计算机定制的营养教育是促使人们转向更健康饮食的更有效工具。新技术现在提供了更先进的方式来传递定制信息，例如通过万维网（WWW）。在通过网络传播定制干预措施之前，研究基于网络的定制营养教育的潜力很重要。本研究调查了基于网络的计算机定制营养教育对与脂肪、水果和蔬菜摄入量相关的个人意识和意图的即时影响。进行了一项随机对照试验，采用前测-后测对照组设计。在后测时，干预组和对照组在意识和改变意图方面存在显著差异。与一般营养信息相比，定制干预措施更受青睐，被认为更具个人相关性，并且对观点和改变意图有更大的主观影响。计算机素养对这些评分没有影响。结果表明，交互式的、基于网络的计算机定制营养教育可以导致行为决定因素的改变。未来的研究应针对长期（行为）影响以及通过万维网分发定制干预措施的实用性。
