有充分的证据表明，与一般的营养教育相比，印刷的、由计算机定制的营养教育是一种更有效的工具，可以激励人们转向更健康的饮食。新技术现在提供了更先进的方式来传递定制的消息，例如通过万维网(WWW)。在通过网络传播量身定做的干预措施之前，重要的是调查基于网络的量身定制营养教育的潜力。本研究调查了基于网络的量身定做的营养教育对个人摄入脂肪、水果和蔬菜的意识和意图的直接影响。采用随机对照试验，采用前测-后测的对照组设计。干预组和对照组在后测时的改变意识和改变意向上存在显著差异。与一般营养信息相比，量身定制的干预措施更受欢迎，被评为与个人更相关，对观点和改变意图的主观影响更大。计算机素养对这些评分没有影响。结果表明，互动的、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变化。未来的研究应该着眼于更长期的(行为)影响和通过WWW分发量身定制的干预措施的实用性。
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.
