背景针对个人特点的营养教育可能比一般的营养教育更有效。如今，计算机的使用使得更大的群体可以获得个性化的反馈。在一家大型石油公司的347名员工中进行了一项随机试验，测试了定制营养信息对脂肪，蔬菜和水果消费变化的影响。实验组的受访者收到了计算机生成的反馈信，这些反馈信针对他们的个人饮食行为、态度、感知的社会影响、自我效能期望和意识水平。对照组接受一般营养信息。实验组的受访者减少他们的脂肪消耗量显着超过对照组之间的基线和后测。裁缝的一个显着的效果也被发现的态度和意图的变化，减少脂肪摄入量和增加水果和蔬菜的消费。此外，实验组的受访者对他们收到的营养信息更满意，并且更经常地报告由于这些信息而改变他们的饮食或意图。它的结论是，计算机量身定制的营养信息是一个很有前途的手段，刺激人们改变他们的饮食对饮食建议。(C)出版社：Academic Press，Inc.
Background. Nutrition education tailored to individual characteristics of people might be more effective than general nutrition education. Nowadays, the use of computers makes individualized feedback available for larger groups.Methods. The impact of tailored nutrition information on changes in fat, vegetable, and fruit consumption was tested in a randomized trial among 347 employees of a major oil company. Respondents in the experimental group received computer-generated feedback letters tailored to their personal dietary behavior, attitudes, perceived social influences, self-efficacy expectations, and awareness levels. Respondents in the control group received general nutrition information.Results. Respondents in the experimental group decreased their fat consumption significantly more than the control group between baseline and posttest. A significant effect of tailoring was also found for changes in attitudes and intentions toward reducing fat intake and increasing fruit and vegetable consumption. Furthermore, respondents in the experimental group were more satisfied with the nutrition information they received and more often reported changing their diet or intention as a result of the information.Conclusions. It is concluded that computer-tailored nutrition information is a promising means of stimulating people to change their diet toward dietary recommendations. (C) 1996 Academic Press, Inc.
