Obesity prevalence has been rising worldwide and currently is one of the most serious public health problems. Nutrition literacy is important to the development of healthier habits that could help prevent and stem obesity and overweight. The aim of this study was to evaluate the impact of using a multimedia web platform to provide nutrition education to Portuguese adolescents.
The intervention consisted in a two-week period in which students (n = 1291) had access to an interactive multimedia web platform with nutritional content, and designed for a self-paced learning experience. Students completed a knowledge questionnaire at baseline and immediately after the end of the intervention.
The results obtained revealed that 85.8% of the students increased their nutrition knowledge. No gender differences were observed post-intervention. There were significant differences in the knowledge acquisition regarding age (P < 0.001). The baseline knowledge seemed to influence the learning process.
Overall, the intervention had a positive impact. The preliminary results observed will be important for the improvement of the intervention, though they need to be confirmed by further research. Nevertheless, it is safe to say that technology-based assets can be important tools to incorporate and complement health-related interventions in schools.
肥胖患病率在全球范围内呈上升趋势，目前是最严重的公共卫生问题之一。营养素养对于养成有助于预防和遏制肥胖及超重的更健康习惯至关重要。本研究的目的是评估使用多媒体网络平台为葡萄牙青少年提供营养教育的影响。
干预为期两周，在此期间学生（n = 1291）可以访问一个包含营养内容的交互式多媒体网络平台，该平台旨在提供自主学习体验。学生在基线时以及干预结束后立即完成一份知识问卷。
所得结果显示，85.8%的学生增加了营养知识。干预后未观察到性别差异。在年龄方面的知识获取上存在显著差异（P < 0.001）。基线知识似乎会影响学习过程。
总体而言，干预产生了积极影响。尽管观察到的初步结果需要进一步研究加以证实，但对于改进干预措施而言，这些结果将具有重要意义。然而，可以肯定地说，基于技术的资源可以成为学校纳入和补充与健康相关干预措施的重要工具。
