BACKGROUND/OBJECTIVES: Adolescence is an important period for developing the knowledge and skills for healthy eating. Past studies have found that declarative knowledge of food and nutrition alone is not sufficient to improve healthy behavior, but how adolescents make connections from factual knowledge to skill and behavior is less clear. Based on cognitive development theories, a new concept, "awareness as connection", was devised, and a questionnaire addressing the connection between food, nutrition, diabetes, and behavior was developed to assess the awareness of adolescents.
A lesson designed to connect food, nutrition, and local lifestyle was piloted with a group of 146 students aged 13-17 years in northern Taiwan.
The pre- and posttest results found that students improved regarding their awareness of the association between food, nutrition, diabetes, and lifestyles ( < 0.01). The exploratory factor analysis results revealed one factor for the pre-test but two factors for the posttest, indicating growth in the students' knowledge structure. Most of the students demonstrated significant progress in the posttest, especially on the knowledge application subscale. The results reveal that students in lower grades started low and ended low but achieved greater gains than high schoolers. High-school students had better nutritional knowledge, but junior-high-school students made substantial progress on the application of this knowledge, indicating an improvement for cognitive complexity. Students with overweight started out low and achieved fewer and uneven gains than students without overweight but scored high on particular items. Gender did not have significant impact on the overall learning, but girls showed more gains in factual knowledge.
These results suggest that awareness can be a mid-step to help link knowledge to behavior, and for some, this step may take more time.
背景/目标:青春期是培养健康饮食知识和技能的重要时期。过去的研究发现,仅靠关于食物和营养的陈述性知识不足以改善健康行为,但青少年如何将事实知识与技能及行为联系起来尚不清楚。基于认知发展理论,设计了一个新的概念“意识即联系”,并开发了一份关于食物、营养、糖尿病和行为之间联系的问卷,以评估青少年的意识。
在台湾北部对一组146名13至17岁的学生进行了一项旨在将食物、营养和当地生活方式联系起来的课程试点。
前后测结果发现,学生在食物、营养、糖尿病和生活方式之间关联的意识方面有所提高(<0.01)。探索性因素分析结果显示,前测为一个因素,而后测为两个因素,表明学生的知识结构有所发展。大多数学生在后测中表现出显著进步,尤其是在知识应用子量表上。结果显示,低年级学生起点低、终点低,但比高中生取得了更大的进步。高中生有更好的营养知识,但初中生在该知识的应用方面取得了实质性进展,表明认知复杂性有所提高。超重学生起点低,比非超重学生取得的进步更少且不均衡,但在特定项目上得分较高。性别对整体学习没有显著影响,但女孩在事实知识方面的进步更大。
这些结果表明,意识可以作为帮助将知识与行为联系起来的中间步骤,对一些人来说,这一步骤可能需要更多时间。
