This study was conducted to investigate effects of a horticultural activity program based on a mediating variable model for improving vegetable preference among elementary students. A quasi-experimental design was employed with 136 students and 136 primary carers in Seoul, South Korea. Based on the mediation model for improving children's vegetable preference, 12 sessions were conducted, including gardening, nutrition education, and cooking activities using harvests. The program was conducted weekly for 12 weeks from March to July 2019. To investigate the effect of this program, mediating factors of the children were evaluated before and after the program. Pearson correlation analysis was used to identify the mediating factors. The nutrition index, attitude, knowledge, and eating habits of the primary carers were evaluated. Results showed children's nutrition and gardening knowledge, dietary self-efficacy, outcome expectancies, and vegetable preference were significantly improved ( < 0.001). Primary carers showed significant improvement in the nutrition index, knowledge, and attitude ( < 0.05). The correlation analysis confirmed that most of the mediating factors had significant correlations ( < 0.05). Therefore, administering a structured program involving horticultural activities and nutrition education as mediating factors for 12 sessions was effective in improving eating behavior for vegetables elementary school students and primary carers.
本研究旨在探讨基于中介变量模型的园艺活动方案对提高小学生蔬菜偏好的影响。在韩国首尔，采用准实验设计，共有 136 名学生和 136 名主要照顾者参与。基于改善儿童蔬菜偏好的中介模型，开展了 12 次园艺、营养教育和使用收获物烹饪活动。该方案于 2019 年 3 月至 7 月每周进行一次，共 12 周。为了调查该方案的效果，在方案前后评估了儿童的中介因素。采用皮尔逊相关分析来确定中介因素。评估了主要照顾者的营养指数、态度、知识和饮食习惯。结果表明，儿童的营养和园艺知识、饮食自我效能感、结果预期和蔬菜偏好显著提高（<0.001）。主要照顾者的营养指数、知识和态度也显著改善（<0.05）。相关性分析证实，大多数中介因素之间存在显著相关性（<0.05）。因此，实施包括园艺活动和营养教育在内的 12 次结构化方案作为中介因素，有效改善了小学生和主要照顾者的蔬菜食用行为。
