摘要
Objective: The purpose of the present study was to investigate the impact of a school-based nutrition and media education intervention on the promotion of fruit and vegetable consumption to help prevent childhood obesity. Design: The 10-week-long intervention included sessions on nutrition education and media literacy. It also included a health communication media-based campaign workshop during which the children created posters, newsletters and video commercials related to fruits and vegetables targeted to their parents. For evaluation purposes, the study utilized a mixed-methods approach, including a quasi-experimental study (with one intervention group and one control group) and a focus group study. Setting: Four different elementary schools in Treviso (Veneto Region of Italy) agreed to participate in the research. Subjects: The target population for the study included 10-year-old Italian children and their parents. Results: Data indicate that this intervention was effective for children but not for parents. Evaluation results show that the intervention was effective in significantly increasing children's fruit and vegetable intake (P<0.05) and all psychosocial determinants (P<0.05). Conclusions: The study results confirm the efficacy of a school-based health and media education intervention to address the children's obesity issue and, in particular, to increase children's fruit and vegetable intake. The study also opens a new perspective on the theoretical constructs investigated, because the development of 'ability of expression' could be considered one of the most important factors to determine the efficacy of the intervention.
