Effectiveness of a nutrition education intervention using simulation videos and encouragement of parental involvement for elementary school students

This study aims to develop a nutrition education intervention to promote healthy eating, and to evaluate the effectiveness of this intervention on healthy eating knowledge, attitude and behaviour among elementary students. A quasi-experimental study was conducted in two elementary schools in Taiwan. The intervention course design included simulation videos, lectures, and the after-school learning worksheet designed for parental involvement. A total of 4 courses along with 4 simulation videos were given to the intervention group. The four course themes were Sugar patrol, Balanced Diet during the Mid-Autumn Festival, Rainbow Fruit and Vegetables, and Smart Dine Out. The study recruited 35 3rd grade students for the intervention group and 30 for the control group. Data were collected from the pre- and post-test questionnaires. The nutrition intervention had significant effects on improving participants' knowledge about tips for making healthy choices and the necessity of balanced diet, and on attitude toward healthy eating. There was no significant improvement in participants' healthy eating behaviours. This nutrition education intervention, which utilized simulation videos and encouraged parental involvement, could be recommended for teaching practice in elementary schools to improve healthy eating knowledge and attitude among students.
