Abstract

Purpose
This study examined the effects of nutritional education related to sugar in elementary school children on nutritional knowledge, attitude, and dietary behavior.
Methods
A questionnaire survey on the knowledge, attitudes, and intake related to sugar was conducted on 572 students in grades 4–5, who were attending five elementary schools in Seoul and Gyeonggi-do.
Results
Among the survey subjects, 270 (49.8%) were cognitive in education, and 302 (50.2%) were non-cognitive. The sugar-related knowledge score was 3.67 points in the cognitive education group, which was significantly higher than the 3.55 points in the non-cognitive group. The rate of checking the sugar content in the nutrition label was 31.2% in the cognitive education group, which was significantly higher than in the non-cognitive group, 15.4%. The cognitive education group had a higher intake frequency of unsweetened candy, jelly, and raw fruits, and higher sugar intake of unsweetened bread, white milk, and raw fruits than the non-cognitive group. In the case of the cognitive education group, the total knowledge score showed a positive correlation with the food behavior scores, and a negative correlation with the frequency of purchasing snacks after school, and the average sugar intake per day. In the cognitive education group only, the education of nutrition teachers was analyzed as a factor to reduce the total sugar intake. The cognitive group of sugar education tried to eat foods with a lower sugar content than the non-cognitive group, and nutrition education was an important factor affecting the sugar intake.
Conclusion
To reduce the sugar intake of elementary school students, it will be necessary to practice oriented-nutrition education by nutrition teachers continuously. In addition, it is important to develop and disseminate various types of nutrition education materials related to sugar that can be utilized easily by nutrition teachers.
