Atopic related skin symptoms must be controlled continually. Because it is involved with food, eating behaviors play an important role in the prevention and management of atopic dermatitis. The aim of this study was to develop and apply nutrition education program for the prevention and management of atopic dermatitis on elementary school students. After applying the nutrition education program, our research attempts to evaluate the effectiveness of such nutrition education program. This study examined the effects of a nutrition education program on atopic dermatitis-related snacking behaviors, eating attitudes, and food behaviors. Subjects were 3rd grade elementary school students in Daejeon. A 6-week nutrition education program was implemented to 97 children as the educated group and another 94 children were included in the study as the control group. A self-administered questionnaire was used to assess the effects of nutrition education program. As results, eating attitudes reached significant improvement by the nutrition education program(p<0.05). In a paired t-test, the control group did not show significant difference, but the educated group showed a significant difference. In snacking behaviors, the two groups did not show statistical difference except for some considering factors. Also, there were no significant differences of the two groups after nutrition education program, except the snacking place after the nutrition education group. However, in the educated group, the types of snacks made by mothers increased 17.5% from 40.2% to 57.7%, and in-house as snacking place increased 13.4% from 68% to 81.4%. In the results of before and after the nutrition education program, the program showed some effect on the prevention and management of atopic dermatitis. Therefore, these results showed foundation for nutritional education and various educational programs are needed afterward to increase the effect of nutrition education in the prevention and management policy related to atopic dermatitis.
