          Objective To understand the effects of different health education on dietary behavior of high school students, and to provide support for appropriate and healthy dietary education.

          Methods Five high schools were selected in Gulou District, Nanjing. Two classes were randomly selected from each high school for health education intervention. Questionnaire survey was conducted before and after intervention to compare the changes in dietary behaviors.

          Results After intervention, the dietary knowledge score for the control group was (9.79±2.28), and (14.66±2.71) for the intervention group, which was statistically significant (P< 0.01). For adolescents in the intervention group, no significant differences were found before and after intervention. However, significant differences in dietary knowledge score were found for the control group before and after intervention ( P<0.01). Dietary behavior score in the intervention group before intervention was (3.34±1.78) and increased significantly after intervention (5.05 土 1.79, P<0.01). There was no statistical significance before and after intervention in the control group ( P>0.05). After the intervention, dietary knowledge scores increased significantly in the education group, mobile APP intervention group, the lecture-based study group, and the classroom-based study work group after intervention (t = -10.196, –29.222, –5.721, –14.394, P<0.01). Multivariate logistic regression analysis showed that mobile APP intervention group ( OR = 2.91), dietary knowledge score 為13 ( OR =4.43), age 為17 years ( OR = 3.72), classroom-based study group ( OR = 2.35) were positively associated with dietary behavior among high school students.

          Conclusion One-week intervention can effectively improve dietary knowledge and dietary behavior among high school students. Social media intervention shows promising effect on dietary behavior among high school students.
