Mobile health, Nutrition literacy, Ninth-grade studentsAbstract
A quasi-experimental with a two-group pretest posttest design aimed to evaluate the effectiveness of mobile health communication programin improving nutrition literacyamong Grade 9 students under the Secondary Educational Service Area Office in Nakhon Pathom Province. The sample consisted of 47 students, with 24 assigned to the experimental group and 23 to the comparison group. The experimental group received health communication content via the LINE application, based on a nutrition literacy framework, while the comparison group participated in regular health education classes. The intervention lasted 10 weeks. Data on activity acceptance and nutrition literacy were collected using self-administered questionnaires and analyzed using descriptive statistics, Chi-square test, Paired sample t-test, Independent t-test, and qualitative content analysis. Statistical significance was set at p-value < 0.05.
The results showed that the majority of students in the experimental group rated the activity acceptance as high (70.8%). All aspects-interest, content, perceived benefits, and appropriatenessreceived high mean scores (Mean = 4.33-4.56). After the intervention, the experimental group showed a statistically significant increase in mean nutrition literacy scores compared to their pretest scores (p < 0.001), and also scored significantly higher than the comparison group post-intervention (p-value < 0.001). The results indicate that health education teachers can incorporate themobile health communication programto enhance nutrition-related school health education. However, mobile health communication programs need to be strengthened, and further research on its effectiveness is recommended
