Tóm tắt

Introduction: While there are numerous studies on hypertension prevention, there is limited evidence regarding the effectiveness of school-based interventions. This study aimed to evaluate the outcomes of interventions designed to improve knowledge about hypertension among high school students in a mountainous area.

Methods: A quasi-experimental study was conducted with students at Dong Hy High School in Thai Nguyen Province, involving 368 students across 10th, 11th, and 12th grades. For each grade, three classes were randomly selected for the study, in which one class from each grade was randomly assigned to the intervention group and the remaining two classes were assigned to the control group. The main variables included knowledge on the definition, risk factors, and prevention of hypertension. Health education sessions were conducted in the intervention group by the Youth Union and class leaders. Difference-indifferences analysis was applied to estimate the effectiveness.

Results: The total score at the baseline survey was 15.07 out of 29 points. The intervention by the health education sections revealed that the effectiveness of the health education intervention improved the knowledge by 0.12 points. However, this change was not statistically significant, except for the improved knowledge about daily salt intake among 24% of the students (p<0.001).

Conclusion: The intervention had an impact on changing the knowledge about daily salt intake among 24% of the high school students. To be able to enhance knowledge of hypertension among high school students, future research should consider factors such as enhancing students’ need, using better visual media, engaging intervention activities while designing interventions.
