Effects of Interactive Health Education via Line Application on Blood Pressure Level in High Normal Blood Pressure Group.

Abstract

Abstract

Hypertension is a significant public health issue in Thailand. Screening at-risk groups for hypertension and providing education to promote health behavior changes can help reduce the incidence of the disease. Currently, communication via the LINE application is widely popular. Therefore, the researcher developed an educational program through LINE to assist individuals at risk of hypertension. To compare the blood pressure levels of individuals with high normal blood pressure group between the group receiving standard education and the group receiving education combined with interaction through the LINE application. A quasi-experimental study was conducted with 50 individuals with high normal blood pressure group. The sample was randomly assigned using blocked randomization into two groups: the experimental group (25 individuals) received education along with interaction through LINE, while the control group (25 individuals) received standard education. The intervention lasted 8 weeks. Post-intervention outcomes were assessed by measuring systolic blood pressure (SBP) and diastolic blood pressure (DBP). Statistical analysis was performed using Independent T-Test, Chi-Square test, and Independent samples Mann-Whitney U test for data with non-normal distribution, with a significance level of p-value < 0.05. Data before and after the intervention within the same group were analyzed using the Wilcoxon signed-rank test with a p-value < 0.05. After the 8-week intervention, the experimental group showed a statistically significant reduction in both SBP and DBP (p<0.05). In contrast, the control group showed no significant change in SBP and DBP (p>0.05). When comparing the two groups, the experimental group showed a significant reduction in both SBP and DBP (p<0.05). Providing education combined with interaction through the LINE application can effectively reduce systolic and diastolic blood pressure in individuals with high normal blood pressure group. Further studies should follow up on blood pressure levels of the sample group at 3, 6, and 12 months after the intervention.
