The Effects of a Health Media Program to Improving Health Literacy for Stroke Prevention in Uncontrolled Hypertensive Patients in Ban Na Sub-district, Srinagarindra District, Phatthalung Province

Abstract

This study employed a one-group quasi-experimental design to examine the effects of a health media program on improving health literacy for stroke prevention among patients with uncontrolled hypertension in Ban Na Sub-district, Srinakarindra District, Phatthalung Province. The sample consisted of 32 participants, and the intervention was implemented over a period of three months. The program utilized health education videos and infographics that provided knowledge on stroke prevention, exercise, stress management, self-management skills, and decision-making for disease prevention. The media were disseminated via the LINE application. Data were collected using a structured questionnaire that was validated by experts, yielding an Item–Objective Congruence (IOC) index of 0.97 or higher for all items. Data were analyzed using descriptive statistics, including frequency, mean, and standard deviation, and inferential statistics, namely the Wilcoxon signed-rank test and the paired t-test.

After participation in the program, participants’ health literacy for stroke prevention significantly increased (P-value < 0.001). Health behaviors related to stroke prevention also improved significantly (P-value = 0.038). The risk level for stroke significantly decreased (P-value < 0.001). Moreover, systolic blood pressure significantly decreased (P-value < 0.001), and diastolic blood pressure significantly decreased (P-value = 0.008). Continuous follow-up and evaluation of health behavior modification, together with empowerment of program participants, are recommended to sustain long-term benefits.
