Effects of health Literacy Promotion Program on Stroke Preventive Behaviors of Risk Groups Luang Nuea Subdistrict, Ngao District, Lampang Province

Abstract

     This quasi-experimental research aimed to examine the effects of a health literacy promotion program on stroke preventive behaviors among high-risk patients in Luang Nuea Subdistrict, Ngao District, Lampang Province. The study involved 60 hypertensive patients, randomly divided into an experimental group and a control group, with 30 participants in each group. The program was developed based on the health literacy framework and implemented over 12 weeks. Data collection tools included questionnaires measuring knowledge, perception, and stroke prevention behaviors. Data were analyzed using descriptive statistics and independent t-test.
     The results showed that before the intervention, both groups had moderate levels of knowledge (experimental group M = 8.73, control group M = 8.83). After the intervention, the experimental group demonstrated a significant increase in high knowledge levels (M = 12.00, p < 0.001), while the control group remained at moderate levels (M = 9.07). Perceptions of stroke risk and severity in the experimental group (M = 4.38, 4.19) were significantly higher than the control group (M = 3.70, 3.79, p < 0.001). Health behaviors in the experimental group improved across all aspects, particularly medication adherence (M = 5.00) compared to the control group (M = 4.98). Regarding clinical outcomes, the experimental group showed a significantly greater reduction in systolic blood pressure (from 150.07 to 131.37 mmHg) compared to the control group (from 154.17 to 138.07 mmHg, p < 0.001).
