The effect of health promotion program on blood pressure control behavior of hypertensive patients at Bankhaolaem Health Promoting Hospital Photharam District, Ratchaburi Province

Abstract

This research is a two-group quasi-experimental study with pre-test post-test design. To study the effect of a health promotion program on blood pressure control behavior in hypertensive patients. The sample consists of hypertensive patients attending the chronic disease clinic at Ban Khao Laem Sub-district Health Promoting Hospital, Ratchaburi Province. They are divided into an experimental group and a control group, each with 30 participants. Data collection will take place between June and August 2025. The experimental group will receive a health promotion program to modify blood pressure control behaviors for 12 weeks, while the control group will receive standard nursing care. Data collection tools include a blood pressure control behavior questionnaire and a blood pressure assessment form completed by five experts, with an Index of Item Objective Congruence value of .67-1.00. Cronbach’s Alpha coefficient is .84. Data will be analyzed using descriptive statistics, chi-square test, t-tests, and repeated measure ANOVA.

The results showed that after participating in the experimental group they had significantly better blood pressure control behaviors than before the program (p = .007) and significantly lower blood pressure values than before the program (p < .001). Before the program, there were no statistically significant differences in blood pressure control behaviors and average blood pressure values between the experimental and control groups (p = .104, p = .339). After the program, the experimental group had significantly higher average blood pressure control scores and lower blood pressure values than the control group (p < .001).
