Abstract

Background

Given that patients’ medication adherence is regarded as the major part of disease control and improving health literacy can be effective in promoting adherence to healthy behaviors, the present study aimed to investigate the effect of health literacy intervention based on the medication adherence among uncontrolled hypertensive patients using mobile health (M-health).

Methods

An interventional study with a quasi-experimental design, was conducted on 118 uncontrolled hypertensive patients. Participants were randomly divided into the intervention (n = 59) and control (n = 59) groups using blocked randomization. In the intervention group, a mobile health (M-health) program was designed using programmed instruction to improve patients’ health literacy over a period of 3 months. Data was collected by administering health literacy and medication adherence questionnaires to participants before and after the intervention. The analysis involved using the independent sample t-test to compare the variables before and after the study.

Results

Before the intervention, the total score of health literacy was 33.34 and 33.14 in the intervention and control groups, respectively. After the intervention, it increased to 40.36 and 34.20 in the intervention and control groups, respectively, which was statistically significant in the intervention group (p = 0.01). Moreover, the medication adherence score of the intervention group significantly increased after the intervention. Both systolic and diastolic blood pressure decreased in the intervention group. However, it should be noted that the decrease in systolic blood pressure by 148.98 was statistically significant, while the decrease observed in diastolic blood pressure in the intervention group was not statistically significant (p = 0.08).

Conclusion

The application of programmed instruction through M-Health has shown a positive effect on the health literacy of uncontrolled hypertensive patients. In addition to detecting and treating patients, it is important to prioritize the improvement of health literacy in terms of medication adherence and the adoption of healthy behaviors.
