This study was some limitations. First, we recruited patients from health centers and no detailed information was available regarding the compatibility of their drugs with the updated guidelines. Second, this study failed to control diastolic blood pressure. It seems antihypertensive therapy fail to reduce diastolic blood pressure under 100 mmHg. Although there was a statistically significant difference in mean score of the systolic blood pressure after intervention within the intervention group compared to control group, this was not clinically important. It is important to note that our study comprised of hypertensive patients who were also overweight. The intervention primarily aimed to improve health literacy, but did not encompass all aspects of a healthy lifestyle for overweight patients. Therefore, incorporating lifestyle modifications in addition to the intervention may yield better results. Therefore, interventions based on improving health literacy should be considered as an important tool alongside lifestyle modification programs for hypertensive patients. Third, patients with unsuccessful hypertension control visited physician likely more frequently than patients with controlled hypertension as they are more relaxed and did not seek medical visits. So, the result of this study may not be generalizable to other patients. Further studies can expand upon on current work to more clarify the relationship between health literacy and other health outcomes.
