Insights
Patient adherence to hypertension treatment is poor, impacting health outcomes. Strategies like patient education and fixed-dose combination therapies are crucial for improving medication adherence and managing high blood pressure.
Area of Science:
- Cardiology
- Public Health
- Pharmacology
Background:
- Hypertension is a significant global health concern.
- Effective management relies on lifestyle changes and medication.
- Suboptimal patient adherence hinders treatment success due to various factors.
Purpose of the Study:
- To evaluate adherence to lifestyle modifications and pharmacotherapy in hypertensive patients.
- To identify factors associated with non-adherence to hypertension management.
Main Methods:
- A cross-sectional study involving 200 hypertensive patients.
- Assessed lifestyle adherence via questionnaires, including salt intake, DASH diet, and physical activity.
- Utilized the Morisky Medication Adherence Scale (MMAS-4) for medication adherence assessment.
Main Results:
- Overall adherence to lifestyle modifications was 39.8%.
- Medication adherence was poor in 58.3% of patients.
- Poor medication adherence linked to older age, lower socioeconomic status, and free-dose combination therapy.
Conclusions:
- Suboptimal adherence significantly compromises hypertension control.
- Patient education and fixed-dose combination therapies show potential for improving outcomes.
- Further multicenter research is needed due to population and healthcare context variability.
Introduction:
Hypertension represents a major public health challenge, contributing to the global health burden. Lifestyle modifications and pharmacotherapeutic interventions are the cornerstones in the management of hypertension. However, suboptimal adherence remains a critical impediment to achieving desired clinical outcomes, stemming from a complex interplay of socioeconomic factors, access to care, and affordability of medications. Therefore, the objective of this study was to assess adherence to lifestyle modifications and drug therapy and their associated factors.
Methods:
A monocentric cross-sectional study was conducted on 200 hypertensive patients from July 1st to October 30, 2022. Participants were selected using a consecutive sampling technique. Adherence to lifestyle modifications was assessed through questions filled in a data sheet, with consumption of salt and the DASH diet evaluated using a Food Frequency Questionnaire and the Hill-Bone Compliance to High Blood Pressure Therapy Scale, while medication adherence was assessed using the Morisky Medication Adherence Scale with 4 items (MMAS-4).
Results:
The overall adherence to lifestyle modifications was 39.8%, with good adherence to fruit and vegetable consumption at 59.5%, adherence to a low-salt diet at 43%, and physical activity at 24.5%. According to the MMAS-4, poor medication adherence was observed in 58.3% of our patients and was associated with advanced age (>60 years; p = 0.014), low socio-economic level (p = 0.012), and use of free-dose combination therapy (p = 0.001).
Discussion:
Our study demonstrates that poor adherence critically undermines hypertension control, while patient education and fixed-dose combination therapies improve outcomes. However, variability across populations and healthcare contexts limits generalizability and warrants further multicenter research.
Conclusion:
The findings of this study indicate that therapeutic adherence among individuals with hypertension remains suboptimal, highlighting the need for a comprehensive, multifactorial strategy to address the diverse and intersecting determinants of nonadherence.
