Key result
High medication adherence was associated with a lower likelihood of uncontrolled blood pressure (OR 0.47; 95% CI 0.24-0.93) among Omani patients with hypertension.
Why the study?
Are health beliefs and self-efficacy associated with medication adherence and blood pressure control in patients with hypertension?
Cross-Sectional (n=215)
Are health beliefs and self-efficacy associated with medication adherence and blood pressure control in patients with hypertension?
Odds Ratio: 0.47 (95% CI 0.24–0.93)
Patient beliefs and self-efficacy are significantly associated with medication adherence and blood pressure control in hypertensive patients.
Supports adherence strategies for BP control; extends cross-sectional links but leaves causal mechanisms open.
BACKGROUND: Patients' health beliefs are essential to improve medication adherence among patients with hypertension. OBJECTIVE: Our objective was to examine the relationship between (1) patients' beliefs about hypertension, medication, and self-efficacy and medication adherence and (2) medication adherence and blood pressure control in Oman. METHODS: This cross-sectional study included 215 participants with hypertension. Participants completed 4 questionnaires (Arabic version) to measure medication adherence, beliefs about hypertension severity, beliefs about medication, and self-efficacy. Bivariate and multivariate logistic regression was used to conduct the analyses. RESULTS: Higher self-efficacy (odds ratio [OR], 2.59; 95% confidence interval [CI], 1.54-4.37), stronger beliefs about medication necessity (OR, 1.98; 95% CI, 1.21-3.23), increased age (OR, 1.06; 95% CI, 1.03-1.10), and fewer medication concerns (OR, 0.34; 95% CI, 0.20-0.57) were related to high medication adherence. Moreover, uncontrolled blood pressure was less likely in participants with high medication adherence (OR, 0.47; 95% CI, 0.24-0.93). CONCLUSIONS: Patients' beliefs are important consideration to improve medication adherence. Clinically, patients' beliefs should be assessed, and strategies to improve medication adherence should incorporate beliefs as a key component to improve antihypertensive medication adherence. Patient education and counseling regarding hypertension and necessity and side effects of medications are important to maximize positive beliefs and improve medication adherence.

Al‐Noumani et al. (2018) conducted a cross-sectional in hypertension (n=215). High medication adherence vs. Lower medication adherence was evaluated on Uncontrolled blood pressure (OR 0.47, 95% CI 0.24-0.93). High medication adherence was associated with a lower likelihood of uncontrolled blood pressure (OR 0.47; 95% CI 0.24-0.93) among Omani patients with hypertension.
