Treatment Adherence and its Association with Demographic Characteristics and Clinical Factors Among Patients with Hypertension: A Cross-Sectional, Descriptive-Correlational Study

Year: 2026

Type: article

Abstract: Purpose: A blood pressure of 140/90 and above indicates high blood pressure. High blood pressure, a silent killer, is a major public health problem. Research has shown that treatment adherence plays an important role in controlling hypertension. Therefore, this study aimed to determine the level of treatment adherence among patients with high blood pressure in the health center of Semnan, 2024. Methods: In this cross-sectional study, 400 patients with high blood pressure in the health center of Semnan were selected using a multistage sampling method and enrolled after meeting the inclusion and exclusion criteria. After obtaining informed consent, demographic information and treatment adherence questionnaires were completed. Results: Of the patients, 54.3% were female. The mean ± standard deviation of age was 48.2 ± 18.2 years, with a median of 49 years. The mean ± standard deviation of the treatment adherence score was 83.8 ± 12.4 (out of 115), with a median of 89.6. Overall, 77.5% (95%CI: 73.4%-81.6%) of the patients were adherent to treatment (score ≥86). Treatment adherence was not significantly associated with age, gender, body mass index, marital status, educational level, employment status, number of children, income level, medical history, blood pressure, medication-related variables, duration of hypertension, duration of antihypertensive treatment, or other comorbidities (p > 0.05). Conclusion: Most patients had high treatment adherence, and no demographic characteristics were significantly associated with treatment adherence. Evidence indicates that knowledge influences patients' health behaviors. Therefore, policymakers and healthcare planners should prioritize educating patients with hypertension about the importance of lifestyle modification for the prevention, management, and control of hypertension. The study has several limitations, including reliance on self-reported data, its cross-sectional design, and limited generalizability of the findings.
