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

Most hypertensive patients in the Semnan health center sample were classified as adherent to treatment.

• Overall, 77.5% (95%CI: 73.4%-81.6%) of the patients were adherent to treatment, defined as a score ≥86.
• The sample comprised 400 patients with high blood pressure selected by multistage sampling.
• Data were collected in 2024 using demographic information and treatment adherence questionnaires after informed consent.

The mean treatment adherence score was 83.8 out of 115.

• Mean ± SD adherence score was 83.8 ± 12.4 (out of 115).
• The median score was 89.6, higher than the mean, indicating a left-skewed distribution.
• The adherence cut-off was a score of 86 or above.

Treatment adherence was not significantly associated with any of the demographic characteristics examined.

• Non-significant (p > 0.05) variables included age, gender, body mass index, marital status, educational level, employment status, number of children, and income level.
• Participants had a mean ± SD age of 48.2 ± 18.2 years (median 49), and 54.3% were female.

Treatment adherence was not significantly associated with clinical or medication-related factors.

• Non-significant (p > 0.05) variables included medical history, blood pressure, medication-related variables, duration of hypertension, duration of antihypertensive treatment, and other comorbidities.

The authors conclude that patient education about lifestyle modification should be prioritized by policymakers and healthcare planners.

• They cite evidence that knowledge influences patients' health behaviors.
• Education is proposed for the prevention, management, and control of hypertension.

The study has several acknowledged limitations.

• Reliance on self-reported data.
• Cross-sectional design, which limits causal inference.
• Limited generalizability of the findings.
