We aim to evaluate the level of adherence to antihypertensive medications among patients and to assess the effect of different sociodemographic factors on the level of adherence using the Hill-Bone scale for indirect assessment.Methodology: In this cross-sectional study, we utilized a validated, face-to-face interview questionnaire to collect data on sociodemographic characteristics, participants’ attitudes, and disease knowledge. The Hill-Bone questionnaire was employed to assess treatment adherence. The statistical analysis was conducted using SPSS version 28.0, where mean, standard deviation, and range were utilized for variability analysis.Results: A total of 390 patients were included in this study. The sample comprised 56.9% of females and 56.4% of participants aged 60 years or older. Approximately 80% of participants were currently married, and 46.7% had a higher education level. The average Hill-Bone CHBPTS score was 21.23± 4.95 and indicated good adherence in 63.8% of participants. The findings showed that several factors were significantly associated with higher adherence rates, including older age (COR = 3.41, 95% CI = 1.10– 10.54, p = 0.03), higher educational level (COR = 1.72, 95% CI = 1.05– 2.83, p = 0.03), regular blood pressure monitoring (COR = 1.90, 95% CI = 1.10– 3.30, p = 0.03), and knowledge about their medications (COR = 2.12, 95% CI = 1.14– 3.94, p = 0.02).Conclusion: The medication adherence within our population falls below the desired level. Enhanced counselling and further research are necessary to identify additional factors influencing adherence and develop effective strategies for promoting adherence to antihypertensive medications.Keywords: elderly patients, hypertension, hill-bone scale, medication adherence, socioeconomic factors
