Introduction: Many studies have been conducted on non-adherence with the antihypertensive treatment regime in various countries, considering the burden of cardiovascular disease (CVD) on the public health system, it is essential to carry out studies in this regard. Methods: Patients with hypertension evaluated at the family medicine clinic of Tabriz University of Medical Sciences were enrolled using simple sampling. Data gathering tool was a questionnaire consisting of three sections including the Hill-Bone compliance questionnaire, the disease characteristics, and patients’ socioeconomic. Results: Of 254 patients with hypertension, gender, income satisfaction, the occupation and the level of education did not correlate with the acceptance of the treatment. However, the number of antihypertensive medications had a significant effect on adherence with dietary orders and appointment keeping (P<0.01 and P=0.01, respectively). The number of antihypertensive drugs could statistically significantly predict overall score obtained from the questionnaire, F (1, 251) = 22.29, P<0.018. Conclusion: Factors related to the history of the disease and socioeconomic status had no effect patients adherence with treatment; however, the number of the prescribed antihypertensive drugs is in association with higher overall scores obtained through the Hill-Bone questionnaire.
