INTRODUCTION: The World Health Organization defines patient adherence as the willingness to adapt its behavior (in terms of therapy, diet, lifestyle, and diagnostic procedures) to the recommendations agreed with the healthcare provider. Objective. The study aimed to determine the impact of socio-demographic factors and length of elevated blood pressure on the adherence of patients with arterial hypertension. METHOD: The study was performed as a cross-sectional study. The sample consisted of 170 patients, 88 (51.8%) women and 82 (48.2%) men, with a mean age of 58 ± 7.9 years. In addition to the general questionnaire, the study used the Adherence in Chronic Diseases Scale. RESULTS: Statistically significantly higher adherence was found in subjects aged 60-69 years and participants in the study with arterial hypertension for more than 15 years (p<0.05). Subjects with completed primary school had statistically significantly lower adherence (p<0.05). Place of residence, employment status and gender of the respondents did not show a statistically significant influence on the adherence of the respondents (NS). CONCLUSION: It uses the age, educational status and duration of arterial hypertension in the adherence of examination statistics. Place of residence, employee status and gender of respondents do not show a statistically significant impact.
