Introduction: Systemic Arterial Hypertension (SAH) in Brazil is prevalent in 23.9% of individuals aged 18 years or older. International studies indicate that adherence is prevalent in approximately 50% of patients with SAH, while in Brazil, adherence rates vary between 23% and 62.1%. The great damage to patients and the extensive public health expenditures on the treatment of their complications make the topic of paramount importance. Objective: To determine the main causes of non-adherence to drug treatment for SAH. Material and Methods: A descriptive, cross-sectional, quantitative study, developed with 396 patients with SAH, selected from primary health care (PHC) centers and from the service for hypertensive individuals in the city of Juiz de Fora: Serviço de Controle de Hipertensão, Diabetes e Obesidade (SCHDO). Data collection took place between October 2018 and January 2019, making use of the Morisky-Green Test and questions added by the researchers to enhance the interpretation of the results. Results: It was observed that 279 (70.5%) of the interviewees are non-adherent to the treatment and great part of them have been at least once careless concerning the right time to take their pills (51%). In the multivariate analysis, it is clear that race is a significant variable to influence adherence to therapy (OR = 1.683; CI 1.072-2.643; p = 0.024); the percentage of white, brown and black non-adherent individuals are 40.5%, 29.4 and 30.1%, respectively; 29.5% of respondents known to be correct in their treatment. Conclusions: The main modifiable causes that result in low adherence are related to forgetfulness and carelessness. The absence of adherence is not related to the price of the medication.
