Abstract
Objective: To analyze the associated factors with adherence to pharmacotherapy in hypertension users, as well as its relationship with blood pressure control. Methods: This was a cross-sectional study, conducted with a quantitative approach and based on data collected from the RedeNut study, conducted in the Family Health Strategy of the cities heading the health regions of Pernambuco, in 2015-16. A total of 404 users over 20 years old were selected. The adherence score was based on a validated instrument, the Brief Medication Questionnaire. Results: The analyzed sample was 339 hypertensive subjects, 68,4% of women; 48.8% had their blood pressure controlled and 45.4% were also diabetic. Sixty percent were considered adherent to pharmacological treatment. In multivariate analysis, variables significantly associated with adherence were, positively, age (OR=1.028; p=0.021) and monthly family income (OR=2.147; p=0.060), and, negatively, polytherapy for diabetes (OR=0.270; p=0.010) and difficulty in taking many medicines (OR=0.357; p=0.038). Conclusion: The results showed that socioeconomic and demographic factors, as well as related to pharmacotherapy and some users' limitations, influenced adherence to pharmacological treatment. Thus, it is recommended to adopt strategies to improving adherence.
