Abstract
Objective:
The aim of this study was to analyze non-adherence and factors associated with drug treatment of systemic arterial hypertension (SAH) among patients followed up in the Family Health Strategy (FHS).
Method:
A cross-sectional study was carried out with 682 hypertensive patients (217 men and 465 women) monitored by the FHS in Teresina (PI), using the Morisky-Green test. Socio-demographic characteristics and lifestyle, clinical, and therapeutic factors were analyzed. In the bivariate analysis, Pearson’s chi-square test (χ2) was used for qualitative variables, and Student’s t-test was used for quantitative variables. In the multiple logistic regression analysis, all the explanatory variables whose association presented p≤0.20 were initially included, and those with p≤0.05 remained in the final model.
Results:
The prevalence of non-adherence to drug treatment for SAH was 64.5%. The highest chance of non-adherence was associated with female gender, younger age group, alcohol consumption, uncontrolled blood pressure, adverse drug reactions, and non-attendance at consultations.
Conclusions:
The high prevalence of non-adherence to drug treatment for SAH in the FHS signals the need to establish effective strategies in order to qualify care for hypertensive patients, increase treatment adherence, and reduce complications associated with SAH.
