Prevalência de hipertensão e adesão a medicamentos de controle pressórico em adultos e idosos

Abstract

Systemic arterial hypertension is the most prevalent non-communicable chronic disease in the Brazilian population, and because it is a disease with a slow evolution and often asymptomatic for a long period, it experiences low drug adherence from patients. Objective: To describe and characterize the prevalence of drug non-adherence to antihypertensive therapy among users of primary health care (PHC) of the Unified Health System (SUS). Methods: Cross-sectional study with 447 self-reported hypertensive patients over 18 years of age, using antihypertensive drugs, users of PHC in the urban network of Passo Fundo (RS), through the application of a questionnaire. Adherence or non-adherence was defined using the Morisky Test. Those whose score was less than 6, out of a total of 8 points, were considered non-adherent. Pearson's chi square test was used for data crossings. Results: The prevalence of medication non adherence found was 31.5% (95% CI 27-36%). The profile of individuals with low adherence to antihypertensive drug therapy are adults under 60 years old (40.2%), with monthly family income less than 1 minimum wage (35.1%), overweight people ( 33.5%), smokers (42.0%), with negative self-perceived health (34.5%) and with self reported medical diagnosis of depression (40.2%). Conclusion: With these data, it is possible to outline health strategies aimed at the mentioned population in order to increase their medication adherence, and thereby, reduce the severity of decompensated disease.
