Introduction:

The therapeutic approach to high blood pressure includes non-drug and pharmacological measures. Non-adherence to treatment is one of the greatest, and consequently one of the most important challenges for public health.

Objective:

To characterize the factors associated with adherence to medication and non-medication treatment of hypertensive patients.

Methods:

This is a descriptive, quantitative and cross-sectional study conducted in a Basic Health Unit in the city of Teresina- Piauí with 160 hypertensive patients. The data were collected from February to July 2019 by applying a semi-structured questionnaire containing questions related to socioeconomic and demographic aspects, non-drug treatment, blood pressure verification and knowledge of antihypertensives in use. For the data analysis, the chi-square test with significance of 95 % was considered considering 2x2 independence tests in the combination of variables.

Results:

The sample consisted of women, elderly, retired, with wage income between one and two minimum wages. The main lifestyle modification adopted was abstention from alcohol and tobacco use. Most stated that they routinely check blood pressure (57,50 %), have knowledge about the antihypertensive medication in use (68,00 %) and are satisfied with the care established at the basic health unit (78,75 %).
