Abstract
Objective: To analyze in scientific literature the risk factors for low adherence to the pharmacological treatment of systemic arterial hypertension (SAH) in patients treated at primary health care centers (PHC). Methods: This is an integrative literature review of descriptive character, carried out through the search for scientific articles indexed in the PubMed, BVS and SciELO portals. Results: The database search resulted in the selection of 18 articles, in accordance to the established inclusion and exclusion criteria. It was found that the main risk factors for low medication adherence are those of social, clinical and psychological nature, while also standing out elements related to the health services. Final considerations: Low adherence to the pharmacological treatment of SAH can be favored by a wide variety and heterogeneity of elements, which negatively impacts the control of the disease in the context of PHC. The identified risk factors are relevant for the preparation of further studies that enable the planning and execution of effective actions.
