This article aims to evaluate the adherence to antihypertensive treatment prevalence in the Brazilian population based on peer-reviewed studies which used instruments exclusively designed and/or adapted for this purpose. A systematic review with meta-analysis based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search was carried out in the BDENF, SciELO, Cuiden, PsycINFOe, CINAHL, Embase, LILACS, and MEDLINE databases, as well as the AgeLine, Google Scholar and Science-Direct academic search engines. The protocol was registered with PROSPERO (CRD42021292689). Random effects models were used for a meta-analysis of the prevalence obtained from individual studies. A total of 104 studies were included in the meta-analysis on antihypertensive treatment in the Brazilian population, totaling 38,299 patients. The most used instrument was the four-item Morisky-Green Test (49.5%). The adherence prevalence estimated by the meta-analysis was 44.4% (95%CI: 39.12%-49.94%, [I.sub.2] = 91.17, p < 0.001), showing high heterogeneity. The adherence to antihypertensive treatment prevalence found in national studies was unsatisfactory, demonstrating that this problem continues to be a major challenge.
