The scope of this article is to compare the effect of three health and nutrition education strategies on adherence to the non-pharmacological treatment of systemic arterial hypertension (SAH), using anthropometric, biochemical, clinical and dietetic parameters. It is a longitudinal intervention study of the comparative and quantitative approach community test. The sample was comprised of 212 individuals diagnosed with SAH, who met the inclusion/exclusion criteria. Participants were allocated into three groups, in order to evaluate different methods of intervention, carried out on a monthly basis, for twelve months. The Kolmogorov-Smirnov, ANOVA and Kruskal-Wallis tests were performed for the analyses. Educational interventions in Group 1 and 2 provided the best results on adherence to the non-pharmacological treatment of SAH. In the comparative analysis of different groups, the reduction of glucose showed statistical significant difference, with Group 2 showing the best evolution. Group 1 and 2 had better results on adherence to non-pharmacological treatment of SAH. It is important to stress that in health service practices there is a challenge to promote health education able to intervene on the issue of adherence to the treatment of SAH.
