CONCLUSION
The global analysis of health beliefs among black people with arterial hypertension about barriers and benefits related to the diet to control the disease showed that beliefs on benefits predominated. As for socio-demographic factors associated with health beliefs on benefits of diet control, the study revealed a trend towards the perception of less beliefs on the benefits of diet in poorer socioeconomic groups, young adults, men and people without a partner, contributing to the identifying of risk groups and treatment adherence indicators. The study appointed the need to reflect on health care that acknowledges subjectivity and socioeconomic conditions as factors that can strongly influence arterial hypertension treatment adherence. Thus, promoting the health and well-being of the black population requires an interdisciplinary approach and a health policy that address their particularities and needs and are oriented towards preventive and curative aspects.
