This paper explores the role of social media in promoting self-care for Systemic Arterial Hypertension (SAH) and addressing health inequities, emphasizing its significance in the context of the COVID-19 pandemic. It calls for a focus on social determinants of health and highlights the global impact of Chronic Non-Communicable Diseases (NCDs), with a particular focus on Brazil's healthcare system. The research, a collaboration between the University of Brasília and the research initiative Escola de Pacientes DF (EP-DF), employs Participatory Community Based Research (CBPR) to evaluate the impact of social media on SAH self-care in urban areas with social inequities. The study includes a scoping review of relevant articles, document analysis of SAH patient testimonials, and knowledge translation for community understanding. Results from the scoping review show positive changes in self-care behaviors due to social media interventions, while acknowledging challenges such as low Functional Health Literacy (FHL), age, education, and internet access. In conclusion, the paper highlights social media's potential in improving healthcare accessibility and equity for SAH and NCDs in vulnerable communities.
