Non-Communicable Diseases and Sanitary Injustice: The Silent Progression of NCDs in Brazil's Urban Peripheries

Non-communicable diseases (NCDs) represent one of the leading causes of illness and mortality in Brazil, with an even more significant impact in urban peripheral areas. Characterized by their long duration and the need for continuous care, these diseases are deeply associated with the social determinants of health, including factors such as income, territory, access to public services, and living conditions. This study, through a narrative literature review, analyzed how structural inequalities, weaknesses in the health system, and political neglect contribute to the advancement of NCDs among peripheral populations. The findings were organized into three thematic categories: the social and territorial determinants of NCDs, barriers to continuous care, and sanitary injustice as an expression of political invisibility. The study concludes that addressing NCDs in urban peripheries requires intersectoral action, strengthening of primary care, and political commitment to equity and social justice.
