Conditional cash transfer programs are strategies used by countries over the past two decades, and they play a key role in reducing income inequalities and expanding access to basic services such as health and education. The Brazilian Cash Transfer Program (Bolsa Família), the largest conditional cash transfer program in the world, aims to bring immediate poverty alleviation and eradicate hunger. The objective of this study was to analyse the contributions of the Brazilian Cash Transfer Program for reducing social inequalities and ensuring the right to health, food, education and social assistance in Brazil. A review of the scientific literature published between 2003 and 2020 was conducted, associated with documentary research on government websites. There was a relationship between the Brazilian Cash Transfer Program, reduction of child mortality and increase in access to Primary Health Care services; increased access to food, including in natura; higher school attendance and reduced dropout. However, no improvement in the nutritional status of the families entitled to the program was observed, nor the interruption of the intergenerational cycle of poverty was ensured. The Brazilian Cash Transfer Program continues as a potent intersectoral policy for reducing inequities, which reinforces the need to strengthen and combine complementary policies to expand its effects.
