Cash transfers (CTs) are now high on the agenda of most governments in low-and middle- income countries. Within the field of health promotion, CTs constitute a healthy public policy initiative as they have the potential to address the social determinants of health and health inequalities. A systematic review was conducted to synthesise the evidence on CTs´impacts on social determinants of health and health inequalities in sub-Saharan Africa, and to identify the barriers and facilitators of effective CTs.
