This paper explores the ways in which the national structure of a health system influences the implementation of activities for prevention and promotion through a comparison of the experiences in four local health systems in each of Brazil and Chile. These experiences in Brazil and Chile are presented by key themes of national health system structure, local health system structure, partnership and intersectorality, human resources and introducing a family health approach. Five clear factors emerge as operating at the national level that influence prevention and promotion activities in local health systems.
