Financial constraints and incentives for the prevention and control of obesity in the state of Rio de Janeiro, Brazil.

The present study aimed to analyze how these changes, both at the national and state levels, could affect the conditions of the implementation of obesity prevention and control (OCP) actions in primary health care (PHC) in the Rio de Janeiro State from 2014 to 2021. This study was based on policy analysis methods that emphasize the understanding of the implementation contexts, as well as the induction mechanisms and government incentives for the development of actions and integration of two projects that analyzed the OPC actions in PHC in the 92 municipalities of RJS between 2014 and 2018 (PPSUS-RJS) and between 2019 and 2021 (PEO-RJS). The results indicate that, by 2016, it was possible to observe the positive impacts of the structuring of PHC and the federal induction mechanisms in RJS. However, inflections in the expansion and funding of PHC contributed to the weakening of units, teams, and strategies, and led to retraction of resources for both state and municipal actions. Between 2016-2018, RJS's political and financial scenario deteriorated due to national crises, and the positive counterpoints since then were the induction mechanisms and federal resources that remained, in addition to the technical areas of the RJS-HD and state co-financing resources.
