[Competing ideas on the State's roles in the prevention and control of childhood obesity in Brazil].

The study analyzed competing ideas on the State's roles in the prevention and control of childhood obesity in Brazil, with cognitive analysis of public policies as the frame of reference. The study included document analysis and semi-structured interviews with 20 individuals from government, organized civil society, and the commercial private sector. The State was viewed as the main party responsible for dealing with childhood obesity, but the definitions of its roles varied according to the narratives on the factors that condition obesity and the proposed solutions. Members of the commercial private sector criticized the regulatory State in the name of parents' freedom of choice. Civil society representatives and part of the government defended regulatory measures, which they considered essential. They contended that agreements between government and the food industry to reduce unhealthy ingredients are ineffective. However, some government representatives defended such agreements. These tensions and contradictions were also expressed in the policy documents acknowledging that practices by the commercial private sector favor obesity, even while considering the private sector a partner in this process. The arguments against the regulatory State were based on individual factors conditioning obesity, but the object of regulation is institutional practices by the commercial private sector, not individual behaviors. However, this kind of argument is part of corporate policy activity, since it overlooks the conflicts of interests that have contributed to delaying the reduction in obesity prevalence.
