Public policy interventions for preventing and treating obesity: scoping review

Abstract

Context Obesity is a multicausal social problem and a pandemic, and it presents a public health challenge in many countries. Hence, public health interventions have been used in an endeavour to prevent and/or control increased obesity among populations. Objective This review study aimed to provide an overview of the academic literature and to analyze the strategies involved in the main public policies focused on preventing and controlling obesity in a number of countries. Data Sources MEDLINE/PubMed, Web of Science, and LILACS databases were searched. Data Extraction Original studies were included for which the core objective was related to real-life public policy interventions for obesity. Data Analysis The studies were organized according to their characteristics, and the qualitative analysis was based on the categorization proposed by the author Poulain. The review included 41 studies and identified 15 types of interventions focused on obesity; the largest proportion of actions were developed in school and city environments and were geared toward behavioral change, supported by direct or indirect government action. It was observed that many strategies focused on environmental line through regulatory and legislative measures, and health promotion geared toward the individual was based on the dissemination of information as a means for behavioral change. A smaller focus was given to individual care and treatment, and participative actions in the community. Conclusion The design of public health strategies applicable to obesity as proposed by Poulain provides a valid model for evaluating interventions. The behavioral approach involving guidance through health education toward a healthy lifestyle prevails in public policies, indicating a movement toward accountability of individuals. However, it is necessary to deepen the debate on the social structures that determine obesity (and which limit possibilities of choice), aligned with cultural change regarding its occurrence, and to employ care strategies based on scientific evidence and which focus on the needs of the subjects.
