| Summary: | Objectives: To evaluate environmental obesogenic‐related factors, such as physical activity in neighborhoods and schools, nutritional behavior, and intervention programs.
Sources: Critical analysis of literature with personal point of view from infant obesity experts and political advisors for public intervention.
Data synthesis: Although obesity is a public health problem affecting several age groups, it is among children and adolescents that it plays a more important role, due to treatment complexity, high likelihood of persistence into adulthood, and association with other non‐ transmissible diseases while still in early age. Environment is a main component of the genesis and outcomes in the near future or long term. Modification of intake with high‐density food, meal skipping, and high intake of saturated fat, sugar, and salt, associated to high levels of sedentarism are main causes of obesity.
Conclusion: Intervention opportunities are related to modifications in political, environmental, and individual settings. School and physical activities in the educational environment are intertwined with nutrition intervention in continuous education. A critical review of some different scenarios in Latin American countries is presented.
