Excessive weight gain in childhood is a growing problem. Its repercussions extend negatively to the growth and development of individuals, and it is also a risk factor for chronic non-communicable diseases in adult life. In view of the influences of home and community environments on people's lifestyle and how the urbanization process can generate obesogenic environments, it is necessary to know the influence of these spaces on the nutritional status of children. In the first part of this dissertation, a literature review was carried out contextualizing the relationship between overweight in children and the built environments resultant from the processes of urbanization of cities and changes in food systems. Then, as a result of an original epidemiological investigation, a scientific article was prepared that sought to analyze whether the prevalence of overweight in infants, preschoolers and schoolchildren has a spatial relationship with the family environment (microenvironment), community environment (mesoenvironment) and development of cities (macroenvironment). The results showed a high prevalence of overweight in preschoolers and schoolchildren, as well as its agglomeration on the Northeast coast and in the Southeast and South regions. Significant and positive spatial relationships were also found between childhood overweight and obesity in women for all stages of childhood. The development of cities was directly correlated with overweight in schoolchildren, indicating that the city does not protect children's health. In this way, we emphasize that all environments frequented by children must be promoters of healthy living habits, whether the family environment or the built environment, enabling adequate growth and development.
