In Peru, obesity was modeled among boys and girls under 5 years of age. The scenario considered variables related to housing conditions, education, and social vulnerability: inadequate housing, difficulties relating to or communicating with others, mobility difficulties, households with children who do not attend school, illiteracy, and households with dirt floors or other non-consolidated materials.

These variables were prioritized because they reflect structural conditions of the household and the social environment that may be related to inequalities in children’s health and nutrition. The spreadsheet notes that environmental variables had greater predictive weight, but they were more complex to modify in a realistic scenario; therefore, changes in social and housing-related variables were chosen. The final effect was limited: average obesity decreased from 1.71% to 1.68%.
