Urban environments in many cities, both those found in Mexico and many other countries, can be called obesogenic – they are prone to promote obesity. Relevant factors are that they foster sedentary behaviour, poor dietary choices, and elevated stress levels; thus contributing to higher obesity rates. Urban planning, design, and practices offer opportunities for upstream public health interventions to mitigate these negative health impacts. These findings are especially relevant given the role of neighbourhood environments in encouraging children’s physical activity and reducing obesity.
