A study from the Barcelona Institute for Global Health (ISGlobal) "suggests that the built environment, green space and air pollution can affect cognitive and motor function in children." The study analyzed 13 risk factors that can impact cognitive development, including "the built environment (building density, proximity to public transport, facility richness, etc.), natural spaces, and air pollution from nitrogen dioxide (NO2) and fine particulate matter (PM2.5)." Results showed a correlation between urban design and children's cognitive and motor function.

Specifically, higher exposure to greenness within 300 metres of the home during pregnancy was associated with higher verbal abilities. In contrast, greater connectivity (density of street intersections) and land use diversity during pregnancy were associated with lower verbal abilities.
