Based on satellite data from 1985 to 2013, researchers from Aarhus University mapped the presence of green space around the childhood homes of almost one million Danes from birth to the age of 10 and compared this data with the risk of developing one of 16 different mental disorders in adulthood, xinhuanet.com wrote.
Risk for subsequent mental illness for those who lived with the lowest level of green space during childhood was up to 55 percent higher across various disorders compared with those who lived with the highest level of green space, said the study, published Monday in the journal Proceedings of the National Academy of Sciences of the United States of America.
"Green space throughout childhood is therefore extremely important," said lead researcher Kristine Engemann, a postdoctoral fellow in the Department of Bioscience and the National Centre for Register-based Research at Aarhus University.
As of 2018, 55 percent of the world's population was living in urban areas, and the proportion is expected to increase to 68 percent by 2050, according to the 2018 Revision of World Urbanization Prospects produced by the Population Division of the United Nations (UN) Department of Economic and Social Affairs.
In view of the growing urban population as well as the ever increasing stress of urban life, the researchers suggested that integrating natural environments into urban planning is a promising approach to improving mental health and reducing the rising global burden of psychiatric disorders.
