Want to ensure your child hits their expected developmental milestones? New UBC research suggests living in areas with high exposure to greenspace can help set them up for success.
For the study, researchers at the UBC faculty of medicine and faculty of forestry analyzed the developmental scores of 27,372 children in Metro Vancouver who attended kindergarten between 2005 and 2011. They estimated the amount of greenspace around each child’s residence from birth to age five. They also assessed levels of traffic-related air pollution and community noise.
The results highlight the fundamental importance of natural green spaces like street trees, parks and community gardens, authors say.
“More research is needed, but our findings suggest that urban planning efforts to increase greenspace in residential neighbourhoods and around schools are beneficial for early childhood development, with potential health benefits throughout life,” says the study’s senior author Dr. Matilda van den Bosch, assistant professor in UBC faculty of medicine’s School of Population and Public Health.
“Time in nature can benefit everyone, but if we want our children to have a good head start, it’s important to provide an enriching environment through nature contact. Access to greenspace from a very young age can help ensure good social, emotional and mental development among children,” she adds.
According to the researchers, the reason for this is partly greenspaces’ ability to reduce the harmful effects of air pollution and noise—environmental challenges that have been shown to adversely affect children’s health and development through increased stress, sleep disturbances and central nervous system damage.
The researchers assessed early childhood development using the Early Development Instrument (EDI), a survey completed by kindergarten teachers for each child. The tool measures a child’s ability to meet age-appropriate developmental expectations.
The study, published recently in The Lancet Planetary Health, includes contributions by researchers at the University of California Berkeley, University of California Los Angeles, Barcelona Institute for Global Health, BC Children’s Hospital and BC Centre for Disease Control.
