Growing up near natural green space may reduce the risk of allergy at age 3 years

A novel study published in mSystems special issue has provided new evidence that living near to natural green space in infancy may reduce a child's risk of developing inhalant allergies in early childhood and that it may be mediated by gut microbes.

The study on 699 children from the Edmonton site of the CHILD Study found that living near natural green space was protective against the development of multiple inhalant allergies at age 3 years. This association appeared to be mediated by changes to Actinobacteria diversity in infant stools samples taken at 4 months of age. The findings highlight the importance of promoting natural urban greenspace preservation to improve child health by reducing atopic disease susceptibility and point to a novel causal role of reduced Actinobacteria diversity on atopic sensitization development.
