Research: Study links immune responses to environmental exposures early in life

According to research, environmental exposures to farm dust, air pollution, and obstetric factors early in life can modify immune response in adolescents. In the study published in the journal Pediatric Allergy and Immunology, there is strong evidence that such exposures early in life may alter the risk of allergic diseases. Exposure to farm environment in childhood even prenatally has been shown to decrease the risk of allergic diseases. Also, being born by cesarean is recognised as a risk factor. The study demonstrated associations between diverse early life exposures and immune responses.
