Children who lived near major highways or railroad intersections have higher diagnoses of asthma, says a new study.
Mayo Clinic researchers used this study to show how neighbourhood environment is a risk factor in understanding the development of paediatric asthma.
"Using nearest propensity score, children who lived in census tracts facing the intersection with major highways or railways had about 40 to 70 percent increased risk of developing childhood asthma," says Young Juhn, Mayo Clinic's Department of Community Paediatric and Adolescent Medicine.
