Does Chronic Exposure to Air Pollution in Childhood Impact Long-Term Respiratory Health?

This study seeks to examine the relationship between childhood exposure to air pollution and long-term respiratory health and to identify significant predictors of respiratory health in adulthood. Logistic regression modeling was undertaken using health and exposure data for 395 participants who resided during childhood in four distinct neighborhoods in Hamilton, Ontario, Canada. Significant predictors include exposure to SO2 in childhood, location of residence in childhood, sex, residential and occupational histories, stressful life events, and respiratory health in childhood. This study suggests that the health impacts of childhood exposure to air pollution are located beyond the short-term period that most research addresses.
