This study examines the relationshipbetween childhood exposure to air pollution and diagnosis with chronic non-respiratoryhealth outcomes in adulthood. This prospective cohort study uses data collectedin the 1970-1980s from 395 children, including exposure to air pollution. Overthirty years later, a survey collected data on various health outcomes,including diagnosis with arthritis, high blood pressure, long-term skinconditions, and hay fever allergies. Logistic regression modeling was performedto examine the relative contribution of childhood exposure to air pollution onchronic non-respiratory health outcomes in adulthood. Childhood exposure to SO2 emerged as a significant predictor of arthritis OR = 2.73, 95% CI 1.20 - 6.18 and high blood pressure OR = 2.82, 95% CI 1.23 - 6.47. Other significant predictorsinclude respiratory symptoms during childhood, family income during childhoodand adulthood, property tenure, employment status, residential exposures, lifeevents, physical activity, and body mass index. Childhood exposure to airpollution did not emerge as a significant predictor of long-term skinconditions or hay fever allergies. Findings contribute to the debate on thehealth effects of air pollution, indicating that the health impacts ofchildhood exposure to air pollution may include chronic inflammatory disordersin adulthood.
