Air pollution and health effects: a study of medical visits among children in Santiago, Chile

Article Abstract:

Air pollution and weather health effects in children have been studied through use of time-series analyses of 2 years of daily visits to primary health care clinics in Santiago, Chile. Counts for upper or lower respiratory symptoms for cohorts 3-15 years of age and below age 2 were computed. Under age 2 a 50-microgram/cu m change in particulate matter below 10 micrometers in diameter (PM(sub.10)) was associated with a 4-12% increase in lower respiratory symptoms. For children 3-15 years of age, the increase in lower respiratory symptoms was 3-9% for a 50-microgram/cu m change in PM (sub.10) and 5% per 50 ppb ozone change.
