Ozone pollution increases risk for asthma hospitalization
Published date : 26 Sep 2008
MedWire News: The current levels of ozone pollution in California contribute to an increased risk for hospitalization for children suffering from asthma in the region, US authors conclude.
"Hospitalization and visits to emergency rooms are major contributors to childhood asthma-related health care costs, and account for approximately 12% of care costs for asthma in children 5-17 years old," explained the lead author of the study Kelly Moore (University of California, Berkeley).
Moore and team undertook an ecologic study of hospital discharges for asthma among children aged from birth to 19 years during the high ozone seasons in California's South Coast Air Basin (SoCAB) from 1983 to 2000.
The researchers used hospital discharge data from the State of California, air pollution data from the California Air Resources Board, and demographic data from the 1980, 1990, and 2000 US census.
They found a time-independent, constant effect of ambient levels of O3 and quarterly hospital discharge rates for asthma, and ozone was the only one of five pollutants studied to be associated with increased asthma-related hospital admissions.
The average effect of a 10-ppb mean increase in any given mean quarterly 1-hour maximum ozone level over the 18-year median of 87.7 ppb was a 4.6% increase in hospital discharges for asthma in the same quarter, the authors report.
"Our data support and extend other observations that ambient ozone (highly oxidant, ambient, warm-season environments) causes increases in hospital admissions in children with asthma," they write.
They conclude: "Moreover, the linearity of the relation that we observed indicates that these excess asthma hospital discharges can be expected to continue at levels of air quality experienced in southern California."
The study is published in the journal Environmental Health Perspectives.
