Chronic exposure to ambient ozone and asthma hospital admissions among children
Open accessAbstract
BACKGROUND: The association between chronic exposure to air pollution and adverse health outcomes has not been well studied. OBJECTIVE: This project investigated the impact of chronic exposure to high ozone levels on childhood asthma admissions in New York State. METHODS: We followed a birth cohort born in New York State during 1995-1999 to first asthma admission or until 31 December 2000. We identified births and asthma admissions through the New York State Integrated Child Health Information System and linked these data with ambient ozone data (8-hr maximum) from the New York State Department of Environmental Conservation. We defined chronic ozone exposure using three indicators: mean concentration during the follow-up period, mean concentration during the ozone season, and proportion of follow-up days with ozone levels > 70 ppb. We performed logistic regression analysis to adjust for child's age, sex, birth weight, and gestational age; maternal race/ethnicity, age, education, insurance status, smoking during pregnancy, and poverty level; and geographic region, temperature, and co-pollutants. RESULTS: Asthma admissions were significantly associated with increased ozone levels for all chronic exposure indicators (odds ratios, 1.16-1.68), with a positive dose-response relationship. We found stronger associations among younger children, low sociodemographic groups, and New York City residents as effect modifiers. CONCLUSION: Chronic exposure to ambient ozone may increase the risk of asthma admissions among children. Younger children and those in low socioeconomic groups have a greater risk of asthma than do other children at the same ozone level.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
