Air pollution, urgent asthma medical visits and the modifying effect of neighborhood asthma prevalence.

ABSTRACT:

Background

Social and environmental stressors may modify associations between environmental pollutants and asthma symptoms. We examined if neighborhood asthma prevalence (higher: HAPN vs. lower: LAPN), a surrogate for underlying risk factors for asthma, modified the relationship between pollutants and urgent asthma visits.

Methods

Through zip code, home addresses were linked to New York City Community Air Survey's land use regression model for street-level, annual average nitrogen dioxide (NO₂), particulate matter (PM_2.5), elemental carbon (EC), summer average ozone (O₃), winter average sulfur dioxide (SO₂) concentrations. Poisson regression models were fit to estimate the association (prevalence ratio, PR) between pollutant exposu
