Annual SO₂ exposure, asthma, atopy, and lung function in Puerto Rican children.

ABSTRACT:

Background

Long-term effects of sulfur dioxide (SO₂ ) exposure on children, a vulnerable population, are largely unknown. Further, how long-term SO₂ affects Puerto Rican children living in the island of Puerto Rico, a group with high asthma prevalence, is unclear. We evaluated the effects of annual average 1-hour daily maximum SO₂ average on asthma, atopy, total immunoglobulin E (IgE), and lung function in Puerto Rican children.

Methods

A cohort of 678 children (351 with asthma, 327 without asthma) was recruited in Puerto Rico from 2009 to 2010. Annual average 1-hour daily maximum SO₂ exposure was interpolated utilizing publicly available monitoring data. Multivariable logistic and linear regression was used for the analysis of ast
