A Genome-Wide Association Study for Post-bronchodilator Lung Function in Children with Asthma

In this study, we conducted a genome-wide association study (GWAS) of post-bronchodilator (BD) FEV1 (forced expiratory volume in 1 second) and FEV1/FVC (forced vital capacity) in Puerto Rican children with asthma. From September 2003 to June 2010, we recruited 618 Puerto Rican children with asthma, which was defined as physician diagnosed asthma and at least one episode of wheezing in the previous year. The recruited children include 267 from public schools in Hartford, Connecticut and 351 from randomly selected households in San Juan, Puerto Rico.]]>
Inclusion criteria included age between 6 and 14 years and having four Puerto Rican grandparents. Exclusion criteria included non-asthma respiratory diseases, and either current smoker or ≥5 pack-years of smoking.]]>
