The impact of participation in the SAGE study on parent behavior

Method This was an analysis of the SAGE nested case-control, comprised of children with asthma (40%), no asthma and no allergy (40%), and rhinitis no asthma (20%). 486 children were seen at 8-10 years and again at 12-13 years. All children were assessed by a pediatric allergist and had skin testing to common aeroallergens. At 8-10 years, the families of children with a positive sensitization to HDM received an information brochure on environmental control for HDM. Parent modification of their home environment was defined as encasement of the child’s mattress or pillow and/or removal of carpet for the child’s bedroom.
