Presentation Transcript

  1. Risk Factors for Developing Asthma Genetic characteristics Occupational exposures Environmental exposures

  2. Risk Factors for Developing Asthma: Genetic Characteristics Atopy The body’s predisposition to develop an antibody called immunoglobulin E (IgE) in response to exposure to environmental allergens Can be measured in the blood Includes allergic rhinitis, asthma, hay fever, and eczema

  3. Risk Factors for Developing Asthma: Environmental Exposure Clearing the Air: Asthma and Indoor Air Exposures http://www.iom.edu (Publications) Institute of Medicine, 2000 Committee on the Assessment of Asthma and Indoor Air Review of current evidence about indoor air exposures and asthma

  4. Clearing the Air:Categories for Associations of Various Elements Sufficient evidence of a causal relationship Sufficient evidence of an association Limited or suggested evidence of an association Inadequate or insufficient evidence to determine whether an association exists Limited or suggestive evidence of no association

  5. Clearing the Air:Indoor Air Exposures & Asthma Development Biological Agents Sufficient evidence of causal relationship House dust mite Sufficient evidence of association None found Limited or suggestive evidence of association Cockroach (among pre-school aged children) Respiratory syncytial virus (RSV) Chemical Agents Sufficient evidence of causal relationship None found Sufficient evidence of association Environmental Tobacco Smoke (among pre-school aged children) Limited or suggestive evidence of association None found

  6. Clearing the Air: Indoor Air Exposures & Asthma Exacerbation Biological Agents Sufficient evidence of causal relationship Cat Cockroach House dust mite Sufficient evidence of an association Dog Fungus/Molds Rhinovirus Limited or suggestive evidence of association Domestic birds Chlamydia and Mycoplasma pneumonia RSV Chemical Agents Sufficient evidence of causal relationship Environmental tobacco smoke (among pre-school aged children) Sufficient evidence of association NO2, NOX (high levels) Limited or suggestive evidence of association Environmental Tobacco Smoke (among school-aged, older children, and adults) Formaldehyde Fragrances
