Title of Collaborative Activity: |
National Health and Nutrition Examination Survey 2005-2006, Allergy Component, Interagency Agreement with CDC/NCHS |
Description of Collaborative Activity: |
This collaborative project developed and implemented an allergy/asthma focused component for the National Health and Nutrition Examination Survey (NHANES). The allergy component, included in NHANES 2005-2006, enabled a more robust and generalizable investigation of the role of allergen/endotoxin exposures and IgE-mediated sensitization in allergic diseases than previously possible, increasing the knowledge of complex relationships between allergen and endotoxin exposures, allergic sensitization and allergic diseases, including asthma. This survey component queried on allergy and asthma prevalence and symptoms, measured levels of common indoor allergens and endotoxin in household dust, and quantified total and 19 allergen-specific immunoglobulin E levels in serum of study participants. |
