By improving indoor air quality  (IAQ) and reducing environmental asthma triggers this study intends to reduce  asthma symptoms related to tribal home-&-school childhood exposures.  The study will demonstrate the importance of  a total exposure approach based on traditional ecological knowledge (TEK).   TEK from 3 tribes in different  regions/climates will refine education, source control of allergens by targeted  cleaning and other asthma trigger removal activities, ventilation and air  cleaning interventions that reduce asthma triggers.


Observational pre-test/post-test study with  matched case-control to determine impact of asthma trigger reduction  interventions on asthma symptom days.  The  interventions are based on developing a deeper understanding and respect for  the living and non-living interactions in and between school and home  environments that is the hallmark of TEK.   The attention to both school  and home environments will embody a more complete profile of total exposure of  the tribal children throughout the day.

Expected Results:

The number of days that  tribal school children with asthma are absent from school each year are  expected to decrease 45% or 2.5 days because of fewer asthma symptom days.
