Objective:
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.
Research Approach: 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.
Progress Summary:
Conducting Phase 3 data analyses of Phase 2 Cherokee Nation and Nez Perce Tribe data. Collected Phase 2 Navajo Nation school data and will complete school data collection in September 2017. Phase 4 outreach began May 4 2017 with presentation at the National Tribal Forum on Air Quality in Tucson, Arizona. Data analyses involved 12 Cherokee Nation schools and 94 families, and 4 Nez Perce Tribe public schools and 25 families. In Navajo Nation 2 Bureau of Indian Education schools are participating in the study. Navajo Nation family recruitment did not result in adequate number of families for the study, however, increased outreach/education efforts are being initiated in Navajo Nation to more effectively transfer useful information to family members in efforts to better arm them with approaches to reduce asthma triggers within the homes Asthma trigger samples and observations were made three times over the course of the 2015-2016 school year for Cherokee Nation and Nez Perce, and the 2016-2017 school year for Navajo Nation.
Future Activities:
Phase 3 data analysis completion including last round of Navajo Nation school data collection in September 2017, Phase 4 development of outreach and training materials in Year 4, and Phase 5 dissemination of results. Year 4 analysis will include: Navajo Nation final school data input and compilation, QA checks for data entry accuracy including logic and descriptive statistics checks of data normalcy, data analysis and development of findings. Outreach and training activities will include work with Institute of Tribal Environmental Professionals (ITEP) to develop materials and presentations to convey findings and recommendations to tribes across the United States. In addition, development of papers for conferences and journals will start in Phase 4 and continue to Phase 5 dissemination of results. Expected conference presentations will include Indoor Air 2018 July 22-27 in Philadelphia, PA and the Navajo Nation Human Research Review Board Bi-Annual Research Conference, October 18-19 in Window Rock, AZ.
