Description:

Objective:

The objective of this community-based participatory research project is to evaluate the relationship between early life asthma and traffic-related air pollution.  We are examining this question in a case-control study of asthma persisting to school entry, but with onset earlier in life, in children resident in the same home since before age 2.  We hypothesized that susceptibility to ambient air pollution will vary based on genotype for GSTM1, GSTP1, NQO1, HO-1, and TNFα, genes involved in the biologic response to oxidant air pollutants.  Lifetime exposure will be assessed by calibrating home measurements to the extensive historical exposure assessment from a monitor in each community, which will operate continuously during the lifetime of participants.  Community participation in promoting the study to participants and in data collection and interpretation will enhance both the quality of Center research and the environmental action plans for families of children with asthma in ongoing projects of the community partners.  A steering committee representing university and community research partners and policy makers will work closely with the Community Outreach and Translation Core (COTC) to provide the scientific basis necessary for developing policy for the more widespread protection of children from the effects of air pollution.  

The specific objectives of the research project are to:  (1) identify the population for the proposed case-control study; (2) collect information from parents of participants to assess asthma, activity patterns, and risk factors for asthma, using a structured telephone interview, which also will be administered by Community Study Liaisons; (3) assess the relationship between residential exposure to ambient traffic-related air pollutants and asthma among cases and controls, using information from the Exposure Assessment and Modeling Core; (4) develop tools for assessment of traffic within 100 meters of homes with COTC Neighborhood Assessment Teams composed of community volunteers selected by community research partners; (5) genotype cases and controls for polymorphisms in GSTM1, GSTP1, HO-1, NQO1, and TNFα and assess how these polymorphisms modify the relationship between air pollutants and asthma; (6) assess the burden of asthma-related disease attributable to air pollution in all children living in two communities represented by the community partners, using results from this study and from existing literature; (7) develop a series of community forums with the COTC to discuss the public health burden of air pollution for asthma; (8) integrate new information on air pollution into the environmental action plans developed with families of children with asthma by all community health workers working in service programs of community partners; (9) foster discussion among partners through an active steering committee and through presentation of results at meetings of partner organizations; and (10) participate with the COTC in seminars, community forums, and in the critique of policy initiatives by providing the best scientific evidence available on air pollution and childhood asthma.
