Brief Summary:
The burden of childhood asthma is borne disproportionately by children living in poverty and in urban centers many of whom are from communities of color and are at greater risk for environmental exposures Given the complex interaction of physical and social environmental factors on childhood asthma there have been increasing calls for comprehensive efforts using a community-based participatory research CBPR approach Community Action Against Asthma is a long standing CBPR partnership in Detroit Michigan composed of representatives from community-based organizations health and human service agencies and academia All members of the partnership have been actively involved in the development of the CBPR project proposed here The specific aims are 1 to test the efficacy of air filters AFs separately and when combined with air conditioners ACs to reduce exposure to particulate matter PM over and above a standard community health worker home visit standard intervention 2 to test the association between any reduction in PM exposure through the use of AFs separately and when combined with ACs over and above a standard intervention and health outcomes in children with asthma 3 to elucidate the causal pathways by which any intervention-related improvements in childrens asthma-related health status is occurring One hundred and fifty households in Detroit Michigan with at least one child with mild persistent or moderate to severe persistent asthma will be enrolled to participate in the study Households will be randomly assigned to one of three groups a standard household intervention or control group an AF only intervention group or an AFAC intervention group Extensive health and exposure measures will be undertaken during the course of the 12 -month intervention Given the role of PM in childrens asthma-related health and the higher concentrations of PM in microenvironments there is a need to test the efficacy and efficiency of novel approaches to reducing indoor air pollutants Doing so using a CBPR approach will enhance the relevance and ultimately the success of this proposed research
Detailed Description:
For the proposed study we will conduct a randomized controlled trial RCT comparing a standard community health worker home visit intervention the standard intervention to an Air FilterAF only intervention that adds the use of an AF in the childs bedroom to the standard intervention AF only intervention and an Air FilterAF Air Conditioner AC intervention that adds the use of an AF and AC in the childs bedroom to the standard intervention AFAC intervention Figure 1 We will test whether the addition of AFs and in the warmer months ACs to the standard intervention as compared to the standard intervention will 1 further lower childrens exposure to PM Specific Aims 1a 1b and 2 further improve asthma-related health status of children Aims 2a 2b One hundred and fifty Detroit households with at least one child aged 6 to 12 with symptoms consistent with persistent asthma mild moderate or severe will be enrolled in the study Following collection of baseline data households will be randomly assigned to receive one of three interventions the standard household intervention the AF only intervention or the AFAC intervention Participants assigned to the AF only intervention group will receive AFs at the start of the 12-month intervention SummerFall 2008 Those assigned to the AFAC intervention group will receive AFs at the start of the intervention period but ACs will not be in place during the first summer of the intervention but will be installed in June 2009 prior to the second summer of the intervention Figure 2 Data will be collected across all seasons Fall 2008 through Winter 2009 which will enable us to evaluate directly the exposure and health outcome effects Specific Aims 1a and 2a respectively of the addition of AFs alone to the standard intervention as well as the exposure and health outcome effects of the AFs augmented by ACs Aims 1b 2b This design will also allow for comparisons adjusted for any changes in the exposure and health status of the intervention groups of the combined effect of the AC and AF to that of the AF alone
