Objective:
The CBPR Intervention Project currently consists of two projects. The first project is an evaluation of a building-wide Integrated Pest Management (IPM) program in public housing. The project is a collaboration between the New York City Department of Health and Mental Hygiene (NYCDOHMH), the NYC Housing Authority (NYCHA), and the Columbia Center for Children’s Environmental Health (CCCEH). The aim of this project is to examine the impact of IPM on pest populations, allergen levels, and asthma morbidity up to 6 months after the intervention and is currently funded by a no-cost extension. The second project continues the NYCHA–NYCDOH–CCCEH collaboration, examining the long-term impact of NYCHA’s IPM intervention. The aim of the second project is to determine the duration of IPM effectiveness by measuring how long IPM keeps pest levels reduced, how long the physical repairs, sealing and caulking last before degrading, and the maintenance schedule needed to maintain IPM.
Progress Summary:
Data collection for our 6 month IPM evaluation at both sites is complete. We enrolled 324 apartments at baseline, 264 at 3-month follow-up, and 264 at 6-month follow-up, retaining 81% of participants. The final apartment was enrolled in Bushwick, Brooklyn in Spring 2006. We were able to collect follow-up data on134 apartments. There were 65 apartments that were ineligible for follow-up due to NYCHA error in scheduling the interventions.
Multi-level modeling, controlling for baseline, buildings (as buildings were assigned to treatment and control), and senior vs. mixed age buildings were used in the analyses of allergen and pest variables using SAS Proc Mixed.
IPM apartments did better than control apartments in controlling cockroaches and mice according to every measure of effectiveness we assessed. There was a clearer impact on cockroaches than mice, and it was stronger at 3 months compared to 6 months. IPM was significantly more successful than controls apartments in reducing cockroach counts 25%, 50%, and 75% by the 3-month follow-up. IPM apartments had, on average, between 6 and 24 fewer cockroaches trapped per week than control apartments with between 10 and 100 cockroaches trapped per week.
We found statistically significant reductions in the cockroach allergen levels in the intervention apartments (IPM) compared to the control apartments (traditional pest control services of NYCHA), both in the kitchen (P=.05) and in the bedroom (P=.013) 6 months after the baseline. However, the measurements of cockroach allergens were not statistically significant using the same models at the 3-month measurement taken after baseline in both the bedroom AND the kitchen. Cockroaches were detected in 77% of all apartments.
Significance
This study demonstrates that IPM is an effective method for safely controlling pests in a public housing environment. Asthma is a major health problem among low-income, inner-city minority populations. This intervention has successfully shown that there are safe methods to control prevalent pests without the use of highly toxic pesticides. This may have large scale implications in the control of asthma triggers for residents of public housing. One unique characteristic of this study was the use of NYCHA personnel to perform the IPM. NYCHA staff did not provide an educational intervention and positive results were still evident. High asthma prevalence among residents and the use of illegal pesticides highlights the need for safe and effective building-wide pest control strategies. Our analyses of the impact of IPM has demonstrated that a community-based, building-wide IPM intervention in public housing can reduce pest populations and allergen levels in the home. The long term IPM evaluation will provide much needed information about the long-term impact and durability of IPM interventions and hopefully be able to demonstrate the cost effectiveness of IPM.
Future Activities:
Analyses of the impact of IPM on pests, allergens, asthma morbidity, and pesticide use are underway for the follow up. Results from the 3 and 6 month data have been analyzed and are being prepared to submit for publication.
The final lab analyses of the allergen samples collected for long term follow up will be completed this summer and the overall assessment of the long term effectiveness of IPM will be evaluated later this year. We are preparing data on program costs for the intervention from NYCHA. A follow-up manuscript reporting the long term results, which will most likely include a cost effectiveness analysis, is planned for the Fall/Winter of 2006.
