Research Category: Children's Health , Health Effects
Description:
Objective:The objective is to evaluate the impact of “Healthy Homes” interventions on the reduction of pesticide exposure to farmworker children.
Progress Summary:Focus groups were held in January and February 2001 with farmworkers, foremen/women, and growers to prioritize intervention study ideas and determine their feasibility. These focus groups helped guide a successful grant submitted to the National Institute of Environmental Health Sciences (NIEHS) to provide additional funding for the intervention study. Additionally, statistical analysis of prenatal home visit and baseline questionnaire data is in progress that will support the planned intervention activities.
Research Changes
As discussed in earlier annual reports, we reduced the Intervention Study to a pilot project due to increased costs associated with the implementation of managed care in Monterey County, California. In the last year we conducted a number of focus groups and community contacts to further refine the Intervention Study and prepare additional grants to fully implement our intervention, outreach, and education goals. While an earlier grant to the California Endowment Foundation was not funded due to program priority changes, we successfully prepared an RO1 level application to NIEHS under the Community Based Intervention Research Program. This Intervention Study is modeled on our original Center application but will develop a technical intervention involving protective clothing and handwashing as well as home-based education to address pesticide exposures. Budgeted Intervention resources from the Center grant will support laboratory analysis of environmental and biological samples for the newly funded intervention grant.
New Funded Research and Outreach Initiatives
To accomplish our objective to build a true Center for Children’s Environmental Research, we have initiated the following new research activities to fully utilize the specimens and expertise we have developed:
- We have received an RO1 level award from NIEHS to conduct a fully developed Intervention Study.
- In collaboration with the U.S. Environmental Protection Agency National Exposure Research Laboratory (NERL), we will be conducting intensive environmental sampling for a group of 20 farmworker children. This investigation will include several media in addition to those we originally proposed. See discussion of the Quantitative Pesticide Exposure Assessment (QEA) in the 2001 Annual Report for R826709C001.
Future activities will include the following:
- Initiate the Intervention Study activities, including focus groups, questionnaire development, data analysis, and pilot studies in support of the technical interventions.
- Finalize Human Subject approvals and initiate blood lead analysis by state health department.
- Ship stored blood samples to the University of Washington for paroxonase polymorphism studies.
