Reducing Pesticide Exposures in Child Care Centers

Not Applicable

Completed

• Conditions: Environmental Exposure; Children, Only; Risk Reduction
• Interventions: Behavioral: IPM educational workshop and consultation

• Registration Number: NCT03319927
• Lead Sponsor: University of California, San Francisco

Brief Summary

To reduce the risk of adverse health problems associated with chronic exposure to pesticides, a randomized control study will evaluate a nurse-led integrated pest management (IPM) intervention in 88 child care centers serving socio-economically and ethnically diverse preschool-age children in four California counties. Positive changes in IPM knowledge, policies, practices, pests, and pesticide exposure will be assessed.

Detailed Description

The goal of this study is to reduce children's exposure to pesticides in child care centers to improve their long-term health. A randomized-control trial in four northern California counties will compare changes in pesticide exposure among child care centers assigned to an IPM intervention versus an attention control intervention on physical activity. Eighty-eight child care centers serving socio-economically and ethnically diverse preschool-age children will be enrolled. This study will be modeled on a successful nurse-led child care health consultation intervention comprised of an educational workshop, materials and tools, and center-specific consultation over seven months. In addition, the study will include novel methods of measuring pesticide concentrations in child care centers (dust) and to individual children in the child care settings (silicone wristbands). The study aims are to determine if a nurse-led IPM intervention (1) increases child care center staff's IPM knowledge, (2) improves center's IPM policies and practices, (3) reduces pest problems (i.e., pests present, pest residue), (4) increases director's self-efficacy, (5) reduces pesticide exposures in child care center environments, and (6) reduces child-level pesticide exposures in the intervention child care centers compared to the control centers.

Arm && Interventions

Group	Intervention	Description
Integrated pest management	IPM educational workshop and consultation	The intervention consists of an integrated pest management (IPM) educational workshop and consultation. The child care health consultants (CCHCs) conduct the educational workshop for child care center directors and providers on IPM policies and practices including the providers' practices and beliefs. The workshop includes IPM videos, IPM Toolkit, and IPM toolbox. The (CCHCs) meet with center directors to review the results of the Baseline observational Checklists and to identify center-specific intervention goals. The intervention also includes 7 monthly child care health consultation visits where the CCHC and director review the center's progress towards the intervention goals, discuss problems, and share resources.
Physical activity	IPM educational workshop and consultation	The intervention consists of a physical activity educational workshop and consultation. The child care health consultants (CCHCs) conduct the educational workshop for the child care center directors and providers on physical activities center policies and best practices over 7 months. The workshop includes a Physical Activity Toolkit and toolbox. The (CCHCs) meet with center directors to review the results of the Baseline observational Checklists and to identify center-specific intervention goals. The intervention also includes 7 monthly child care health consultation visits where the CCHC and director review the center's progress towards the intervention goals, discuss problems, and share resources.

Primary Outcome Measures

Name	Time	Method
Change in personal pesticide exposures	Before the educational workshop and 9 months after the workshop	Change in the levels of pesticide exposures collected in personal silicone wristbands from baseline to 9 months later. Pesticides will be summarized as mean concentration (ng/mL).
Change in child care center pesticide exposures	Before the educational workshop and 9 months after the workshop	Change in the levels of pesticide exposures collected in dust samples in the child care centers from baseline to 9 months later. Pesticides will be summarized as mean concentration (ng/g) and loading (ng/m2).

Secondary Outcome Measures

Name	Time	Method
Change in the presence of pests or evidence of pests	Before the educational workshop and 9 months after the workshop	Change in the observed # of pests or evidence of pests as part of the IPM Checklist assessment from baseline to 9 months later.
Change in integrated pest management (IPM) policies	Before the educational workshop and 9 months after the workshop	a. Change in the IPM policies identified during an assessment using a standardized Policies Checklist to assess presence of written IPM policy and if present, the quality of the IPM policy.
Change in integrated pest management (IPM) practices	Before the educational workshop and 9 months after the workshop	a. Change in the IPM policies and practices identified during a 2-hour observational assessment using a standardized Policies Checklist and IPM Checklist to assess level of IPM practices from baseline to 9 months later..
