RECLEAN Pilot Study

Purpose

This is an exposure assessment pilot study tailored for families of construction workers living with a child. The investigators will compare home dust metal levels and resident's blood metal levels before and after an educational and environmental intervention. A baseline and a post intervention period assessment will be conducted with home and car lead inspections and risk assessments with collection of dust, urine, blood and toenail samples and a survey. Objectives of this research are to: 1. To characterize pre-intervention home exposures to lead and other metals in households with one construction worker inhabitant living with a child, by assessing household members' biospecimens and home dust metal levels. 2. To develop and evaluate customized home interventions (including environmental and educational approaches) to reduce metals exposure in three tiers of intervention. 3. To characterize home exposures to lead and other metals post intervention and determine adapted behaviors and whether the degree of metals exposure reduction (including take home exposures) in the households depends on the level of intervention.

Arm Groups

ArmDescriptionAssigned Intervention
Active Comparator
Basic intervention group 		Participants in the basic intervention group will have a 1-hour in-home assessment plan and family educational session.
  • Other: In-home assessment plan
    The in-home family educational session provides participants with resources to identify and reduce exposures to metals in the home environment.
  • Behavioral: Family educational session
    The 1-hr in-home family educational session, administered during the first home visit to all participants, adapts a motivational interview model to reduce exposure to metals. this done by empowering families to make informed decisions regarding lead and metal exposures in their home environments that originate from different sources with an emphasis on sources from the workplace. The session will consist of both developing a plan tailored for the home and reviewing educational materials on strategies to reduce exposures in the home, focusing on barriers families experience when attempting to change their behaviors.
Experimental
Intermediate intervention group 		Participants in the intermediate intervention group will have a 1-hour in-home assessment plan and educational session and refer worker to a 1-hr worker take home prevention educational session.
  • Other: In-home assessment plan
    The in-home family educational session provides participants with resources to identify and reduce exposures to metals in the home environment.
  • Behavioral: Family educational session
    The 1-hr in-home family educational session, administered during the first home visit to all participants, adapts a motivational interview model to reduce exposure to metals. this done by empowering families to make informed decisions regarding lead and metal exposures in their home environments that originate from different sources with an emphasis on sources from the workplace. The session will consist of both developing a plan tailored for the home and reviewing educational materials on strategies to reduce exposures in the home, focusing on barriers families experience when attempting to change their behaviors.
  • Behavioral: Worker take home prevention training
    The take home prevention 1-hour educational session guides the worker through 6 simple steps to identify and then prioritize change/s that can be made before leaving work to prevent take-home lead. It has been adapted from the AGILE model for prioritizing tasks. Participants will also be provided with a pamphlet about how to prevent lead from being taken home.
Experimental
Advanced intervention group 		Participants in the advanced intervention group will have a 1-hour in-home assessment plan and educational session, refer worker to a 1-hr worker take home prevention educational session, and provision of D-LEAD all-purpose cleaner and laundry detergent.
  • Other: In-home assessment plan
    The in-home family educational session provides participants with resources to identify and reduce exposures to metals in the home environment.

    D-LEAD cleaner products include hand wipes, all surfaces cleaner and laundry detergent.
