RECLEAN Pilot Study

Summary

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.

Conditions

• Lead Poisoning

Interventions

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.
