Clinical Trial Summary

In this intervention study, the investigators engage Vietnamese American nail salon owners to train workers within their salons on how to reduce workplace chemical exposures. The long-term goal of the study is to reduce toxic chemical exposures in nail salons and promote worker health and safety in this vulnerable worker population.


Description:

The primary hypothesis is that there will be a significantly greater reduction in measured levels of air contaminants among workers in the intervention group than in the comparison group. The primary outcome of interest is workplace chemical exposure reduction.

In addition, the secondary hypotheses are:

1. The proportion of workers who have increased knowledge of workplace chemical exposure reduction (WCER) will be significantly greater in the intervention group than in the comparison group.

2. The proportion of workers who report having modified behavioral and environmental factors that facilitate WCER will increase significantly more in the intervention group than the comparison group.

3. The proportion of workers with decreased work-related health problems will be greater in the intervention group than the comparison group.

As part of the secondary analyses, the investigators will also examine whether changes in knowledge and behavior are associated with workplace chemical exposure reduction and also whether changes in workplace chemical exposure are associated with improved health. The specific aims are to:

1. Enhance existing workplace chemical exposure reduction (WCER) education materials and survey instruments that target Vietnamese nail salon owners and workers.

2. Implement an owner-to-worker intervention to administer the WCER education materials.

3. Evaluate the effectiveness of the owner-to-worker WCER intervention for:

1. reducing the primary outcome of measured personal levels of air contaminants (e.g., toluene, methyl methacrylate, methyl ethyl ketone, and total volatile organic compounds) in workers;

2. influencing the secondary outcomes which include:

i) increasing worker knowledge of WCER

ii) modifying behavioral and environmental factors that promote WCER
