Summary

This trial tests a workplace program designed to encourage local government organizations to adopt sun protection policies for outdoor workers. The program provides education and resources to managers and employees, aiming to increase the use of sun-safe practices. Researchers will compare organizations that receive the program to those that do not, measuring whether formal policies are adopted and whether workers change their sun protection habits. The goal is to reduce skin cancer risk among people who work outdoors.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Sun Safe Workplaces Program (a behavioral intervention promoting sun protection policies and education)
What this could lead to
If effective, this program could help outdoor workers adopt sun-safe habits and reduce their risk of skin cancer.
What could go wrong
The trial is early-stage and relies on voluntary policy adoption, so actual changes in sun protection practices may be limited.
