Objective:

The aim of this study was to evaluate the effectiveness of a 14-week Total Worker Health®(TWH) intervention designed for construction crews.

The intervention led to significant (P< 0.05) improvements in family-supportive supervisory behaviors (d= 0.72). Additional significant improvements included reported frequency of exercising 30 minutes/day and muscle toning exercise (d= 0.50 and 0.59), family and coworker healthy diet support (d= 0.53 and 0.59), team cohesion (d= 0.38), reduced sugary snacks and drinks (d= 0.46 and d= 0.46), sleep duration (d= 0.38), and objectively-measured systolic blood …
