Brief Summary

The current project is a safety and health intervention focused on sleep and fatigue among truck driver teams (pairs), where one driver sleeps in a moving vehicle while the other partner drives. This study is conducted within the Oregon Healthy Workforce Center (OHWC), a NIOSH Center of Excellence in Total Worker Health. We will evaluate engineering and behavioral interventions to improve sleep, reduce fatigue, and impact Total Worker Health. An enhanced cab intervention will alter whole body vibrations during driving and sleep periods, and includes a therapeutic mattress system and an active suspension seat. The enhanced cab will be evaluated alone and in combination with a behavioral sleep intervention adapted from our effective SHIFT (Safety \&Health Involvement For Truckers) program. The interventions prioritize hazard reduction according to the hierarchy of controls, and will be evaluated with a randomized controlled design.

Study Arms (2)

Intervention

EXPERIMENTAL

All participants in the intervention arm will receive two interventions: an enhanced cab intervention alone, and then the enhanced cab conditions combined with a behavioral sleep intervention.

Other: Enhanced Cab; Behavioral: Fit4Sleep

Control

NO INTERVENTION

Usual practices with regards to cab conditions and access to workplace programs for preventing sleep and fatigue problems.

Interventions

Enhanced Cab OTHER

The enhanced cab intervention includes the introduction of an active suspension seat and a therapeutic mattress system. After a baseline phase, the intervention arm will receive the enhanced cab intervention alone, and then the enhanced cab plus a behavioral sleep program.

Intervention

Fit4Sleep BEHAVIORAL

The behavioral sleep program includes a friendly dyad-based physical activity competition; self-monitoring and logging of physical activity, sleep hygiene behaviors, and sleep; and individual coaching. The behavioral sleep program includes an optional body weight management component. The intervention arm will receive the behavioral sleep program in combination with the enhanced cab intervention.
