Shift Workers' Health Behavior Action Program Across Europe (SHAPE)

1. Juni 2026 aktualisiert von: Marco Mensink, Wageningen University
This study evaluates the effects of a Combined Lifestyle Intervention Program (CLIP) on sleep, lifestyle behaviors, obesity risk and health in night-shift workers. The primary objective is to assess the effect of the CLIP on objectively measured sleep duration. Secondary objectives include behavioral outcomes related to sleep, diet, physical activity, and stress, as well as body weight and metabolic outcomes, . It is hypothesized that CLIP participants will show a greater increase in sleep duration than controls, alongside favorable changes in lifestyle and health outcomes.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: Intervention
Intervention group receives access to the 24-week combined lifestyle intrevention, which includes the mobile intervention app and four interactive workshops.
The 24-week lifestyle intervention is structured in four 6-week blocks focusing on sleep and stress management or diet and physical activity. Lifestyle advice and behavior change techniques are delivered via a mobile application, complemented by workshops.
Kein Eingriff: Control
The control group receives informational brochures with general advice on the four life-style domains, without active behavioral support. The control group receives access to the combined lifestyle intrevention after the intervention period has ended.
