Shift Workers' Health Behavior Action Program Across Europe (SHAPE)
18 de agosto de 2026 actualizado por: 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.
