Inspiration from research projects on physical workload in DOC*X

Within DOC*X,  research projects investigate the relationship between physical workload and health, using the PRECISEJEM as the exposure measure.

One research project found an elevated risk of miscarriage associated with work involving both standing, walking and forward bending >30°.

This is just an example of the research conducted within the DOC*X framework. Here you can find more information on other research projects using DOC*X data.
