Non-occupational physical activity levels of shift workers compared with non-shift workers

Objectives

Lack of physical activity (PA) has been hypothesised as an underlying mechanism in the adverse health effects of shift work. Therefore, our aim was to compare non-occupational PA levels between shift workers and non-shift workers. Furthermore, exposure–response relationships for frequency of night shifts and years of shift work regarding non-occupational PA levels were studied.

Methods

Data of 5980 non-shift workers...
