[Cardiovascular risk factors and metabolic shift workers in a population of railway workers]

Cardiovascular and metabolic risk factors prevalence is studied with an increasing interest, involving also working-age people, Several studies had evidenced that shift-work is a key factor in the etiology of cardiovascular illnesses. Railway workers--especially those who are involved in the monitoring of rail traffic--are often shift-workers. Their shift-schedule is based on a rotation of--in this order--afternoon, morning and night. Regarding the important role played by this kind of workers for the public safety, the evaluation of their cardiovascular risk is of utmost importance. In this study we evaluated the prevalence of cardiovascular risk factors in railway shift-workers to define prevention strategies.
