Intervention on Coronary Risk Factors by Adapting a Shift Work Schedule to Biologic Rhythmicity
The effects of a new shift rotation schedule on coronary risk factors was assessed in a short-term intervention trial in 45 volunteer policemen that were divided into two groups. They worked 4 weeks each on their customary schedule (counter-clockwise rotation) and on the new schedule (clockwise rota...

The effects of a new shift rotation schedule on coronary risk factors was assessed in a short-term intervention trial in 45 volunteer policemen that were divided into two groups. They worked 4 weeks each on their customary schedule (counter-clockwise rotation) and on the new schedule (clockwise rotation). Serum lipids, glucose, uric acid, blood pressure, nocturnal urinary excre-tion of catecholamines, the quality and quantity of sleep, and tobacco consumption were assessed before, during, and after each schedule. During clockwise rotation, serum levels of triglycerides (but not cholesterol), and of glucose (but not uric acid) were significantly lower than during counter-clockwise rotation. Sleep was reported to be longer and better with clockwise rotation, but tobacco consumption did not differ between the two schedules.
