Key result
Overnight emergency work linked to ~10 mmHg less nocturnal blood pressure dipping than routine days.
Why the study?
The impact of overnight work commitments on circadian blood pressure rhythms in junior medical staff was unclear.
Does overnight work commitment alter circadian blood pressure rhythms in junior medical staff compared to routine working days?
Observational
Does overnight work commitment alter circadian blood pressure rhythms in junior medical staff compared to routine working days?
Effect estimate: 10/11 mmHg less
Overnight work commitments in junior medical staff abolish normal circadian blood pressure rhythms, suggesting these changes are activity-related.

May blunt nocturnal BP dipping in on-call junior doctors; hypothesis-generating and should not yet change practice.
Eg et al. (1992) conducted an observational in Junior medical staff. Overnight work receiving medical emergencies vs. Routine working days was evaluated on Overnight blood pressure fall (10/11 mmHg less). Overnight work commitment receiving medical emergencies caused a loss in normal circadian blood pressure rhythm, with overnight blood pressure falling 10/11 mmHg less than on routine working days.
