Why the study?

Shift work increases cardiovascular risk, and autonomic dysfunction has been proposed as an explanatory link.

Does shift work reduce cardiac autonomic activity as assessed by HRV compared to day work?

Population

30 shift workers and 30-day workers

Comparison

Shift workers vs day workers

Implication

Shift work associated with lower HRV; hypothesis-generating for autonomic mediation of cardiovascular risk, requiring prospective confirmation.

Structured PICO

Does shift work reduce cardiac autonomic activity as assessed by HRV compared to day work?

P
Population
60 workers (30 shift workers and 30 day workers)
I
Intervention
Shift work schedule
C
Comparator
Day work schedule
O
Outcome
Cardiac autonomic activity assessed by time-domain measures of short-term Heart Rate Variability (HRV) including RMSSD and pNN50surrogate

Shift work is associated with reduced cardiac autonomic activity, particularly in males, which may contribute to increased cardiovascular risk.
