Abstract

Background

Shift work with sleep disruption is a systemic stressor that may possibly be associated with blood pressure dysregulation and hypertension.

Purpose

We hypothesize that rotation to a simulated night shift with sleep deprivation will produce blood pressure elevations in persons at risk for development of hypertension.

Method

We examined the effects of a simulated night shift on resting blood pressure in 51 diurnal young adults without current hypertension. Resting blood pressure was monitored throughout a 24-h period of total sleep deprivation with sustained cognitive work. Twelve participants (23.5%) reported one or more parents with a diagnosis of hypertension. Ten participants were classified as prehypertensive by JNC-7 criteria. Only two prehypertensive subjects reported parental hypertension.

Results

Results indicate that, as the night shift progressed, participants with a positive family history of hypertension showed significantly higher resting diastolic blood pressure than those with a negative family history of hypertension (p = 0.007). Prehypertensive participants showed elevated blood pressure throughout the study.

Conclusion

These data suggest that rotation to a simulated night shift with sleep deprivation may contribute to blood pressure dysregulation in persons with a positive family history of hypertension.
