Association of salivary cortisol with chronomics of 24 hours ambulatory blood pressure/heart rate among night shift workers

24 Hours chronomics of ambulatory blood pressure and its relation with circadian rhythm of 6-sulfatoxy melatonin in night shift health care workers

“…This pattern was reversed in night-shift workers. 12,13 Identical blood pressure and heart rate have been observed among night shift workers.…”

Association between shift work, salivary cortisol levels, stress and fatigue in nurses: integrative review

“…[16][17][18] Nursing professionals, due to long working hours in assorted shifts, are specially susceptible to chronic stress and fatigue, whose consequences, on the long run, amount to desynchrony of the HHA axis and consequent physical and mental disease, work capability decrease, occupational accident increase, and absenteeism. [19][20][21][22] Considering the aforementioned, the goal of this study was to identify, in Brazilian and international literature, scientific evidence on the correlation of work in shifts and alterations to cortisol circadian rhythm, stress levels, and fatigue in nursing workers.…”

“…19,28 No articles were found which concomitantly evaluated fatigue, stress and salivary cortisol levels in nurses.…”

“…[29][30][31][32][33] In addition, there was no consensus regarding the evaluation of cortisol secretion, so two studies chose to analyze it in predetermined occasions 19,28 and two used standard indexes of cortisol secretion such as CAR and the area under the curve (AUC). 7 Another possible explanation for data inconsistency is the low sample number of the studies.…”

“…In the reviewed articles, the description of evaluation criteria to collection protocol adherence were direct, such as providing a notebook for each participant with collection instructions, 19 or indirect, such as a minimum CAR of 2.5nmol/l. 7 countless studies in literature mention mechanisms to monitor adherence to sample collection protocols by participants, such as using electronic devices, sending telephone messages, and emphasizing the importance of the research.…”
