Objective: Mental health problems among medical students have been widely reported, but the predisposing and perpetuating factors and biological concomitants are poorly understood. Adopting a biopsychosocial approach, we studied well-being in a group of Australian medical students, focusing on sleep, autonomic and immune mechanisms, as well as mental, social and physical well-being, health-related behaviours, and daily functioning. Methods: Fourth-year medical students ( N = 151) completed comprehensive assessments, including laboratory-based and nocturnal autonomic monitoring via ambulatory bioharness, a psychiatric diagnostic interview, and questionnaires assessing sleep quality and psychosocial and physical well-being. A blood sample was taken to quantify the inflammatory marker C-reactive protein. Sleep, mood and activity was additionally monitored daily for 7 days. Results: A sizable minority of students reported diminished physical, mental and psychosocial well-being. We also found concerning levels of sleep disturbance and social and occupational impairment in a subset of students. The strong co-occurrence of problems across symptom domains supported a biopsychosocial interdependence of health and well-being states. Maladaptive coping behaviours were apparent, notably hazardous alcohol consumption, which was associated with a clinically significant elevation in C-reactive protein levels (> 3 mg/L). We documented, for the first time, significantly diminished nocturnal heart rate variability in medical students with a mental health diagnosis. Nocturnal heart rate variability was strongly associated with sleep quality, daytime autonomic stress reactivity, as well as occupational and social functioning. Conclusion: Well-being is a multifaceted phenomenon firmly interlinked with sleep, autonomic and immune function, health behaviours and functional outcomes. Our novel findings supported a key role for nocturnal autonomic function in promoting sleep quality and mental well-being. Interventions could focus on sleep hygiene and health behaviours as a buffer for well-being and teach more adaptive strategies for coping with the stresses of medical training.

The quality of nurses’ work has a direct effect on patient health, and poor sleep has been positively associated with nurses’ medical errors. The aim of this study was to investigate the relationship between quality of sleep and heart rate variability (HRV) among female nurses. A descriptive cross-sectional correlational study design was used in January 2014 to study female nurses (n = 393) employed in a medical center in Taiwan. Data were obtained from several questionnaires. HRV was analyzed with five-minute recordings of heart rate signals obtained using a Heart Rater SA-3000P. Approximately 96% of the participants self-reported a poor quality of sleep. Compared to non-shift nurses, significant decreases were found in total power (TP) and low-frequency HRV among shift-work nurses. However, negative correlations were found between sleep quality and HRV, including total power, low frequency, and the low frequency/high frequency ratio (r = −0.425, p < 0.05; r = −0.269, −0.266, p < 0.05). In a stepwise multiple regression analysis, 23.1% of variance in quality of sleep can be explained by TP and heart rate. The sleep quality of female nurses was poor and this affected their autonomic nervous system, which can contribute unfavorable consequences for their health.
