Objectives Insufficient sleep affects circadian hormonal profiles and inflammatory markers and may modulate attention, executive functioning and decision‐making. Medical professionals and specifically resident physicians, who are involved in long‐term nightshift schedules during their post‐graduate training, are prone to acute and chronic sleep deprivation and disruption, putting them at risk for making medical errors. The aim of the study was to evaluate the impact of chronic and acute‐on‐chronic sleep deprivation and disruption among residents on selected physiological and cognitive measures. Methods Thirty‐three medical and surgical residents were evaluated twice ‐ at baseline and after a 26‐hour shift. Eighteen young attending physicians who did not engage in nightshift schedules served as controls and were evaluated once. Measures included morning cortisol and high‐sensitivity C‐reactive protein (hs‐CRP), computerised tests of attention and behaviour, the Behaviour Rating Inventory of Executive Function, a risk‐taking questionnaire and the Pittsburgh Sleep Quality Index. Results Residents, but not attendings, reported chronic sleep disruption and deprivation. Residents at baseline exhibited reduced morning cortisol levels and elevated hs‐CRP levels, compared to attendings. Residents at baseline had impaired global executive function compared to attendings. A nightshift with acute sleep deprivation further reduced residents' executive function. Residents at baseline and after a nightshift demonstrated increased impulsivity and slower processing time than attendings. Residents and attendings did not differ in risk‐taking tendencies which were assessed in a separate cohort. Conclusions In a real‐life setting, resident physicians exhibit increased low‐grade systemic inflammation (hs‐CRP) and impaired HPA‐axis function. Their chronic sleep curtailment is associated with greater impulsivity, slower cognitive processing, and impaired executive function. Future research is warranted to understand how improving working schedule by increasing sleep duration may minimise the short‐term and potential long‐term risks to physicians in training.

“…In sum, video game playing could have negative consequences in term of sleep quality and health. However Rusnac et al (2018) reported sleep deprivation could also produce or enhance risk-taking and sensation seeking (e.g., in video game playing). In turn, poor sleep quality could maintain and increase video game playing and affect mental health.…”

The aim of this study was to explore sleep quality in a video game population and to prospect the role of different factors such as sociodemographic data, video game duration, intensity of video game playing, and mental and physical health. Two hundred and seventeen participants (24.40 ± 6.98 years old) completed an online questionnaire composed of sociodemographic informations, the Pittsburg Sleep Quality Index (PSQI), the Medical Outcomes Study (MOS SF-36), video game play time per week, and intensity of video game playing as defined by Décamps (AIE-Q). We carried out hierarchical cluster analysis on the 7 dimensions of PSQI to determine sleep quality profiles. Two profiles were found: (1) « High sleep quality profile » for 132 (60.83%) participants, and (2) « Low sleep quality profile » for 85 (39.17%) participants. These two profiles were differently associated with video game duration per week, intensity of video game playing, and mental health. Sleep quality was positively related to mental health and negatively with intensity of video game playing. Intensity of video game playing was a more salient factor to predict poor sleep quality than video game duration.

“…The association between higher risk propensity and sleep/wake pattern disruption reported by O'brien and Mindell [65] may support the assumption according to which risk-takers are more used to sleep deprivation and therefore able to tolerate it better compared to risk-avoiders. Moreover, a study from Rusnac et al [66] demonstrated that chronic sleep deprivation is associated with increased RTB and higher scores on a sensationseeking scale only in subjects who voluntary reduce sleep duration compared to subjects who reduce it involuntarily, i.e. suffering from insomnia.…”

Study Objectives: Night work plays an irreplaceable role in healthcare systems. However, sleep loss due to night shifts can negatively affect healthcare workers′ cognition. Identifying individual variables predicting night shift tolerance may help to mitigate the negative consequences of sleep loss on workers′ and patients′ safety. This study aims to explore, in a healthcare workers′ sample, which variables predict the possible impairment in sustained attention and increase in risk-taking behavior after a night shift. Methods: 22 healthcare workers (avg. age 39.4 ± 11.5 y, 63% females) participated in the experiment. Participants wore a wrist actigraph during a night shift and the preceding 6 days. At the beginning (t0) and at the end (t1) of the night shift, they underwent an assessment of sustained attention (Psychomotor Vigilance Task, PVT) and risk-taking behavior (Balloon Analogue Risk Task, BART). Questionnaires on risk propensity (Domain-Specific Risk Taking, DOSPERT) and on demographics were also administered. Linear regression models were estimated to disentangle the effect of age, risk propensity and actigraphically-defined sleep metrics on cognitive variables. Results: Wake after sleep onset (WASO) significantly predicted t1-t0 PVT metric ″major lapses″ ("β" =-0.11, p=0.0007) while age and DOSPERT significantly predicted t1-t0 BART score ("β" =-0.26, p=0.023 and "β" =-0.097, p=0.043, respectively). Conclusions: Sleep parameters predict the impairment in sustained attention, while the combination of age and risk propensity predicts an increase in risk-taking behavior. The implementation of measures to prevent cognitive decline during night shifts should be designed according to the type of tasks workers must accomplish.

Chronic sleep loss and risk-taking behavior: Does the origin of sleep loss matter?

Abstract: Whether sleep loss is associated with risk-taking behavior or not could depend on the origin of sleep loss and the underlying personality traits.
