“…The Socio-demographic characteristics questionnaire assessed age, gender, weight, size, occupational group, education level, family situation, work characteristics, physical activity, and quantity of sleep. Sleep quality, well-being and perceived stress at work and at home are evaluated using visual analogue scales (VAS), i.e., by moving a cursor on a horizontal, non-calibrated line of 10 cm, ranging from very low (0) on the left to very high (10) on the right [ 44 , 45 , 46 , 47 , 48 , 49 ]. We also looked for the presence of other addictions such as tobacco, cannabis, and alcohol.…”

Purpose of the study: Work addiction risk is a growing public health concern with potential deleterious health-related outcomes. Perception of work (job demands and job control) may play a major role in provoking the risk of work addiction in employees. We aimed to explore the link between work addiction risk and health-related outcomes using the framework of job-demand-control model. Methods: Data were collected from 187 out of 1580 (11.8%) French workers who agreed to participate in a cross-sectional study using the WittyFit software online platform. The self-administered questionnaires were the Job Content Questionnaire by Karasek, the Work Addiction Risk Test, the Hospital Anxiety and Depression scale and socio-demographics. Data Analysis: Statistical analyses were performed using the Stata software (version 13). Results: There were five times more workers with a high risk of work addiction among those with strong job demands than in those with low job demands (29.8% vs. 6.8%, p = 0.002). Addiction to work was not linked to job control (p = 0.77), nor with social support (p = 0.22). We demonstrated a high risk of work addiction in 2.6% of low-strain workers, in 15.0% of passive workers, in 28.9% of active workers, and in 33.3% of high-strain workers (p = 0.010). There were twice as many workers with a HAD-Depression score ≥11 compared with workers at low risk (41.5% vs. 17.7%, p = 0.009). Sleep quality was lower in workers with a high risk of work addiction compared with workers with a low risk of work addiction (44.0 ± 27.3 vs. 64.4 ± 26.8, p < 0.001). Workers with a high risk of work addiction exhibited greater stress at work (68.4 ± 23.2 vs. 47.5 ± 25.1) and lower well-being (69.7 ± 18.3 vs. 49.3 ± 23.0) compared with workers at low risk (p < 0.001). Conclusions: High job demands are strongly associated with the risk of work addiction. Work addiction risk is associated with greater depression and poor quality of sleep. Preventive strategies should benefit from identifying more vulnerable workers to work addiction risk.

“…Out of these eight selected clinical trials, four of them assessed the role of shift work as a cause of circadian misalignment in cardiac diseases [6,7,8,9]. Five among them assessed the sleeprelated issues like insomnia, obstructive sleep apnea and lack of sleep as a contributing factor in cardiac diseases [8,10,11,12,13].…”

“…They can all contribute to developing cardiovascular morbidity [25,26]. If shift work is combined with stressful situation, it leads to even more frequent and persistent tachycardia, as was demonstrated by Dutheil et al They monitored emergency physicians during a 14-shift and a 24-hours shift, and they showed frequent episodes of tachycardia reaching even up to 180 bpm and the cardiac stress was twice on the shift day compared to the non-shift days [9].…”

Around 121.5 million people suffer from cardiovascular diseases globally. The risk of cardiovascular diseases increases with advancing age in both genders. Circadian rhythm is responsible for a streamlined functioning of various body functions. Certain functions and hormones have their peak levels according to the biological day or night of circadian rhythm. Shift work and sleep disorders like obstructive sleep apnea can cause circadian misalignment that affects different metabolic, immunological, and cardiovascular functions, which ultimately increases the risk of cardiovascular diseases. We systematically searched the online database PubMed to find papers on randomized controlled trials (RCTs) from the past five years, evaluating the role of shift work and different sleep disorders in causing circadian misalignment and its effect on the risk of cardiovascular diseases. Fifty papers were shortlisted, and after the application of various inclusion and exclusion criteria, 18 papers were chosen; and then after a thorough analysis of the text, eight papers were selected for the review. All papers were evaluated for quality. Two papers focused on the effect of shift work on cardiovascular diseases, whereas five papers evaluated the role of sleep disorders on circadian rhythm and the risk of cardiovascular diseases. Shift work and sleep-related disorders were found to cause circadian misalignment, and it was found to be associated with an increase in the risk of cardiovascular diseases. Managing these disorders can help reduce the risk of cardiovascular diseases.

“…During normal night sleep, the sympathetic nervous system is at its nadir. During a busy night shift in the ED, the converse is true: Studies of emergency physicians working at night have shown elevated heart rate, blood pressure, stress response, and prevalence of tachydysrhythmias [53-55]. The association of night shift work and increased risk of certain cancers has led to the International Agency for Research on Cancer to classify shift work that involves circadian disruption as a probable human carcinogen [56,57].…”

Night shift preparation, performance, and perception: are there differences between emergency medicine nurses, residents, and faculty?

Objective Determine differences between faculty, residents, and nurses regarding night shift preparation, performance, recovery, and perception of emotional and physical health effects. Methods Survey study performed at an urban university medical center emergency department with an accredited residency program in emergency medicine. Results Forty-seven faculty, 37 residents, and 90 nurses completed the survey. There was no difference in use of physical sleep aids between groups, except nurses utilized blackout curtains more (69%) than residents (60%) and faculty (45%). Bedroom temperature preference was similar. The routine use of pharmacologic sleep aids differed: nurses and residents (both 38%) compared to faculty (13%). Residents routinely used melatonin more (79%) than did faculty (33%) and nurses (38%). Faculty preferred not to eat (45%), whereas residents (24%) preferred a full meal. The majority (>72%) in all groups drank coffee before their night shift and reported feeling tired despite their routine, with 4:00 a.m. as median nadir. Faculty reported a higher rate (41%) of falling asleep while driving compared to residents (14%) and nurses (32%), but the accident rate (3% to 6%) did not differ significantly. All had similar opinions regarding night shift-associated health effects. However, faculty reported lower level of satisfaction working night shifts, whereas nurses agreed less than the other groups regarding increased risk of drug and alcohol dependence. Conclusion Faculty, residents, and nurses shared many characteristics. Faculty tended to not use pharmacologic sleep aids, not eat before their shift, fall asleep at a higher rate while driving home, and enjoy night shift work less.
