background and objectives: work sampling is a useful technique to characterize how employees allocate their work time to various activities. given the value of nurses’ time for quality health care delivery, characterization of nursing time distribution may provide useful information for optimal use of nursing staff. the purpose of the present study was to explore time allocation by nurses using...

the present study aimed to investigate the characteristics of occupational accidents and frequency and severity of work related accidents in the construction industry among iranian insured workers during the years 20072011.the iranian social security organization (isso) accident database containing 21,864 cases between the years 2007-2011 was applied in this study. in the next step, total accid...

BACKGROUND Overnight operations pose a challenge because our circadian biology promotes sleepiness and dissipates wakefulness at night. Since the circadian effect on cognitive functions magnifies with increasing sleep pressure, cognitive deficits associated with night work are likely to be most acute with extended wakefulness, such as during the transition from a day shift to night shift. MET...

BACKGROUND Mounting epidemiological evidence suggests that night shift work may contribute to the etiology of increased body weight. The present study aimed to examine association between rotating night shift work and body mass index (BMI), and abdominal adiposity respectively among nurses and midwives. METHODS A cross-sectional study was conducted among 724 female nurses and midwives, aged 4...

PURPOSE The study examines the association between exposure to current and cumulative night shift work and subclinical parameters of atherosclerosis. METHODS Participants of a population-based cohort study (the Gutenberg Health Study, N = 15,010) aged 35-64 years were examined at baseline (2007-2012). Investigations included measurements of arterial stiffness, vascular function [reactive hype...

Shift work results in a misalignment between circadian timing and the sleep/wake schedule, leading to irregular and poor quality sleep. Inconsistent input from the daily light cycle further interferes with circadian entrainment. It has been hypothesized that scheduling the sleep/dark cycle on the night shift could aid in promoting adaptation to night shift work by facilitating appropriate phase...

The objective of this paper is to present some recent chronobiological findings related to shift and night worker adaptation. First, some key chronobiological concepts concerning the human species are presented. The authors then discuss the possible impacts of work schedules on shift workers' and night workers' health. Finally, countermeasures that might allow adjusting the workers' biological ...

Effects of shift work on physiological parameters and autonomic nervous-adrenal system were studied on six hospital nurses. Their body temperature, heart rate, blood pressure, fluctuation in ECG R-R intervals, serum catecholamines and cortisol, and subjective fatigue ratings before and after day, evening and night shift were determined. Furthermore, mean heart rates, walk steps, estimated energ...

BACKGROUND It is well known that physicians' night-call duty may cause impaired performance and adverse effects on subjective health, but there is limited knowledge about effects on sleep duration and recovery time. In recent years occupational stress and impaired well-being among anaesthesiologists have been frequently reported for in the scientific literature. Given their main focus on handli...
