ارتباط بین بیخوابی و استرس شغلی: یک متاآنالیز Association between insomnia and job stress: a meta-analysis

Introduction Insomnia is the most common sleep disorder, having become one of the foremost health concerns for workers internationally. Over the previous 30 years, a large number of epidemiological studies have investigated and reported on the correlation between insomnia or sleep disturbance and stressors in the workplace. Knudsen [16] investigated 1715 full-time employees, identifying a close relationship between work overload and insomnia, while role conflict, as well as job latitude, was correlated with difficulty in maintaining sleep. A further investigation [25] involving 1786 workers from 8 electrical appliance factories, applying both DCS and ERI on the same population, illustrated the significant association between job stress and insomnia symptoms. Comparable conclusions have also been drawn in other research [13, 14, 26, 30, 31]. Nevertheless, the distinctions between these findings were readily apparent, while in certain studies, the estimated confidence intervals of effects were too wide to draw meaningful conclusions. Moreover, an array of instruments was adopted for measuring exposure and results among the literature, with the majority of studies being of a cross-sectional nature, where a sole study is believed to lack strength in terms of validity and dependability. In this research, we undertook a comprehensive search and analysis of the literature concerned with the correlation between insomnia symptoms measured by scales and job stress variables, as a means of producing evidence with greater reliability. Additionally, we used meta-analyses to summarize the varied literature from Europe and Asia that was both prospective and cross-sectional by design, accounting for the deficiencies in the breadth of evidence within previous research.
