Summary
Job stress significantly increases insomnia risk. Factors like high demand, heavy workload, and low social support are linked to sleep disturbances in workers across Europe and Asia.
Area of Science:
- Occupational Health
- Sleep Medicine
- Epidemiology
Background:
- Insomnia is a growing concern for the working population.
- Existing studies suggest a link between job stress and insomnia, but more robust evidence is needed.
Purpose of the Study:
- To conduct a meta-analysis of contemporary literature to reliably assess the correlation between job stress and insomnia.
- To synthesize evidence from prospective and cross-sectional studies in Europe and Asia.
Main Methods:
- Meta-analysis adhering to PRISMA guidelines.
- Inclusion of prospective and cross-sectional studies with available odds ratios.
- Assessment for publication bias and heterogeneity.
Main Results:
- High job stress increases insomnia risk (OR=1.73). Effort-reward imbalance (OR=2.63), high demand (OR=1.35), heavy workload (OR=2.76), and low social support (OR=1.67) are significantly correlated with insomnia.
- Work-family conflict is also linked to insomnia (OR=2.32).
- Subgroup analyses showed similar correlations in males and females. Publication bias was noted for effort-reward imbalance, low social support, and work-family conflict.
Conclusions:
- A significant correlation exists between various job stress factors and insomnia.
- Publication bias and heterogeneity were observed, indicating limitations in the synthesized studies.
- Future research should focus on improved methodologies and underlying mechanisms.

01:27Insomnia
490
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

01:19Management of Insomnia
666
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

01:09Directing Effect of Substituents: meta-Directing Groups
6.0K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

01:15Design of Transmission Shafts - Stress Analysis
746
Designing a transmission shaft requires a thorough understanding of the stresses induced by bending moments and torques, especially in systems where power is transferred through gears. These forces create force-couple systems at the centers of the shaft's cross-sections, leading to both transverse and torsional loading. Although shearing stresses from transverse loads are typically smaller than those from torques and are often overlooked, the significant normal stresses from these loads...

01:21Association Areas of the Cortex
9.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

01:27Associative Learning
1.4K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
