Summary
Night shift hospital workers gain an average of 5kg and have poor diets. Occupational health nurses can help prevent these health risks through early identification and intervention.
Area of Science:
- Occupational Health
- Metabolic Health
- Dietary Science
Background:
- Night work is prevalent in hospital settings.
- Weight gain and metabolic complications are known effects of night shifts.
- Cardioprotective diet is often insufficient among night shift workers.
Purpose of the Study:
- To quantify weight gain in night shift hospital workers compared to day shift workers.
- To assess the dietary habits of night shift workers.
- To highlight the role of occupational health nurses in prevention.
Main Methods:
- Comparative analysis of weight changes between night and day shift workers.
- Dietary assessment focusing on cardioprotective factors.
- Identification of occupational health nurse interventions.
Main Results:
- Night shift workers experienced an average weight gain of 5kg compared to day shift workers.
- Night shift workers demonstrated insufficient intake of cardioprotective foods.
- Occupational health nurses are crucial for early detection and primary prevention.
Conclusions:
- Night shift work in hospitals is associated with significant weight gain and poor dietary patterns.
- Early identification of these risks by occupational health nurses is vital.
- Proactive primary prevention strategies are needed to mitigate adverse health outcomes.

Substance Use Disorders Affecting Sleep
230
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Insufficient Sleep and Sleep Deprivation
230
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Management of Insomnia
328
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...

Sleep Apnea
228
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Fatigue
255
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...
