まとめ
交代的なシフト勤務,特に夜勤のシフト勤務は 体重増加や動脈硬化などの 心血管疾患のリスクを高めます 夜勤を減らすことにより,これらの健康への悪影響が軽減される可能性があります.
科学分野:
- 労働衛生について
- 心血管医学
- 生理学
背景:
- 産業ではシフト制労働が一般的であり,心臓血管の健康に影響を及ぼす可能性があります.
- シフト労働者における心血管疾患 (CVD) リスク因子に関する縦断的なデータは限られている.
- これらの変化を理解することは 対象を絞った健康対策の開発に不可欠です
研究 の 目的:
- 絶対値とCVDリスク因子の6年間の変化を評価する.
- 産業用シフト労働者 (高/低夜間負荷) と昼間労働者の間のこれらの変化を比較する.
- シフトワークの特徴とCVDリスク因子の進行との関連を特定する.
主な方法:
- 3つの産業グループにおける6年間の追跡調査:夜勤労働者が多く,夜勤労働者が少なく,昼勤労働者が多く.
- データ収集には,人口統計,血圧,心拍数,頸動脈内膜厚み (cIMT),頸動脈から股関節の脈波速度 (cfPWV),V̇O2max,脂質,HbA1c,CRPが含まれていた.
- 縦断的な変化と群差を分析するために混合モデルを使用した.
主要な成果:
- 夜勤労働者は体重,cfPWV,CRPの増加を示した.
- 夜勤労働者と昼間の労働者は,cIMTの増加を示した.
- すべての労働者は,シフト勤務の年数に関連して,V·O2maxの減少とHbA1cの増加を経験しました.
結論:
- 交代的なシフト労働,特に夜勤は体重増加,炎症,動脈硬化,cIMT,HbA1c,およびV̇O2maxの減少と関連しています.
- 夜勤を短縮し,休憩時間を組み込むような戦略は,CVDのリスクを減らすことができます.
- シフトワークは 積極的な管理を必要とする 重要な心臓血管健康問題です

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:13Insufficient Sleep and Sleep Deprivation
210
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.

77
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.

01:26Factors Affecting the Risk of Infection
12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:23Insulation Coordination
226
Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times...
