まとめ
夜間食生活 (NEB) は,健康な成人の代謝健康に悪影響を及ぼします. この研究では,NEBは重要な健康指標と睡眠の質を悪化させ,潜在的心代謝リスクを示唆しました.
科学分野:
- 代謝 健康
- 睡眠科学
- クロノバイオロジー
背景:
- 夜間食生活 (NEB) は健康な集団ではあまり研究されていない.
- 代謝パラメータ,肝機能,睡眠に対する潜在的な有害な影響が推測されている.
- シルカディアン障害と神経ホルモンの変化が提案されたメカニズムである.
研究 の 目的:
- 健康な成人の代謝健康に対するNEBの影響を調査する.
- NEBの肝機能,神経ホルモンプロファイル,睡眠の質への影響を調べる
- NEBに関連する潜在的な心代謝リスクを評価する.
主な方法:
- 16人の健康な成人 (18~35歳) を対象とした単一センターのクロスオーバー研究.
- 参加者は2つの1週間の食事レジメントを受け,通常の食事と夜間の食事 (午後9時30分以降の1日カロリーの≥25%) を受けました.
- 臨床的,生化学的,神経ホルモンおよび呼吸器ポリグラフィーデータは,投与後収集された.
主要な成果:
- NEBはアルブミヌリア,血清リン酸,トリグリセリド,C反応性タンパク質 (CRP) を有意に増加させた.
- メラトニンを減少させる一方で, NEBはレプチン,グリリン,コルチゾール,FGF-21およびサイトケラチン-18を増加させた.
- 睡眠試験では,NEBでアプネア・ヒポネア指数 (AHI) と酸素不飽和度が増加した.
結論:
- NEBは,健康な個体における神経ホルモンプロファイルと睡眠に関連する呼吸指標を大幅に変化させます.
- これらの変化は,心臓代謝の健康に有害な影響を及ぼす可能性があることを示唆しています.
- 短期的なNEB評価は健康な被験者でも重大な健康被害を示している.

Cause and Effect

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Insufficient 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.

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
123
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...

Circadian Rhythms and Gene Regulation
4.1K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Management of Insomnia
320
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...

Substance Use Disorders Affecting Sleep
216
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.
