概括
对失眠,睡眠短暂和长时间睡眠的遗传倾向与较低的教育程度,基于知识的职业和收入有关. 这些睡眠特征显著影响人力资本发展.
科学领域:
- 人类遗传学和人口健康
- 睡眠科学和时间生物学
- 社会经济因素和人力资本
背景情况:
- 睡眠对认知功能,恢复和人力资本发展至关重要.
- 了解睡眠特征的遗传基础可以阐明它们对社会经济结果的影响.
- 以前的研究表明,睡眠与各种生活结果之间存在联系,但遗传关联需要进一步调查.
研究的目的:
- 调查失眠,睡眠短暂和长时间睡眠的多基因指数 (PGI) 与教育程度,职业群体和收入之间的关联.
- 探索潜在的因果途径,将遗传睡眠倾向与人力资本结果联系起来.
- 为了区分特定睡眠特征 (失眠,短暂,长时间睡眠) 与一般睡眠时间的影响.
主要方法:
- 利用了来自芬兰6个25-64岁人口队列 (1992-2017,N=20,121) 的注册表数据.
- 采用回归模型来评估睡眠特征PGI和人力资本结果之间的关联.
- 应用了带有仪器变量 (PGI) 的扩展回归模型,以隔离对表型睡眠特征和随后结果的遗传倾向影响.
主要成果:
- 不眠症 (IPGI),短睡眠 (SSPGI) 和长睡眠 (LSPGI) 的多基因指数显示,与教育成就和进入知识工作的选择有显著的负面关联.
- 这些与收入的关联在很大程度上通过教育和职业团体进行了调解.
- 仪器化表型睡眠特征,由各自的PGI预测,证实了教育和知识工作的负因果途径.
结论:
- 对失眠,睡眠短暂和长时间睡眠的遗传倾向与人力资本发展的减少密切相关.

Insufficient Sleep and Sleep Deprivation
833
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.

Circadian Rhythms and Gene Regulation
4.5K
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...

Substance Use Disorders Affecting Sleep
400
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.

Human Genetics
1.4K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Understanding Sleep
1.4K
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Longitudinal Research
13.1K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
