从多基因风险到自杀的途径:酒精使用障碍和童年逆境的影响
medRxiv : the preprint server for health sciences
|February 23, 2026
概括
自杀企图 (SA) 的遗传风险部分是由酒精使用障碍 (AUD) 解释的,特别是儿童时期的低逆境. 了解这些途径是预防自杀策略的关键.
科学领域:
- 遗传学 是一个遗传学.
- 精神病学是一个精神病学.
- 流行病学 流行病学
背景情况:
- 自杀念头 (SI) 和自杀企图 (SA) 是复杂的,受遗传,行为和环境因素的影响.
- 酒精使用障碍 (AUD) 和不良童年经历 (ACE) 可能在遗传倾向自杀中发挥作用.
研究的目的:
- 调查SI和SA的多基因分数 (PGS) 对终身自杀倾向的预测值.
- 检查AUD的调解作用和ACEs在导致自杀的遗传责任中的调节作用.
主要方法:
- 利用了来自10,275名参与者的数据 (类似非洲和类似欧洲的遗传祖先).
- 对SI和SA的测试PGS与终身SI和SA相比.
- 通过AUD评估调节,通过ACEs评分评估调节.
主要成果:
- 在SA PGS显著预测SA在两个祖先群体 (p < 2e-16).
- SI PGS没有预测SI (p > 0.55).
- AUD调解了SA的遗传风险 (p < 2e-16),间接影响被ACE得分减弱 (p < 2e-16为AFR,p = 0.03为EUR).
结论:
- 对SA的遗传责任部分由AUD调解,特别是在童年逆境较低的个体中.
- 显而易见的病因途径有助于自杀倾向,突出了AUD作为基因危险个体干预的潜在目标.

Stress and Mental Health
1000
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Human Genetics

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.

Psychological and Sociocultural Causes of Schizophrenia
697
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Stress Prevention and Stress Management Techniques IV
283
Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Bulimia Nervosa
852
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Depressive Disorders: Etiology
770
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
