Summary
Adolescents with behaviorally induced insufficient sleep syndrome (BISS) show increased suicidality. Weekend oversleep is linked to suicidal risk, independent of other factors, suggesting chronic sleep restriction heightens adolescent suicidal risk.
Area of Science:
- Adolescent health
- Sleep medicine
- Mental health research
Background:
- Insufficient sleep is prevalent among adolescents.
- Sleep disturbances are linked to various negative health outcomes.
- Understanding the relationship between sleep and suicidality is crucial for public health.
Purpose of the Study:
- To examine the association between behaviorally induced insufficient sleep syndrome (BISS) and suicidality in adolescents.
- To determine if specific sleep patterns, like weekend oversleep, correlate with increased suicidal ideation.
- To investigate the independence of this association from other factors like depression and daytime sleepiness.
Main Methods:
- A population-based, cross-sectional survey was conducted in the Republic of Korea.
- 8,010 students (grades 7-11) completed questionnaires assessing sleep habits, depression (BDI), and suicidal ideation (SSI).
- Statistical analyses controlled for demographic factors, depression, daytime sleepiness, insomnia, and snoring.
Main Results:
- Adolescents diagnosed with BISS exhibited significantly higher scores on the Beck Scale for Suicidal Ideation (SSI).
- Shorter weekday sleep duration and longer weekend oversleep were significant predictors of higher SSI scores.
- Weekend oversleep remained a significant predictor of suicidality even after accounting for depression, daytime sleepiness, and other sleep issues.
Conclusions:
- Behaviorally induced insufficient sleep syndrome (BISS) is associated with increased adolescent suicidality.
- Weekend oversleep independently predicts suicidality, highlighting its importance beyond depression or sleepiness.
- Findings suggest that chronic sleep restriction in adolescents may elevate suicidal risk, necessitating targeted interventions.

01:13Insufficient Sleep and Sleep Deprivation
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.

01:24Substance Use Disorders Affecting Sleep
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.

01:30Stress and Mental Health
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.

02:04Bullying
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
01:18Depression: Overview
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
01:17Erikson's Theory on Socioemotional Development during Adolescence
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and "What is my place in...
