Lack of Sleep in Childhood Linked to Higher Risk of Early Adult Psychosis
Key Takeaways
- Shorter sleep durations in childhood are linked to higher risk of early adult psychosis.
- Higher interleukin-6 levels partially mediate the sleep-psychosis association.
- Addressing persistent sleep issues in children can mitigate psychosis risk.

Introduction
Recent research has revealed that children who consistently get less sleep are at an increased risk of developing psychotic disorders in their early adulthood. This finding emphasizes the importance of monitoring and addressing sleep patterns in children to prevent potential psychiatric issues later in life.
The Study and Key Findings
The study, published in JAMA Psychiatry, analyzed data from over 12,000 children and nearly 4,000 young adults who participated in the Avon Longitudinal Study of Parents and Children. Researchers tracked nighttime sleep duration from as early as six months old to seven years old and assessed the participants for psychosis disorders and episodes at 24 years of age.
The results were striking: Children who had shorter sleep durations were more than twice as likely to develop a psychosis disorder and nearly four times more likely to experience psychotic episodes in early adulthood.
Role of Inflammation
To deepen their understanding, researchers examined whether inflammation could be a contributing factor. Blood tests measuring interleukin-6 and C-reactive protein levels indicated that higher levels of interleukin-6 at age nine partially mediated the association between shorter sleep duration and psychosis. However, researchers noted that the size of the mediated association was low, suggesting other factors also play a role.
Potential Limitations
The study's findings come with certain limitations. One significant limitation is the reliance on parent- or self-reported sleep data, which might not always match objective sleep measurements. Additionally, the generalizability of the results might be limited as most participants were white, which does not represent the diversity of the general population.
What This Means for Parents
Despite these limitations, the study highlights an actionable insight for parents. Improving children's sleep patterns may mitigate the potential risk of psychosis in early adulthood. As sleep problems are common during childhood, recognizing when these problems become chronic could be crucial in seeking timely help.
Expert Opinions
Dr. Isabel Morales-Muñoz, an assistant professor in psychology at the University of Birmingham, emphasized the importance of addressing persistent sleep issues. She stated, "While persistent lack of sleep may not be the only cause of psychosis in early adulthood, our research suggests that it is a contributing factor, and it is something that parents can address."
The Broader Picture
Previous research has mainly focused on the short-term impact of sleep on psychosis. This study extends our understanding by exploring long-term associations and potential mediating factors like inflammation.
Conclusion
Overall, the research underpins the importance of good sleep hygiene from a young age. While persistent lack of sleep alone isn't the sole culprit for psychosis, it contributes to the bigger picture of psychiatric health.
Future Research
The study advises further exploration into the role of inflammation and other possible mediating factors. Understanding these elements can provide more comprehensive insights and pave the way for preventive measures and early interventions.
Action Steps
Parents should observe and address any persistent sleep issues in their children. Seeking help from healthcare professionals when necessary could be a crucial step in promoting long-term mental health.
