Sleep Interventions and the Prevention of Pediatric Anxiety: A Systematic Review
Clinical Snapshot
PICO Framework
| P — Population | Children, adolescents, and young adults with sleep problems or at risk of anxiety disorders |
| I — Intervention | Sleep interventions (including cognitive behavioural therapy for insomnia, behavioural sleep interventions, and related sleep health programmes) |
| C — Comparator | Control conditions (waitlist, treatment as usual, or no intervention — inferred; not explicitly detailed in abstract) |
| O — Outcomes | Anxiety symptoms, anxiety disorder onset/prevention, and anxiety sensitivity as a mechanistic outcome |
Bottom Line
This systematic review synthesises evidence from 21 paediatric intervention and experimental studies, finding consistent directional support for sleep interventions reducing anxiety symptoms and preventing anxiety disorder onset in children and adolescents. The introduction of anxiety sensitivity as a mechanistic pathway is a theoretically important contribution that warrants prospective investigation. However, the review's clinical utility is constrained by the absence of meta-analytic pooling, formal risk of bias assessment, GRADE certainty ratings, and a transparently reported search strategy. The evidence is promising but not yet definitive. For Australian clinicians, brief behavioural sleep interventions — particularly CBT-based approaches — represent a low-risk, accessible, and scalable preventive strategy that aligns with existing Medicare and RACGP frameworks for paediatric mental health. Clinicians should consider sleep assessment as a routine component of anxiety risk evaluation in children. Practice change should be incremental and guided by emerging RCT evidence rather than this review alone. A notable bibliographic concern: the DOI provided does not correspond to this publication and should be verified before citation.
Key Findings
P Value: Not reported
Effect Size: Not reported — no pooled effect size provided; narrative synthesis only
Primary Outcome: Sleep intervention reduced anxiety symptoms, anxiety disorders, and the onset of anxiety disorders across 21 paediatric intervention and experimental studies
Nnt Or Sensitivity: Not calculable from available data; no NNT, relative risk, or odds ratio reported. Three additional mechanistic studies supported anxiety sensitivity as a mediating pathway between sleep problems and anxiety development
Confidence Interval: Not reported
Clinical Application
Sleep interventions — particularly brief behavioural and CBT-based approaches — are described as scalable and implementable in psychiatric practice. Low resource requirements and the modifiable nature of sleep make this a pragmatically attractive preventive target. However, workforce capacity, access to trained clinicians, and family engagement remain implementation barriers. In Australia, paediatric anxiety disorders represent a significant burden, with approximately 1 in 7 children affected (Australian Institute of Health and Welfare data). CBT-based sleep interventions align with RACGP guidelines for paediatric mental health and may be delivered under Medicare-funded Mental Health Treatment Plans (up to 20 sessions per calendar year). The Better Access initiative supports psychologist-delivered CBT, including sleep-focused components. TGA-approved pharmacological sleep aids for children are limited, making behavioural sleep interventions the preferred first-line approach. School-based delivery models are particularly relevant given Australia's investment in headspace and school mental health programmes. Indigenous Australian children, who face disproportionate rates of both sleep disruption and anxiety, represent an important equity consideration not addressed in this review. Children, adolescents, and young adults presenting with sleep disturbance who are at risk of developing anxiety disorders; particularly relevant in primary care, paediatric psychiatry, and school-based mental health settings
Abstract
PURPOSE OF REVIEW: Anxiety disorders are prevalent in children, adolescents, and young adults. As many youth either do not receive adequate intervention or do not achieve remission, prevention of anxiety disorders is a public health priority. Sleep problems are a modifiable risk factor that precedes anxiety. This systematic review includes recent pediatric sleep interventions and anxiety outcomes, and introduces anxiety sensitivity as an understudied mechanism. RECENT FINDINGS: In 21 intervention and experimental studies, sleep intervention reduced anxiety symptoms/disorders and the onset of anxiety disorders. Three additional recent studies examined anxiety sensitivity in the relationship between sleep problems and anxiety, supporting the inclusion of anxiety sensitivity in future research studies. Sleep health is a scalable, accessible target for reducing anxiety and is an important part of pediatric anxiety prevention. Sleep treatments can be brief and implemented in psychiatric practice. Future research studies should consider anxiety sensitivity as a potential mechanism.
