Insights
Sleep interventions for young children (0-5 years) increased nighttime sleep by 9 minutes per night. These improvements were most effective with sleep-only strategies, not multi-component ones.
Area of Science:
- Pediatrics
- Sleep Medicine
- Evidence-Based Practice
Background:
- Sleep problems are common in children aged 0-5 years.
- Interventions aim to improve sleep duration and quality in this age group.
- Understanding the effectiveness of different intervention types is crucial for clinical practice.
Purpose of the Study:
- To systematically review randomized controlled trials (RCTs) on sleep interventions for children aged 0-5 years.
- To assess the impact of these interventions on nocturnal, daytime, and 24-hour sleep duration.
- To identify intervention characteristics associated with improved sleep outcomes.
Main Methods:
- Searched Medline, EMBASE, and CINAHL databases up to July 2020.
- Included 32 RCTs using subjective and objective sleep measurements.
- Conducted random effects meta-analysis on nocturnal, daytime, and 24-hour sleep duration.
Main Results:
- Sleep interventions increased nocturnal sleep duration by an average of 9 minutes per night (95% CI 4.1 to 13.8).
- Increases were primarily associated with sleep-only interventions.
- No significant changes were observed in daytime sleep duration.
Conclusions:
- Sleep interventions can modestly increase nocturnal sleep duration in young children.
- Future research should focus on sleep-only interventions and utilize objective sleep measures.
- Evidence-based sleep strategies are essential for pediatric health.
Abstract:
This review investigated whether randomised controlled trials attempting to improve sleep or prevent sleep problems in 0-5 year olds influenced nocturnal sleep duration, day-time naps, or 24-h sleep. Medline (Ovid), EMBASE, and CINAHL were searched from inception until 9 July 2020 and supplemented with hand searching. Search results were screened, eligible data were extracted, and risk of bias was assessed by at least two reviewers. Of 8571 publications considered, 32 trials which used a variety of subjective and objective sleep measurements were included in generic inverse variance random effects meta-analysis of nocturnal (n = 24), day-time (n = 14), and 24-h (n = 13) sleep duration. Overall, sleep interventions increased nocturnal sleep duration by a mean of 9 min (95% CI 4.1 to 13.8, I228%) per night when compared with no sleep intervention. Increases were predominantly seen in sleep-only, rather than multi-component interventions. Total 24-h sleep duration tended to increase by a similar amount (8.6 min (95% CI -2.7 to 19.8, I2 = 59%)), but this was mainly only seen in studies that assessed sleep using diaries. There was no evidence that interventions changed day-time sleep duration. Future studies should involve sleep-only rather than multi-component interventions, and use objective sleep measures (reviewregistry857).
