Postural change for supine position does not disturb toddlers' nap

Area of Science:

• Pediatrics
• Sleep Medicine
• Public Health

Background:

• Sudden unexplained death in childhood (SUDC) is a concern, prompting preventative measures like the "Back to Sleep" campaign (BSC).
• Japanese nurseries routinely adjust toddlers' sleeping positions from prone to supine during naps as a SUDC preventative strategy.
• The BSC recommendations, applied to infants over one year old since 1996, aimed to decrease SUDC rates.

Purpose of the Study:

• To investigate if forced postural changes from prone to supine during toddler naps disturb sleep.
• To assess the impact of a common SUDC preventative measure on young children's sleep quality in a nursery setting.

Main Methods:

• Fifty-two toddlers (18.4 ± 3.3 months) were monitored for 8 hours using actigraphy and accelerometers to track sleep status and body position (prone, supine, lateral).
• Nursery staff manually repositioned 24 toddlers from prone to supine during naps.
• Wake-sleep status and duration of awakenings after positional changes were recorded.

Main Results:

• Manual repositioning from prone to supine resulted in minimal or no waking for toddlers.
• When awakenings occurred, they were brief (3.1 ± 4.9 minutes), with toddlers quickly returning to sleep.
• The majority of toddlers did not experience significant sleep disturbance due to the positional adjustments.

Conclusions:

• Manual adjustment of toddlers' sleeping position from prone to supine does not negatively impact their sleep during naps.
• This practice, implemented as a potential SUDC prevention method, appears safe and minimally disruptive to toddler sleep.
• Findings support the continued use of positional adjustments in nurseries as a SUDC preventative measure without compromising sleep quality.
