Insights
REM-related obstructive sleep apnea (OSA) affects over half of children with OSA. Female gender and sleeping in a supine position are key risk factors for this condition in children.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Medicine
- Clinical Research
Background:
- Obstructive sleep apnea (OSA) in children presents with varying mechanisms and sleep stage distributions.
- Understanding REM-related OSA is crucial for effective diagnosis and management.
Purpose of the Study:
- To determine the prevalence of REM-related obstructive sleep apnea (OSA) in children.
- To identify risk factors associated with REM-related OSA in pediatric populations.
Main Methods:
- A retrospective, cross-sectional study involving 366 children diagnosed with OSA via polysomnography (PSG).
- REM-related OSA defined by an obstructive apnea-hypopnea index (OAHI) in REM sleep at least twice that during NREM sleep.
Main Results:
- The prevalence of REM-related OSA was 50.3% in the studied children.
- Children with REM-related OSA were more likely to be female and less likely to have adenotonsillar hypertrophy.
- Independent risk factors identified were female gender and supine sleep position, with associated findings of lower nadir SpO2 and higher ODI3%.
Conclusions:
- REM-related OSA is highly prevalent in children, affecting over half of those diagnosed with OSA.
- OAHI during REM sleep is an important metric for future pediatric OSA research.
- Identifying REM-related OSA can inform targeted interventions and management strategies.
Objectives:
Different pathophysiological mechanisms and the distribution of respiratory events among rapid eye movement (REM) and non-rapid eye movement (NREM) sleep modulate the effect of obstructive sleep apnea (OSA). We aimed to study the prevalence and risk factors for REM-related OSA in children.
Study Design:
Retrospective, cross-sectional study.
Methods:
We recruited 366 children with OSA confirmed by polysomnography (PSG) over a 5-year period. REM-related OSA is defined by an obstructive apnea-hypopnea index (OAHI) in the REM sleep ≥2× than during NREM sleep.
Results:
The prevalence of REM-related OSA in children was 50.3%. Children with REM-related OSA were more likely to be female (P = 0.042), and had lower prevalence of adenotonsillar hypertrophy (P = 0.043) compared with children with other OSA subtypes. Children with REM-related OSA slept longer in the supine position (P = 0.003), had shorter duration of NREM1 sleep (P = 0.018), lower nadir SpO2 (P = 0.005), and a higher oxygen desaturation index 3% (ODI3%) (P = 0.014), and lower arousal index (P = 0.034) compared with other OSA subtypes. Female gender and supine sleep was the independent risk factors for REM-related OSA.
Conclusion:
The prevalence of REM-related OSA was 50.3%. OAHIREM should be considered as an important parameter in future clinical research studies done in children with OSA.
