Insights
Childhood obstructive sleep apnoea (OSA) lacks standardized definitions and diagnostic criteria, hindering research. International collaboration is needed to advance understanding of OSA complications and treatments.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Medicine
- Clinical Research
Background:
- Childhood obstructive sleep apnoea (OSA) is a growing concern with potential long-term health impacts.
- Current literature presents challenges due to varying definitions and diagnostic methods.
- Evidence links childhood OSA to cardiovascular and neurocognitive issues.
Purpose of the Study:
- To conduct a comprehensive literature review on the epidemiology, complications, diagnosis, and treatment of childhood obstructive sleep apnoea.
- To identify gaps in current knowledge and highlight areas for future research.
Main Methods:
- A systematic literature search was performed using MEDLINE up to July 2004.
- Keywords included 'obstructive sleep apnoea syndrome', 'children', 'epidemiology', 'complications', 'treatment', and 'polysomnography'.
- Relevant literature and data were reviewed by the authors.
Main Results:
- A scarcity of normative data exists for childhood obstructive sleep apnoea.
- Inconsistent definitions and diagnostic criteria impede study comparisons.
- Polysomnography remains the gold standard for diagnosis, but criteria lack standardization and long-term outcome correlation.
- Surgical intervention is the primary treatment, with alternative therapies under investigation.
Conclusions:
- Limited consensus exists regarding the definition, diagnosis, and long-term sequelae of childhood obstructive sleep apnoea.
- International collaborative research with standardized, evidence-based definitions and polysomnographic criteria is crucial for progress.
Objective:
To review literature on epidemiology, complications, diagnosis, and treatment of childhood obstructive sleep apnoea.
Data Source:
Literature search of MEDLINE up to July 2004 using the following key words: 'obstructive sleep apnoea syndrome', 'children', 'epidemiology', 'complications', 'treatment', and 'polysomnography'.
Study Selection:
Literature and data related to the aspects of childhood obstructive sleep apnoea.
Data Extraction:
Relevant information and data were reviewed by the authors.
Data Synthesis:
There is a paucity of normal data on childhood obstructive sleep apnoea. Varying definitions and diagnostic criteria have been used in different studies, making direct comparison difficult. However, a small-scale local study found that the prevalence and clinical features of this condition were similar to data published overseas. Increasing evidence suggests that childhood obstructive sleep apnoea is associated with cardiovascular morbidity and neurocognitive dysfunction. Overnight polysomnography has remained the gold standard for diagnosing obstructive sleep apnoea but the diagnostic criteria has not been standardised nor correlated with the long-term outcome. Surgical intervention has remained the treatment of choice, although alternative therapies are being evaluated.
Conclusion:
Consensus on the various important aspects of childhood obstructive sleep apnoea is still limited, especially the definition, diagnosis, and long-term sequelae of this condition. Further advances can only be made with international collaborative research, using evidence-based definitions, standardised techniques, and polysomnographic criteria.
