[Differential evaluation of diagnostic criteria for pediatric obstructive sleep apnea hypopnea syndrome]

Area of Science:

• Pediatric Sleep Medicine
• Respiratory Physiology
• Diagnostic Criteria Evaluation

Background:

• Pediatric obstructive sleep apnea-hypopnea syndrome (OSAHS) diagnosis lacks a universally accepted standard.
• Existing criteria like American Thoracic Society (ATS), International Classification of Sleep Disorder (ICSD-3), and Urumqi criterion show variations in identifying affected children.
• The relationship between polysomnography (PSG) parameters and quality of life in pediatric OSAHS is not fully understood.

Purpose of the Study:

• To compare pediatric sleep symptom and quality of life assessments across ATS, ICSD-3, and Urumqi diagnostic criteria.
• To investigate the correlation between PSG findings and the OSA-18 quality of life scale.
• To propose an optimized diagnostic criterion for pediatric OSAHS.

Main Methods:

• Retrospective analysis of 515 children with snoring who underwent PSG.
• Classification of subjects into Sleep Symptom (SS), ICSD-3, and ATS&ICSD groups based on diagnostic criteria.
• Recording of anthropometric data (height, weight, BMI) and OSA-18 quality of life scores.

Main Results:

• Significant differences in weight, BMI, and dysplasia scores were observed between groups.
• Respiratory event indices increased sequentially across SS, ICSD, and ATS&ICSD groups.
• A combined criterion of OAHI ≥ 1/h and LSaO₂ < 92% demonstrated significant differences in respiratory events.

Conclusions:

• The Urumqi criterion, incorporating oxygen desaturation, appears more sensitive in identifying severe pediatric sleep-disordered breathing.
• A refined diagnostic approach for pediatric OSAHS is proposed, integrating respiratory event indices and oxygen saturation levels.
• This approach may improve the identification of children with OSAHS and guide management strategies.
