Clinical predictors of pediatric obstructive sleep apnea: Demographic and physical factors

Area of Science:

• Pediatric Sleep Medicine
• Otolaryngology
• Respiratory Medicine

Background:

• Obstructive sleep apnea (OSA) is a common sleep disorder in children.
• Identifying clinical predictors aids in early diagnosis and management of pediatric OSA.
• Level I polysomnography (PSG) is the gold standard for OSA diagnosis.

Purpose of the Study:

• To determine clinical factors predicting obstructive sleep apnea (OSA) in pediatric patients.
• To analyze the relationship between clinical variables and polysomnography (PSG) parameters in children.
• To investigate age-specific predictors of OSA severity.

Main Methods:

• Retrospective analysis of children aged 12 years or younger undergoing level I PSG.
• Correlation and multiple linear regression analyses to identify predictors of the apnea-hypopnea index (AHI).
• Subgroup analysis comparing preschool-aged (<6 years) and school-aged (≥6 years) children.

Main Results:

• Older age, male sex, higher tonsil grade, and higher BMI percentile were associated with increased AHI in the overall pediatric cohort.
• Tonsil grade was the sole significant predictor of AHI in preschool-aged children.
• In school-aged children, age and BMI percentile became significant predictors, with a reduced influence of tonsil grade.

Conclusions:

• Clinical factors including older age, male sex, tonsillar hypertrophy, and obesity are significant predictors of OSA severity (AHI) in children.
• The relative importance of predictors varies with age: tonsillar hypertrophy is more critical in younger children, while age and BMI gain importance in older children.
• Age-tailored clinical evaluations are essential for accurately assessing OSA risk in pediatric populations.
