Association Between Severe Obesity and Pediatric Obstructive Apnea-A Retrospective Case Series

Area of Science:

• Pediatric Sleep Medicine
• Obesity Research
• Respiratory Health

Background:

• Pediatric obstructive sleep apnea (OSA) is a significant health concern.
• Obesity is a known risk factor for OSA, but the specific impact of severe obesity requires further investigation.

Purpose of the Study:

• To determine the association between severe obesity and the severity of pediatric obstructive sleep apnea (OSA).
• To evaluate the risk of residual OSA in severely obese children post-adenotonsillectomy.

Main Methods:

• Retrospective case series analysis of 282 children undergoing polysomnography.
• Children were categorized into obesity and severe obesity groups based on BMI percentiles.
• Multiple logistic regression was used to assess the association between severe obesity and severe OSA.

Main Results:

• Severely obese children (53%) showed a higher prevalence of severe OSA (53% vs. 33%) and very severe OSA (24% vs. 11%) compared to those with obesity.
• Severe obesity was independently associated with severe OSA (aOR = 3.44).
• Among patients who underwent adenotonsillectomy, 29% had residual OSA, with Class 3 severe obesity linked to residual OSA (aOR = 4.05).

Conclusions:

• Severe obesity significantly increases the risk and severity of obstructive sleep apnea in children.
• Severely obese children are at a heightened risk for persistent OSA even after surgical intervention.
