Pediatric sleep apnea and craniofacial anomalies: a population-based case-control study

Area of Science:

• Pediatric Sleep Medicine
• Craniofacial Anomalies
• Public Health

Background:

• Obstructive sleep apnea (OSA) is a common sleep disorder in children.
• Craniofacial anomalies can impact airway structure and function, potentially increasing OSA risk.
• Population-based data on the association between craniofacial anomalies and OSA in children is limited.

Purpose of the Study:

• To investigate the association between craniofacial anomalies and the diagnosis of obstructive sleep apnea (OSA).
• To determine the strength of this association in a large, population-based sample of children.
• To identify specific craniofacial anomalies most strongly linked to OSA.

Main Methods:

• Retrospective case-control study utilizing Washington State inpatient discharge data (1987-2003).
• Identified 1,203 children with OSA and 6,015 controls without OSA, matched by birth year.
• Used logistic regression to calculate adjusted odds ratios (OR) for associations between congenital anomalies and OSA.

Main Results:

• A strong association was found between any craniofacial anomaly and OSA diagnosis (adjusted OR 38).
• Orofacial cleft (adjusted OR 40) and Down syndrome (adjusted OR 51) showed particularly strong associations with OSA.
• Non-craniofacial malformations were less associated with OSA (adjusted OR 4.1).

Conclusions:

• Congenital craniofacial anomalies are strongly associated with inpatient OSA diagnosis in children.
• This association remains significant after controlling for potential biases.
• Recommends OSA screening for children with craniofacial anomalies.
