Metabolic alterations in children with obstructive sleep apnea

Area of Science:

• Pediatric Endocrinology
• Sleep Medicine
• Metabolic Disorders

Background:

• Rising obesity rates in children are a significant public health concern.
• Obesity is increasingly linked to Obstructive Sleep Apnea (OSA) even in young children.
• Understanding metabolic alterations associated with obesity and OSA is crucial for pediatric health.

Purpose of the Study:

• To investigate the association between metabolic variables, including insulin resistance, and Obstructive Sleep Apnea (OSA) in obese children.
• To evaluate how insulin resistance and glucose metabolism are affected in young obese children with OSA.

Main Methods:

• Retrospective case-control study conducted at a tertiary care children's hospital.
• Analysis of data from obese children (aged 2-12 years) who underwent polysomnography and laboratory testing.
• Inclusion criteria: obese children (BMI z score >95th percentile) with available lipid profiles, fasting glucose, and insulin levels.

Main Results:

• No significant differences in lipid profiles or blood pressure between children with and without OSA.
• Patients with OSA exhibited significantly higher fasting insulin, blood glucose, and HOMA scores (p<0.01).
• Apnea-Hypopnea Index (AHI) correlated with insulin and glucose homeostasis alterations; fasting insulin and HOMA predicted severe OSA.

Conclusions:

• Metabolic alterations in glucose and insulin are associated with the severity of OSA in young obese children.
• These findings highlight the link between metabolic dysfunction, OSA severity, and potential cardiovascular disease risk in pediatric populations.
• Early identification and management of OSA in obese children may be important for mitigating metabolic complications.
