Insights
Obstructive sleep apnea (OSA) is common in obese children who snore. Insulin levels are linked to OSA in this group, suggesting a role in potential cardiovascular issues.
Area of Science:
- Pediatric Endocrinology
- Sleep Medicine
- Metabolic Disorders
Background:
- Obstructive sleep apnea (OSA) is linked to insulin resistance and dyslipidemia in adults.
- Childhood obesity is a growing concern with potential long-term health consequences.
Purpose of the Study:
- To investigate the correlation between obstructive sleep apnea (OSA), serum lipid profiles, and insulin levels in obese children who snore.
- To determine the prevalence of OSA in this pediatric population.
Main Methods:
- Recruitment of obese children with habitual snoring.
- Inclusion of physical examination, overnight polysomnography (PSG), and metabolic studies.
- Diagnosis of OSA based on apnea-hypopnea index (AHI) > 1.0; moderate to severe OSA defined as AHI > 10.
Main Results:
- Ninety-four obese, snoring children (73% male, median age 12.0 years) were studied.
- Sixty subjects (64%) were diagnosed with OSA (47 mild, 13 moderate to severe).
- Logistic regression showed significant associations between OSA and both oxygen saturation nadir and serum insulin levels.
Conclusions:
- Obstructive sleep apnea (OSA) is prevalent in obese children who snore.
- Insulin levels are independently associated with OSA in this pediatric cohort.
- Further research is warranted to explore insulin's role in cardiovascular complications of childhood sleep apnea.
Objective:
In adults, obstructive sleep apnea (OSA) is associated with insulin resistance and dyslipidemia. We aimed to establish correlation between OSA, serum lipid profile, and insulin levels in obese snoring children.
Methods:
Consecutive obese children with habitual snoring were recruited. They underwent physical examination, overnight polysomnography (PSG), and metabolic studies. OSA was diagnosed if apnea hypopnea index (AHI) > 1.0, and cases were considered to have moderate to severe OSA if AHI > 10.
Results:
Ninety-four obese subjects with habitual snoring were studied. Seventy-three subjects were male and the median age of the studied group was 12.0 years (IQR 9.7-13.9). None of the subjects had active cardiopulmonary disease, and the BMI values of our subjects were >95th percentile using local reference charts. Sixty subjects had OSA, 47 being mild, and 13 being moderate to severe OSA. Multiple logistic regression analysis revealed that saturation nadir and insulin levels were significantly associated with OSA.
Conclusion:
OSA is prevalent among obese children with habitual snoring and insulin is independently associated with the condition. Its role in the cardiovascular complications of childhood sleep apnea is worthy of further exploration.
