Insights
Obese children with obstructive sleep apnea (OSA) have higher residual OSA after adenotonsillectomy (T&A). Underweight children often achieve normal weight status post-surgery, improving sleep apnea outcomes.
Area of Science:
- Pediatric Otolaryngology
- Sleep Medicine
- Pediatric Obesity
Background:
- Obstructive sleep apnea (OSA) is a common condition in children.
- Adenotonsillectomy (T&A) is a primary treatment for pediatric OSA.
- The impact of body weight status on T&A outcomes requires further investigation.
Purpose of the Study:
- To assess the influence of preoperative body weight status on surgical outcomes after T&A in children with OSA.
- To evaluate changes in body weight status post-T&A in relation to OSA treatment effectiveness.
Main Methods:
- A cohort of 161 children diagnosed with OSA via polysomnography was studied.
- Children were categorized into four weight groups: underweight, normal, overweight, and obese based on BMI.
- Surgical outcomes, including apnea/hypopnea index (AHI) and oxygen saturation, were compared across weight groups.
Main Results:
- All weight groups showed significant improvements in AHI and oxygen saturation post-T&A.
- Obese children exhibited a significantly higher incidence of residual OSA (75%) compared to other groups.
- Over half (54%) of underweight children transitioned to normal weight status within six months post-surgery.
Conclusions:
- While T&A improves sleep parameters for all weight statuses, obese children face a higher risk of persistent OSA.
- Adenotonsillectomy can positively impact weight status, particularly for underweight children, leading to normal weight.
Objective:
To investigate the impacts of body weight status on surgical outcomes and shifts of body weight status after adenotonsillectomy(T&A) in children with obstructive sleep apnea (OSA).
Methods:
From 2009 to 2011, 161 children (mean age, 7.0 ± 3.4 years; 78% boys) were included. All the children had clinical symptoms and preoperative polysomnographic evaluations diagnosis of OSA. Children were divided into four weight status groups (underweight, normal weight, overweight and obese), based on age and gender corrected body mass index (BMI).
Results:
Following T&A, the four different weight status groups significantly improved in apnea/hypopnea index (AHI) and minimum oxygen saturation. However, 49.1% of the children (79/161) had residual OSA (AHI ≥ 1). The incidence of residual OSA (AHI ≥ 1) in the obese group was 75%, which was significantly higher than the other three groups (P<0.01). Weight status changes after T&A were documented, and 54% (13/24) of the underweight children shifted to normal weight status within 6 months after surgery.
Conclusion:
Although sleep parameters improved in all weight statuses, obese children had a higher incidence of residual OSA postoperatively. About half of the underweight children shifted to normal weight status after T&A.
