Insights
Children with sleep-disordered breathing (SDB) undergoing adenotonsillectomy show higher obesity rates compared to the general pediatric population. Obese African American children are also more likely to have SDB.
Area of Science:
- Pediatric Health
- Sleep Medicine
- Obesity Research
Background:
- Sleep-disordered breathing (SDB) is a growing concern in pediatric populations.
- Obesity is a significant comorbidity associated with various health issues in children.
- Adenotonsillectomy is a common surgical intervention for SDB in children.
Purpose of the Study:
- To compare the prevalence of obesity in children with SDB undergoing adenotonsillectomy against the general pediatric population.
- To identify potential risk factors for SDB in obese children, particularly within specific ethnic groups.
Main Methods:
- A cross-sectional controlled study design was employed.
- Body-mass-index (BMI-for-age) percentiles were assessed for children with SDB and matched controls.
- Statistical analyses included t tests, chi-squared analysis, and logistic regression to compare groups and estimate risk factors.
Main Results:
- The study included 299 children, with 56.9% diagnosed with SDB.
- Children with SDB exhibited higher rates of obesity (46% vs. 33%) and underweight (8% vs. 3%) compared to controls.
- A significant association was found between obesity and SDB in African American children (OR, 2.22; P < 0.01).
Conclusions:
- Children with SDB requiring adenotonsillectomy are disproportionately more likely to be obese than their peers in general pediatric clinics.
- Obesity presents a heightened risk for SDB among African American children.
- These findings highlight the critical link between pediatric obesity and sleep-disordered breathing.
Objectives:
To compare the prevalence of obesity in children with sleep-disordered breathing (SDB) who undergo adenotonsillectomy to that in the general pediatric population.
Design:
Cross-sectional controlled study.
Methods:
A body-mass-index (BMI-for-age) percentile was determined for children with SDB and for matched controls from a general pediatric clinic. Children who were obese (>85th %) were analyzed. Groups were compared using a t test or chi(2) analysis. Risk factors were estimated with logistic regression.
Results:
The study population included 299 children, of whom 170 (56.9%) had SDB. Compared with controls, more children with SDB were obese (46% vs 33%, P = 0.029) or underweight (8% vs 3%, P = 0.110), and fewer children with SDB were healthy weight (46% vs 64%, P = 0.002). Among African American children, those who were obese were more likely to have SDB (OR, 2.22, P < 0.01).
Conclusions:
Children with SDB who undergo adenotonsillectomy are more likely to be obese than children seen in a general pediatric clinic. African American children who are obese are more likely to have SDB.
