Insights
Pediatric obstructive sleep apnea (OSA) is more severe in boys and increases with age, particularly in male adolescents. Obesity significantly elevates the apnea-hypopnea index (AHI) in children with OSA.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Physiology
Background:
- Age and gender disparities in polysomnographic findings for pediatric obstructive sleep apnea (OSA) are not well understood.
- Understanding these differences is crucial for accurate diagnosis and management of OSA in children.
Purpose of the Study:
- To determine age and gender-related characteristics in pediatric obstructive sleep apnea (OSA).
- To analyze polysomnographic findings across different pediatric age groups and by gender.
Main Methods:
- Retrospective analysis of polysomnographic data from 1842 children.
- Data categorized into age groups: 3-6, 6-9, 9-12, 12-15, and 15-18 years.
- Comparison of apnea-hypopnea index (AHI) based on age, gender, and obesity status.
Main Results:
- The apnea-hypopnea index (AHI) showed a trend of increasing with age (p=0.002).
- Boys consistently had a higher AHI than girls across all age groups (p<0.001).
- Obesity was associated with a significantly higher AHI compared to non-obese children (p<0.001).
- AHI increased with age in boys but not significantly in girls.
- Gender moderated the association between obesity and AHI, and between age and AHI in older adolescents.
Conclusions:
- Male gender and obesity are significant risk factors for pediatric obstructive sleep apnea (OSA).
- A higher AHI was observed in male adolescents compared to younger boys.
- Age-related increases in AHI are more pronounced in boys, with gender influencing the impact of age and obesity on OSA severity.
Background:
Age and gender disparities in polysomnographic findings in children are not well understood.
Objective:
This study determined age and gender-related characteristics in pediatric obstructive sleep apnea (OSA).
Method:
Retrospectively, data were collected. We analyzed polysomnographic data in the following age groups: 3-6 years (n = 681), 6-9 years (n = 553), 9-12 years (n = 297), 12-15 years (n = 200), and 15-18 years (n = 111).
Results:
A total of 1842 children were included (mean age: 8.0 years; boys: 67%; obesity: 21%). The apnea-hypopnea index (AHI) gradually increased with age (3-6, 6-9, 9-12, 12-15, and 15-18 years groups: 6.2, 5.9, 6.5, 8.1, and 9.9 event/h, respectively; p trend = 0.002). In all age groups, boys had a higher AHI than girls (7.8 vs. 4.1 events/h, p < 0.001). Children with obesity had a higher AHI than those without (12.9 vs. 4.9 events/h, p < 0.001). The mean AHI in the boys increased with age (3-6 to 15-18 years groups: 7.0-13.6 events/h, respectively; p trend < 0.001), whereas the mean AHI in the girls was not significantly different between ages (p trend = 0.492). In moderation analyses, gender was a moderator in the association between obesity and AHI, and the association between age and AHI during 12-15 and 15-18 years of ages.
Conclusion:
Male gender and obesity increase risk of OSA. Regarding age disparities, this study discovered a higher AHI in male adolescents than in young boys.
