Insights
Asthmatic children have a high risk of obstructive sleep apnea (OSA). Symptoms like snoring indicate a need for OSA screening in children with asthma.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Respiratory Disorders
Background:
- Obstructive sleep apnea (OSA) is a prevalent respiratory condition in children.
- Asthma is a common chronic condition in childhood.
- The co-occurrence and characteristics of OSA in asthmatic children require further investigation.
Purpose of the Study:
- To characterize obstructive sleep apnea (OSA) in pediatric asthma patients.
- To identify symptoms indicative of a high risk for OSA in asthmatic children.
Main Methods:
- Prospective and descriptive study design.
- Inclusion of asthmatic children aged preschool and school years.
- Data collection via medical history, clinical examination, spirometry, exhaled nitric oxide (NO), and respiratory polygraphy.
Main Results:
- A high prevalence of OSA (65.9%) was observed in the studied asthmatic children.
- Severe OSA was more common in children with moderate asthma compared to mild or intermittent asthma.
- Snoring, sleep disturbance, and nocturnal sweats were significantly more frequent in asthmatic children with OSA. Allergic rhinitis and snoring were significant predictors of OSA.
Conclusions:
- Children with asthma are at an increased risk for obstructive sleep apnea (OSA).
- Asthmatic children presenting with symptoms such as snoring or nocturnal awakenings warrant screening for OSA.
- Early identification and management of OSA in asthmatic children can improve respiratory health outcomes.
Background And Objective:
The obstructive sleep apnea (OSA) is a common respiratory disorder in children, especially those at preschool and school ages. This study aimed to describe the characteristics of asthmatic children with OSA and the symptoms for a high risk of OSA.
Subjects And Methods:
It was a prospective and descriptive study. The data of asthmatic children including medical history, clinical examination, blood tests, spirometry, exhaled nitric oxide (NO), and respiratory polygraphy were registered for analyses.
Results:
Eighty-five asthmatic children with a mean age of 9.5 ± 2.1 years were included. The prevalence of OSA was 65.9% (56/85) in study subjects. The prevalence of severe OSA in children with moderate asthma was significantly higher than intermittent and mild asthma. The percentage of asthmatic children with OSA who had snoring, sleep disturbance, and nocturnal sweats was significantly higher than that of asthmatic children without OSA (48.2% vs 17.2%, 71.4% vs 27.5%, and 55.1% vs 31.0%, respectively). The presence of allergic rhinitis and snoring was associated significantly with a high probability for the presence of OSA.
Conclusion:
Children with asthma have a risk of OSA. Asthmatic children with suggested symptoms such as snoring or waking up at night should be screened for OSA.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
