Insights
Childhood asthma is significantly linked to a higher risk of obstructive sleep apnea (OSA). This association suggests sleep disorders may worsen asthma, warranting integrated screening and management.
Area of Science:
- Pediatrics
- Pulmonology
- Sleep Medicine
Background:
- Asthma is a common chronic respiratory disease in children.
- Obstructive sleep apnea (OSA) is a prevalent sleep disorder in pediatric populations.
- The relationship between childhood asthma and OSA requires systematic evaluation.
Purpose of the Study:
- To systematically evaluate the correlation between childhood asthma and obstructive sleep apnea (OSA).
Main Methods:
- A comprehensive literature search was conducted across multiple databases up to March 2025.
- Keywords included "asthma," "obstructive sleep apnea," and "child*."
- Included were observational studies with children diagnosed with OSA and asthma using established criteria.
Main Results:
- Eleven studies from the US, Europe, and Asia were included.
- A pooled odds ratio (OR) of 1.66 (95% CI, 1.21-2.26) indicated a significant association between childhood asthma and OSA.
- The association was strongest in America and Asia, with significant findings in cohort and cross-sectional studies.
Conclusions:
- Childhood asthma is significantly associated with an increased risk of OSA.
- Sleep disorders may exacerbate the asthma condition.
- Integrated screening and management strategies are recommended, especially in high-risk regions like America and Asia.
Abstract:
Background: The study was to systematically evaluate the correlation between childhood asthma and obstructive sleep apnea (OSA). Methods: Several medical literature data bases were searched for studies published up to March 2025, by using the keywords "asthma" and "obstructive sleep apnea" and "child*." We included observational studies, children with OSA diagnosed via polysomnography, clinical criteria, or validated tools; and asthma confirmed by physician diagnosis, medication use, or validated questionnaires and international code. Results: Eleven studies were included that covered populations in the United States, Europe, and Asia. The pooled odds ratio (OR) for the association between childhood asthma and OSA was 1.66 (95% confidence interval [CI], 1.21-2.26; p < 0.001). Subgroup analysis by study design showed significant associations in cohort (OR 2.00 [95% CI, 1.35-2.96]) and cross-sectional (OR 1.55 [95% CI, 0.69-3.44]) but not in case-control studies (OR 0.85 [95% CI, 0.32-2.28]). Geographically, the association was strongest in America (OR 1.99 [95% CI, 1.35-2.96]) and Asia (OR 1.64 [95% CI, 1.19-2.25]), with a nonsignificant trend in Europe (OR 0.91 [95% CI, 0.34-2.42]). Sensitivity analyses directionally consistent with the results, and Egger's test (p = .587) indicated no significant publication bias. Conclusion: Childhood asthma is significantly associated with an increased risk of OSA, with sleep disorders likely exacerbating this relationship. Integrated screening and management strategies are warranted, particularly in high-risk regions such as America and Asia.

Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
