Insights
Children diagnosed with obstructive sleep apnoea (OSA) experience significant health issues years before and after diagnosis. This condition is linked to increased morbidity and a higher mortality rate compared to their peers.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Epidemiology
Background:
- Obstructive sleep apnoea (OSA) in children is not well understood regarding diagnostic patterns.
- There is a need to evaluate the morbidity and mortality associated with childhood OSA.
Purpose of the Study:
- To investigate the diagnostic patterns of obstructive sleep apnoea (OSA) in children.
- To evaluate the association of childhood OSA with morbidity and mortality.
Main Methods:
- A cohort of 2998 children (aged 0-19) diagnosed with OSA was identified from the Danish National Patient Registry.
- 11,974 matched controls were selected based on age, sex, and socioeconomic status.
Main Results:
- Patients with OSA exhibited increased morbidity in the 3 years preceding diagnosis, including infections, endocrine, nervous, eye, ENT, respiratory, gastrointestinal, skin, and congenital conditions.
- Post-diagnosis, OSA was linked to higher incidences of endocrine, nervous, ENT, respiratory, skin, musculoskeletal, congenital diseases, and abnormal clinical findings.
- The 5-year mortality rate was significantly higher in children with OSA (70 per 10,000) compared to controls (11 per 10,000), with a hazard ratio of 6.58.
Conclusions:
- Childhood obstructive sleep apnoea (OSA) is associated with substantial morbidity that manifests years before and persists after diagnosis.
- OSA in children significantly increases the risk of mortality.
Background:
Little is known about the diagnostic patterns of obstructive sleep apnoea (OSA) in children. A study was undertaken to evaluate morbidity and mortality in childhood OSA.
Methods:
2998 patients aged 0-19 years with a diagnosis of OSA were identified from the Danish National Patient Registry. For each patient we randomly selected four citizens matched for age, sex and socioeconomic status, thus providing 11 974 controls.
Results:
Patients with OSA had greater morbidity at least 3 years before their diagnosis. The most common contacts with the health system arose from infections (OR 1.19, 95% CI 1.01 to 1.40); endocrine, nutritional and metabolic diseases (OR 1.30, 95% CI 0.94 to 1.80); nervous conditions (OR 2.12, 95% CI 1.65 to 2.73); eye conditions (OR 1.43, 95% CI 1.07 to 1.90); ear, nose and throat (ENT) diseases (OR 1.61, 95% CI 1.33 to 1.94); respiratory system diseases (OR 1.78, 95% CI 1.60 to 1.98); gastrointestinal diseases (OR 1.34, 95% CI 1.09 to 1.66); skin conditions (OR 1.32, 95% CI 1.02 to 1.71); congenital malformations (OR 1.56, 95% CI 1.31 to 1.85); abnormal clinical or laboratory findings (OR 1.21, 95% CI 1.06 to 1.39); and other factors influencing health status (OR 1.29, 95% CI 1.16 to 1.43). After diagnosis, OSA was associated with incidences of endocrine, nutritional and metabolic diseases (OR 1.78, 95% CI 1.29 to 2.45), nervous conditions (OR 3.16, 95% CI 2.58 to 3.89), ENT diseases (OR 1.45, 95% CI 1.14 to 1.84), respiratory system diseases (OR 1.94, 95% CI 1.70 to 2.22), skin conditions (OR 1.42, 95% CI 1.06 to 1.89), musculoskeletal diseases (OR 1.29, 95% CI 1.01 to 1.64), congenital malformations (OR 1.83, 95% CI 1.51 to 2.22), abnormal clinical or laboratory findings (OR 1.16, 95% CI 1.06 to 1.27) and other factors influencing health status (OR 1.35, 95% CI 1.20 to 1.51). The 5-year death rate was 70 per 10 000 for patients and 11 per 10 000 for controls. The HR for cases compared with controls was 6.58 (95% CI 3.39 to 12.79; p<0.001).
Conclusions:
Children with OSA have significant morbidities several years before and after their diagnosis.
