Insights
Daily snoring in children is a significant indicator for obstructive sleep apnoea syndrome (OSAS). This symptom aids in identifying children who require further sleep study evaluation.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Medicine
Background:
- Obstructive sleep apnoea syndrome (OSAS) is a common condition in children.
- Accurate identification of OSAS is crucial for timely intervention.
Purpose of the Study:
- To determine the key clinical factors for identifying OSAS in pediatric patients.
- To establish the predictive value of specific symptoms for OSAS.
Main Methods:
- Prospective study conducted at a regional hospital's pediatric sleep clinic.
- Utilized standard questionnaires and overnight polysomnography.
- Logistic regression analysis applied to identify risk factors.
Main Results:
- Out of 62 children, 22 were diagnosed with OSAS.
- 'Snoring every night' emerged as the most significant predictor (p<0.0001).
- This symptom demonstrated high sensitivity (91%) and specificity (75%) for OSAS.
Conclusions:
- Frequent snoring is a critical clinical factor for identifying childhood OSAS.
- Children reporting nightly snoring warrant priority for polysomnography.
- This finding can streamline diagnostic pathways for pediatric OSAS.
Objective:
To identify the clinical factor(s) that identify obstructive sleep apnoea syndrome (OSAS) in children.
Methods:
A prospective study of children referred to the sleep clinic of the paediatric department was conducted in a public non-teaching regional hospital in Hong Kong. A standard questionnaire was administered and overnight sleep polysomnography was performed in a consecutive series of patients. Logistic regression analysis was performed to obtain significant risk factors for prediction of OSAS in this series of patients.
Results:
Sixty-two children were enrolled into the study and 22 were diagnosed to have OSAS. Logistic regression analysis showed that, among all the answers, 'snoring every night' is the single most significant risk factor (p<0.0001) to predict OSAS. 'Snoring every night' has a sensitivity of 91% and specificity of 75% for OSAS patients. It also has a positive predictive value of 67% and negative predictive value of 94%.
Conclusion:
Snoring every night is an important risk factor in identifying OSAS in children. Priority for an overnight sleep polysomnogram should be given to those with this symptom.
