Insights
Clinical symptoms can help identify obstructive sleep apnea (OSA) and its severity in children. Specific symptoms are also predictive in obese children, though they differ from non-obese children.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Clinical Diagnostics
Background:
- Obstructive sleep apnea (OSA) is a common condition in children.
- Accurate diagnosis and severity assessment are crucial for effective management.
- Identifying reliable clinical predictors can aid in early detection and intervention.
Purpose of the Study:
- To evaluate the utility of clinical symptoms in predicting the presence and severity of OSA in pediatric patients.
- To compare the predictive value of symptoms between obese and non-obese children.
Main Methods:
- A questionnaire assessing 56 clinical symptoms was administered to parents of children undergoing polysomnography (PSG).
- Responses were analyzed to compare symptom patterns between children with varying OSA severities (mild, moderate, severe, none) and between obese and non-obese groups.
- Statistical analysis identified symptoms predictive of OSA presence and severity.
Main Results:
- 235 children (mean age 5.76 years) were included, with 31.5% mild OSA, 13.19% moderate OSA, 24.7% severe OSA, and 30.64% no OSA.
- Obesity was present in 37% of the cohort.
- Specific sets of symptoms predicted mild-to-severe OSA in both non-obese (8 symptoms) and obese (6 symptoms) children. Different symptom profiles predicted severe OSA in non-obese (16 symptoms) and obese (9 symptoms) children.
Conclusions:
- Clinical symptoms are valuable tools for predicting the presence and severity of OSA in children.
- Symptoms can also predict OSA in obese children, but the specific predictive symptoms differ compared to non-obese children.
- This highlights the importance of considering obesity when interpreting clinical symptoms for OSA diagnosis in pediatric populations.
Objective:
To determine if a set of clinical symptoms can help in determining the presence and severity of OSA.
Setting:
Tertiary urban pediatric hospital.
Methods:
Parents of children undergoing an overnight PSG answered a 56 item questionnaire based on their child's symptoms. The responses to the questionnaire were compared between patients with different severities of OSA (s determined by PSG) and those without OSA. Responses to questionnaire were also analyzed between obese and non-obese patients.
Results:
235 children were included (140 male and 95 female) with a mean age of 5.76 ± 2.78 years. The mean Apnea Hypopnea Index (AHI) was 7.78 ± 14.50 events/hour (range 0-110 events/h). 74 (31.5%) children had mild-OSA (AHI between 1 and 4.99 events/h), 31 (13.19%) had moderate-OSA (AHI between 5 and 9.99 events/h), 58 (24.7%) had severe-OSA (AHI≥10events/h) and the remaining 72 (30.64%) had No-OSA (AHI≤1event/h). 87 (37%) patients were obese. Eight clinical symptoms in non-obese and six clinical symptoms in obese patients predicted the mild to severe OSA. Sixteen symptoms in non-obese patients and nine symptoms in obese patients predicted the presence of severe OSA in these patients.
Conclusion:
Clinical symptoms reported in this study are useful to predict the presence of and the severity of OSA in children. Clinical symptoms can also predict the presence and severity of OSA in children who are obese, however, the symptoms required to make the prediction are different in obese children.
