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.
