GPAtlas🧭 When to suspect
Obstructive sleep apnoea (OSA) in children sits on a spectrum of sleep-disordered breathing that runs from harmless primary (simple) snoring – affecting roughly 12–15% of children – through to true OSA, in which repeated upper-airway collapse during sleep causes apnoeas and fragmented, non-restorative sleep. OSA affects about 1–2% of children and, unlike in adults, occurs equally in boys and girls.
Suspect OSA in any child who snores regularly when otherwise well, particularly alongside witnessed pauses, gasping or choking, restless sleep, or daytime behavioural and concentration problems. There are two characteristic peaks: a common preschool peak (roughly 2–6 years) driven by adenotonsillar hypertrophy, and a second peak in older children and adolescents related to obesity.
The key primary-care skills are to distinguish simple snoring from OSA, to recognise the daytime behavioural impact, and to refer the right child by the right route – ENT for uncomplicated adenotonsillar disease, paediatrics for the child with comorbidities.
| Feature | Primary (simple) snoring | Obstructive sleep apnoea |
|---|---|---|
| Snoring pattern | Habitual snoring, but no witnessed pauses | Loud snoring with witnessed pauses, gasps or snorts |
| Oxygen desaturation | None | Episodic dips in oxygen during sleep |
| Daytime effects | None of significance | Behavioural problems, poor concentration, ± sleepiness |
| Approximate prevalence | ~12–15% of children | ~1–2% of children |
| Action | Reassure and safety-net | Refer for specialist assessment |

🧠 Clinical pearl In children, OSA more often shows itself as daytime hyperactivity, inattention and behavioural problems – mimicking attention deficit hyperactivity disorder (ADHD) – than as the classic adult pattern of daytime sleepiness. Always ask about sleep and snoring before settling on a behavioural label, and remember that, in children, obstructive events cluster in rapid eye movement (REM) sleep rather than across all sleep stages. |
