Systematic Review Flags 12.8-20.4% Preschool Sleep Apnea Prevalence but Limited Polysomnography Data
Childhood obstructive sleep apnea prevalence estimates vary widely due to inconsistent diagnostics, with obesity and adenotonsillar enlargement as key modifiable drivers. Limited polysomnography data and absent long-term outcome trials leave treatment thresholds imprecise. Rigorous prospective studies are needed to link objective indices to developmental and metabolic endpoints.
Next steps require large prospective cohorts linking polysomnography indices to neurodevelopmental trajectories at five-year follow-up, plus RCTs testing adenotonsillectomy versus watchful waiting stratified by obesity status. Such designs would clarify whether early intervention alters cardiometabolic or cognitive outcomes beyond symptom relief.
Pediatric Sleep Medicine Society: By 2028 at least one multicenter RCT will report five-year neurocognitive outcomes comparing early adenotonsillectomy to monitoring in obese versus non-obese children with AHI 5-10.
