The impact of childhood obstructive sleep apnea on speech and oral language development: a systematic review

Purpose: The purpose of this systematic review was to review and synthesize the current evidence on speech and language outcomes of children with Obstructive Sleep Apnea (OSA), or more broadly sleep disordered breathing. Method: A comprehensive literature search was conducted across 5 databases. Studies were selected based on the following criteria: 1) peer-reviewed research published between 2000 and 2020, 2) available in English or accessible non-English data, 3) children aged 2-13 years diagnosed with Sleep Disordered Breathing (SDB) or OSA, and 4) speech and language outcomes examined within research. Results: Studies were appraised using PEDro-P and the overall certainty of evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Six studies met the current review selection criteria: one paper examined speech outcomes and the remaining five examined receptive and expressive language outcomes. The overall quality of the body of evidence was rated as very low, with methodological weaknesses present in study designs and sample sizes. Conclusion: Speech and language difficulties are common in children with OSA/SDB, in addition to neurocognitive and/or neurobehavioral issues. Further investigation of specific speech and language skills, which are compromised in this population, is needed to guide clinical practice and decision making, with particular involvement from speech-language pathologists.
