Bridging the gap in sleep health: a study of obstructive sleep apnoea (OSA) in First Nations Australians residing in South East Queensland.

Obstructive sleep apnoea (OSA) is common in Australia but underexamined among First Nations peoples. We conducted a retrospective cross-sectional analysis of 1563 adult sleep studies in South East Queensland (2022-2023). Thirty-eight participants (2.4%) identified as First Nations, of whom 74% had OSA. Comorbidities were more frequent among the First Nations cohort, though small sample size limited certainty. These findings reveal both under-identification of First Nations status and a substantial OSA burden, emphasising the need for culturally informed, community-led approaches to OSA care in Queensland.
