O021 Indigenous Sleep Health Survey

BACKGROUND: There is increasing evidence of ongoing inequity in the provision of sleep healthcare for Indigenous Australians. This cross-sectional review aims to capture the prevalence self-reported symptoms of poor sleep and correlating factors influencing this from an Indigenous perspective. METHODS: This survey data was collected as part of the Indigenous Human Papilloma and Oropharyngeal Squamous Cell Carcinoma study with demographic data and sleep indices collected at the 24 month follow up time point. Participants were >18 years of age, identified as Aboriginal and/or Torres Strait Islanders, and were recruited from Aboriginal Community Controlled Health Organisations in South Australia from February 2018 to January 2019. PROGRESS TO DATE: 729 responses were collected from participants aged 18 to 79, with 227 (31.1%) males and 502 (68.9%) females . Most participants lived in rural locations (62.9% [457/727]). 21.9% (75/343) participants reported witnessed loud snoring three or more times/week, with 16.1% (55/342) reporting witnessed apnoea once or more per week. Top End Sleepiness Score of ≥8 which has been associated with moderate to severe obstructive sleep apnoea was reported in 6.6% (48) of participants. Further data analysis is underway. INTENDED OUTCOME AND IMPACT: This survey of Indigenous Australians included demographic details, OSA-50 scores, TESS scores, subjective assessment of factors determining sleep quality, as well as social determinants of sleep health. Correlating this data will provide a fuller understanding of the current self-perception of sleep and factors affecting it in this population.
