Sleep patterns among Aboriginal and Torres Strait Islander Peoples and non-Indigenous Australians: A South Australian descriptive exploratory study

Aim: Irregularities with sleep patterns and behaviours are commonly observed in Australia, but there is lack of information regarding sleep patterns among Aboriginal or Torres Strait Islander adults. This study explores sleep patterns in Aboriginal or Torres Strait Islander adults, comparing it with non-Indigenous Australian adults in addition to investigating any potential effects on daytime behaviour.

Methods: A total of 730 Aboriginal and Torres Strait Islander Peoples aged 18 years and above were included in the study. The participants completed a self-reported questionnaire on various aspects of sleep, such as difficulty falling asleep, waking up during the night, feeling well-rested upon waking, snoring loudly, gasping/choking during sleep, use of prescription medication and experiencing fatigue or sleepiness during the day. Additionally, the participants were interviewed using the 'Top End Sleepiness Scale' to report increased sleepiness during daily activities. The responses were compared with those of non-Indigenous Australians in the 2016 Sleep Health Foundation national survey, using questions that measures similar variables.

Results: Aboriginal and Torres Strait Islander Peoples experienced higher rates of sleep disturbances, including difficulty in falling asleep and waking in the night. Snoring and breathing pauses during sleep were more common in middle-aged men, and sleeping difficulties and daytime symptoms related to insufficient or unrefreshing sleep were more common in women. Sleep issues increased with age among adult Australians but were more common in the age group of 25-34 years for Aboriginal and Torres Strait Islander Peoples.

Conclusion: The data suggest that Aboriginal and Torres Strait Islander adults report irregularities in sleep patterns. Early interventions and management of sleep habits could potentially have benefits for overall physical and mental health.
