Abstract: The study aims to investigate the prevalence, and social and health correlates of insomnia symptoms in a national population sample in South Africa. Data were analysed from the crosssectional 'South African National Health and Nutrition Examination Survey (SANHANES-1)' 2012, using a sample of 15,133 individuals (mean age = 36.9, SD = 16.5). Measures included information on insomnia, sociodemographics, health status, health risk behaviour, and mental health. Results indicate that the overall prevalence of insomnia symptoms was 7.1%, with 3.5% among 15- to 24-year-olds and 20.5% among 65 years and older participants. In the adjusted logistic regression analysis, poorer health status (self-rated health, functional disability and cognitive impairment), having bodily pain, having experienced three or more traumatic events, and having psychological distress and partial Posttraumatic Stress Disorder were positively associated with insomnia. A significant proportion of South Africans have insomnia symptoms and several risk factors were identified that can help in guiding interventions
