Sociodemographic and health correlates of sleep problems and duration in older adults in South Africa
Abstract
who participated in the Study of Global Ageing and Adult Health (SAGE) in 2008.
Methods. In 2008 I conducted a national population-based cross-sectional study with a sample of 3 840 South African individuals aged .50 years. A questionnaire was used to survey sociodemographic characteristics and health variables, and anthropometric and blood pressure measurements were recorded.
Results. Of the participants, 9.1% reported having a sleeping problem at the time of the study. The average number of self-reported hours of sleep was 8.6 (SD }2.1), with 11.6%, 45.1%, 20.0%, and 23.5% reporting .6, 7 - 8, 9, and .10 h, respectively. In multivariable analysis, depression, cognitive impairment, lack of social cohesion, and moderate or severe activity limitations were associated with having a current sleeping problem. In terms of sociodemographic and health variables, a short sleep duration was associated with: white, Indian/Asian or coloured ethnicity; daily tobacco use; and moderate and severe activity limitations. In participants aged 60 - 79 years, lower wealth, hypertension, risky drinking and lower health-related quality of life were associated with a long sleeping duration.
Conclusion. This study robustly characterised the prevalence of sleeping problems and specific associated risk factors in a large sample in South Africa. This can help to direct future healthcare efforts.
