Little is known about physical activity (PA) levels and correlates in adults from rural settings in South Africa, where a rapid increase in the number of older people and marked disparities in wealth are evident, particularly between those living in rural and urban areas. This paper describes levels of self-reported PA in rural South African men and women and examines factors associated with meeting PA guidelines. Global Physical Activity Questionnaire (GPAQ) data from the Health and Aging in Africa: Longitudinal studies of INDEPTH communities (HAALSI) survey of 5059 adults aged over 40 years were assessed.

Introduction: Research has not been conducted on physical activity in early child education and care (ECEC) settings in low-income, rural communities in South Africa. This study aimed to describe the physical activity environment of these settings and identify child and contextual factors associated with physical activity in these settings. By understanding physical activity in this environment, it will be possible to identify context-specific opportunities, including with teachers, to overcome potential challenges and maximise physical activity in a low- and middle-income country setting.

Background: Walking is recognized as an easily accessible mode of physical activity and is therefore supported as a strategy to promote health and well-being. To complement walking, pedometers have been identified as a useful tool for monitoring ambulatory physical activity, typically measuring total steps/day. There is, however, little information concerning dose-response for health outcomes in relation to intensity or duration of sustained steps.
