The August 2011 issue of the American Journal of Preventive Medicine contains a number of articles focusing on the health impact of sedentary behaviour. In the press release announcing this issue they explain that
“Epidemiologic and physiologic research on sedentary behavior suggests that there are novel health consequences of prolonged sitting time, which appear to be independent of those attributable to lack of leisure-time physical activity,” commented Neville Owen, PhD, Head of Behavioural Epidemiology at the Baker IDI Heart and Diabetes Institute, Melbourne, Australia. “However, behavioral research that could lead to effective interventions for influencing sedentary behaviors is less developed, especially so for adults. The purpose of this theme issue of the American Journal of Preventive Medicine is to propose a set of perspectives on ‘too much sitting’ that can guide future research. As the theme papers demonstrate, recent epidemiologic evidence (supported by physiologic studies) is consistent in identifying sedentary behavior as a distinct health risk. However, to build evidence-based approaches for addressing sedentary behavior and health, there is the need for research to develop new measurement methods, to understand the personal, social, and environmental factors that influence sedentary behaviors, and to develop and test the relevant interventions.”
