Sedentary behaviour in obese adults linked to serious health risks

13 January 2016

A new study has demonstrated the potentially serious health risks associated with sedentary behaviour among obese adults.

The University of Pittsburgh Graduate School of Public Health research followed 927 patients undergoing weight loss surgery at one of ten US hospitals, following them for a one-week period before surgery to measure their activity levels.

It was shown that for every hour per day participants spent in sedentary bouts of at least ten minutes, their odds of having diabetes increased by 15 per cent, with their metabolic syndrome risk rising by 12 per cent and blood pressure up by 14 per cent.

These trends remained prevalent even after adjusting for potential confounding factors such as the amount of exercise they undertook, indicating that taking part in physical activity does not mitigate the harmful impact of excessive sitting.

Lead author Dr Wendy King, associate professor for the department of epidemiology at the University of Pittsburgh Graduate School of Public Health, said: "These findings indicate the importance of investigating sedentary behaviour as a distinct health risk behaviour, not simply lack of moderate to vigorous-intensity physical activity, among adults with severe obesity."
