Sedentary behaviour is associated with poor cardiovascular health and diabetes in adults with severe obesity, independent of how much exercise they perform, the study said.

According to the researchers, the findings could be used to design and test programmes for adults with severe obesity that emphasise reducing time spent sitting, rather than immediately working toward increased moderate- to vigorous-intensity physical activity or exercise, such as brisk walking.

For the study, the researcher followed 927 patients participating in a prospective study of patients undergoing weight-loss surgery at one of 10 different hospitals across the US.

For every hour per day participants spent in sedentary bouts of at least 10 minutes, their odds of having diabetes increased by 15 percent, metabolic syndrome by 12 percent and elevated blood pressure by 14 percent.

The study was published online in the journal Preventive Medicine.
