London, March 2, 2017: Do you have a desk-bound job? Beware, you may be at a heightened risk of developing cardiovascular diseases by 0.2 per cent and an increase in waist circumference by two cm, for every additional hour of sitting on top of five hours, researchers warned.

The findings showed that those who had desk jobs had a bigger waist circumference — 97 cm compared to 94 cm in people without desk jobs. They also had approximately one body mass index (BMI) unit difference.

Further, they had a higher risk of cardiovascular disease — 2.2 per cent compared to 1.6 per cent in people without desk jobs, over ten years.

In addition, each extra hour of sitting from five hours a day, increased the levels of bad cholesterol (LDL) and decreased good cholesterol (HDL).

“Longer time spent in sedentary posture is significantly associated with larger waist circumference, higher triglycerides (fat in the blood) and lower HDL cholesterol, all adding up to worse risk of heart disease,” said William Tigbe from University of Warwick in Britain.

In contrast, walking more than 15,000 steps per day, which is equivalent to walking seven to eight miles, or spending seven hours per day upright, may be associated with zero risk factors, Tigbe added, in the paper published in the International Journal of Obesity.

Although the study could be used as the basis of new public health targets for sitting, lying, standing and stepping to avoid metabolic risks, it would be very challenging to achieve unless incorporated into people’s occupations.

“Our evolution, to become the human species, did not equip us well to spending all day sitting down. We probably adapted to be healthiest spending seven to eight hours every day on our feet, as hunters or gatherers,” said Mike Lean Professor at the University of Glasgow. (IANS)

Obesity Alone Does not Increase Death Risk: Study

Earlier, a study, published in The Lancet Diabetes and Endocrinology journal, found that women with metabolically healthy obesity were at 39 per cent higher risk of cardiovascular disease

Patients who have metabolically healthy obesity but are free from other metabolic risk factors do not have an increased rate of mortality, a new study has found.

Metabolically healthy obesity is a debatable medical condition characterized by obesity which does not produce metabolic complications.

The study, published in the journal Clinical Obesity, showed that unlike dyslipidemia, hypertension and diabetes — each one of which is related to high mortality risk — obesity alone does not pose any threat to life.

“We are showing that individuals with metabolically healthy obesity are actually not at an elevated mortality rate,” said lead author Jennifer Kuk, Associate Professor at the York University in Canada.

“We found that a person of normal weight with no other metabolic risk factors is just as likely to die as the person with obesity and no other risk factors,” Kuk added.

For the study, the research team followed 54,089 men and women from five cohort studies who were categorized as having obesity alone or clustered with a metabolic factor, or elevated glucose, blood pressure or lipids alone or clustered with obesity or another metabolic factor.

The researchers looked at how many people within each group died as compared to those within the normal weight population with no metabolic risk factors.

They found that one out of 20 individuals with obesity had no other metabolic abnormalities.

“This is in contrast with most of the literature and we think this is because most studies have defined metabolic healthy obesity as having up to one metabolic risk factor,” said Kuk.

“This is clearly problematic, as hypertension alone increases your mortality risk and past literature would have called these patients with obesity and hypertension, ‘healthy’. This is likely why most studies have reported that ‘healthy’ obesity is still related with higher mortality risk,” Kuk noted.
