obesity paradox

UK study debunks 'obesity paradox' theory

A study by led by researchers at the University of Glasgow has debunk the notion that people who are overweight or obese are not at increased risk of heart disease, (obesity paradox). The study, which included nearly 300,000 people, shows that the risk of heart attacks, strokes and high blood pressure, increases as BMI increases beyond a BMI22-23. Furthermore, the risk also increases steadily the more fat a person carries around their waist.

Obesity paradox not found when measuring new cases of CVD

A study by NYU College of Global Public Health and the University of Michigan has reported that the so-called ‘obesity paradox’ is not present among people with new cases of cardiovascular disease (CVD). Although obesity is a well-known risk factor for getting cardiovascular disease, a controversial body of research suggests that obesity may actually be associated with improved survival among people who have cardiovascular disease.

Overweight and obese have higher risk of dying early

Being overweight or obese is associated with a higher risk of dying prematurely than being normal weight—and the risk increases with additional pounds, according to a large international collaborative study led by researchers at the Harvard TH Chan School of Public Health and the University of Cambridge, UK. The findings contradict recent reports that suggest a survival advantage to being overweight - the so-called ‘obesity paradox’.

Study finds obesity paradox is a product of biases

Demographers Samuel Preston of the University of Pennsylvania and Andrew Stokes of Boston University have found that studies reporting that obese or overweight people with cardiovascular disease are outliving their normal weight counterparts – the so-called obesity paradox – are a product of biases involving reverse causation and confounding by smoking.

Overweight patients live longer than less heavy T2DM patients

Patients with type 2 diabetes who are overweight but not obese live longer than those who are underweight or normal-weight, according to a study is published in Annals of Internal Medicine. The adds further to the co-called ‘obesity paradox’ debate, which some researchers believe that overweight patients with cardiovascular disease live longer than normal-weight patients with cardiovascular disease.

Obese heart failure patients have higher survival rates

Patients who were obese before developing heart failure lived longer than normal weight patients with the same condition, according to a study in the Journal of the American College of Cardiology that examined the ‘obesity paradox’ by following obese and non-obese heart failure patients for more than a decade.

No evidence of obesity paradox in stroke patients

There is no evidence of an ‘obesity paradox’ in patients with stroke, according to researchers from the Danish Cancer Society Research Center, Copenhagen, Denmark. Although obesity often is associated with increased health related complications and death, some studies have suggested an obesity paradox that may cause some to question striving for a normal weight.

Study claims obesity paradox is a myth

The obesity paradox is a myth as research suggests that there is no healthy pattern of increased weight. Investigators found that compared with metabolically healthy normal-weight individuals, obese persons are at increased risk for adverse long-term outcomes even in the absence of metabolic abnormalities, which indicates that there is no healthy pattern of increased weight.

Obesity paradox studies are flawed claim researchers

Previous studies that claim the obesity epidemic is overhyped are flawed, according to new research published in the American Journal of Epidemiology.

"This study should put to rest the notion that it's possible to 'age out' of obesity risk, and provides a powerful counterfactual against those who say concern over obesity is overhyped," said Dr Bruce Link, professor of Epidemiology and Sociomedical Sciences, Mailman School, Columbia University.
