Majority of people -- including health professionals -- struggle to identify obesity
2014-11-11
(Press-News.org) The majority of people - including healthcare professionals - are unable to visually identify whether a person is a healthy weight, overweight or obese according to research by psychologists at the University of Liverpool.
Researchers from the University's Institute of Psychology, Health and Society asked participants to look at photographs of male models and categorise whether they were a healthy weight, overweight or obese according to World Health Organisation (WHO) Body Mass Index (BMI) guidelines.
They found that the majority of participants were unable to correctly identify whether they were a healthy weight, overweight or obese person. Participants instead underestimated weight, often believing that overweight men were a healthy weight.
In a related study of healthcare professionals, the researchers also found that GPs (General Practitioners) and trainee GPs were unable to visually identify if a person was overweight or obese.
The researchers also examined whether increased exposure to overweight and obese people affected a person's ability to estimate the weight of a person. Their findings suggested that exposure to heavier body weights may influence what people see as a normal and healthy weight and causes people to underestimate a person's weight.
Psychologist, Dr Eric Robinson, who conducted the research, said: "We wanted to find out if people can identify a healthy, overweight or obese person just by looking at them.
"Primarily we found that people were often very inaccurate and this included trainee doctors and qualified doctors too. Moreover, we found that participants systematically underestimated when a person was overweight or obese."
"Our study of GPs also found a tendency to underestimate weight which has important implications as it means that overweight and obese patients could end up not being offered weight management support or advice.
Recent studies have found that parents underestimate their overweight or obese child's weight and this could also act as a barrier to intervention.
Dr Robinson added: "Over the last 30 years we have seen changes to population body weight, so examining how this has affected how we view our own and other people's body sizes is an interesting area of research."
The UK has the highest level of obesity in Western Europe. Obesity levels in the UK have more than trebled in the last 30 years and, on current estimates, more than half the population could be obese by 2050. More than half of the adult population in the European Union are overweight or obese.

The research was presented at the UK Congress of Obesity and the study of GPs is published in the British Journal of General Practice.

CHAMPAIGN, Ill. -- Tiny, thin microtubes could provide a scaffold for neuron cultures to grow so that researchers can study neural networks, their growth and repair, yielding insights into treatment for degenerative neurological conditions or restoring nerve connections after injury.
Researchers at the University of Illinois at Urbana-Champaign and the University of Wisconsin-Madison created the microtube platform to study neuron growth. They posit that the microtubes could one day be implanted like stents to promote neuron regrowth at injury sites or to treat disease.

WEST LAFAYETTE, Ind. - Crop producers and scientists hold deeply different views on climate change and its possible causes, a study by Purdue and Iowa State universities shows.
Associate professor of natural resource social science Linda Prokopy and fellow researchers surveyed 6,795 people in the agricultural sector in 2011-2012 to determine their beliefs about climate change and whether variation in the climate is triggered by human activities, natural causes or an equal combination of both.
More than 90 percent of the scientists and climatologists surveyed said they ...

Located hundreds of miles inland from the nearest ocean, the Midwest is unaffected by North Atlantic hurricanes.
Or is it?
With the Nov. 30 end of the 2014 hurricane season just weeks away, a University of Iowa researcher and his colleagues have found that North Atlantic tropical cyclones in fact have a significant effect on the Midwest. Their research appears in the Bulletin of the American Meteorological Society.

COLUMBIA, Mo. - Glycogen storage disorders, which affect the body's ability to process sugar and store energy, are rare metabolic conditions that frequently manifest in the first years of life. Often accompanied by liver and muscle disease, this inability to process and store glucose can have many different causes, and can be difficult to diagnose. Now, researchers at the University of Missouri who have studied enzymes involved in metabolism of bacteria and other organisms have catalogued the effects of abnormal enzymes responsible for one type of this disorder in humans. ...

What if you researched your family's genealogy, and a mysterious stranger turned out to be an ancestor?
That's the surprising feeling had by a team of scientists who peered back into Europe's murky prehistoric past thousands of years ago. With sophisticated genetic tools, supercomputing simulations and modeling, they traced the origins of modern Europeans to three distinct populations.
The international research team published their September 2014 results in the journal Nature.
XSEDE, the Extreme Science and Engineering Discovery Environment, provided the computational ...

Reston, Va. (November 11, 2014) - A novel study demonstrates the potential of a novel molecular imaging drug to detect and visualize early prostate cancer in soft tissue, lymph nodes and bone. The research, published in the November issue of the Journal of Nuclear Medicine, compares the biodistribution and tumor uptake kinetics of two Tc-99m labeled ligands, MIP-1404 and MIP-1405, used with SPECT and planar imaging.
Prostate cancer is the most commonly diagnosed non-skin cancer in the United States, and it is second only to lung cancer as the leading cause of cancer ...

If you're a native of rural Mozambique who contracts HIV and becomes symptomatic, before seeking clinical testing and treatment, you'll likely consult a traditional healer.
Your healer may well conclude that your complaints are caused by a curse, perhaps placed upon you by a neighbor or by the spirit of an ancestor. To help you battle your predicament, the healer will likely cut your skin with a razor blade and rub medicinal herbs into the cut.
A recent survey of symptomatic HIV-positive people in rural Mozambique, led by Carolyn Audet, Ph.D., M.A., assistant professor ...

New research from the Johns Hopkins Bloomberg School of Public Health suggests that HIV-infected adults are at a higher risk for developing heart attacks, kidney failure and cancer. But, contrary to what many had believed, the researchers say these illnesses are occurring at similar ages as adults who are not infected with HIV.
The findings appeared online last month in the journal Clinical Infectious Diseases.
Researchers say these findings can help reassure HIV-infected patients and their health care providers.
"We did not find conclusive evidence to suggest that ...

New Haven, Conn.--The phrase "tears of joy" never made much sense to Yale psychologist Oriana Aragon. But after conducting a series of studies of such seemingly incongruous expressions, she now understands better why people cry when they are happy.
"People may be restoring emotional equilibrium with these expressions," said Aragon, lead author of work to be published in the journal Psychological Science. "They seem to take place when people are overwhelmed with strong positive emotions, and people who do this seem to recover better from those strong emotions."
There ...

With both wolf proposals shot down by Michigan voters on election day, the debate over managing and hunting wolves is far from over.
A Michigan State University study, appearing in a recent issue of the Journal of Wildlife Management, identifies the themes shaping the issue and offers some potential solutions as the debate moves forward.
The research explored how different sides of the debate view power imbalances among different groups and the role that scientific knowledge plays in making decisions about hunting wolves. These two dimensions of wildlife management ...
