Research Says Fat Friends and Poor Education helps People Think Thin

24.07.2008
Research by economists at the University of Warwick, Dartmouth College, and the University of Leuven, finds that people are powerfully but subconsciously influenced by the weight of those around them.

Without being aware of it, the researchers believe, human beings keep up with the weight of the Joneses. For a whole society, this can lead to a spiral of imitative obesity. The researchers will present their results on Friday July 25th at a National Bureau of Economic Research conference in Cambridge Massachusetts in a paper entitled Imitative Obesity and Relative Utility at the NBER Summer Institute on Health Economics.

Using data on 27,000 Europeans from 29 countries, the researchers find that nearly half of European women feel overweight. Less than a third of males feel overweight.

The authors suggest that whether for reasons of job promotions or finding a mate it is someone’s weight relative to others that matters. They show that overweight perceptions and dieting decisions are influenced by people’s comparisons with others of the same age and gender.

Highly educated Europeans hold themselves to a particularly tough standard, the research shows. For any given level of Body Mass Index (BMI), somebody with a university degree feels much fatter than someone with low educational qualifications.

Overall, the researchers believe that a person’s "utility" (an economic term roughly meaning satisfaction levels) depends on their own weight relative to the weight of those around them. They suggest that it is easier to be fat in a society that is fat.

However, the authors also found a significant gender split. Females were much more prone, for any given BMI value, to feel overweight. For European women, weight dissatisfaction and overweight perceptions depended crucially upon not just their own absolute BMI, but also upon their BMI relative to other women of exactly the same age in their country. Conversely, being overweight tended not to be a significant issue for men if many of those around them were as overweight as they were.

Professor Andrew Oswald at the University of Warwick, one of the researchers, said "Consumption of calories has gone up but that does not tell us why people are eating more. Some have argued that obesity has been produced by cheaper food, but if fatness is a response to greater purchasing power, why do we routinely observe that rich people are thinner than poor people?"

He said: "A lot of research into obesity, which has emphasized sedentary lifestyles or human biology or fast-food, has missed the key point. Rising obesity needs to be thought of as a sociological phenomenon not a physiological one. People are influenced by relative comparisons, and norms have changed and are still changing."

However, the authors found a significant gender split. Females were much more prone, for any given BMI value, to feel overweight. For European women, weight dissatisfaction and overweight perceptions depended crucially upon not just their own absolute BMI, but also upon their BMI relative to other women of exactly the same age in their country.

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
