MSU research indicates testosterone could guard against eating disorders

05.03.2008
Testosterone appears to protect people against eating disorders, providing further evidence that biological factors – and not just social influences – are linked to anorexia and bulimia, according to new research findings at Michigan State University.

An ongoing, six-year study of 538 sets of twins in Michigan indicates that females who were in the womb with male twins have lower risk for eating disorder symptoms than females who were in the womb with female twins. Previous animal research has shown that females in the womb with males are exposed to higher levels of testosterone.

The new findings – from a team of MSU psychology researchers – are published in the March issue of the Archives of General Psychiatry, out today.

“From these findings, it appears that testosterone exposure could have a protective effect against the development of disordered eating,” said project researcher Kelly Klump, MSU associate professor of psychology and president of the Academy for Eating Disorders.

According to the academy, 10 percent or more of late adolescent and adult women report symptoms of eating disorders at any given time.

Klump said researchers have known for years that women are more affected by eating disorders than men and that “some of that is due to social influences such as beauty ideals around thinness for women that we don’t have for men.”

But the question of whether biological influences also play a role has been an understudied area, she said. The fast-growing MSU Twin Registry, which includes more than 1,200 sets of twins ages 6 to 30, provided a substantial research population, said Klump, who runs the registry with Alexandra Burt, assistant professor of psychology.

Kristen Culbert, lead researcher on the project and a doctoral student in clinical psychology, said while societal differences have typically been used to explain why women are more affected by eating disorders, the new research is “significant in suggesting a biological explanation.”

Being raised with a brother did not account for the effects, Culbert added. That’s because researchers also looked at females who were not twins but grew up with a brother and found that those females were at higher risk for eating disorder symptoms than females who shared a womb with and were raised with a male.

Klump said the findings could ultimately help improve the treatment of eating disorders.

“More and more animal researchers are discovering how testosterone affects brain development,” she said. “So if we know there are protective factors against eating disorders, we can potentially determine which areas of the brain might be particularly sensitive to prenatal testosterone exposure and use that information to identify new biological treatments.”

Also on the research team were Burt and Marc Breedlove, Barnett Rosenberg professor of neuroscience.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
