(Press-News.org) Young women who are attracted to both sexes or who are unsure about who they are attracted to are more likely to develop an eating disorder than those attracted to only one sex, according to a new study from Drexel University.
However, the results of the study suggest that females attracted to the same-sex are no more likely to experience disordered eating symptoms than their peers with opposite-sex attractions. This finding is contrary to previous assumptions that same-sex attraction plays a protective role against eating pathology in females.
"The results of this study suggests there may be notable differences in disordered eating symptoms across LGBQ persons," said lead author Annie Shearer, outcomes research assistant for Drexel University's Center for Family Intervention Science in the College of Nursing and Health Professions. "Given the severe physical and emotional repercussions of eating disorders, these findings underscore the need for primary care physicians to ask about both sexuality and disordered eating symptoms during routine visits."
The study also found that males who were attracted to other males or both sexes had higher rates of eating disorders than males only attracted to the opposite sex, which is supported by previous research.
"While there is a lot of research indicating gay and bisexual men exhibit higher rates of eating disorders than heterosexual men, findings have been mixed with respect to women," said Shearer. "Moreover, bisexual and - to an even greater degree - questioning persons are often excluded from these studies."
The study, "The Relationship between Disordered Eating and Sexuality amongst Adolescents and Young Adults," is now available online and will appear in a forthcoming print issue of Eating Behaviors, an international peer-reviewed scientific journal publishing human research on the etiology, prevention and treatment of obesity, binge eating and eating disorders in adults and children.
In order to examine disordered eating symptoms and sexuality in adolescents and young adults, the researchers recruited participants from ten primary care sites in Pennsylvania and administered a Behavioral Health Screen - a web-based screening tool that assesses psychiatric symptoms and risk behaviors - during a routine visit. More than 2,000 youths, ages 14-24, were surveyed.
Participants' eating behaviors were assessed through questions such as, how often do you think that you are fat even though some people say that you are skinny? How often do you try to control your weight by skipping meals? And, how often do you try to control your weight by making yourself throw up?
Sexual attraction was computed based on participants' gender and to which sex participants reported they felt most attracted to: either males, females, both or not sure. In order to define sexual behavior, participants were asked whom they had engaged in sexual activities: males, females or both.
As expected, males who were attracted to other males exhibited significantly higher disordered eating scores than those only attracted to members of the opposite sex. Males who engaged in sexual activities with other males also exhibited significantly higher scores than those who only engaged in sexual activities with females.
Amongst females, there were no significant differences in disordered eating scores between females who were only attracted to females and those only attracted to males. Those who reported being attracted to both sexes, however, had significantly higher scores, on average, than those only attracted to one sex.
More surprisingly, according to the researchers, females who were unsure of who they were attracted to reported the highest disordered eating symptoms scores of all.
"This study highlights the need to increase sensitivity to the unique needs of sexual minority youth as a group and for the particularly sub groups in that population," said Guy S. Diamond, PhD, associate professor in the College of Nursing and Health Professions, director of the Couple and Family Therapy Doctoral Program and director of the Center for Family Intervention Science, who co-authored the study. "But it also demonstrates the value of standardized, comprehensive screening for mental health concerns in primary care."

London, 2 September 2015: With 32,773 registrations this year (1), ESC Congress 2015 broke yet another record in attendance. "We are proud to have brought together so many delegates and the latest research from all over the world," said ESC President, Professor Fausto Pinto, from Portugal.
"By 2030, 40% of Europeans will suffer from some form of CVD," said Prof Fausto Pinto, ESC President, "so what is going on in our congress is relevant to everyone, not only health professionals." (2)
Despite improvements in mortality and morbidity, CVD remains the main killer ...
The word "apple", as we pronounce it, is a sequence of sounds (phonemes) that we use whenever we want to refer to the object it indicates. If we did not know that a referential relationship exists between the sound and the object it would be impossible for us to use, and learn, a language. Where does this implicit knowledge come from, and how early in human development does it manifest? This is the question Hanna Marno and her SISSA colleagues Marina Nespor and Jacques Mehler in a collaboration with Teresa Farroni, from the University of Padova, attempted to answer in a ...
Meningiomas are a type of brain tumor that form on membranes covering the brain and spinal cord just inside the skull. They occur at an annual incidence of up to 13 per 100 000, and approximately 20% of these exhibit aggressive behavior and burden patients with tumor recurrences as well as infiltration of the surrounding bone, brain, or soft tissue.
Dr. Matthias Preusser of the Medical University Vienna - General Hospital AKH and Coordinator of this study says, "High-grade meningiomas are characterized by prominent infiltration with tumor-associated macrophages and angiogenesis. ...
This news release is available in German. What did the universe look like shortly after it came into being? The ALICE experiment (A Large Ion Collider Experiment) at CERN in Switzerland concerns itself with this question. At the largest particle accelerator in the world, the Large Hadron Collider (LHC), researchers let lead nuclei and protons collide at the highest beam energies to date. The temperatures thereby created are 100,000 times higher than those in the center of the Sun. "A state is created that is very similar to the one after the Big Bang," explains Laura ...
(Boston)--There is strong evidence that the protein complex APC/C may function as a tumor suppressor in multiple cancers including lymphoma, colorectal and breast cancer, and now melanoma. A new study has revealed that a genetic mutation leading to repression of a specific protein, Cdh1, which interacts with APC/C, is present in melanoma cancer cells.
The study, led by researchers at Boston University School of Medicine (BUSM), reports sporadic mutations in the APC/C protein complex, specifically in the essential protein component Cdh1, which may predispose humans to ...
The study, published in the journal Financial Stability, introduces a new method that allows researchers to estimate the systemic risk that emerge from multiple layers of connectivity.
"Systemic risk is the risk that a significant part of the financial system stops working--that it cannot perform its function," says IIASA Advanced Systems Analysis program researcher Sebastian Poledna, who led the study. For example if a major bank fails, it could trigger the failure of other financial institutions that are linked to it through loans, derivatives, securities, and foreign ...
Scientists have developed a simple process to treat waste coffee grounds to allow them to store methane. The simple soak and heating process develops a carbon capture material with the additional environmental benefits of recycling a waste product.
The results are published today, 03 September 2015, in the journal Nanotechnology.
Methane capture and storage provides a double environmental return - it removes a harmful greenhouse gas from the atmosphere that can then be used as a fuel that is cleaner than other fossil fuels.
The process developed by the researchers, ...
Although most of the world's biodiversity is below ground, surprisingly little is known about how it affects ecosystems or how it will be affected by climate change. A new study demonstrates that soil bacteria and the richness of animal species belowground play a key role in regulating a whole suite of ecosystem functions on Earth. The authors call for far more attention to this overlooked world of worms, bugs and bacteria in the soil.
Ecosystem functions such as carbon storage and the availability of nutrients are linked to the bugs, bacteria and other microscopic ...
CAMBRIDGE, Mass. (September 2, 2015) - Altering the protein recycling complexes in human cells, including cancer cells, allows the cells to resist treatment with a class of drugs known as proteasome inhibitors, according to Whitehead Institute scientists.
"This is why some cancers can be so difficult to treat with chemotherapy, because the cells can be in different states--some sensitive to treatment and some resistant to treatment, all in the same tumor," says Sandro Santagata, a former visiting scientist in the lab of Whitehead Member Susan Lindquist. Santagata is now ...
Their pregnancies are carried by the males but, when it comes to breeding, seahorses have more in common with humans than previously thought, new research from the University of Sydney reveals.
Seahorses are famed for being part of the only family in the animal kingdom (Syngnathidae) in which the male is responsible for pregnancy. What hasn't been known until now is the degree to which male seahorses nourish and protect their embryos in their brood pouch during the 24-day gestation period.
Findings co-authored by Dr Camilla Whittington from the University's School of ...
