Study finds surprising links between bullying and eating disorders

CREDIT: ILLUSTRATION BY MARK DUBOWSKI FOR DUKE MEDICINE Being bullied in childhood has been associated with increased risk for anxiety, depression and even eating disorders. But according to new research, it's not only the victims who could be at risk psychologically, but also the bullies themselves. Researchers at Duke Medicine and the University of North Carolina School of Medicine were surprised to find that in a study of 1,420 children, those who bullied others were twice as likely to display symptoms of bulimia, such as bingeing and purging, when compared to children who are not involved in bullying. The findings are published in the December issue of International Journal of Eating Disorders. "For a long time, there's been this story about bullies that they're a little more hale and hearty," said lead author William Copeland, Ph.D., associate professor of psychiatry and behavioral sciences at Duke University School of Medicine. "Maybe they're good at manipulating social situations or getting out of trouble, but in this one area it seems that's not the case at all. Maybe teasing others may sensitize them to their own body image issues, or afterward, they have regret for their actions that results in these symptoms like binge eating followed by purging or excess exercise." The findings come from an analysis of interviews from the Great Smoky Mountains Study, a database with more than two decades of health information on participants who enrolled at age 9. The data is considered a community sample and not representative of the U.S. population, but offers clues to how children ages 9 to 16 could be affected. Participants were divided into four categories - children who were not at all involved in bullying; victims of bullying; children who sometimes were victims and sometimes were instigators; and children who were solely bullies, repeatedly abusing other children verbally and physically, socially excluding others, and rumor mongering, without ever becoming a victim themselves. The researchers were not surprised to find that victims of peer abuse were generally at increased risk for eating disorders. Children who were victims of bullying were at nearly twice the risk of displaying symptoms of anorexia (11.2 percent prevalence compared to 5.6 percent of children who were not involved in bullying) and bulimia (27.9 percent prevalence compared to 17.6 percent of children not involved in bullying). Children who were both bullies and victims had the highest prevalence of anorexia symptoms (22.8 percent compared to 5.6 percent of the children not involved in bullying) and also the highest prevalence of binge eating (4.8 percent of children as compared to less than 1 percent of uninvolved children) and vomiting as a way to maintain their weight. But the impact of bullying behavior on those who were bullies was also significant, with 30.8 percent of bullies having symptoms of bulimia compared to 17.6 percent of children not involved in bullying. All of these behaviors can have devastating effects on the long-term health of children, said Cynthia M. Bulik, Ph.D., a distinguished professor of eating disorders at the UNC School of Medicine and a co-author on the findings. "Sadly, humans do tend to be most critical about features in other people that they dislike most in themselves," Bulik said. "The bullies' own body dissatisfaction could fuel their taunting of others. Our findings tell us to raise our vigilance for eating disorders in anyone involved in bullying exchanges -- regardless of whether they are the aggressor, the victim, or both." Although many children experience lifelong effects, many appear to cope and succeed after such experiences, Copeland said. He and colleagues are examining myriad factors, including looking at financial and educational outcomes, and even if bullying or being victimized is associated with genetic biomarkers. "We want to do a better job of understanding why some people are able to experience the same things as others and be able to get through them without the same consequences," Copeland said. "We really need to understand the resilience in those who have been bullied. That can help us determine the children who are going to need the most attention, and how we can promote those traits in others to increase their resilience." ### In addition to Copeland and Bulik, study authors include Nancy Zucker; Dieter Wolke; Suzet Tanya Lereya; and Elizabeth Jane Costello.

Past weight loss an overlooked factor in disordered eating

PHILADELPHIA (September 24, 2013)— Dieters and weight loss researchers are familiar with the principle: The more weight you've lost, the harder it is to keep it off. A complex and vicious cycle of biological and behavioral factors make it so. But eating disorder research has largely overlooked this influence, and Dr. Michael Lowe, a professor of psychology at Drexel University, has published a flurry of research studies showing that needs to change. "The focus of eating disorder research has very much been on the state of patients' thoughts, beliefs, emotions and personalities," Lowe said. "And while these mental influences are undoubtedly part of the problem, historically there has been very little focus on how their current and past body weights contribute to their eating disorder." Lowe and colleagues' studies – about a dozen on bulimia nervosa have been published in the past several years – show that having an elevated past body weight, and being at a body weight well below highest past weight, may help cause and perpetuate disordered eating. The latest of Lowe's studies was just published in The Journal of Abnormal Psychology, the top journal for eating disorder research, and is the team's first to address this principle in anorexia nervosa. The findings, Lowe says, show that researchers and clinicians need to start taking into account how a person's historical and current body weight contribute to disordered eating. "This fundamentally changes the assumption that the problem is primarily psychological or emotional," Lowe said. The new study, led by doctoral student Laura A. Berner, was based on data collected at the Renfrew Center for eating disorders in Philadelphia, where Lowe is also a consultant. The researchers found that the level of eating disorder symptoms, as well as degree of improvement during treatment, depends on how much weight patients with anorexia nervosa had lost from their previous highest weight (a measure called "weight suppression"), how much they currently weigh and the interaction between the two LSW Continuing Education After controlling for patients' body mass index (BMI, which is a known indicator of disease severity), they found that patients with greater weight suppression had more severe symptoms of anorexia than patients whose low weight was closer to their historical highest weight. Standard measures of disordered eating such as shape concerns, eating concerns, binge eating, depression and menstrual abnormalities were correlated with weight suppression, current BMI, or both. Lowe said that researchers and clinicians who already use weight or BMI as an absolute measure of eating disorder severity should also consider weight suppression as a relative measure. These findings also may have important implications for treatment. "The standards for treating anorexia nervosa are all about 'how much weight do they need to gain to meet a minimally healthy body weight for their height,'" Lowe said. "What we've rarely asked, is 'what is this patient's weight history?'" Lowe said his ongoing research suggests that the answer is that many patients weighed more than their peers before developing anorexia nervosa. "If the patient's body somehow 'remembers' that past higher weight, then even at the minimally healthy body weight she is still going to be struggling mightily to maintain her weight," Lowe said. "That perspective is new. It suggests that future treatments might work toward finding a healthier 'balance point' between what patients once weighed and what they currently weigh." "It is really helpful to have more than one way to look at weight in the eating disorders; we now have evidence that absolute weight and relative weight are both important in predicting difficulties in our work towards full recovery," said Dr. Susan Ice, vice president and chief medical officer of The Renfrew Center. "And it is immensely satisfying to find that science has discovered that there is physical memory or a kind of 'wisdom' in the body." ### Lowe and his research team were recently funded by the National Institute of Mental Health to further investigate the role of these weight-related variables on bulimia nervosa. Individuals with symptoms of bulimia who are interested in participating in this federally funded study may call 215-762-1313 or email TEDS@drexel.edu for additional information. Another research laboratory at Drexel, the Laboratory for Innovations in Health-Related Behavior Change, is recruiting participants who have experienced binge eating problems but do not engage in compensatory behaviors such as self-induced vomiting or laxative use. One project is investigating a new smartphone app for binge eating and the other is evaluating an in-person treatment.

Hunger Pains: Binge-eating disorder linked to lifelong impairments in 12-country study

Binge-eating disorder linked to lifelong impairments in 12-country study Binge-eating disorder, designated only months ago by the American Psychiatric Association as a diagnosis in its Diagnostic and Statistical Manual of Mental Disorders, is associated with substantial lifelong impairments comparable to those of bulimia nervosa, according to a World Health Organization study based on community epidemiological surveys conducted in 12 nations worldwide. The publication of the results online today in Epidemiology and Psychiatric Sciences is timed to coincide with the beginning of Weight Stigma Awareness Week (September 23-27). Although both binge-eating disorder and bulimia involve recurrent episodes of excessive food consumption with experienced loss of control, it had been generally assumed that bulimia carried a greater functional burden of illness owing to its more complex symptom profile. A defining symptom of bulimia, lacking in binge-eating disorder, is inappropriate compensatory behavior such as purging or laxative use to offset the weight gain associated with bingeing. However, compared to matched populations of people with no history of eating disorders, a lifetime history of binge-eating disorder or bulimia each predicted between two- and nearly four-fold increases in current days unable to work or carry out usual activities. Despite the significant challenges that people with these disorders face, both are generally undetected by medical professionals and therefore left untreated. "Binge-eating disorder has been largely ignored by health care providers, but it has a tremendous cost to the physical and psychological well-being of people with the disorder," said Ronald Kessler, McNeil Family Professor of Health Care Policy at Harvard Medical School and senior author of the paper. "When all of the cases of the disorder are taken together, the elevated levels of depression, suicide and lost days at work represent substantial costs to society." The study found that binge-eating disorder and bulimia nervosa both typically arose during adolescence and were associated with a range of later-onset mental disorders (including depression and anxiety disorders) and physical disorders (such as musculoskeletal disorders and diabetes). Early-onset binge-eating disorder was associated with subsequent low rates of employment among men, low rates of marriage among women and high rates of work disability among both men and women. The researchers concluded that the adverse effects of binge-eating disorder and bulimia on subsequent functioning were largely the result of these later-onset comorbidities. This finding, the researchers said, raises the possibility that expanded efforts at early detection and treatment of eating disorders during the vulnerable school years might help prevent the onset of subsequent mental and physical disorders and impairments associated with these disorders. In independent commentaries published in the same journal, international experts on eating disorders Janet Treasure and Cynthia Bulik wrote that the evidence in the report argues strongly for proceeding with clinical effectiveness trials to evaluate the long-term effects on adult health and well-being of early detection and treatment of binge-eating disorder and bulimia among students. The study was based on community surveys in 12 countries. Researchers interviewed a total of 22,635 adult respondents. Binge-eating disorder was roughly twice as common as bulimia across the countries studied, which included the U.S., several countries in Latin America (Brazil, Colombia, Mexico), a number in Europe (Belgium, Italy, Netherlands, Northern Ireland, Portugal, Romania, Spain) and New Zealand Professional Counselor Continuing Education ### The analysis for this paper was carried out in conjunction with the World Health Organization World Mental Health (WMH) Survey Initiative. These activities were supported by the U.S. National Institute of Mental Health (R01MH070884) and the Mental Health Burden Study (Contract number HHSN271200700030C) and by a number of government agencies in the other participating countries, as well as by foundations and industry sponsors.

Psychotropic Medications Are Prescribed Appropriately Among U.S. Teens, National Study Finds

Prescribed psychotropic medications are not being misused or overused among U.S. youth, according to a study using nationally representative data sponsored by NIMH. The study was published December 3, 2012, online ahead of print in the Archives of Pediatric and Adolescent Medicine. Background Psychotropic medications affect the brain chemicals associated with mood and behavior. Some studies and media reports have raised concerns about their use among youth. However, much of the concern stems from information found in anecdotal reports, small clinical samples, or insurance databases rather than on representative samples of U.S. youth with clinical assessments of emotional and behavioral disorders. Studies from regional community samples have found widely varying rates, which can lead to skewed perceptions. For example, different studies have found a wide range of stimulant medication use for attention deficit hyperactivity disorder (ADHD)—from 7 percent to 72 percent—likely due to methodological and regional differences. As a result, it has been difficult to get a clear, accurate understanding of medication use among youth. Kathleen Merikangas, Ph.D., of NIMH and colleagues collected information on specific medication use in the National Comorbidity Study-Adolescent Supplement (NCS-A), a nationally representative, face-to-face survey from 2004 of more than 10,000 teens ages 13 to 18.The teens were asked questions that helped to ascertain information about mental disorders and service use. A previous report published in October 2010 using data from the NCS-A indicated that about 20 percent of U.S. youth are affected by some type of mental disorder during their lifetime serious enough to affect their functioning. In this most recent analysis, the researchers examined patterns of prescribed medication use among youth who met criteria for a wide range of mental disorders. Psychotropic medications that were examined include antipsychotics, antidepressants, and stimulants Professional Counselor Continuing Education Results of the Study Among those youth who met criteria for any mental disorder, 14.2 percent reported that they had been treated with a psychotropic medication. Teens with ADHD had the highest rates of prescribed medication use at 31 percent, while 19.7 percent of those with a mood disorder like depression or bipolar disorder were taking psychotropic medication. Among those with eating disorders, about 19 percent were taking a psychotropic medication, and 11.6 percent of those with anxiety disorders reported taking medication. Very few youth reported use of antipsychotic medications. They were most frequently used by youth with severe bipolar disorder (1.7 percent) or a neurodevelopmental disorder such as autism (2.0 percent). Approximately 2.5 percent of teens without a diagnosed mental disorder were prescribed a psychotropic medication. Among these youth, 78 percent reported having a previous mental or neurodevelopmental disorder and associated psychological distress or impairment. Significance The data suggest that most adolescent youth who are taking psychotropic medications have serious behavioral, cognitive or emotional disturbances. The findings also showed that youth being treated by a mental health professional were more likely to be receiving appropriate medication as opposed to those being treated within general medicine or other settings. However, more research is needed on medication use among children younger than age 13. Reference Merikangas K, He J, Rapoport J, Vitiello B, Olfson M.
