“When asked to conjure an image of a patient living with an eating disorder, I imagine many people picture a young, thin woman. This reflects two common stereotypes: that eating disorders only affect women, and that all people with eating disorders are low-weighted. In fact, clinical experience and an evolving field of research show that many males struggle with eating disorders,” says Scott Hadland, MD, MPH, from the Division of Adolescent/Young Adult Medicine at Boston Children’s Hospital.
Similarly, parents and health care providers may see gay, lesbian and bisexual youth in terms of their sexual identities and forget that these teens may face body image and weight control issues as well.
Two recent studies published by researchers at Boston Children’s debunk these stereotypes and may change the way parents and providers think about eating disorders and risky weight control behaviors in all teens.
Alison Field, ScD, also from Boston Children’s Division of Adolescent Medicine, published a study Nov. 4 in JAMA Pediatrics which examined how eating disorders affect teenage boys. Hadland’s study, published Oct. 30 in the Journal of Adolescent Health, focused on risky weight control behaviors—such as fasting for more than 24 hours, using diet pills, and vomiting or using laxatives—among gay, lesbian and bisexual youth. Pediatric Dose spoke with both researchers about their findings and the implications for managing these populations.
Pediatric Dose: Do boys and girls have similar concerns about their weight and physique?
Field: Males and females have very different concerns about their weight and appearance. While girls tend to be more concerned with thinness, boys tend to focus on muscularity. Our study, which reviewed responses of 5,527 adolescent males to the “Growing Up Today Study” questionnaire, every 12 to 36 months from 1999 through 2010, showed that 9.2 percent of boys reported high concerns with muscularity, while 2.5 percent were concerned about thinness and 6.3 percent were concerned with both aspects of appearance.
Pediatric Dose: How might this affect diagnosis of eating disorders among males?
Field: The diagnostic criteria for eating disorders emphasize anorexia nervosa and bulimia and recently recognized binge eating disorder. Anorexia and bulimia are characterized by an excessive influence of weight and physique on self-evaluation, with patients focused on being thin or losing weight.
Most eating disorder assessments reflect these criteria and may overlook boys concerned about their weight and shape but who want to be more muscular. This may be the male equivalent of girls who are very concerned with their weight and who use vomiting or laxatives to lose or maintain weight.
Pediatric Dose: Did the research reveal other risky health behaviors among adolescent males?
Field: Males concerned about muscularity and who used potentially unhealthy supplements, growth hormone and steroids to enhance their physique were approximately twice as likely to start binge drinking frequently and much more likely than their peers to start using drugs. Boys concerned with thinness were more likely to develop depressive symptoms.
A total of 2.9 percent of respondents had full or partial criteria binge-eating disorder, and nearly one-third reported infrequent binge eating, purging or overeating.
Pediatric Dose: What about gay, lesbian and bisexual teens? Are risky weight-control behaviors prevalent among sexual minorities?
Hadland: We suspected these behaviors were higher among sexual minority youth and discovered they are alarmingly common.
We reviewed data from 12,984 high school students who responded to the Massachusetts Youth Risk Behavior Survey in odd years from 2003 to 2009.
We found risky weight control behaviors are common among all teens. One in 10 heterosexual males and two in 10 heterosexual females fasted for 24 hours or longer, used diet pills or vomited or misused laxatives in the month preceding the survey.
These rates increased to approximately one in three among sexual minority youth.
Pediatric Dose: Are there other differences among sexual minorities that might explain the findings?
Hadland: It may be that sexual minority youth face a unique set of stressors, such as social isolation and stigmatization.
We also observed that compared with heterosexual females, lesbians and bisexual females were more likely to self-perceive as being a healthy weight despite being overweight or obese. Compared with heterosexual males, heterosexual males with prior same-sex partners and bisexual males were more likely to see themselves as overweight despite being of healthy weight or underweight.
It may be that body image ideals differ between sexual minority teens and their heterosexual peers.
Pediatric Dose: Do you have any recommendations for primary care providers?
Hadland: Clinicians should be aware that risky weight control behaviors, such as food restriction, misuse of diet products, self-induced vomiting and laxative misuse, are extremely common among all teens and more common among sexual minorities. If a teen identifies as a sexual minority, the health care provider should ask about these behaviors.
Field: It’s important to be aware that some adolescent males may be so preoccupied with their weight and shape that they are using unhealthy methods to achieve the physique they desire.
