Eating disorder research tends to focus on girls and women. Which makes sense: eating disorders disproportionately affect women. However, it isn’t just the research on eating disorders that focuses on women: it’s the entire history of eating disorders as a diagnosis. The first descriptions of anorexia nervosa by William Gull and bulimia nervosa by Gerald Russell were both based primarily on observations of female patients (although Russell did include two men). Therefore, it’s possible that our basic construction of eating disorders is based on a specifically female experience.
One example of this is the focus on weight loss as a cardinal component of eating disorders (barring binge eating disorder). This is often attributed to the pursuit of a “thin ideal” created by our culture; however, this thin ideal doesn’t necessarily apply to men. Whilst women encounter pressure to be thin, evidence suggests that men encounter pressure to be more muscular—a … Continue reading →
Although the words “anorexia nervosa” typically conjure up images of emaciated bodies, eating disorders characterized by dietary restriction or weight loss can — and do — occur at any weight. However, precisely because anorexia nervosa is associated with underweight, doctors are less likely to identify eating disorders among individuals who are in the so-called “normal” or above normal weight range, even if they have all the other symptoms of anorexia nervosa.
Clearly, this is a problem.
For one, there is no evidence that eating disorder not otherwise specified (EDNOS) — a diagnosis given to individuals who do not fulfill all of the criteria for anorexia nervosa or bulimia nervosa — is less severe or less dangerous than full syndrome anorexia nervosa. As I’ve blogged about, individuals with EDNOS have comparable mortality rates (see: EDNOS, Bulimia Nervosa, as Deadly as Anorexia Nervosa in Outpatients) and similar (sometimes even more severe) … Continue reading →
Is anorexia nervosa a subtype of body dysmorphic disorder (BDD)? Well, probably not, but don’t click the close button just yet. In this post, I’ll explore the relationship between anorexia nervosa and BDD, and discuss how understanding this relationship might help us develop better treatments for both disorders.
Despite the fact that there are obvious similarities between the disorders, studies exploring the relationship between BDD and AN are few and far between. In a recent paper, published in the Clinical Psychology Review, Andrea Hartmann and colleagues summarized the current state of knowledge in the field. The review compared clinical, personality, demographic, and treatment outcome features of AN and BDD. I’ll summarize the key points of the paper in this post.
(I will be focusing on the relationship between AN and BDD, as opposed to EDs and BDD, because that’s the scope of the review article.)
First, what is body … Continue reading →
When most people think of bulimia nervosa, they think of binge eating and self-induced vomiting. While that is not incorrect, it is not the full picture either. In the current edition of the Diagnostic and Statistical Manual (DSM-IV), there are two subtypes of bulimia nervosa: purging (BN-P) and nonpurging (BN-NP). The difference lies in the types of compensation methods: patients with BN-P engage in self-induced vomiting, or the misuse of laxatives, diuretics, or enemas whereas patients with BN-NP use fasting or excessive exercise to compensate for binge eating.
How common in BN-NP? It is very hard to say. A small population-based study in Finland (less than 3,000 participants) found that 1.7% of the sample that bulimia nervosa, 24% had BN-NP (or 0.4% of the entire sample) (Keski-Rahkonen et al., 2009). (I couldn’t find much else on prevalence of BN-NP.)
Unfortunately, however, there’s been very little research … Continue reading →
A really fun aspect of blogging is seeing what search terms lead people to my blog; a frustrating side-effect is not being able to interact with those people directly. This entry is, in part, an attempt to answer a common question that leads individuals to my blog. Common question or search queries are variants of the following (these are actual search terms that led to this blog, I corrected spelling mistakes): “do models cause eating disorders in women?”, “pictures of skinny models linked to eating disorders”, “do the images of models in magazines cause eating disorders?”, “eating disorders relating to thin models”, “psychiatrists thought on how skinny models are causing eating disorders”, “thin models are to blame for eating disorder.”
Well, you get the point.
I briefly started tackling the notions that the “thin ideal” promoted by Western media is to blame for the prevalence of eating disorders and a … Continue reading →
