Excessive Exercise in Eating Disorders

Excessive exercise (EE) is common among eating disorder patients. Indeed, in the study I’ll write about today, 39% of patients engaged in EE. Previous studies have tried to find psychopathological and personality correlates of EE but the results have been inconsistent. Some studies have suggested that impulsivity and addictiveness are highly correlated with EE whereas others found that anxious and depressive traits were more closely associated.

In a retrospective case series study involving outpatients with AN and BN, Penas-Lledo et al. found higher levels of anxiety and depression… among those who were identified as exercising excessively. The authors claimed that exercise might serve to reduce anxiety and stress in individuals with AN. In a similar study with adolescent inpatients with AN, Holtkamp et al. found that anxiety significantly predicted variance in exercise levels. These investigators proposed that anxiety symptoms in combination with food restriction contributed to increased levels of physical

Self-Denial, Secrecy and Deliberate Lying in Eating Disorders

I don’t know how many times I’ve said, “I’ve already eaten, thanks,” “No thanks, I’m going be eating later,” or “I’d love to, but I’ve got a stomach ache,” when I actually hadn’t eaten, wasn’t going to eat later, and didn’t have a stomach ache. Why did I do that? Did I realize I had, or was developing, an eating disorder? How long did it take for that realization to click? And once it did, did I stop lying to avoid eating with others or did I do it more?

A lot of questions spring up when you start thinking about secrecy, denial, and lying as it related to eating disorders. And answering these questions by having to remember what you thought when you first began to show signs of your eating disorder is hard. It is hard for many reasons, but one reason is that the we feel about … Continue reading →

Eating Disorders Among Lesbian and Bisexual Women

The hardest part of science blogging is picking an article to blog about. In times when I’m indecisive–when I spend hours sifting through the literature, inevitably creating several draft posts before deciding each article isn’t interesting enough–I turn to the list of topics that have been suggested by readers. The last suggestion I received was “eating disorders in the lesbian community.” It is a great suggestion, but I thought my search wouldn’t turn up much. But, to my surprise, it did turn up some studies.

But please, don’t expect too much: it is not a well-studied area, and most of the data comes from self-reported questionnaires, which are not particularly reliable:

  • First, there’s selection bias: the 50% or so of people who return the surveys could be different in significant ways from the 50% that don’t. For example, in a survey about mental health, perhaps individuals that have

Should Insurance Companies Cover Residential Treatment for Eating Disorders?

Should insurance companies cover residential treatment for eating disorders?  The price tag is high, about $1,000/day on average, but evidence of treatment effectiveness  is astonishingly low. Practically nil, as I’ve recently discovered. Despite spending my free time punching away different keywords into the PubMed search bar, I came up with very little. And you know what I think? I think treatment centers should be embarrassed. And I think, wow, maybe insurance companies have a point? (A scary thought! I don’t actually think they do, though – but then, I just can’t wrap my head around for-profit healthcare, having lived all my life with socialized healthcare, and loving it.)

Carrie over at ED-Bites recently blogged about the fact that there a dearth of evidence-based treatment for eating disorders. It is a complicated issue, I know, but I do think that any organization or center that offers treatment (especially … Continue reading →

Does Too Much Exposure to Thin Models Cause Eating Disorders? Anorexia, Bulimia in Blind Women

As many of you already know, Vogue has recently banned models that are “too-thin” (and “too young”). It is a big step in the right direction, no, a huge step, and one deserving an applause, that’s according to an article on allvoices.com. Cue a drop in the prevalence of eating disorders, right? The logic in most articles, whether implicit or explicit, seems to be: no more skinny models = no more girls aspiring to be like skinny models = no more eating disorders.

Health of models belonging to both genders has been a growing issue in the past, especially after the death of two models in 2006-2007 from what the doctors blame to their acute eating disorders. This important step by Vogue targets not just skinny models, but also the impact they have on the young minds of girls and boys by presenting an image of perfection that

Eating Disorders and Psychiatric Comorbidities in Female Inpatients

Patients with eating disorders commonly exhibit comorbid psychiatric disorders, including anxiety, depression and OCD. The presence of comorbid disorders has been shown to exacerbate the severity and chronicity of the disorder, and unfavourably affect treatment outcome. Moreover, comorbid disorders may necessitate specialized treatment plans that take into account all the co-occuring disorders. Recovery from an eating disorder is hard enough, but when it is complicated by depression and severe anxiety, it can be a lot harder.

Nonetheless, commonly co-occuring psychiatric disorders may also provide researchers and clinicians clues about the etiology of eating disorders, the underlying neuronal processes as well as possible pharmacological interventions.

Researchers have been identifying disorders that commonly co-occur with eating disorders and studying the differences in co-morbidity between disorders. I picked one to write about today, it is a study by Blinder and colleagues that came out in 2007. It is by no means the best, … Continue reading →
