Bariatric Surgery and Eating Disorders: A Double-Edged Sword

Jacqueline 5 Comments

The high prevalence of eating pathology prior to bariatric surgery reduces the likelihood of what researchers have termed “optimal” weight loss post surgery. However, such weight loss is in part due to post-surgical complications like “dumping” (rapid gastric emptying because digestive systems cannot process the food) or vomiting that can develop into conscious efforts to lose weight. Conceicao et al. (2013a) describe, for example, one patient who deliberately binged and purged on foods that would make her vomit spontaneously.

These kinds of results raise a number of questions:

  • How prevalent are eating disorders (EDs) post-bariatric surgery?
  • What are the risk factors for developing an ED?
  • To what extent is the surgery itself a potential trigger?

PREVALENCE OF DISORDERED EATING AMONG INDIVIDUALS SEEKING BARIATRIC SURVERY

Researchers interested in bariatric surgery have explored how often those seeking bariatric surgery engage in disordered eating or have EDs. Prevalence rates vary between studies depending … Continue reading →

Exploring Family Based Treatment for Eating Disorders in China

Jacqueline 6 Comments

Not much is known about eating disorders in China, especially compared to its East Asian counterparts of Hong Kong and Japan. It would appear that researcher-practitioners in China are not publishing much data about eating disorders in the country; in fact, the author of the study I’ll be looking at in this post, Joyce Ma, practices primarily in Hong Kong. In this study, Ma explores China-specific patterns of ED presentation and how they relate to the social context. As she notes, treatment models have been slow to develop from the mother-blaming paradigm proposed by Chen (1990), which recommended that eating disorder patients be isolated from their parents. No other study appears to have been done (at least that she cites) using evidence-based modalities.

In her study, she reports on the results of treatment with 10 families in a Shenzhen clinic, with patients of a relatively wide age range – … Continue reading →

Poverty and Eating Disorders in Hong Kong

Jacqueline

Eating disorders are typically seen as an illness of the middle class, with most patients coming from that socioeconomic group. However, the invisibility of poorer patients within eating disorder research in part reflects the barriers to treatment that they face, including both cost and lower levels of awareness. This paper, written by a Hong Kong social work professor, Joyce Ma, focuses less on the process of eating disorder recovery, highlighting instead the context of treatment. She discusses how family dynamics and socioeconomic status come into play in her encounters with 7 Hong Kong teenagers from low-income families.

While her sample size is very small, it reveals a more diverse — and less body image-focused –disease pathway than most American studies, with Ma breaking down the precipitating factors as follows (patient numbers in brackets):

  • Constipation (1)
  • Desire to be thin (3, 7)
  • Relationship issues (6)
  • Parental conflicts (5)
  • Poverty (2, 4)

Culture and Eating Disorders: Treatment Outcomes in Singapore and Hong Kong

Jacqueline

In this last post about eating disorders in Singapore, I’ll write about the one Singapore-based retrospective outcome study in relation to a similar retrospective study conducted in Hong Kong.

In the Singapore study, researchers reviewed the charts of 94 patients diagnosed with anorexia nervosa from 1992 to 2004 at the National University Hospital, looking back from the time of the study. They didn’t contact any of the subjects for follow-up. 49 were first seen as inpatients, 34 as outpatients, and 11 were seen as outpatients but later admitted. The hospital doesn’t have a specialized ED service, so the authors relied on dietetic notes that unfortunately don’t provide a full picture of the patients’ eating disordered behaviors and cognitions.

The authors wrote about patient ‘improvement’ (not recovery!) as making a weight gain of at least 0.5 kg, or about 1 pound. 83% of their patients attended follow up appointments, which lasted … Continue reading →

Culture and Eating Disorders: The Thin Ideal in Singapore

Jacqueline

The paper I’m writing about in this post is a master’s thesis published elsewhere in adapted form as a book chapter – not the usual subject here, admittedly. However, for lack of more detailed qualitative research, it’s quite useful in fleshing out some of the observations in more descriptive studies on Singaporean eating disorder patients. This origin is one among a few other caveats to bear in mind; among them, Isono Maho’s ethnography does not aim to be a representative study of ED patients in Singapore, but rather a reflection on the aspects of Singapore culture that related to her interviewees’ particular experiences. Some of the themes Isono Maho found in this data set, nevertheless, help to supplement other studies’ findings, including those indicating that patients with eating disorders in Singapore tend to:

  • Present with body image concerns
  • Attribute comments and judgments from others as factors in their eating disorders.

Culture and Eating Disorders: A Singaporean Perspective — Part 2

Jacqueline

I previously looked at two retrospective studies of anorexia patients in Singapore, which primarily concerned female patients. In this study, Tan et al (2014) looked at 72 male-identified patients diagnosed with all forms of eating disorders.

  • 1% had anorexia nervosa (15.3% binge-purge subtype, 20.8% restrictive subtype)
  • 3% had bulimia nervosa (27.8% purge subtype, 5.6% non-purge subtype)
  • 5% had EDNOS
  • 9% had BED

The mean age at intake was 19.9 years old; patients were mainly students (41.7%) and national servicemen (41.7%). Compulsory army service (National Service) usually takes place in the two years after high school graduation, though some may defer until completing further studies. The typical age range for those in National Service is 19-24.

Of the patients in the study, 88.9% identified a precipitating factor for their eating disorder, including being overweight (59.7% reported pre-morbid obesity) and having people make comments about their body. 68.1% of patients … Continue reading →

Culture and Eating Disorders: A Singaporean Perspective — Part 1

Jacqueline 2 Comments

Some previous posts on this blog have explored whether eating disorders might (or might not) be considered culture-bound, or in other words specific to or presenting specifically in certain cultures. If you consider eating disorders to be “culture bound,” they would present primarily in Western cultures, with non-Western cultures ‘receiving’ eating disorder pathology through Westernization. In this post, I explore eating disorders in the Singaporean context to continue to unpack the relationship between culture and eating disorders. Singapore is an interesting place in which to look at eating disorders (not just because I live there) because it complicates the idea of “culture-boundedness.”

Studies have been conducted in Asia; primarily in Hong Kong and to a lesser extent Japan. Most notably, Lee (1991) found non-fat-phobic presentations in Hong Kong supported by Ngai, Lee & Lee (2000) (see this post for more on the Ngai study). Singapore is … Continue reading →
