Call For Abstracts: Canadian Obesity Summit, Toronto, April 28-May 2, 2015

COS2015 toronto callBuilding on the resounding success of Kananaskis, Montreal and Vancouver, the biennial Canadian Obesity Summit is now setting its sights on Toronto.

If you have a professional interest in obesity, it’s your #1 destination for learning, sharing and networking with experts from across Canada around the world.

In 2015, the Canadian Obesity Network (CON-RCO) and the Canadian Association of Bariatric Physicians and Surgeons (CABPS) are combining resources to hold their scientific meetings under one roof.

The 4th Canadian Obesity Summit (#COS2015) will provide the latest information on obesity research, prevention and management to scientists, health care practitioners, policy makers, partner organizations and industry stakeholders working to reduce the social, mental and physical burden of obesity on Canadians.

The COS 2015 program will include plenary presentations, original scientific oral and poster presentations, interactive workshops and a large exhibit hall. Most importantly, COS 2015 will provide ample opportunity for networking and knowledge exchange for anyone with a professional interest in this field.

Does Facebook Use Promote Eating Disorders?

facebook_button_eu3gSocial media are not just a means of sharing your life with the world – they also open your life to praise (likes and positive comments) or criticism.

Thus, it is easy to see how avid use of such platforms (especially those with ample picture posts) can potentially promote body image and weight obsessions in those who may not be quite confident and happy about their appearance.

That this may not just be an interesting theory is suggested by two studies by Annalise Mabe and colleagues from Florida State University, published in the International Journal of Eating Disorders.

In the first study 960 female college students completed an Eating Attitudes Test that included Dieting and Bulimia/Food Preoccupation subscales with items such as “I eat diet foods” and “I give too much time and thought to food.”

Duration of Facebook use was assessed with the question “How much time do you spend on Facebook per week?” with options ranging from 0 to >7 hours (average used tended to be just over 2 hours per week).

This study found a small but statistically significant positive relationship between the duration of Facebook use and disordered eating.

In the second study, 84 women, who had participated in the first study and endorsed Facebook use on a weekly basis were randomization to either spending 20 mins on their facebook account or finding information about the ocelot on Wikipedia and YouTube.

Participants with greater disordered eating scores endorsed greater importance of receiving comments on their status, and greater importance of receiving “likes” on their status. Those with greater eating pathology reported untagging photos of themselves more often and endorsed comparing their photos to their female friends’ photos more often.

Participants in the control group demonstrated a greater decline in weight/shape preoccupation than did participants who spent 20 min on Facebook. Furthermore post hoc comparisons supported a significant decrease in weight/shape preoccupation in controls.

Facebook use resulted in a preoccupation with weight and shape compared to an internet control condition despite several multivariate adjustments.

As the authors discuss, their finding,

“indicates that typical Facebook use may contribute to maintenance of weight/shape concerns and state anxiety, both of which are established eating disorder risk factors.”

In terms of practical implications of these findings, the authors suggest that,

“Facebook could be targeted as a maintenance factor in prevention programs. For example, interventions could address the implications of appearance-focused comments such as “you look so thin” or “I wish I had your abs,” in perpetuating the thin ideal on Facebook, much as “fat talk” perpetuates this ideal in everyday conversations. An adaption of the “Fat Talk Free” campaign as well as adaptations of media literacy programs could encourage girls and women in the responsible use of social media sites.”

Clearly, this appears to me as a rather fertile area for further research.

I’d certainly be interested in hearing about your experience with facebook and any effects it may have had on your body image or eating behaviours.

Obesity Guru – Fringed and Confused

header_Fringe_festival2014As I look forward to a wild and crazy week of performances and shenanigans at North America’s largest and longest running 33rd International Fringe Theatre festival here a short glimpse of a few TV interviews about my “Obesity Guru” show.

If this is a way to get scientific messages about obesity to the public – so be it! I for one plan to have as much fun with this as I can.

Given that all 7 shows for next week are sold out (they were sold out 3 days before start of the festival), I can only assume that a lot of Edmontonians are interested in this rather quirky approach to science communication.

Who Likes Fat Jokes?

sharma-obesity-not-funnyAs I prepare for my upcoming comedy show, “Weighty Confessions of an Obesity Guru” at the 33rd Edmonton International Fringe Theatre Festival, I am swamped with media interest in the notion of someone doing comedy on obesity.

Obviously, anyone who knows me or has been to one of my shows knows that I do not make “fat jokes” – or jokes about fat people.

This may be surprising to many in the comedy industry, as there is no shortage of comedians who think fat jokes are funny – and they apparently have the audiences that agree.

So, one may ask, who are these people who laugh at fat jokes?

This question was recently studied by Jacob Burmeister and Robert Carels in an article published in Psychology of Popular Media Culture.

The researchers examined the responses of 500 individuals who viewed 7 video clips from popular film and TV programs featuring weight-related humor.

Participants were asked to rate each clip on a number of dimensions including funniness and offensiveness.

They also completed measures of attitudes and beliefs toward obesity including dislike for obese persons, belief in the controllability of body weight, and a belief in stereotypes about obese persons.

As the researchers (and most of us would have predicted), the greater the participants’ dislike for obese persons and their belief in disparaging stereotypes about obesity, the funnier they thought the jokes were.

Similarly, the more the participants believed in disparaging stereotypes about obesity and that obesity is controllable, the less likely they were to consider weight-related humor distasteful.

While none of this is surprising, these finding do align nicely with disparagement humor theory.

Thus, the widespread use of weight-related humor is nothing else than a direct reflection of the widespread misconceptions and stereotypic beliefs about obesity that feed weight bias and discrimination.

These are exactly the issues that I aim to address in my show – perhaps it is now time to laugh about people who laugh at fat jokes.

4th Canadian Obesity student Meeting (COSM 2014)

Uwaterloo_sealOver the next three days, I will be in Waterloo, Ontario, attending the 4th biennial Canadian Obesity Student Meeting (COSM 2014), a rather unique capacity building event organised by the Canadian Obesity Network’s Students and New Professionals (CON-SNP).

CON-SNP consist of an extensive network within CON, comprising of over 1000 trainees organised in about 30 chapters at universities and colleges across Canada.

Students and trainees in this network come from a wide range of backgrounds and span faculties and research interests as diverse as molecular genetics and public health, kinesiology and bariatric surgery, education and marketing, or energy metabolism and ingestive behaviour.

Over the past eight years, since the 1st COSM was hosted by laval university in Quebec, these meetings have been attended by over 600 students, most presenting their original research work, often for the first time to an audience of peers.

Indeed, it is the peer-led nature of this meeting that makes it so unique. COSM is entirely organised by CON-SNP – the students select the site, book the venues, review the abstracts, design the program, chair the sessions, and lead the discussions.

Although a few senior faculty are invited, they are largely observers, at best participating in discussions and giving the odd plenary lecture. But 85% of the program is delivered by the trainees themselves.

Apart from the sheer pleasure of sharing in the excitement of the participants, it has been particularly rewarding to follow the careers of many of the trainees who attended the first COSMs – many now themselves hold faculty positions and have trainees of their own.

As my readers are well aware, I regularly attend professional meetings around the world – none match the excitement and intensity of COSM.

I look forward to another succesful meeting as we continue to build the next generation of Canadian obesity researchers, health professionals and policy makers.
