Social Network Analysis of the Obesity Research Boot Camp

bootcamp_pin_finalRegular readers may recall that for the past nine years, I have had the privilege and pleasure of serving as faculty of the Canadian Obesity Network’s annual Obesity Research Summer Bootcamp.

The camp is open to a select group of graduate and post-graduate trainees from a wide range of disciplines with an interest in obesity research. Over nine days, the trainees are mentored and have a chance to learn about obesity research in areas ranging from basic science to epidemiology and childhood obesity to health policy.

Now, a formal network analysis of bootcamp attendees, published by Jenny Godley and colleagues in the Journal of Interdisciplinary Healthcare, documents the substantial impact that this camp has on the careers of the trainees.

As the analysis of trainees who attended this camp over its first 5 years of operation (2006-2010) shows, camp attendance had a profound positive impact on their career development, particularly in terms of establishing contacts and professional relationships.

Thus, both the quantitative and the qualitative results demonstrate the importance of interdisciplinary training and relationships for career development in obesity researcher (and possibly beyond).

Personally, participation at this camp has been one of the most rewarding experiences of my career and I look forward to continuing this annual exercise for years to come.

Guest Post: My Weight Is Not Measured In Pounds

Fitness Header ColorToday’s guest post comes from Andrea Matthes, a Certified Personal Trainer and blogger, who I met at the annual meeting of the Obesity Action Coalition in Orlando – the post speaks for itself.

I recently attended the Obesity Action Coalition’s annual Your Weight Matters Convention and got the opportunity to hear Dr. Sharma’s keynote presentation titled, “Health is Not Measured in Pounds.” I found myself sitting in my chair, agreeing so emphatically that I was full-body nodding at the waist. By the end of his speech, I couldn’t contain myself– I jumped out of my chair making the first, very loud clap that echoed through the room, only to be followed by hundreds of other claps and a full-house standing ovation. Dr. Sharma’s message was something I needed to hear. Not because it was a new theory to me, but because up until that hour, his theory was what I was experiencing first-hand.

I am 5 feet, one inch tall and weigh 165lbs (when slightly dehydrated). At my current height/weight my BMI is 31.2, also known as: OBESE. A word that is often associated with laziness, overeating, diabetes, high blood pressure, bad cholesterol and overall ill health. According to this number, I need to lose at least 35lbs if I want to reach the “normal” range in order to be considered “healthy”.

Can I just tell you how frustrating that is?

I am living an exceptionally healthy, full and active lifestyle. My blood pressure is perfect, my cholesterol levels are great, and my A1C is consistently normal. My daily life consists of running, jumping, lifting heavy objects, and eating a diet that most people would consider ideal. I am extremely proud of the lifestyle I live. I am able to climb mountains, run races, surf, ski, and flip a perfectly executed cartwheel at the drop of a hat. Yet, I am told that in order to be healthy, I need to lose weight!

How ridiculous is that?

It’s extremely ridiculous and unfair that I have to live with a label that is based on a fancy formula for size; a label that says I need to lose weight in order to avoid potential misdiagnoses, higher insurance premiums, and social stigma. It’s unfair that my TRUE health has very little to do with pounds and everything to do with how I live my life. This is what my obesity looks like:

I am a running, swimming, cycling, heavy-lifting, nutrient-eating, LIFE-LOVING, 5-foot-one-inch-tall, 37-year-old woman who also weighs 165lbs which leaves me with a label that misrepresents the life I live and my health!

I may be obese according to BMI but that does not mean I am unhealthy.

My obese body is strong, it is capable, it is HEALTHY. In fact, my obese body is healthy enough to do things that many skinny people can’t do. So weigh me all you want, but please, do not measure my HEALTH in pounds.

The Cultural Drivers and Context of Obesity

sharma-obesity-family-watching-tvIn my continuing review of not too recent publications on obesity, I found this one by Hortense Powdermaker, Professor of Anthropology, Queens College, Flushing, New York, published in the Bulletin of the New York Academy of Medicine in 1960.

The following quotes could all have been written last week:

“We eat too much. We have too much of many things. According to the population experts, there are too many people in the world, due to the decline in mortality rates. A key theme in this age of plenty-people, food, things-is consumption. We are urged to buy more and more things and new things: food, cars, refrigerators, television sets, clothes, etcetera. We are constantly advised that prosperity can be maintained only by ever-increasing consumption.”

“…physical activity is almost non-existent in most occupations, particularly those in the middle and upper classes. We think of the everincreasing white-collar jobs, the managerial and professional groups, and even the unskilled and skilled laborers in machine and factory production. For some people there are active games in leisure time, probably more for males than females. But, in general, leisure time activities tend to become increasingly passive. We travel in automobiles, we sit in movies, we stay at home and watch television. Most people live too far away to walk to their place of work.”

“The slender, youthful-looking figure is now desired by women of all ages. The term “matronly”, with its connotation of plumpness, is decidedly not flattering. Although the female body is predisposed to proportionately more fat and the male to more muscle, the plump or stout woman’s body is considered neither beautiful nor sexually attractive.”

“The desire for health, for longevity, for youthfulness, for sexual attractiveness is indeed a powerful motivation. Yet obesity is a problem. We ask, then, what cultural and psychological factors might be counteracting the effective work of nutritionists, physicians, beauty specialists, and advertisements in the mass media?”

“Although there are probably relatively few people today who know sustained hunger because of poverty, poor people eat differently from rich people. Fattening, starchy foods are common among the former, and in certain ethnic groups, particularly those from southern Europe, women tend to be fat. Obesity for women is therefore somewhat symbolic for lower class. In our socially mobile society this is a powerful deterrent. The symbolism of obesity in men has been different. The image of a successful middle-aged man in the middle and upper classes has been with a “pouch”, or “bay-window”, as it was called a generation ago.”

The paper goes on to discuss some (rather stereotypic) notions about why some people overeat and others don’t – an interesting read but nothing we haven’t heard before.

Nevertheless, given that this paper was written over 50 years ago – one wonders how much more we’ve actually learnt about the cultural aspects of this issue – it seems that we are still discussing the same problem as our colleagues were half a century ago.

Perhaps it really is time for some new ideas.

Obesity Tip Sheet For Occupational Therapists

OT obesity tip sheet AHS Oct 2014

October is Occupational Therapist Month, an event celebrated by the Canadian Association of Occupational Therapists in a nation-wide campaign involving billboards and bumper stickers.

Reason enough to turn my readers attention to a “tip sheet” developed by members of the Alberta Health Services’ Bariatric Resource Team that explains when to refer their patients with obesity to an occupational therapist.

The preamble to this sheet notes that,

“Occupational therapists promote health and well being for people with obesity by facilitating engagement in occupations of everyday life, including addressing occupational performance issues in the areas of self-care, productivity and leisure. This can impact quality of life, including how people with obesity participate in their daily lives and in health and weight management activities.”

Occupational therapy referral may be indicated for a person with obesity presenting with challenges ranging from occupational engagement to completing simple activities of daily living.

Happy OT month!

Practical Guide To Obesity Prevention in Schools in Developing Countries

Practical Guide To Obesity Prevention in School-Aged ChildrenObesity in school-age children is not just a problem in the affluent West – this issue if of growing importance in countries where one may not quite expect this to be an issue like South Asia or Africa.

Now, researchers from the University of Montreal and McGill University have released a comprehensive practical guide to developing and implementing obesity prevention programs for school-aged children and adolescents in developing countries.

As the authors discuss,

“What is most challenging in low and middle-income countries is the urgency of preventing obesity while also tackling the problem of malnutrition. Again, the school setting is likely the most appropriate to address the dual burden of malnutrition, but interventions are needed at different stages of the lifecycle, beginning with girls, in order to break the intergenerational cycle of malnutrition and its impact on vulnerability to obesity and other chronic diseases.”

This guide is a product of TRANSNUT (for nutrition transition), a WHO Collaborating Centre comprised of 10 researchers from the Department of Nutrition and other units of the University of Montréal.

In the words of the authors,

“This manual is designed to provide a hands-on guide for health and nutrition professionals to plan, implement and evaluate obesity prevention programmes for school-age children and adolescents in developing countries, particularly in the school setting. Several practical tools are suggested, including for the assessment of obesity and of its proximal determinants, that is, eating and physical activity patterns. Models and conceptual frameworks are discussed because action has to be grounded in sound theory. We provide a 5-step guide to planning healthy nutrition promotion and obesity prevention interventions, which we adapted from the PRECEDE-PROCEED of Green. The steps consist of community and individual assessments, identification of targets for change(community, family, individual level), choice of objectives, design of programme methods, and procedures for theevaluation. In order to foster effective programmes to promote healthy nutrition and lifestyle among school-agechildren and adolescents, we discuss theoretical models of behaviours change that may be appropriate (Health Belief Model, Theory of Planned Behaviour, Social Cognitive Theory, Stages of Change, Transtheoretical Model).”

This document should provide an interesting read to anyone interested in the prevention of childhood obesity in developing countries or elsewhere.
