Individual responsibility for reducing obesity: the unintended consequences of well intended messages

To the Editor: In a recent article that appeared in newspapers such as Melbourne’s The Age and Sydney Morning Herald on 19 Jan 2011,1 one of us (P Z) argued that it is both ineffective and inaccurate to blame those who are overweight and obese for their health problems. It was highlighted that our social, economic, cultural and physical environments are all “obesogenic”,2 acting as barriers to achieving a healthy lifestyle. The article by Proietto in the August 2011 issue of the Journal similarly argued that the obesogenic environment, and its interaction with a person’s genetic make-up, is to blame for the increasing prevalence of overweight and obesity.3

Neglecting to address the role of environmental factors in lifestyle disease may lead to a number of unintended negative consequences. First, healthy eating and being physically active are not easy choices. If attempts are not as successful as first hoped, and if the response from health professionals is simply “try harder”, feelings of guilt and despair can result, which then make it even harder to engage in healthy behaviours.

Second, a sole emphasis on individuals’ responsibility for their own health has led governments at all levels in Australia to be passive on this issue. Governments seek to protect us in other ways (eg, legislation to restrict the use and advertising of tobacco), so they now need to be encouraged to take steps towards reducing the obesogenic nature of our environment (eg, introducing policy that ensures affordable and sustainable fruit and vegetable production).4

Finally, focusing on individual health behaviours alone may create or reinforce a social stigma around obesity and related chronic conditions, such as type 2 diabetes.5 When individual behaviour change is the sole focus of prevention and management efforts, the subtext is that the individual is to blame if he or she develops the condition. The astonishing and immediate public response to the aforementioned newspaper article — almost 300 comments were posted online on The Age and Sydney Morning Herald websites alone within hours — reflected an entrenched attitude of blame towards people who are overweight or obese. Given that type 2 diabetes can only be prevented in about 60% of cases,6 these comments reveal and perpetuate a limited understanding of the multiple causes of lifestyle diseases.

It remains critical to encourage people to pursue healthy lifestyle choices. However, addressing the obesogenic elements of our environment is just as important. Encouraging patients to become involved in organisations such as The Parents’ Jury, an online network dedicated to improving children’s food and physical activity environments (www.parentsjury.org.au), or to become familiar with community-based initiatives such as Victoria Walks (www.victoriawalks.org.au) may be beneficial. More broadly, it is important for health professionals and their professional bodies to make known to governments their support of policy and other initiatives that make our environ-ment conducive to healthy choices.
