Ideology, obesity and the social determinants of health: a critical analysis of the obesity and health relationship

Based on a critical review of the obesity and health literature we provide five models of how the hypothesized obesity and health relationship is conceptualized. We then apply these models to make sense of how recent Canadian public health reports and clinical practice guidelines conceptualize the issue of obesity, its causes and health effects, and appropriate responses. We show how conformity to dominant models of the obesity and health relationship by health sciences researchers, public health workers, and the media lead to activities that rather than promoting health, actually threaten it. These dominant models - and the activities derived from them - do so by diverting attention from the far more important issues of the quality and distribution of the social determinants of health. These approaches also stigmatize heavy individuals, doing little to promote their health. For these reasons, we call for an end to seeing obesity as a significant health issue.
