Research in the health sciences has been highly successful in revealing the aetiologies of many morbidities, particularly those involving the microbiology of communicable disease. This success has helped form a narrative to be found in numerous public health documents, about interventions to reduce the burden of non-communicable diseases (e.g., obesity or alcohol related pathologies). These focus on tackling the purported pathogenic factors causing the diseases as a means of prevention. In this paper, we argue that this approach has been sub-optimal. The mechanisms of aetiology and of prevention are sometimes significantly different and failure to make this distinction has hindered efforts at preventing non-communicable diseases linked to diet, exercise and alcohol consumption. We propose a sociological approach as an alternative based on social practice theory.(A virtual abstract for this paper can be found at: https://www.youtube.com/channe l/UC_979cmCmR9rLrKuD7z0ycA).Keywords: public health, non-communicable disease, social practice, behaviour change, alcohol
IntroductionThis paper considers the way that simple causal narratives dominate political and policy discourse about the prevention of non-communicable diseases (NCDs). While we consider, specifically, the case of English policies, we think analogous approaches could be applied in other countries. These narratives impute mechanisms. The idea is borrowed from the aetiology of infectious or communicable disease; once you know the mechanisms you can intervene on it and prevent disease. In NCDs, instead of germs and viruses causing illness, the putative causal pathway runs from human behaviour, through risk, to disease and then on to prevention. The behaviour, its associated risks, the disease and its prevention are treated as if they are part of the same causal chain (see Department of Health 2004, Department of Health/Public Health England 2015a). The simplified narrative acts as a heuristic, that is, a shorthand way of thinking that allows simple but inaccurate answers to complicated problems to frame decision making (Kahneman 2011). The simple narrative conceals the vital distinction between mechanisms of aetiology and mechanisms of prevention. In the following two sections 2 and 3, we argue that the mechanisms of aetiology and mechanisms of prevention must be distinguished. In the 4 and 5 Sociology of Health & Illness Vol. 40 No. 1 2018 ISSN 0141-9889, pp. 82-99 doi: 10.1111/1467 sections, we propose a non-reductionist sociological approach to health and disease, based on social practice theory and on a brief consideration of nineteenth century public health in England. Finally, in the sixth and seventh sections, we illustrate our argument with discussions about the prevention of smoking, obesity and using social practice theory show how this helps illuminate preventive approaches to alcohol misuse.
