Chubby cheeks and climate change: childhood obesity as a sustainable development issue

The rise of obesity is one of today's biggest societal challenges. Indeed, the obesity epidemic is not only impairing individuals' lives, but also societies' sustainability, most notably with regard to the social, the cultural and the economic dimension. Thus, to halt obesity has become a goal in several political sustainability strategies. The focus is on children since their health behaviour is expected to have a strong impact on consumers in adulthood. To fight childhood obesity, the challenge is to develop the ‘right’ policy toolbox. One complicating aspect amongst others is the numerousness of actors involved. To find a policy mix and assess its consequences for all actors, it is essential to understand the underlying mechanisms – the impact of external and internal factors on children's health behaviour. Tools such as regulation, information and education appear to be insufficient to curb this unsustainable consumption behaviour. One promising avenue to strike a new path is to exploit the possibilities of choice architecture as proposed by behavioural economics. The purpose of this paper is threefold: first, to develop the conceptual nexus between obesity and sustainable development against the backcloth of obesity and sustainability research; second, based on a human ecological model, to outline selected influencing factors of childhood obesity; and third, to sketch the options of market and consumer policy actors to curb the pandemic.
