Changing behaviour at scale to prevent NCDs

This chapter describes behaviour change at scale using interventions that can impact the behaviour of individuals at the scale of entire populations, or specific groups within populations, by altering aspects of the contexts or environments in which the behaviour occurs. Implementing interventions that change behaviour at this scale most often requires legislative, regulatory and fiscal policies. By creating environments that encourage healthy behaviour for everyone, interventions that target the whole population have the potential additional benefit of increasing the effectiveness of interventions targeting individuals. A wide range of examples of population-level interventions to change behaviour at scale to prevent NCDs are described. Key issues for implementing interventions to change behaviour at scale include strengthening political leadership and governance, engaging with industry and the private sector while safeguarding against corporate interference in policy, and increasing public demand.
