Preconception nutrition: building advocacy and social movements to stimulate action.

Action to improve preconception nutrition is a collective, societal responsibility. We believe that the Developmental Origins of Health and Disease (DOHaD) society is ideally placed to facilitate the development of a global agenda for preconception nutrition which recognises the societal importance of nutrition for young women and men, and supports them in optimising their nutritional status for the benefit of the next generation. In this paper, we outline four key actions that can be taken by the members of DOHaD's international society located across 67 countries, and nine regional societies, to demonstrate this leadership role. The recommended actions to place preconception nutrition at the top of national and regional agendas include (i) continuing to build the scientific evidence, (ii) monitoring of progress made by governments and commercial companies, (iii) developing advocacy coalitions that unite individuals and organisations around common policy options and (iv) working with partners to develop an emotive and empowering preconception nutrition awareness campaign. Collectively, these actions hold the potential to develop into a preconception nutrition social movement to invoke high-level government support and across-sector policy action, while raising public demand for action and engaging corporate actors.
