A systematic policy approach to changing the food system and physical activity environments to prevent obesity

As obesity prevention becomes an increasing health priority in many countries, including Australia<br>and New Zealand, the challenge that governments are now facing is how to adopt a systematic<br>policy approach to increase healthy eating and regular physical activity. This article sets out a<br>structure for systematically identifying areas for obesity prevention policy action across the food<br>system and full range of physical activity environments. Areas amenable to policy intervention can<br>be systematically identified by considering policy opportunities for each level of governance (local,<br>state, national, international and organisational) in each sector of the food system (primary<br>production, food processing, distribution, marketing, retail, catering and food service) and each<br>sector that influences physical activity environments (infrastructure and planning, education,<br>employment, transport, sport and recreation). Analysis grids are used to illustrate, in a structured<br>fashion, the broad array of areas amenable to legal and regulatory intervention across all levels of<br>governance and all relevant sectors. In the Australian context, potential regulatory policy<br>intervention areas are widespread throughout the food system, e.g., land-use zoning (primary<br>production within local government), food safety (food processing within state government), food<br>labelling (retail within national government). Policy areas for influencing physical activity are<br>predominantly local and state government responsibilities including, for example, walking and<br>cycling environments (infrastructure and planning sector) and physical activity education in schools<br>(education sector). The analysis structure presented in this article provides a tool to systematically<br>identify policy gaps, barriers and opportunities for obesity prevention, as part of the process of<br>developing and implementing a comprehensive obesity prevention strategy. It also serves to<br>highlight the need for a coordinated approach to policy development and implementation across<br>all levels of government in order to ensure complementary policy action.<br>
