title: [Environmental approaches in the prevention of obesity in children and adolescents].
abstract: This article aims to provide a structured review of how to create settings and environments that prevent the development of childhood overweight and obesity. It also describes which institutions and levels are responsible for environmental (global) approaches in obesity prevention and which evidence exists in terms of process and outcomes of different preventive measures. Environmental approaches in disease prevention deal with social and technical-material conditions of daily living, as those conditions significantly influence health behavior. Strategies that focus on the obesogenic environment are considered increasingly important in the prevention of obesity in children and adolescents. They can be applied at different levels (e.g., schools, communities). These interventions should aim to improve the availability of healthy foods and physical activity facilities, e.g., by provision of healthy meals and foods in schools, restaurants, and stores and by price reductions of healthy foods. Physical activity can be supported by creating attractive green spaces and playgrounds in schools and cities, improving sidewalk networks and a supportive pedestrian environment, and implementing walk-to-school projects. On a national level, policies and legislation can support changes in the social and situational environments, e.g., relating to catering in schools or TV advertisement. The practice of environmental approaches is complex, because many stakeholders from different sectors have to be involved. This may account for the observation that environmental approaches are currently underrepresented in obesity prevention.
