Promoting physical activity and healthy diets by modifying the social and/or physical environment at local level: a scoping review of evidence-based policy actions.

Background We aimed to map evidenced-based policy actions proposed by public health institutes or organizations to promote physical activity and healthy diets by modifying the social and/or physical environment at the local level. Methods We conducted a scoping review to identify relevant evidence-based policy actions proposed by public health institutions. We used a two-step strategy to identify government-supported public health institutes or organizations that generate evidence-based recommendations for policy actions. We included policy actions if they 1) aimed at increasing physical activity or improving diet; 2) focused on modifying the physical or social environments; 3) were implemented at the local or community level; 4) were expressed as a concrete action rather than a general aim; and 5) were described explicitly as being based on evidence. Results Starting from 121 public health institutes, we identified 8 relevant organizations and reviewed 63 guidelines or reports that included actions to promote healthy diets and physical activity. Of the 540 proposed actions on diet and 358 on physical activity, 118 met the inclusion criteria. Given that many of the actions were recommended by multiple institutes, we synthesized the information in the infographics to provide recommendations on diet and physical activity in outdoor and indoor settings and schools. Conclusions Public health institutes have generated a wide range of evidence-based recommendations for the promotion of healthy diets and physical activity by modifying the physical and social environment that can be implemented in local settings. Future actions should address barriers to implementing these recommendations and analyze the determinants of local policy decisions.
