Strategy 1-1: Enhance the physical and built environment. Communities, organizations, community planners, and public health professionals should encourage physical activity by enhancing the physical and built environment, rethinking community design, and ensuring access to places for such activity.Potential actions include• communities, urban planners, architects, developers, and public health professionals developing and implementing sustainable strategies for improving the physical environment of communities that are as large as several square miles or more or as small as a few blocks in SIZE in ways that encourage and support physical activity; and• communities and organizations developing and maintaining sustainable strategies to create and/or enhance access to places and programs where people can be physically active in a safe and enjoyable way. Strategy 1-2: Provide and support community programs designed to increase physical activity. Communities and organizations should encourage physical activity by providing and supporting programs designed to increase such activity.Potential actions include• developing and implementing ongoing physical activity promotion campaigns that involve high-visibility, multiple delivery channels and multiple sectors of influence;• developing and implementing physical activity strategies that fit into people’s daily routines—strategies that are most effective when tailored to specific interests and preferences; and• developing and implementing strategies that build, strengthen, and maintain social networks to provide supportive relationships for behavior change with respect to physical activity. Strategy 1-3: Adopt physical activity requirements for licensed child care providers. State and LOCAL child care and early childhood education regulators should establish requirements for each program to improve its current physical activity standards.Potential actions include• requiring each licensed child care site to provide opportunities for physical activity, including free PLAY and outdoor play, at a rate of 15 minutes PER hour of care; as a minimum, immediate first step, each site providing at least 30 minutes of physical activity per day for half-day programs and 1 hour for full-day programs.Strategy 1-4: Provide support for the science and practice of physical activity.Federal, state, and local government agencies should make physical activity a national health priority through support for the translation of scientific evidence into best-practice applications.For federal-level government agencies, potential actions include• the Department of Health and Human Services establishing processes for the regular and routine communication of scientific ADVANCES in understanding the health benefits of physical activity, particularly with respect to obesity prevention (these processes could include, but are not limited to, regularly scheduled updates of the Physical Activity Guidelines for Americans and reports of the U.S. Surgeon General); and• all federal government agencies with relevant interests developing priority strategies to promote and support the National Physical Activity Plan, a trans-sector strategy for increasing physical activity among Americans.For state and local health departments, potential actions include• developing plans and strategies for making promotion of physical activity a health priority at the state and local levels
