be very useful. There is also a growing interest in influencing children’s physical activity in child care centers and after school programs.
Strategy 5: Promote policies that reduce sedentary screen time.
There is observational evidence supporting the action step under this strategy. Moreover, the CDC’s Task Force on Community Preventive Services recommends behavioral interventions to reduce screen time.
Strategy 6: Develop a social marketing program that emphasizes the multiple benefits for children and families of sustained physical activity.
The action step for this strategy that recommends “a social marketing program that emphasizes the multiple benefits for children and families of sustained physical activity” is supported by intervention evidence. The other action steps under this strategy have limited evidence.
As mentioned often in this report, the evidence base for local government actions is limited in certain areas, but steadily accumulating. The shortcomings in the evidence base should not discourage action, but should encourage continuing research, evaluation, and analysis whenever possible, especially in those areas in which evidence is lacking. When local governments evaluate the results of their childhood obesity prevention actions, it is important to ensure that this information is broadly disseminated.
